Project Manager (Chandra Bomu)

Project Engineers (4).

Site engineers (2).

Senior engineers (2).

Safety Engineers (2).

Quality engineers (3).

Electrical Engineer (1).



RECOMMENDATIONS (labour and Employee benefits)

Labour scarcity, there should be some more labour employed in site.

For plastering only 4 members are there, hence work is getting delayed.

Labour is not following few of the safety and SOP practices, which should be

avoided.

Labour is getting tired because of the overtime work in few cases, to avoid that

Pleasant Music is recommended in site during their work.

Labour shifts to be followed.

Employees are assigned multiple tasks like…

(Planning dept., assigned work of quantity estimation, Safety dept. assigned work of

Time Office entry.) Which creates more burden on the employees, so separate

supervisors/engineers are employed for particular work.

Due to continuous work without any holidays the employees are feeling stressed, so

at least once in a week should be Holiday.

Employees are working for more than 12 hours in a day, and when the concreting in

night takes place even they are staying for late nights, which creates less enthusiasm

in work in the next day. So there should be a holiday, the next day of overtime or

there should be Employee shifts to make the employees active during work.

Temporary Lift should be provided for Staff to monitor the work effectively, since

it is a 14 floor structure, it’s getting difficult for the staff to go up to the working

area several number of times and check the progress of work.

Rewards for employees to be given to recognise their services to the company.

There should be coordination between the employees of various Departments in

project, daily or weekly the employees are to be bought to a single area and

discussions are to be carried out. Daily meetings should be there.

Health check-ups quarterly once should be done to employees, since Employee

Health increase the productivity of work.



2.6) RMC PLANT (READY MIX CONCRETE)

The site MASSEYS is having a RMC plant installed at site.

The contractor for Plant is Southern Engineers.

RMC Plant

Salient features of RMC (Ready mix concrete):

The plant has a capacity to deliver 8 cu.m of concrete per hour.

For casting the entire slab area of plinth area 10,500 sft, it requires 150-

160cu.m of concrete.

Admixture veraplast MC 543 is used.

M sand (manufacture sand) is used in concreting.

River sand is used for mortar mix. (1:3)

GGBS (Ground-granulated blast-furnace slag) is used as replacement for

cement, along with cement.

Water cement ratio: 0.34.

Admixture dosage: 0.3 %.

The aggregates are watered before mixing.



Standard operating procedure for RMC plant

Don’t accept the concrete after 3 hours of Mixing.

The horizontal section of pipe should be at least 7 metres before the vertical bend is

put.

Reduce the length of pipe to the minimum to reduce frictional losses and excessive

strain on the pump.

The pipeline should be independently supported on vertical segment and not on the

shuttering.

Pump rich slurry (1 bag) before pumping concrete to lubricate the inner surface of

pipes.

Advantages in using GGBS:

GGBS perfectly suited to our site MASSEYS (A high rise building) and it is giving

better results when compared to the conventional concrete when tested at site during

cube strength.

Ensures higher durability of structure.

Reduces the temperature rise and helps to avoid early-age thermal cracking.

Improved workability.

It is off-white in colour and substantially lighter than Portland cement. Resultantly it

helps soften the visual impact of large structures such as bridges and retaining walls.

Very economical and reduces the cement cost.

RECOMMENDATIONS

The present RMC plant has a capacity to pump concrete of 8 cu.m per hour.

Which takes more time for concreting the slab.

The slab (including beams) requires 160 cu.m of concrete for casting, so it

takes almost 20 hours for casting a slab. It became a prime factor in delay of

project.

It is recommended to increase the capacity of plant which should pump at

least 20 cu.m of concrete per hour.

Maintenance of RMC plant is not proper, it is recommended to clean the plant

and inspect for every one week.

Pumps which carries concrete should also be cleaned after used.

PILE LOAD TEST PROCEDURE

Test pile preparation

The test pile is cut at the proper level by removing casing and chipping the concrete

and reinforcement bar up to proper level. Reinforcement bars are cut below 75 mm

from proper level where proper finishing of top surface is done with GP2 and stone

chips mortar and the same is allowed for curing for days.

Excavation for Test Pile pit shall be done up to pile cut of level by keeping

sufficient working area around the Pile. Wherever water table is above the Cut off

Level, the test pit shall be kept dry throughout the test period by suitable dewatering

methods.

Equipment and test set up

A steel plate of sufficient thickness shall be placed centrally on the pile head to prevent

it from crushing under applied load. The size of the plate shall not be less than the pile

size or less than the area covered by the base of the hydraulic jack(s).

The datum bars are placed on immovable supports of concrete pillars placed at

3 m away from edge of test pile on both ends. The dial gauges of 0.01mm least count

are fixed to the datum bar duly using magnetic base and the plunger is placed on glass

plates fixed to the bottom plate 4 dial gauges of MITUTOYO make with a least count

of 0.01 mm are placed diametrically opposite location suspended on datum bar

supported on concrete pillar around the pile with the plunger toughing on the glass

plates fixing to the bottom plate. The load is applied to the pile top in increments (steps)

of about 20% of safe load on the pile. Each increment of load is applied as smoothly

and expeditiously as possible. Settlement reading were taken before and immediately

after the application of next increment and at 30 minutes until application of the next

load increment.

Each stage of loading was maintained until the rate of displacement of the pile top is

either 0.1mm in 30minutes or 0.2mm in one hour or till 2 hours whichever occur first.

Loading on pile shall be continued till Applied load reaches two and half times the

assumed safe load or the settlement of pile exceeds a value equivalent to 10% of pile

diameter.

Where yielding of the soil does not occur the full test load shall be maintained on the

pile head for a minimum period of 24 hrs after the last increment of load and settlement

shall be recorded at hourly intervals during this period, however the interval can be

increased to 6 hours to suit the actual site conditions encountered. Unloading shall be

carried out in the same steps as loading. A minimum period of 15 minutes shall be

allowed to elapse between two successive stages of load decrement.



The final rebound shall be recorded 2 hours after the entire test load has been

removed.4 dial gauges of MITUTOYO make with a least count of 0.01 mm are placed

diametrically opposite location suspended on datum bar supported on concrete pillar

around the pile with the plunger toughing on the glass plates fixing to the bottom plate.

The load is applied to the pile top in increments (steps) of about 20% of safe load on

the pile. Each increment of load is applied as smoothly and expeditiously as possible.

Settlement reading were taken before and immediately after the application of next

increment and at 30 minutes until application of the next load increment. Each stage

of loading was maintained until the rate of displacement of the pile top is either 0.1mm

in 30minutes or 0.2mm in one hour or till 2 hours whichever occur first.

Loading on pile shall be continued till Applied load reaches two and half times

the assumed safe load or the settlement of pile exceeds a value equivalent to 10% of

pile diameter. Where yielding of the soil does not occur the full test load shall be

maintained on the pile head for a minimum period of 24 hrs after the last increment of

load and settlement shall be recorded at hourly intervals during this period, however

the interval can be increased to 6 hours to suit the actual site conditions encountered.

Unloading shall be carried out in the same steps as loading. A minimum period of 15

minutes shall be allowed to elapse between two successive stages of load decrement.

The final rebound shall be recorded 2 hours after the entire test load has been removed.

Loading method:

The load shall be applied to the pile in increments of about 20% of the safe

capacity of pile.

Each stage of loading shall be maintained till rate of movement of pile top is not

more than 0.1mm/30 min or 0.2mm /hrs or until 2 hrs have elapsed.

Increment of loading continued till

1) Applied load reaches 3 times the safe vertical load carrying capacity or

2) The maximum l settlement of pile exceeds 10% of dia of pile.

Full test load shall be maintained on the pile head for a minimum period of 24

hrs after the last increment of load has been applied.

Unloading shall be carried out in the same steps as loading minimum of 30

minutes shall be allowed to elapse between two successive stages of load

decrement.

The final rebound shall be recorded 6 hours after entire test load has been

removed.



Assessment of Safe Load:

The safe vertical load carrying capacity of single pile shall be least of

1. Two-third of the final load, at which the total settlement is 12 mm and

2. 50 % of the final load, at which the total settlement equals to 10% of pile

diameter.

Pile load checking

Result of Pile load test

S.No Description Result Remarks

1 Settlement on working load 0.695 mm (387.840MT)

3 Rebound 1.896 mm 4.968-3.072

4 Final settlement 3.072 mm Final settlement

Conclusion: At 900 ø pile, 750 ton of load is applied. Final settlement of pile is 3mm

but the allowable final settlement of pile is 20 mm. Based on the pile load test it ensure

that foundation is at good strength.



3.2) BEAMS

A total of 149 beams are there for a typical floor.

The cross-section of beam is 200x600mm.

Reinforcement bars in beams used are 12mm, 16mm, 20mm, and 25 mm

diameter.

Note: 25 mm rod is used for a critical span, this rod is used as an extra

reinforcement in compression zone, along with 12mm or 16mm bars. Which is

provided at the intersection of column and beam.

(12mm rods in compression zone, 16 &20 mm rods are placed in tension zone

in beam.)

Stirrups diameter is 8 mm, and they are placed at 200mm c/c & 120 mm c/c

depending on the structural design and length of beam.

Reinforcement consumption in Roof beams



3.3) SLAB

Slabs are designed as 1-way and 2-way slabs.

Concrete required for casting entire slab is 112 cu.m for a plinth area of 10,500 sft.

Reinforcement for slab

Cover blocks are provided at adequate distance.

Cover used for slab is 15mm.

Thickness of slab is 130mm.

Reinforcement bars in slabs used are 8mm and 10 mm at spacing of 150mm,

180mm & 200 mm as per drawing, which differs from slab to slab.

Needle vibrator of 50 mm diameter is used for compaction of concrete in slab.

The level of concrete is checked after pouring the concrete.

During slab casting SOP is followed.

Curing is done for 7 days, method of curing adopted is ponding.



Typical slab layout

Recommendation:

It is better to cast slab in night than in afternoon, since the freshly casted

concrete has chances of getting cracks when it is exposed to sunlight.

Filler slab technique to be followed to reduce the concrete quantity.

Curing should be done properly for 7 days.



3.4) COLUMNS

Number of columns for basement, stilt and 1st floor=31 each floor.

Number of columns for 2nd to 14th floor =62 each floor.

Various Diameters of Reinforcement used in columns are 32, 25, 20, 16&12mm.

Maximum diameter used in column is 32mm.

Lap length of rod for a column is 50(dia).

Curing for column is done by curing compound POLY CURE-R.

DE shuttering for columns is done after 8 hours.

3.5) BLOCKWORK

Aerocon Blocks are used for the entire structure.

Autoclaved aerated concrete (ACC) blocks. These blocks are light weight, easy to

handle and have high thermal insulation and sound absorption properties.

Aerocon Block

Instructions for using Aerocon blocks:

Unload blocks on a dry level surface raised above ground and cover them to prevent

exposure to rain or severe weather conditions.

Blocks can be easily cut/sawn, drilled, nailed and routed at site using recommended

tools. Cutting of blocks can be done by using handsaw.

Mortar for construction:

Recommended mortar for construction is 1:1:6 (cement, lime, sand) or 1:6 (cement,

sand).

The mortar shall not be spread so much ahead of the actual laying of blocks as it tends

to stiffen and lose its plasticity there by resulting poor adhesion to bond.

Maximum thickness of mortar should be 15mm.

Mortar consistency to be maintained at time of laying block masonry.



Laying of block work:

Do not soak the blocks during laying. All surfaces of blocks are to be moistened, using

wet brush, to prevent absorption of water from mortar. Best way is to dip and remove

the blocks.

For walls above ground floor, provide bed cement mortar 1:8, before starting the first

course of blocks .check the height.

Block sizes are 8 inch and 4 inch, hollow blocks.

Length of block is 60 cm.

Type of bond pattern used is stretcher bond.

Place the marker course of block (1st course) after checking the vertical & horizontal

alignment.

First measure if the given area is to plan as per correct and updated drawings.

The first course in blockwork is most important one. Using the spirit levels, check if

the erected wall is perfect –the surface should be free from undulations and cracks.

All concrete surfaces of beams and columns in contact with blockwork is to be

hacked. Since hacking is not used in our project. In place of hacking flexcrete is been

used.

Using the tape ensure the diagonals are equal.

Use Mesh for every 800mm height (4 layers of blocks) .the mesh used in project is

punching plate. Punching plate is used for only 4” inch block work (100 mm).

For bonding of block work to columns, Band concrete is provided at 1.2 m height

from floor level, wall ties are used to cast into columns at a vertical spacing not greater

than 500mm and is aligned with the horizontal mortar band. This is used for 4”

blockwork (100mm).

Note: For 8 inch walls band concrete and punching plate both are not used. Since the

8inch block itself gives the stability to wall.

Hollow blocks are used to fill the lowest (1st course) with concrete 1:3:6 using 12mm

jelly to give a firm base for chipping to fix skirting.



Punching plate

Mix mortar in proportion of 1:5 on MS sheet using Farma Box for measuring sand

and a measuring can to standardize quantum of water to get a consistent mix.

Mix well for uniformity. Mix mortar in small manageable quantities and use it

within ½ an hour.

Mortar joints shouldn’t be more than 10 mm for both vertical & horizontal joints.

The joints should be neatly pointed using an aluminium straight edge or German

pointing trowel.

Don’t construct more than 1 m in a day.

Don’t place the topmost block under the beam until the immediate upper floor block is

raised up to the beam bottom, less one course.

In the top floor, build the parapet wall and do the water proofing and screed concrete

before placing and packing the last course.

Adjuster course in concrete 1:2:4 should be laid two in courses below the beam and

not above the topmost course.

Use hollow blocks at the location of electrical conduit and raise the conduit along with

the block work.

Dowel blocks to be left for further extension of block masonry.

Continuous horizontal chasing should be avoided. Chase block work using chasing

machines.

Start chasing after 21 days of block work construction.



For tiled surfaces it is a better option to chase after rough plaster is done and cured for

21 days.

All nibs adjacent to columns and less than 200 mm, should be cast in RCC at site using

M20 grade of concrete and curing for 7 days by covering with hessian clothes.

For mortar joints more than 10mm, packing of chasing for pipes, junction box etc.

Should be done in PCC 1:2:4 using 12mm jelly and cured for min 3 days.

Write down the date of work in paint on the block work and monitor the curing

accordingly.

Cure the block work by spraying water on the mortar joints only for at least 7 days.

Fibre Mesh

Cast the cut lintel, sill and chejjas over large openings, place them as end-to-end beam

type.

If bearing cannot the reinforcement be given as required lockset the reinforcement of

lintel into the column for a depth of 4d for cast insitu works.

Check chejjas and sills for toppling effect. If suspect, build counterweight courses for

lintel, sill and chajjas.

Continuous vertical mortar joints should be staggered and vertical movement joints to

be given every 12m.



Blockwork Check Using Plumbob

CARE AFTER BLOCK WORK:

Do not entertain excessive chasing as it disturbs the mortar joints causing

hairline cracks and weakening the work.

Don’t soak the blocks with water while curing. The moisture absorbed by the

blocks will be released subsequently causing volumetric variations and

shrinkage cracks.

The interface between block and concrete is the most critical zone and needs

special care. This is due to incompatibility between two heterogeneous

materials.

Before plastering these zones should be given special treatment.

After 7 days curing of mortar joints drive a nail into the joint to test the

strength of joints at random.



3.5.1) FLEXCRETE (THE BONDING AGENT)

In our project Masseys, no hacking is done, instead of that a chemical called

flexcrete is applied.

The outdated method of hacking concrete surfaces for plaster bonding is an

inefficient, slow and unreliable method.

Modern construction methods specify the use of chemical bonding by polymer

dispersion bonding agents.

It is applied at the junction of block work and RCC work.

Flexcrete is a specially formulated pure acrylic polymer dispersion with

extraordinary adhesion and compatibility with concrete, plaster and masonry

surfaces.

Flexcrete compound (Along with mortar (1:1) on column)



ADVANTAGES OF FLEXCRETE:

No need for hacking with Flexcrete.

Flexcrete is quick and easy to apply; provides exceptional bond strength and

has a very long working time. And it is cheaper than hacking!

Long working time means plaster can be applied up to 3 days after the bond

coat without compromising on bond. Other bonding agents require plaster to

be applied before they lose tackiness. Thus work scheduling flexibility is

greatly increased.

Bonds new plaster/concrete, new /old concrete, new plaster/masonry.

Product specification:

Specific gravity : 1.05 kg/lt

Application : brush

Solid content : 45+2%

Expiry time : 6 months from manufacturing.



3.5.2) LINTELS AND BAND CONCRETE

Lintels are erected from 7ft above floor level.

Concrete Grade used in lintels is M30.

But aggregates size is 12 mm, we are not using 20 mm aggregates.

Lintels are Precasted and they are directly placed in that particular location.

Reinforcement bars used are 12mm, 8mm stirrups are placed at uniform placing.

Curing is done for 3 days.

Recommendation:

During erection of Lintel, it is getting difficult to cast in its position because of heavy

weight, since crane services can’t be utilised inside in the room, its is better to cast

lintel in cast-insitu

Reinforcement for lintel



Band Concrete

It is casted for every 1.2 metres from floor level, to a 4 inch wall block work.

Thickness of band concrete is 100 mm.

Main purpose of this concrete is to get more strength to blockwork and reduce cracks.

2 Reinforcement Bars of 12mm diameter is used for band concrete and they are

penetrated through some portion of column.

M30 grade concrete is used with 12mm aggregates.

It is not used for 8 inch Block work.

Band concrete Lintel



3.6) PLASTERING

All surfaces for plastering should be wet to prevent absorption of water from plaster.

Mix shall be generally CM (cement mortar) 1:4 for ceiling and 1:6 for wall plastering.

The CM mix should be used within ½ to 1 hour of mix.

All cut-outs such as fan, junction box, electrical box and skirting line should be finished

to perfection.

The blockwork should have been cured for 7 days and dry before plastering is started.

Button mark the surface to be plastered keeping the bull minimum. 12mm plaster is

desired thickness. Distance of button marks should be within an aluminium edge

length.

Plastering mesh should be 8 inch wide and fixed rigidly before plastering on the

junction between concrete and masonry surface with steel nails. The strip has to be

plastered and cured for min of 3 days before entire wall is plastered.

If thickness exceeds 15 mm, then plastering is done in 2 coats.

The first layer applied should be cured for a day before applying next coat.

In the project, for ceiling – putty finish, bathroom – cement plaster and for other

rooms gypsum plastering is been used.

For internal walls gypsum coating, followed by putty, primer and finally emulsion is

used.

Quantity estimation:

As per BOQ, 15mm thick internal plastering with gypsum plaster for Entire floor

required is 26,084 sq.ft

12mm tk. Ceiling Plastering in C.M 1:3 – for a floor required is 8,254.45 sq.ft.

Advantages of Gypsum Plastering:

No Curing is required.

Room will be cool.

Gives an excellent finishing to surface.

Cracks formation probability is less.

Gives aesthetic appearance to the surface.

Plastering work with gypsum



VANS GYPSUM :( Used in Masseys Site)

It is a pure gypsum based plaster suitable for most internal and partition surfaces

including brick, block and concrete. It consists essentially of pure gypsum hemihydrate

formulated with special additives to control application and setting characteristics. It

contains pure gypsum in natural form, eliminated from all impurities.

Advantages of using VANS GYPLAST:

It gives plaster an unmatched workability because of its smoothness, coverage

and ease of application.

When dried it provides a super white, smooth and fine finish (excellent strength

on drying).

Thermal resistance & fungus free.

Lightweight.

Fire resistant.

Humidity resistant.

High coverage up to 92sq.m/t.

Enhanced light reflection

imparting true colour one.

Compatible with any type of

paint.

Thickness can go up to 32mm.

6 months shelf life.

Mix ratio-1:1 water & gypsum by

volume.

Crack free.

No powdering.

Gives cool atmosphere inside the

room.

Parameters Units

Dry bulk density 667-695 kg/m3

Wet bulk density 1.32-1.46gm/cm3

Initial setting time 14-18 min

Final setting time 24-26 min

Compressive strength(24 hours) 43.8 kgf/cm2

Compressive strength (48 hours ) 44.12 kgf/cm2

Approx. coverage 87-92 m2/t



Inference and Recommendations:

For plastering one room, it is taking 2 days of time, to complete the entire flat it is

taking around 10 days to complete work, which can be improved.

Out of 10 bags of gypsum, 2-3 bags of gypsum is going as wastage, there is more

wastage than required, which should be controlled.

Proper supervision for plastering work is not there, so there are chances for improper

work and errors in finishing.

Mixing of gypsum and water is not as per ratio.

Recommendation

During my interaction with labour, they said they are going to use gypsum plaster,

putty finish, primer and emulsion paint for internal walls of bedrooms and hall.

Since gypsum plaster itself is giving smooth finish to surface, putty finish is not

required, so that cost and time can be saved.



3.7) FLOORING

Vitrified tiles are used for the project.

Kajaria company tiles are being used.

The tiles shall be ordered in sizes as determined by site dimensions to avoid

cutting at site.

The floor drawing is given by the Architects (Naksha Consultants) based on the

drawing, they manufacture the tiles according to the size prescribed in drawing.

The drawing is useful to ensure from where to start the tiles.

The material received at site shall be checked for the following defects prior to

acceptance.

Tiles of same type but with distinctly different color or texture shall be

rejected outright.

Tiles shall be free from holes, seams, shakes, pockets, stains and other

effects and shall be of uniform color and texture.

Dimensional tolerances shall be restricted to

Length + 0.5mm Width + 0.5mm

Aries + 0.5mm Plane + 1 / 500

Ensure that the site is cleaned, taking care to remove any loose concrete, mortar

or other substances

All chasing for the concealed piping, and electrical conduiting etc. shall be

carried out before commencement of work

Make bull mark levels according to architectural specifications

Design mix of Cement Mortar (1:6 or 1:8) to be followed.

The thickness of mortar allowed is 25 mm from floor level.

Ensure that the tiles to be laid are matched, numbered and available in the

required number for laying on the site

Tiles are dry matched in the yard. They are then cut to the exact size required,

and numbered in the sequence and are laid at site in exactly the same order.

As per drawing, work should be started by taking right angles for existing walls.

Laying starts as per the previously numbered tiles

The surface on which tile is to be laid is watered. A bed of mortar is placed on

the floor, and tiles are put into position with white cement slurry.

Levelling is done with an aluminium straight edge and rubber hammer.

If there is any slope, it has to be decided in the bull itself.

Joint filler should make a joint filling material as per colour of the tiles



Putty blade is used to rake all joints and fill the joint material neatly as the joints

will be paper joints.

For fixing tiles to wall, suitable stainless steel mechanical anchors shall be used.

Cure all tiling works and joint filling works for 3 days.

After work is complete, ensure that it is covered with plastic sheet and Plaster

of Paris.

SKIRTING

10 mm tiles are used for skirting, and the height of the tile is 100 mm.

Skirting is chamfered at the edge to 4 mm. and fixed so that after fixing the tile

4 mm of straight edge and 4 mm chamfered edge is seen outside. The skirting

goes into the plaster by about 2 mm.

Check the right angle that the skirting makes with the floor tile.

Step-1) Marking on the wall (level check) from floor level

Step-2) Button Marking



Step-3) Mortar preparation

Step-4) Finishing Tile works

Finishing tile work



Recommendations:

The tiles laying is not done as per SOP of Casa Grande Company.

They are laying mortar thickness of 50 mm, which is not recommendable.

The allowable thickness is 25 mm.

Because of 50mm thickness mortar, the problems encountered are...

Wastage of cement and sand quantity.

Cost overruns

Time taking.

Hollow sound is caused when walked, since there are more voids in the mortar

thickness, chance of sinking the tiles.

If thickness is more, then it is better to do concreting of M10 grade (screed concrete)

instead of mortar for more stability.



3.8) FORMWORK ERECTION (COLUMN)

Timber formwork is used.

Plywood thickness 25mm.

Steps in erecting column formwork

Check the steel reinforcement before starting formwork.

Construct a starter for column at base level which is of 100 mm depth around

the reinforcement bars, by taking the cover for column as 40 mm.

Position formwork from predetermined grids.

Plumb formwork in both the ways and support using adjustable steel props.

Propping angle should be 45 degrees to floor.

The formwork bearers directly supports formwork sheeting. The formwork

bearers consists of squared timbers.

Formwork ties :

Tieing the two form-work faces to each other by formwork ties. It is done by

guiding it through boreholes in the formwork sheeting and tightening it by

twisting.

Brace the formwork for more support to the floor.

Curing for shear wall by using curing compound



Shuttering for columns

INSPECTION OF FORMWORK: (Methodology adopted in Masseys site)

Checking the shuttering work for surface cleanliness, water tightness.

Checking for plumb horizontally & vertically using 1m/2m spirit level to formwork

at various points.

Spirit level

Checking of diagonals using a measuring tape.

5) VARIOUS DEPARTMENTS IN PROJECT

1. Stores department.

2. Quality department.

3. Safety department.

4. Execution department.

5. Planning department.

6. Marketing / sales department.



5.1) STORES DEPARTMENT

Number of employees – 2.

Role of stores department:

Issue of purchase order.

Procedure:

Responsible engineers will give the requirement of various quantities to store

manager.

The store manager in site will create manual indent.

He sends the indent to the office store in charge.

Then the head of stores department will create indent by using BSF software and by

Coordination with Quantity Estimation Department.

The indent goes to purchase department.

The purchase department will look for vendors and make purchase order.

After the cycle procedure, the required quantity will come to stores department of

respective site.

The store manager will check the quantity received and the remaining quantity to be

received.

He checks the quality and quantity arrived and note down the time, date and vehicle

number and make entry.

He is responsible for storing items till utilised.



Cement storage

Cement, steel, aggregates will get to site after 1 week from purchase order.

1 vehicle has capacity of transporting 300 bags of cement at 1 stretch.

So there by taking that 7 days also into consideration, without affecting delay of

project, they are issuing purchase order, when the quantity is reaching to reorder

level. (I.e. 7 days before consumption)

Cement, aggregates are stored for 1 month.



Inference and Recommendations:

From the store in charge various material rates and their quantities came to know.

There is proper listing of materials in project about their consumption.

Materials are stored properly in proper alignment.

Material unit Cost(in

rupees) Cement Kg 6

Gypsum

plaster

Kg 12

Aerocon

blocks Inches 72-8” block

36-4”block

Steel Kg 38

Recommendations:

Since there is very less space in the project, storage of materials is getting big

hectic job for store in charge, and JCB is also getting difficult to move. So JIT

(Just in Time) technique should be followed, the uses of this technique is

clearly illustrated in separate recommendations page (please refer that).

Issue slips should be issued by store in charge to concerned responsible

engineer.

There should be extra or spare materials available in site for sudden

requirement.

Metric tapes are shortage, problem for engineers to inspect.

Additional Safety equipment is not available in site. Helmets, safety shoes etc.

are in limited number.



5.2) MARKETING DEPARTMENT

Number of employees =80 for entire Casa Grande company.

Role of marketing department:

Stalls in corporate sector.

Promotional activities.

Advertisements in local and national newspapers.

Pamphlets.

Banners in ongoing construction project.

When I interacted with the marketing executive, they said they are having least

pressure because the company Casa Grande is a well-known company in Chennai

and 9 out of 10 people knew about the reputation of the company.

There are Facebook pages for company, having more that 1 million likes, the page

mainly focusses on the publicity activities and details of every project by staying in

touch with public.

So no more marketing strategies are required to go through the public.

INFERENCE:

In the project of Masseys so far 66 % of sales took place (61/91) till the date.

The sale is pre sale that shows the confidence on casa Grande Company by public.

For pre-sale there is 1% discount on total flat cost.

The company is having tie up with banks like HDFC and other reputed banks in

Chennai.

In addition to this there is recovery department in the company, the main motive or

objective of the company is not losing the customers.

If the customer feels that they can’t afford the amount, this department will show the

other project which is as per the budget and explains them the details and amenities.

The cost of Masseys flat varies from 98.5L -99.61L for double bedroom and 1.22C -

1.35 C for triple bedroom flats.

As most of the customers are preferring for upper floor flats for better scenery of sea

view, there is more demand for higher floor flats and rates are slightly higher for

higher floor flats compared to lower floors.



By using Buddy Neighbour Scheme, which is a good marketing strategy followed

in Casa Grande Company, made the bookings faster.

RECOMMENDATION:

Since many customers are visiting the site and interacting with marketing department

about the project, the marketing department is unaware of the technical details about

project, they are calling to the engineers who are busy in some other work, to know

the technical details.

So the customers are feeling little uncomfortable for the delay .so I recommend in

place of MBA candidates in marketing department , there should be techno-

management employees to sort out the issue.

Advertising through television should be implemented.

Shortage of marketing employees in Masseys site.

Temporary lift should be erected in site, for the convenience of customers to avoid

5.3) QUALITY DEPARTMENT

Number of employees in site = 3.

Role of Quality Department:

Responsible for various quality issues in the project like honey combing of concrete,

bulging of column, level of roof beam etc. .

The various checks are carried out by the department using quality checklist.

They write various issues in the project on the notice board, those are to be sought

out by the respective department.

At least one of them are to be in concreting in slabs , beams ,columns ( RCC works )

, they have to sought out the issue immediately by taking them to responsible

engineer.

Testing the cubes and finding the compressive strength and slump value and

checking whether the deshuttering work is to be carry or not.

Since by rectifying the issue on spot, there won’t be any quality issues further.

Checking the works whether they are done as per standard operating procedure

(SOP) or not.

They are finding the latest advanced methodologies that can be implemented in site

to minimize the quality issues, which is a good sign.

QUALITY ISSUES

HONEY COMBING

Honeycombs are hollow spaces and cavities left in concrete mass on surface or

inside the concrete mass where concrete could not reach. These look like honey bees

nest.

Honeycombs which are on sides are visible to naked eyes and can be detected easily

as soon shuttering is removed. Honey combs which are inside mass of concrete can

only be detected by advanced techniques like ultrasonic testing etc.

Reasons for Honey Combing:

Improper vibration during concrete.

Less cover to reinforcement bars.



Use of very stiff concrete (this can be avoided by controlling water as per slump test)

Places like junction of beam to beam to column and to one or more beams are the

typical spots where honey combs are observed. This is due to jumbling of

reinforcement of beams and column rods at one place; special attention is required at

such place during concreting and vibrating.

Presence of more percentage of bigger size of aggregate in concrete also prevents

concrete to fill narrow spaces between the reinforcement rods.

Placing too much concrete in one area at a time can result in incomplete

consolidation, causing a honey comb.



Effects of honey combing:

1) Honeycombs reduces the load bearing capacity of the structure.

2) Corrosion problem

Water finds an easy way to reinforcement rods and rusting and corrosion starts.

Corrosion is a process which continues through reinforcement rods even in good

concrete, this result in loosing grip between rods and concrete, which is very

dangerous to safety and life of concrete structures.

R.C.C. structures have failed with in 20 or 30 years of their construction which is

less than half their projected life. Especially no risk should be taken in case of

columns, Machine foundations, Rafts, Beams etc., where breaking and recasting is

the only best way.

Honey combing

Remedies for Honeycombs in Concrete

In case of honey combs on surface pressure grouting with cement based chemicals

which are non-shrinkable can be adopted after taking opinion of the designer and

acting as per his advice.

At places of junction of columns and beams concrete with strictly 20mm and down

aggregates should be used with slightly more water and cement to avoid

honeycombs.

Taping with wooden hammer the sides of shuttering from outs side during

concreting and vibrating will help minimizing honeycombs to a great extent in

case of columns and beams.



Use of thinner needle say 25mm or less with vibrator at intricate places of

concreting will also help in reducing honey combs.

Plastic Shrinkage:

Plastic shrinkage occurs when a high rate of water evaporates from the concrete

surface and is affected by temperature, humidity, velocity and temperature of

concrete. While it is not possible to control the temperature or humidity at the

location where we are pouring concrete, we can prevent shrinkage by:

Remedies for shrinkage cracks:

Dampening the surface

Erecting windbreaks to reduce wind velocity.

Minimizing placing and finishing time.

Curing as soon as possible after finishing Using membrane curing compound,

curing paper, and wet burlap, sand.

Quality issues



Scaling problem

Scaling generally starts with a small area but expands as the concrete surface begins to

flake or peel away.

Scaling is caused by:

Faulty concrete finishing or workmanship.

Water seeping into porous, non-air entrained concrete that is exposed to freezing and

thawing cycles.

Scaling can be prevented by:

Specifying a proper mix design for exterior flat work which should be low slump and

air entrained.

Delaying finishing operations until all standing water has evaporated or been removed.

Once concreting has been finished, continue proper concrete care tips by avoiding the

use of salt or other harsh chemicals.

Some other quality issues occurred in site are beam and column bulging, dampness

on surface.



Inference:

The quality issues are almost rectified in time itself, there is no delay in rectifying out

the issues.

There is training for employees in various quality issues for once in a month.

Curing is done properly.

Many of the works are going as per SOP.

Various tests done for concrete in site Masseys:

COMPRESSION TEST:

A total of 9 cubes were prepared for testing which are of 15x15x15 cm.

3 cubes are tested at 3 days, 7 days and 28 days.

Average of the values from 3 cubes are considered as characteristic strength of

concrete.

In our site we achieved 105 -110 % strength in 28 days.

Cubes

SIEVE ANALYSIS:

Sieve analysis test is used for M-sand, many a times resulting the sand is good for

construction. Various sizes of sieves used are 4.75, 2.36, 1.18, 0.6, 0.3, 0.15 mm.

SLUMP TEST

USING SLUMP CONE:

Done to determine workability of concrete.

A slump of cone of 30 cm height and bottom dia 20 cm, top dia 10 cm is used.

Concrete is poured in 3 layers by proper compacting.

Later the cone is removed.

Inference:

The concrete is true slump having a slump value of 120 mm.

Slump cone

Recommendation:

There should be training for labourers also specially in concreting works.

Daily inspection for works should be strictly followed.

Issues in quality are to be noted immediately to the higher official for proper remedy.

During plastering work skilled labour is required.

SOP (Standard Operating Procedure) should be strictly followed during working.

Honey combing, dampness etc. issues are to be taken special care.

Inferences and Recommendations

In the project, safety is as per OSHA standards, most of the safety norms are

followed in site.

Workers are using PFAS, Helmets, Gumboots, safety jackets, eye protectors while

working.

Safety nets are erected where as required, which has the capacity of 100 kgs, debris

in safety nets are cleared for every alternate days.

Barricades, fencing, fire extinguishers, sign boards are present in the site.

Temporary handrails are erected for stair case.

Monthly induction training for new workers is implemented and health check-up is

done for every 6months.

Some of the staff from Casa Grande & contractor side are also not following safety.

Recommendations:

During night work, lighting is not adequate, chances of danger is risk is more.

Some of the areas are not covered with safety nets.

Due to additional work like BSF entries of time office and security room monitoring

to the employees of safety department, they are not able to spend their time in

monitoring the safety norms in site.so it is recommended to implement 100% safety

supervision to employees by employing additional worker to assign other duties

like BSF entries and security room supervision.

Although the labour are provided with good safety equipment, they are not using to

full extent, so a video presentation about the accidents that occur while working

should be demonstrated to employees.

Rebar bars should be provided with rebar caps for avoiding injury.

Issuing of cards system, like the worker who is violates the safety norms should be

awarded with yellow cards, if get three cards in same month, then he should be

warned and given red card, in six months if he receive 3 red cards then he should be

terminated from job.

Rewards should be given to workers, who is following 100% safety.

Additional safety equipment should be readily available for labours and employees.

SAFETY FIRST ANYTHING NEXT



5.5) EXECUTION DEPARTMENT

Number of employees=4.

Role of the Department:

Inspects the reinforcement work, concreting work, blockwork, plastering, tiling,

painting etc. Which are executed by labour.

Their role is to look whether the work is going good or not. They coordinate with the

staff of contractor and are responsible for perfect execution of work.

If any issue happened in site, they convey that to their higher authority.

They act as a mediator between labour and higher official.

They do modifications to drawings if any client wants special requirements.

They coordinate with various departments like plumbing, electrical, carpenters etc.

for carrying concreting in slab.

Inspects every work carried out in site and sends DPR (Daily progress Report) to

higher authority.

Recommendations

Employees should be trained well to execute the specialised work like plastering,

tiling.

Communication gap between contractor employees and company employees is there,

so proper coordination between them should be there to do a particular task, so it is

recommended that they should assemble together and discuss about the methodology

adopted to carry out the work.

Since there is communication between contractor (sky world) and Casa Grande, the

procedure which contractor is following is not as per SOP of Casa Grande in some

cases. So the execution department is unware of the procedure and lacking of

technical skills, so proper training should be given to employees.

Series1



Analysis from Graphs

The first floor roof slab took 47 days to complete, which consumed more days than

other floor slabs because, the first floor beams are PT (Post Tensioned) beams

which are complicated and unique . There are other 62 columns erected from the 1st

floor, which are floating columns that means they have no foundation on ground

level.

The first floor roof slab is heart of the structure, Due to the complexity of

design it took extra days to complete the work.

Apart from this, almost every slab is completed for an interval of 12-13 days.

Column completion days, the first floor columns took more days than other, the

reason as stated above.

Due to some other issues, which stated in delays of project the column completion

days got varied.



5.6) PLANNING DEPARTMENT

No of employees: 2

Planning engineer:

A planning engineer works with a site manager to develop suitable construction

Methods and sequences for a project.

Job description:

Planning engineers determine and develop the most suitable and economically viable

Construction and engineering methods for projects. They are involved throughout the

stages, and are present on site during the build to oversee procedures. It is the respons

ibility of the planning engineer to estimate a timescale for a project and to ensure that

The outlined deadlines are met. They work closely with site managers and

Other Engineers to ensure a project runs on schedule and that material supplies are

Sufficient.

Planning Engineer Roles and Responsibilities:

Prepare and update project schedule based on the contract.

Set work program and target milestones for each phase based on the project

Plan.

Monitor critical activities based on the project schedule and advise project

management.

Prepares and submit updated work program and cash flow curve showing

Actual progress and identify areas of weakness and establishes means and meth

ods for recovery, if any, as well as new critical activities.

Monitor day to day work progress and prepare the weekly and monthly

Program and report.

Maintain and record update of site work progress obtained from Project

Manager.

Prepares monthly report reflecting work progress summary.

Report to the Project Manager about the current work progress and make comp

arison between plan and actual progress and study impact of alternative



Approaches to work.

Participate in project meetings and discussions with the Client as required.

Assists in preparing work program, cash flow and manpower histogram for

Tenders.

Performs other duties and responsibilities as may be assigned from time to time

& Prepares Daily Progress Report.

Recommendations:

Presently in site, the planning engineers are using EXCEL for planning as a tool fo

r tracking. But by EXCEL proper tracking is not possible. So by using PRIMAVE

RA or MSP tracking is possible in a better way.

So the employees should be trained in primavera or MSP for better results.

6) DELAYS IN MASSEYS PROJECT A project Team comes together to create a unique development on a particular site

under circumstances that will never be repeated. They are very complex, requiring

the co-ordination of permissions, people, goods, plant and materials and construction

can begin despite many ‘unknown’ matters such as incomplete design information,

uncertain site conditions, Suppliers and so on. As a consequence delays are common.

Some of the Delays in MASSEYS project which encountered are ….

1) Delay in drawings

Delay in drawings from consultant for basement and stilt floor, which are typical and

complicated delayed. Many a time’s modifications are done to the drawings as per

site conditions, which led to the delay of work.

2) Poor safety Practices in site.

Since there is no safety net erected in site , some of the concrete while pumping

during casting slab gone to the surrounding apartment due to excess pressure in

pumping plant, due to this objections made by surrounding people delayed the work

for 1 week.

3) Pile Foundation:

There are almost 114 piles were used in the site, pile depth is 30 meters , while

casting a pile due to Vibrations and sound , objections from local people raised,

which led to the delay of almost 3 months.

4) Local Issues:

Some of the miscellaneous issues like general elections, followed by some of the

holidays led to delay in project.

5) Weather conditions:

Since the site is situated in coastal region near beach, heavy breeze and winds spoiled

the work, like… during blockwork checking using plumbob, due to continuous winds

they were unable to erect the blockwork, because plumbob is continuously moving

and giving negative correction. They have waited for long time till the wind to stop.

Although there is less temperature in Chennai than other places, the humidity that

caused Labour to dehydrate and the efficiency of work got reduced.

Untimely rains (cyclone) in Chennai that led to delay in construction work several

times in months of December as well as in May.



6) Uniqueness of Project:

As every project is unique in nature, the Masseys project is much more unique, since

there is very less repetitive work involved.

The pile foundation work.

Post tensioning for slabs and beams of 1st floor, stilt & basement floor.

Extra 31 floating columns on 1st floor roof, which are erected from PT beams of

1st floor.

Additional complicated design and modifications for stilt floor made it much

more complicated and unique.

7) Poor or unrealistic schedule:

Unrealistic schedule from planning department or improper coordination between site

executives and planning department led to the delays in project.

Like for example, the planning department prepares the schedule without considering

various factors like weather, labour problems, local issues which are variant to the site,

will make the delays.

8) Lack of information and poor communication:

Lack of information and poor communication between the contractor’s side and

company’s side led to the delay of project. Meetings between the contractor and

company is not frequent.

9) Labour productivity:

Labour absenteeism, there is no control whether how much labour turned out, labour

stress because of continuous work, labour skill etc, Effected the productivity of work.





6.1) MEASURES TO BE TAKEN TO OVERCOME DELAYS

Additional resources of manpower, plant and materials directly employed

or subcontracted.

Revised methodologies including off-site prefabrication, extra scaffolding, and

temporary weatherproofing and so on.

Proposals for phased completion.

Increasing working hours on and off site, including weekends, holidays, night

working and shift working.

Additional supervision.

Changes to the design or specification .

Reduction in scope (for example transferring work to a separate post-contract

agreement for occupational works).

Low technical and managerial skills of contractors are the problems that faced by

contractors which might cause construction delays. Therefore, contractors should

organize some training programs for their workers in order to update their

knowledge and improve their management skill.

Frequent progress meeting.

Use up-to-date technology utilization.

Use proper and modern construction.

Proper emphasis on past experience.

Effective strategic planning.

Clear information and communication channels.

Complete and proper design at the right time.

Site management and supervision.

Collaborative working in construction.

Frequent coordination between the parties involved.

Compressing construction durations.

Proper project planning and scheduling.

Proper material procurement.

Use appropriate construction methods.

Accurate initial cost estimates.

Preparing the checklists of safety and quality by considering all the measures.

http://www.designingbuildings.co.uk/wiki/Specification



6.2) METHODOLOGY ADOPTED TO OVERCOME DELAYS

Ranking of delays

The causes, effects and minimisation of construction delays were ranked by using

relative important index.

The data analysis is determined to establish the relative importance of various

factors that contribute to causes, effects, and minimization if construction delays.

Analysis of data consists of the following:

1) Calculating the Relative Importance Index (RII)

2) Ranking of factors in each category based on the Relative Importance Index (RII)

RII= (∑W/AxN) Where,

RII is the Relative Importance Index,

W = weighting given to each factor by the respondents (ranging from 1 to 5),

A = highest weight (i.e. 5), N = total number of respondents.

In this way the most important cause for the delay is considered and necessary

planning is done to avoid that cause, so that the project will complete in time.



7) RECOMMENDATIONS

7.1) VARIOUS COST REDUCTION TECHNIQUES IN HIGH RISE

BUILDINGS

A) FILLER SLAB TECHNIQUE

In a conventional RCC slab which is used from many years as a ritual practice

consuming more and more resources by employing more labour and material cost.

Due to this unnecessary cost for additional reinforcement due to added load of

concrete is consuming most of the part in project cost.

ALTERNATIVE TO RCC SLAB

Conventional RCC slab can be replaced by low cost and light weight filler material,

which will reduce the dead load and cost of the slab by 22-28% (40% less steel is

used and 30 % less concrete)

PRINCIPLE OF FILLER SLAB

The filler slab is based on the principle that for roofs which are simply supported, the

upper part of slab is subjected to compressive forces and lower part of slab is

subjected to tensile forces. Concrete is good in compression and weak in tension,

thus the lower part of slab doesn’t need any concrete except for holding steel

reinforcements together. Thus by replacing the concrete in tension zone with any

filler material gives the same characteristics of conventional concrete.



Concrete cross-section

Filler material in tension zone.

MECHANISM OF FILLER SLAB

The filler slab is a mechanism to replace concrete in tension zone. The filler material

thus is not a structural part of slab, by reducing the quantity and weight of material,

the roof becomes less expensive, yet retains the strength of conventional slab. The

most popular type of filling material is roofing tile. Mangalore tiles are placed

between steel ribs and concrete is poured into gap to make filler slab. The structure

requires less steel and cement and it is also a good insulator.

Tiles alignment in filler slab

FILLER MATERIAL SELECTION

Filler material should be inert in nature. It shouldn’t react with concrete or

steel in RCC slab construction.

Filler material should be light in weight, so that overall weight of slab reduces.

Filler material texture should match with desired ceiling finish requirements.

Filler material should be of a size, cross section and thickness which can be

accommodated within spacing of reinforcement and cross section of slab.

Filler material absorption should be checked, since it may absorb the water

from concrete.



INSTALLATION OF FILLER MATERIAL

Filler materials shouldn’t be installed at shear zone.

Clear distance of 150mm from end supports in all directions.

Gap of about 75mm between each unit of filler material.

Normal spacing of filler tiles

EFFICIENCY OF FILLER SLAB

Conventional Tests By Different Institutions And Laboratories Has Proved The Load

Bearing Capacity Of Filler Slab And Found It No Less In Performance From

Conventional RCC Slab. Since Filler Tiles Are Firmly Bonded To And Covered By

The Concrete, It Doesn’t Collapse Under The Impact.

BENEFITS

The Savings On Cost Can Be Up To 22-28 %. But Designing A Filler Slab Requires

A Structural Engineer To Determine The Spacing Between Reinforcement Bars.



THERMAL INSULATION

The Air Pocket Formed By Contours Of Tiles Makes An Excellent Thermal

Insulation Layer. The Design Integrity Of Filler Slab Involves Careful Planning

Taking Into Account The Negative Zones And Reinforcement Areas.

PATTERENED CEILINGS

Filler slabs provide aesthetically pleasing patterned ceilings. In most houses the filler

material is left open without plastering to form aesthetic design.

B) Lintels and Chajjas

The Traditional RCC Lintels Which Are Costly Can Be Replaced By Brick Arches

For Small Spans And Save Construction Cost Up to 30-40% Over The Traditional

Method Of Construction. Arches are Economical and Aesthetic.

.



Building Cost:

Building material cost: 65 to 70 %

Labour cost: 65 to 70 %.

Cost of reduction is achieved by selection of more efficient material or by an

improved design.

C) Doors and windows:

It is suggested not to use wood for doors and windows and in its place concrete or

steel section frames shall be used for achieving saving in cost up to 30 to 40%..By

adopting brick jelly work and precast components effective ventilation could be

provided to the building and also the construction cost could be saved up to 50% over

the window components.

D) Amalgamating services:

Locating bathrooms kitchens and laundry’s etc. adjacent or above each other, can

reduce the cost of providing services (particularly plumbing) as the length of

concealed pipe work and conduit is reduced. Similarly amalgamating several services

in the same trench or duct can reduce costs...

E) Speed of Construction:

A building construction method that is faster not only utilises labour more efficiently

but also reduces the daily on-site costs such as building foreman, fencing,

scaffolding, site services, insurances etc.

F) Prefabrication Fabricating:

Items in a factory is always faster and cheaper than on site. This is because there is

not always a good supply of shelter, materials, specialised machinery and labour on

site. The extent of prefabrication can range from individual components, right up to a

totally prefabricated home.



MATERIAL SELECTION CRITERIA

Conclusion

However it is necessary that good planning and design methods shall be adopted by

utilizing the services of an experienced engineer or an architect for supervising the

work, thereby achieving overall cost effectiveness to the extent of 25% in actual

practice.



7.2) JIT TECHNIQUE

Just in time (JIT) is an inventory management system, used to manage the stock that

is kept in storage. It involves receiving goods from suppliers as and when they are

required, rather than carrying a large inventory at once.

Advantages

Lower Warehouse Costs:

Storing excess inventory can cost a lot of money, and reducing the amount of

inventory you keep on hand can reduce your carrying costs as well. Companies that

implement the just-in-time inventory model may be able to reduce the number of

warehouses they maintain, or even allow them to eliminate those warehouses

altogether.

Better Supply Chain Management:

The just-in-time inventory model can also help companies be more efficient and

competitive in the way they handle their supply chains.

A more efficient supply chain can provide lower costs throughout the construction

process, and those lower costs can then be passed on to the customer. Those lower



costs can make the company's products more affordable, and help the company gain a

larger market share and stay ahead of its competitors.

Less Waste:

When companies use the traditional method of inventory management and control,

they can end up with pallets of unused items that simply go to waste. The company

many need to slash prices on that unsold inventory just to get rid of it. The just-in-

time inventory model reduces this waste and helps the company respond more

quickly to what its customers need.

Smaller investments: JIT inventory management is ideal for smaller companies that

don’t have the funds available to purchase huge amounts of stock at once. Ordering

stock as and when it’s needed helps to maintain a healthy cash flow.

All of these advantages will save the company money.

Explaining With an Example:

Suppose if you have a sum of 1 lakh rupees, if you spend the entire amount in buying

Aggregates, cement and other materials which is necessary for 1 month , if any delay

occurs or some extra budget needed for other items ,to carry out the work money will

be on hold . So by using JIT technique, the day on which concreting takes place, on

that day itself if we get raw materials, money won’t get hold for much time, and

instead they can be used for other purposes.

Security for items not required:

For larger inventory there are chances for theft of raw materials, so CCTV Supervision

or any other supervisor is employed to check the materials, which requires additional

cost, in case of JIT technique, that problem won’t be there since the material will be

arrived at just on time. Supervision cost will be reduced.

Quality of raw materials:

Since we are ordering the materials just on time, the damage of the material will be

very very less compared to conventional method of storage.

Cement tends to lose its strength as the days are passing i.e. from date of manufacturing

to usage of cement, so immediate usage of cement gives extra strength to concrete, this

is only possible by JIT technique.

https://www.babington.co.uk/cashflow-forecasting-webinar/



Disadvantages of just in time inventory management:

Risk of running out of stock: By not carrying much stock, it is imperative to have

the correct procedures in place to ensure stock can become readily available, and

quickly. To do this, it is better to have a good relationship with your supplier(s). It is

needed to form an exclusive agreement with suppliers that specifies supplying

goods within a certain time frame, prioritising the company. JIT means extremely

reliant on the consistency of supply chain. There is chance that supplier struggles
