๐๏ธ Mastering Construction Contracts: What is a Provisional Sum? ๐ ๏ธ
Ever wonder how construction projects handle parts of a building that aren't fully designed yet? Thatโs where Provisional Sums (PS) come in!
What is it? ๐ A Provisional Sum is a specific amount included in a contract for works, materials, plant, or services that cannot be fully measured or described at the time of the agreement
The Two Main Types: โ๏ธ Defined PS: The work isn't fully designed, but the contract provides the nature of the work, its location, the scope/quantity, and any specific limitations Undefined PS: This sum is provided when the detailed information required for a "defined" sum simply isn't available yet
How it Works in Practice: โ๏ธ Fixed Amount: A specific figure (e.g., Rs. 900,000 for landscaping or Rs. 1.5M for security systems) is inserted into the Bill of Quantities (BOQ) Instruction: During construction, the Engineer identifies and instructs the work to be carried out Ex*****on: The Contractor or a Nominated Subcontractor executes the task Payment: Instead of the original estimate, the Contractor is paid the actual cost plus overheads and profit For Nominated Subcontractors, the payment includes actual amounts plus a fee for attendance (general or special services) provided by the main contractor
Why use them? ๐ค They are essential for anticipated works without firm designs or for work handled by statutory undertakers
This ensures the project keeps moving even when every detail isn't finalized on day one! ๐๏ธ๐
