approved materials at site and of work done to date by the contractor will be paid for

in full at the rate specified in the contract. Notice in writing from the Owner of such

determination and the reason therefore shall be conclusive evidence thereof.

47. Payment on determination of contract:

Should the contract be determined , the contractor shall have no claim to any

payment of compensation or otherwise howsoever on account of any profit or

advantage which he might have derived from the execution of the work in full but

49. Procedure of determination of contract:

Then and in any of the said cases, the Architect on behalf of the Owner may serve

the contractor with a notice in writing to that effect and if the contractor does not

within seven days after the delivery to him of such notice proceed to make good his

default in so far as the same is capable of being made good and carry on the work or

comply with such directions as aforesaid to the entire satisfaction of the Architect, he

shall be entitled after having 48 hours notice in writing from owner (to rescind the

contract as a whole or in part or parts as may be specified in such notice) and adopt

either or both of the following courses:-

b) To measure up the whole or part of the work from which the contractor has been removed and to get it completed by another contractor in the manner and method in which such work is completed, shall be at the entire discretion of the Architect whose decision shall be final.

And in both the cases (a) & (b) mentioned above, Owner shall be entitled (i) to forfeit

the whole or such portion of the security deposit as it may consider fit; and (ii) to

recover from the contractor the cost of carrying out the work in excess of the sum

which would have been payable according to the certificate of the Architect to the

contractor if the works had been carried out by the contractor under the terms of the

contract, such certificate being final and binding upon the contractor. Provided,

however, that such recovery shall be made only when the cost incurred in excess is

more than the security deposit proposed to be forfeited and shall be limited to the

amount by which the cost incurred in excess exceeds the security deposit proposed

to be forfeited. The amounts thus to be forfeited or recovered may be deducted from

any moneys then due or which at any time thereafter may become due to the

contractor by the Owner under this or any other contract or otherwise.

reason of his having purchased or procured any materials or entered into any

commitments or made any advances on account of or with a view to the execution of

the work or the performance of the contract and contractor shall not be entitled to

recover or be paid any sum for any work thereto or actually performed under the

contract unless and until the Architect shall have certified the performance of such

work and the value payable in respect thereof and the contractor shall only be

entitled to be paid the value so certified.

sum of sums (if any) as the Architect may certify would have been due to him upon

due completion by him after deducting the said amount, but if such amount shall

exceed the sum which would have been payable to the contractor, then the

contractor shall on demand pay to the Owner the amount of such excess and it shall

be deemed, debit due by the contractor to Owner and shall be recoverable

accordingly.

time, then a fixed amount, which is supposed to be spent on that particular work will be

deducted from the running bills of the contractor as per Architect‟s estimate and decision of

the Architect shall be final and binding on the contractor.

for joints, nuts & bolts , duct supports & hangers, vibration isolation pads or suspenders,

will be required to complete the duct installation except external insulation and acoustic

lining.

The external area shall be calculated by measuring the overall width and depth (including the

corner joints) in the centre of the duct sections and overall length of each duct section from

flange face incase of duct lengths with uniform cross section. Total area will be arrived at by

adding up the areas of all duct sections.

In case of taper pieces average width and depth will be worked out as follows :

W1 = width of small cross section

W2 = width of large cross section

D1 = depth of small cross section

D2 = depth of large cross section

Average width = W1 + W2

2

Average depth = D1 + D2

2

Width and depth in the case of taper pieces shall be measured at the edge of the collar of the

flange for duct sections fitted with angle iron flanges, otherwise at the bottom of the flange

where flanges are of duct sheet.

For the circular pieces the diameter of the section mid-way between large and small diameters

shall be measured and adopted as the mean diameter for calculating the surface at the taper

piece.

For the face length of taper piece shall be the mean of the lengths measured face to face from

the centre of the width and depth of flanges.

For the special pieces like bends, branches, and tees etc. same principle of area measurement

as for linear lengths shall be adopted except for bends and elbows, the length of which shall

be the average of the lengths of inner and outer periphery along with curvature or angle of the

piece.

21.2 Duct Insulation

This item is provided separately for various thickness and shall be paid for on area basis of

un-insulated duct. The area of the duct to be insulated shall be measured before application of

insulation.

21.3 Grilles & Diffusers

All extruded aluminium grilles and diffusers shall be paid on the basis of actual measurement

at site on area basis using neck size as base for diffusers having outer size less than 600mm.

For 600mm x600mm size diffusers being installed in grid ceiling, shall be counted at site

and payment shall be made on unit basis. Slot diffusers shall be paid on actual measurement at

site on running length basis.

21.4 Piping

Payment for refrigerant piping and condensate drain piping shall be made on the basis of

linear measurement including all material and labor for installed pipes. The linear rate per

meter/feet for each nominal diameter shall include all pipe fittings except refnet joints, pipe

supports & hangers, vibration isolation arrangement, closed cell elastomeric insulation

material and any other item required to complete the pipe installation except valves of any

kind and strainers. The length of the pipe section with flanges shall be from flange face to

flange face.

For fitting like bends, elbows, branches, reducers, tees etc. same principle of linear

measurement as for pipe sections shall be adopted except for bends, the length of which shall

be the average of the lengths of inner and outer periphery along the curvature.

22. All quantities reflected in the schedule are for contractor‟s guidance only.
