Answer: In the construction industry, there are several types of contracts that a Quantity Surveyor may encounter, each with different terms and conditions related to cost, time, and responsibility. Some of the most common types include:

Lump Sum Contract:
- This is a fixed-price contract where the contractor agrees to complete the work for a specified price. It’s the simplest contract type and often used for straightforward projects. The key advantage is that it provides a clear, predictable cost for the client. However, it can lead to issues if the scope of the work changes or unforeseen complications arise.
Cost-Plus Contract:
- In this type of contract, the client agrees to pay the contractor for the actual cost of the work plus a fixed percentage as a fee. This type offers more flexibility for the contractor but can lead to higher costs for the client. It’s ideal for projects where the scope may change, and exact costs cannot be predicted upfront.
Unit Rate Contract:
- Payment is based on the number of units of work completed. For example, a contractor may be paid per square meter of concrete poured or per meter of drainage pipe installed. This contract type is suitable when the quantity of work can be measured easily, but the total work is not entirely clear at the outset.
Target Cost Contract:
- This contract sets a target cost for the project, and if the project is completed under budget, both the client and contractor share the savings. If the cost exceeds the target, the contractor may have to absorb part of the overrun. This contract helps encourage cost savings and collaborative problem-solving.
Design and Build Contract:
- In this contract, the contractor is responsible for both the design and construction of the project. It simplifies communication between parties but places the contractor in charge of both cost and design decisions. The client benefits from a single point of responsibility.

Each contract type has advantages and risks, and the choice depends on the specific needs of the project, including the level of certainty in costs, the complexity of design, and the nature of the construction work.
