What Should Be Included in a Construction Contract?
A construction contract should answer the questions that become uncomfortable later: “Kasama ba ito?”, “Kailan ang billing?”, “Paano ang additional work?”, and “Ano ang mangyayari kung may delay?”
A good construction contract should connect the approved scope, drawings, specifications, BOQ, payment schedule, project duration, variation procedure, responsibilities, warranties and turnover requirements in one clear document set.
By the time a project reaches contract signing, the main commercial conversations should already be visible in writing. The contract is not just paperwork for the start—it becomes the reference when memories and assumptions differ months later.
The contract is only as clear as its attachments
A signed agreement can still create disputes if the approved plans, specifications and BOQ are unclear or inconsistent. We prefer the contract to identify exactly which drawing set and scope documents form part of the agreement.
Payment terms should be tied to something measurable
“Progress billing” sounds clear until two parties calculate progress differently. Define the down payment or mobilization requirement, billing milestones, documentation needed for each claim, retention if applicable, and the conditions for final release.
Additional work needs a written path before additional work happens
Variations are normal in construction. What creates trouble is doing them first and negotiating the cost later. A cleaner process is: identify the change, describe the scope and price effect, secure written approval, then execute.
Items we would settle before signing
- Complete project scope and exclusions
- Approved plans, specifications and BOQ reference
- Contract amount and taxes
- Payment and progress-billing schedule
- Project duration and extension conditions
- Variation/change-order process
- Owner-supplied items, utilities and site responsibilities
- Warranty, punchlist and turnover requirements
A good contract protects the relationship—not only the contractor
Clear responsibilities reduce the need to argue from memory. The owner knows what is included and when payment becomes due; the contractor knows what must be delivered and how approved changes will be handled. That clarity is part of project control.
Frequently asked questions
Should the BOQ be attached to the contract?
It is often useful when the BOQ forms part of the agreed pricing and scope basis. The contract should identify which documents govern the work.
What is a change order?
A written change to the agreed scope, price or time. It helps prevent verbal additions from becoming disputed later.
What is retention?
An agreed portion of payment held back until defined completion or defect-related conditions are satisfied.
What should the contract say about delays?
It should define project duration, allowable extensions, owner-caused delays, force-majeure or excusable events, and the process for documenting time impacts.
Is this article legal advice?
No. It is practical construction guidance. Project-specific contracts should be reviewed according to the actual transaction and applicable legal requirements.
Review the scope before the signatures
If a contract paragraph depends on an assumption, clarify it while the project is still calm. It is much easier to define responsibilities before mobilization than during a dispute.
