In the world of construction, quantity surveying plays a crucial role in managing costs, ensuring projects stay on budget, and maintaining effective communication between all parties involved. One key aspect of this is the use of contracts. But, with so many different types of contracts out there, it can get a bit overwhelming to figure out which one to use. In this article, we’ll break down the different types of contracts used in quantity surveying, explain their purpose, and explore when each type is most beneficial.
So, whether you’re a budding quantity surveyor or someone involved in construction projects, keep reading to discover what these contracts are all about and how they affect the construction industry.
What Are Contracts in Quantity Surveying?
Before diving into the types of contracts, let’s first understand what contracts in quantity surveying actually are. In simple terms, a contract is an agreement between two or more parties that outlines the terms and conditions of a project, including cost, timeline, responsibilities, and deliverables.
In construction, a contract ensures that both the client (the one paying for the project) and the contractor (the one doing the work) agree on certain key points such as how much the project will cost, how long it will take, and what materials and labor will be used.
Why Are Contracts So Important in Quantity Surveying?
Contracts are the backbone of any construction project. Without them, projects would be chaotic, with no clear expectations or guidelines. They help manage risks, prevent disputes, and ensure that both the client and contractor are on the same page. In quantity surveying, these contracts are carefully prepared to control costs, set timelines, and establish how payments will be made.
Now, let’s take a closer look at the most common types of contracts used in quantity surveying.
What Are the Different Types of Contracts in Quantity Surveying?
- Lump Sum Contract (Fixed Price Contract) A Lump Sum Contract is one of the most common types used in construction projects. In this contract, the contractor agrees to complete the project for a fixed price. The price is agreed upon before the work starts and doesn’t change unless there are significant changes to the project scope. Advantages of Lump Sum Contracts:
- Clear cost expectations: The client knows upfront how much they will need to pay.
- Simplifies budgeting: The contractor has to manage costs within the agreed sum.
- Risk management: The contractor bears the risk of cost overruns.
- Limited flexibility: If there are unexpected changes or additions to the project, it can be difficult to adjust the contract.
- Potential for lower-quality work: Contractors may cut corners to stay within the fixed price.
- Measure and Value Contract (Cost-Plus Contract) A Measure and Value Contract, also known as a Cost-Plus Contract, allows the contractor to charge for the actual cost of labor, materials, and overheads, along with an additional percentage or fee as profit. Advantages of Measure and Value Contracts:
- Flexibility: It works well when the project scope is unclear or likely to change.
- Transparency: Clients can see the breakdown of actual costs.
- Fairer distribution of risk: If the project goes over budget, the contractor shares the burden.
- No guaranteed cost: The client doesn’t know exactly how much the project will cost.
- Potential for cost escalation: If not managed properly, costs can spiral out of control.
- Less incentive to finish quickly: Since the contractor is paid based on costs, they may have less motivation to reduce time and expenses.
- Time and Material Contract A Time and Material Contract is a type of agreement where the client pays the contractor based on the time spent and materials used for the project. The hourly labor rates and cost of materials are agreed upon upfront. Advantages of Time and Material Contracts:
- Flexibility: Ideal for projects with uncertain timelines or evolving requirements.
- Easier to adjust scope: Changes can be made without renegotiating the whole contract.
- Transparency: The client pays for the actual time and materials used.
- No cost certainty: The client doesn’t know exactly how much the project will cost.
- Risk of inefficiency: Contractors may take longer or use more materials, knowing they will be paid based on time and resources.
- Potential for disputes over time spent or materials used.
- Unit Rate Contract In a Unit Rate Contract, the contractor is paid a set rate per unit of work completed. For example, the price could be set per square meter of wall or per cubic meter of concrete poured. Advantages of Unit Rate Contracts:
- Provides flexibility for changing quantities of work.
- Easier for clients to track costs based on the work completed.
- Risk is shared: The contractor only gets paid for what is done.
- Measurement discrepancies: Accurate measurement is crucial to avoid disputes.
- Difficulty in pricing unknown quantities: Some projects may involve unknown or variable work amounts, making this contract type tricky to estimate.
- Design and Build Contract A Design and Build Contract combines both the design and construction phases of a project. In this type of contract, the contractor is responsible for both designing the project and building it, streamlining the process and reducing the client’s involvement. Advantages of Design and Build Contracts:
- Single point of responsibility: The client deals with one party for both design and construction.
- Faster project delivery: The design and construction phases can overlap, saving time.
- Potential cost savings: Contractors may find ways to reduce costs due to their involvement in both design and build.
- Less client control over design: The client has limited influence over the design process.
- Potential for lower-quality design: Contractors may prioritize cost-saving over aesthetics.
- Management Contract A Management Contract involves the client hiring a construction manager to oversee the project. The manager coordinates the work but doesn’t directly carry out the construction. The contractor works under the management team. Advantages of Management Contracts:
- Flexibility in project execution.
- Easier to manage large or complex projects with multiple subcontractors.
- Reduces client involvement in day-to-day construction tasks.
- Requires skilled management: The success of the project depends on the ability of the manager.
- Potential for conflict between manager and contractor.
Do You Know? Key Facts About Construction Contracts
- A lump sum contract is often preferred by clients who want certainty in costs, but it can be risky for contractors if unforeseen circumstances arise.
- The cost-plus contract is ideal for projects where unexpected issues might arise, but it can lead to disputes over whether costs are reasonable.
- Time and material contracts are particularly useful in maintenance or small-scale projects where timelines and resources are hard to predict.
Do’s and Don’ts in Quantity Surveying Contracts
Do’s:
- Do ensure clarity in your contract terms: Always ensure both parties understand their obligations.
- Do keep a close eye on your budget: Whether it’s a lump sum or time and material contract, controlling costs is crucial.
- Do use professionals: Work with experienced quantity surveyors to draft and manage contracts.
Don’ts:
- Don’t ignore potential risks: Always consider the possible risks of cost escalation.
- Don’t rush into contracts without understanding the terms: Take the time to review and fully understand the contract before signing.
- Don’t assume all contracts are the same: Different types suit different project needs.
Frequently Asked Questions (FAQs)
- What is a lump sum contract?
- A lump sum contract is an agreement where the contractor agrees to complete a project for a fixed price.

- When should I use a unit rate contract?
- A unit rate contract is useful for projects that involve measurable units of work, like road construction.
- Why is the design and build contract popular?
- It is popular because it combines design and construction under one contract, streamlining the process.
- What’s the difference between time and material contracts and measure and value contracts?
- Time and material contracts are based on time spent and materials used, while measure and value contracts are based on actual cost and a percentage fee.
- Can contracts change during a project?
- Yes, contracts can change with mutual agreement, especially if the project scope evolves.
