C-Lump-sum: In this type of contract the contractors are required to give fixed rate / fixed sum for execution of work complete in all respects i.e. according to drawings, designs, specifications supplied to them with tender within specified time. (Departmental schedule of rates for various items of works are also provided which regulates the payment of contractor in respect of items of works added / deleted.) In this type of contract the detailed planning, design & drawings for work along with the specifications should be ready & should be final. As the rate is paid on sqft basis the exact idea of work to be carried out along with the foundation requirements & site details should be ready before the tender document is prepared. Extensive detailing is required in tender document for technical specifications & drawings. The schedule of payments detailing the part payment for each item of work, Portion executed is required to be prepared which cannot be standardized & differs from work to work. Since the payments are not made on measurements of quantities the changes in the drawings become very difficult, as their quantum cannot be judged readily. Since the payments are to be made on built up area basis detailed definition of built up area should be given. As to what shall be payable, as BUA for FSI purposes often allows various concessions, which are required to be incorporated in payable, built up area like, machine room, lift well, pump house etc. In this type of contract the important thing is to judge exact quantum of the work done by the contractor at a particular stage for payment of interim running bills. In absence of proper judgment the case of excess payments have occurred in past. The reason may be casual approach in working out quantum of work as no detailed measurements are records .It is therefore necessary to work out the system for calculation for quantum of work & get it approved from competent authority.
Lump sum Turnkey / Design & Built form: This type of the contract form is generally used mass housing projects, where the contractor apart from the execution of work also plan & design the work, i.e. client do not plan or design. This job is also done by the agency. However in this type of contract client must be able to detail out our needs specifically in regards Architectural Planning Brief. 2) Architectural Aspects Requirements. 3) Structural Design Criteria 4) On / Off Site Infrastructure Design Criteria 5) General Specifications 6) Scope of work. In this type of contract generally the bids are invited from selective agencies, which are prequalified for such types of projects The bids are invited in three envelopes: Documents Technical offer. Financial offer. The evaluation of technical Bid is Herculean task. The marks are given for each stage / requirements detailed out in Bid & the financial offers of only those who are found technically suitable are opened. This type of contract eliminates the need of appointment of architect for planning portion. The type of contract is easy to monitor since planning & requisite permissions are the responsibilities of the contractor & are well defined.
