Project Communication

2.1 INTRODUCTION

The performance of any project can be evaluated from the daily reports

and other correspondence, that it maintains. Well framed reporting systems

serve as an effective tool of information, which if compiled, documented and

analyzed, provides a record on the project for 'future reference.

The management can adopt certain systems to control the progress of a

project. The documentation required, acts as an effective tool of control over

the overall performance of every individual, from the engineer, the site staff,

consultants to the architect, involved in these systems. The procedure for

documentation of the in-house and outside correspondence, at different stages

of work, is standardized, In this chapter we discuss some of these procedures

and the methods of correspondence, that facilitate the working and help gain

overall control over the staff and systems.

2.2 PROJECT COMMUNICATION WITH HEAD QUARTER

- All correspondence is related to the progress of the site work.

- Correspondence from the site to Head Office is an important

communication channel for the senior management.

3. LAYOUT

Good site layout is important to improve productivity. You need to arrange

your construction site in such a way as to make it function as efficiently as possible.

With bad layout, time and materials are wasted through double handling.

Transport and handling of materials always cost money. Every time you more a stack

of bricks around your site, the real cost to you increases. One of the reasons for slow

progress and high cost of construction projects is the lack of site planning, including

poor site layout.


[Type text]

The layout plan of the site will depend upon two main factors: the methods

and sequence of operations to be employed in carrying out he work, and the space

available. The methods and sequence will have been considered at the time that the

estimate and tender were prepared. When the contract is awarded, you should take

another careful look at these ideas before preparing a detailed site layout plan.

These plans must be prepared in advance and they must be prepared by

someone with good planning skills and experience. It is often easier to save money

through planning than by raising site productivity, but these savings can only be

obtained if you take enough time to think about all the possible alternatives before

deciding on how to layout the site.

Contract documents: The contract document for the proposed project is voluminous and contains the

following documents:

a) Notice inviting tender. b) Information and instructions to tenderer. c) General conditions of contract. d) Special conditions of contract. e) Schedule of quantitative and cost.

f) Tender drawings. g) Specification for works.

h) Forms for bank guarantee in respect of earnest money. i) Performance guarantee.

j) Mobilization advance etc. k) Hypothecation deeds for construction equipment.

l) Tender related correspondence and the letter of award/acceptance.


[Type text]

While the provisions existing in various clauses of the different sections of the

document have their own independent intent, meaning and interpretation, a proper

management of the contract is set up for interpretation of individual clauses in

harmony with others, so that it is in the interest of efficient and timely execution of

work. This is applicable both to the client and the contractor.

For the proposed work, work below ground is allotted as cost plus percentage rate

and for work above ground it is allotted as item rate contract. It is also assumed that

the contract drawn up is fair and equitable and takes into account requirements of

client and possible difficulties that may be experienced by the contractor in his

operations.

SITE CLEARANCE Before setting up of enabling works, it is necessary to make the site clear from various

aspects such as: -

Any stockpile of irrelevant material laid on site.

Any machinery, equipment or vehicle not related to proposed site work.

Plant, vegetation or crops of reasonable height in the proposed site area.

Depending upon the direction of wind mentioned, provision of temporary unit

such as barrier is made on the west side of the bridge to avoid accumulation of

unnecessary dust & rubbish materials.

Removal of small pebbles, sharp edge stones, loose soil material from the

surface of site area.

Demolition of any previous temporary structure present on the site.

CONSTRUCTING INFRASTRUCTURAL FACILITIES

The following infrastructure facilities should be constructed for the proposed

bridge site:

1) Temporary roads should be leveled and a sufficient base course should be

provided to cope with the traffic that is unlikely to use them.


[Type text]

2) Regular power supply should be made available from the grid passing

nearby Or electric power will have to be generated by installing diesel-

penetrating sets at the site.

3) Water supply can be arranged by providing underground storage tank and

distribution through a pumping system and overhead tank.

For sewage disposal, septic tank should be provided and if it is not sufficient it

may be necessary to provide oxidation pond.

Site camps are erected on site for resident engineers & persons working on

site. These are in the form of light steel or wooden structure, which are mounted on

skid beams or wheels, so that they can be moved as and when required. These are

provided with electrical, plumbing and sanitary fixture, and the system becomes

operational at site by plugging into the electrical and water supply.

The site is also provided with the latest possible communication technology,

such as cellular phone, Internet, intranet, wan etc.

ORGANIZING UTILITIES

All the utilities and resources available on the proposed bridge should be

organized properly so as to avail the maximum benefit.

Storeroom containing ‘A’ class items should be provided by a watchman’s

cabin adjacent to it.

Steel should stacked in open yard, protected by fencing. The utility yard

should be attached to the steel yard by a common fencing.

Aggregates should be stacked as near as possible to the batching plant or

concrete mix, so as to avoid unnecessary movement and double handling of material.

Camp for persons working on site should be located on one side of the site for

avoiding dust and noise, generated on site.

Store rooms:- Store rooms should be constructed in a place where access for

unloading of materials is easier, which leads to safety of the work forces.

Toilets, latrines should be constructed downwind with proper slope for

drainage.


[Type text]

Specialist shops like steel bender, carpenter, and block makers should be

located/constructed near to their stores or mixer, inside crane radius.

SECURITY :

The proposed bridge site should be secured against possible thefts and damage

causing loss to the governing authority. It should be secured for:

Loss of material, mobile machinery or equipment, at night times or at times

when work is not in progress. 2 nos. of watchmen, each working for a 12-hour shift

will serve for this purpose.

Confidential information prevailing outside the organization: This can be

prevented by storing the confidential data in systems and records, approachable only

to the top management with the M.D. keeping the password key.

All the document, paperwork related to site work should be properly stored in

cupboards under the jurisdiction of a reliable accountant/clerk, acting as a common

person to all the concerned departments.

All the persons working on site, should be well secured against thefts, robbery,

political influence & undue pressure of higher authorities. Also the personnel working

on site should be secured against any sort of mishap or accident, likely to occur due to

negligence of safety conditions.

Reconciliation of materials:

A daily checkup should be done on site specially for the stores, from the

Storekeeper. There are three ways to find out how much money the company is losing

because of damage and deterioration of materials.

a) Looking carefully around the site and checking through the site, usually

shows example of poor placing and storage of materials.

b) Comparing figures given in orders, receipts and issues, and checking of

remaining stocks.

c) Measuring the work done and calculating the materials used.

(i.e. Contract) for mobilization of their staff, machineries & other required resources.

ii) It is the duty of contractor to get himself & his resources mobilized well in

advance before the initiation of work i.e. before the actual execution of work starts

i.e. around a week before, so as to avoid inconvenience to the client & the

subcontractors.


[Type text]

iii) After mobilizing on site physically, he should impart instruction & guidelines to

his staff & sub contractors about the proposed work & thereby the work line of

action. He should also, make his staff well acquainted with the site area & arrange

his machinery in consultation with the client’s engineer so as to avoid unnecessary

wastage of time & materials.

SUBCONTRACTORS:

i) For the proposed work, the contractor has appointed subcontractors related

to various stages of work such as:

Labors for prestressing work.

Labors for placement of tendons.

Labors for casting work.

the actual project work are included. In the Master Control Network and planning for

the project details of enabling work would be included. The extent of enabling work

would vary depending the size and nature of the project. On a large project costing a


[Type text]

few hundred crores, the enabling work itself could form into a mini- project. The

enabling works would include the following items:

i) Fencing/boundary wall around the project, fixing security check post and gates.

ii) Site Office

iii) Camp for accommodating Engineers, Supervisors, and Workmen.

iv) Store for materials

v) Construction Plant and equipment

vi) Static plant such as concrete batching plant, pre-cast concrete element plant, block

making plant, hot mix plant.

vii) Mobile plant such as Trucks, Dumper, Bulldozer Grader, Vibratory and

pneumatic Road Roller, Bitumen sprayer Transit mixer, Concrete Pump,

Crane, front end loader, compressor. These Plant and Equipment are mobile,

and can be shifted from place to place on regular basis.

Stores and suppliers:

Storage areas should be located near to the static plants. For storage of 350

tons of cement, stacking yards should be covered with shed. But here as the cement is

to be used in large quantity for concreting by batching plant and prestressed element

plant, so it is stored in bulk in vertical silos. Also 300 tons of steel is to be stored

which can be stored in open yards with proper fencing and near to bar bender’s

workshop. Care should be taken that water does not get accumulated in this yard and

there is proper slope to drain the rain water. Stone metal and sand can be stored in

open yards, stacked in heaps with proper fencing so that the material does not gets

mix up with the outer material.

The suppliers in the vicinity of talegaon should be invited on site by a formal

notice and a meeting should be held up with the consultation of clients engineer and

contractor, specifying the suppliers clearly about the following factors:

1. quantity of material.

2. quality of material.


[Type text]

3. terms and conditions of contract.

4. mode of transportation.

5. delivery at a short notice.

The suppliers should make the above factors clear in a formal quotation and submit it

to the organization. The department will further scrutinize the quotations of various

suppliers and allot the same to the most optimum supplier.

Workshop

For the maintenance of plant and equipment both static and mobile, it is necessary to

have a workshop which will undertake the maintenance, repair, overhauling and

major replacement of equipment. Workshop is geared up to, carry out preventive and

scheduled maintenance which is essential to keep the break-down of equipment to

bare minimum. The workshop should have facilities for servicing, carrying out

general repair, engine over-haul, calibration of Diesel Pump etc. Workshop should

have a small machine shop attached with lathes, drilling machine, welding, boring

machine, painting, denting, sheet metal work etc. It is also to be equipped with auto-

electrical repair, battery charger, tyre repair etc.

QUERIES: For the proposed bridge site near talegaon, certain queries are searched and

found for arranging materials required for the construction of prestressed bridge

such as:

1) At a distance of 10 kms. from the site, strata below the ground i.e. around 3m

below ground is found adequately hard so as to be used as aggregate after

processing it in crushers.

2) Also at a distance of 25 kms. from the site, along the coastal side, natural sand

is available in plenty known as river sand, which is screened and used as

required.


[Type text]

3) If transportation cost is affordable, then in between Lonavla & Khopoli,

abundant of hard rock, boulder & stones are available, which can be used at

various construction stages of prestressed concrete bridge.

Stores and stacking yards

In the project site, sufficient covered stores or open storage is necessary for

maintaining the material in good condition. Cement is usually supplied in bags, which

is stored at the site in covered shed. The sheds are constructed with brick wall, IPS

floor, tubular structure trusses, roofing with sheets. Bags not exceeding 10 are stacked

one over another. If more than 10 bags are stacked then the lower bags tend to set,

making cement non-usable. In case cement is used in large quantities for concreting

by the batching plant, and pre-cast element plant, is stored in bulk in vertical silos.

The silos are filled up by a pneumatic pump fixed on the cement bulk carrier. From

the silo cement is conveyed into the mixer of the batching plant and pre-cast element

plant, through a screw conveyor.

Services

The site camp is to be provided with services like electric supply, sewage disposal,

communication, telephone. In case regular power supply is available from the grid, it

can be tapped and necessary substation with transformer installed at site. If grid power

is not available then, it may be necessary to generate own power by installing diesel

penetrating se1s at the sets. Water supply can similarly be tapped, if water lines are

passing near by in the vicinity, by providing underground storage tank and

distribution through a pumping system and over head tank. In case water mains are

not available, tube well could be bored for water. Necessary treatment of water to

make it safe for intended consumption will have to be carried out. For sewage

disposal, since the camp is only for a temporary duration septic tank, could be

provided. If it is a large site, and enough land is available, then it may be possible to

provide an oxidation pond for sewage disposal. The effluent from the pond could be

used for horticultural purposes of the site.

In order to carry out the enabling work which is required at the very initial stage of

the project itself, it may be desirable for the organization, to set up a 'crack team'

which can go in advance to the site and build up all the temporary structures, services

required for the enabling works. This will cut down the time required by the main

project team, on their arrival at the site, and they could embark upon straight-away on

execution of the main project. Such a 'crack team' can move from project to project

for the organization, and they would be well trained in carrying out this activity. On

the other hand, if project team assigned with the main work, is to first build up the

enabling works, a lot of time is lost for the project.

On most international project, and on some major projects within country, of structure

being adopted for the site camp are of portable nature. These are in the form of light

steel or wooden structure, which are mounted on skid beams or wheels, and can be

moved to the camp site, at a very short notice. The Port cabins are provided with

electrical, plumbing and sanitary fixture, and the system becomes operational at site

by plugging into the electrical and water supply. Through the initial cost of the system

may be more but over a period of time it would become economically viable since the

structure can be shifted to site, where as, if the camp is built with conventional

materials. like steel, concrete, the cost would be higher in the longer run, besides the

extra time required to build the Camp.

TRANSPORTATION:

The proposed bridge site is at Talegaon, located 35 kms away from Pune. The

means of transportation are as follows:

i) For staff workers & engineers, not residing on site, a minibus is arranged

by the organization for their daily conveyance.

ii) In case of emergencies, such as fatal accident or injury on site, the

organization has arranged an ambulance in the form of omni-van with

small stretcher laid inside the van.


[Type text]

iii) For immediate or unexpected requirement of material o site, 2 standby

trucks are arranged for conveyance of material on site from around the

vicinity of 100 kms from site.

iv) For receiving consultants and executives from the nearest terminal, an

automobile such as Scorpio or Qualis is arranged by the organization.

All the expenses required for the above conveyance are added into the total cost of the project as contingencies.
