What is good project QSing?

At Quentessential, good project Quantity Surveying is the proactive, forward management of commercial, contractual, and financial performance throughout the construction phase and close-out of the project. This ensures that all projects are completed in strict conformity with the budget, contract, and programme.

Effective post-contract Quantity Surveying covers more than ordinary cost monitoring. It includes the continuous assessment of progress, management of variations, administration of contracts, commercial risk management, and negotiation and agreement of final accounts. For effective and clear quantity surveying, there is a need for clarity, transparency, and control in all financial aspects.

Our approach maintains commercial discipline from contract award to completion, ensuring all parties are accountable for financial performance and contract compliance.

Why is it important?

The role of Post Contract Quantity Surveying is to secure contract profitability and provide financial security to the firm. The construction environment is dynamic — design changes, site conditions, supply chain issues, and programme variations can significantly impact outcomes.

Through effective cost control, change management, and contract administration, Quentessential ensures projects remain commercially stable, viable, and aligned with client objectives. Our involvement supports accurate valuations, effective cash flow management, and transparent handling of variations.

Strong commercial management after contract award minimises disputes, promotes collaboration, and enables successful financial close-out while protecting stakeholder interests.
