Contract dates may look like simple administration, but they can have a major commercial impact on a construction project.
For Quantity Surveyors, dates are not just entries in a diary. They can affect payment, notices, extensions of time, delay damages, loss and expense, compensation events, variations and final account recovery.
If key dates are missed or misunderstood, the commercial position can quickly become weaker. This is why every QS should understand the important dates in the contract before the project starts.
Contract Dates Control Payment
One of the most important areas where dates matter is payment.
Most construction contracts include specific dates for payment applications, payment notices, pay less notices and the final date for payment.
If these dates are not managed properly, disputes can arise very quickly.
For example, if a contractor or employer misses the deadline for issuing a valid pay less notice, they may be required to pay the notified sum, even if they disagree with the amount applied for.
This is why payment dates should never be left to memory.
A QS should have a clear payment tracker showing:
- the application date;
- the due date;
- the payment notice deadline;
- the pay less notice deadline;
- the final date for payment.
These dates should be reviewed every payment cycle.
Dates Affect Delay Entitlement
Contract dates are also critical when dealing with delay.
A construction contract will usually include a start date, completion date and possibly sectional completion dates. These dates are used to assess whether the works are progressing on time and whether delay damages may apply.
If the contractor is delayed, the contract may require notices to be issued within a specific period. If those notices are late or not issued properly, entitlement to additional time or money may be affected.
This matters because delay claims are not only about proving that a delay happened. They are also about showing that the correct contractual process was followed.
A QS should understand:
- when the works are due to start;
- when the works are due to complete;
- whether there are sectional completion dates;
- when delay notices must be issued;
- when extension of time submissions are required;
- when supporting information must be provided.
Missing these dates can make a valid claim much harder to recover.
Dates Help Manage Change
Variations and compensation events are another area where dates are important.
Under many contracts, changes must be notified, instructed, priced or assessed within certain timeframes. If the team does not understand these deadlines, change can become difficult to manage.
This is especially important when costs are being incurred on site before the commercial position has been agreed.
A QS should make sure there is a clear change control process in place from the start of the project. This should include a tracker showing when changes were instructed, notified, priced, submitted, reviewed and agreed.
Good date management helps protect entitlement and reduces the risk of arguments later.
The QS Should Set the Process Early
A good QS should not wait until a problem arises before checking the contract dates.
At the start of the project, the QS should review the contract and identify the key dates that affect payment, change, delay and completion.
These should then be shared with the project team in a clear and practical way.
The aim is not just to understand the contract. It is to turn the contract into a working commercial process.
How Metroun Can Help
At Metroun, we help contractors, subcontractors and project teams understand their contractual and commercial obligations.
From payment procedures and change control to delay, entitlement and contract administration, we help turn contract requirements into clear commercial actions.
Final Thoughts
Contract dates matter because they can decide entitlement, payment, risk and recovery.
For Quantity Surveyors, it is not enough to know the value of the works. You also need to know when applications, notices, responses and submissions are required.
The key message is simple:
Know the contract.
Diarise the dates.
Track the deadlines.
Protect the commercial position.
Because in construction, missing a date can cost money.
