Quantity Surveying (QS) & Cost Estimation

Quantity Assurance and Quantity Survey

Stable Inter Co., Ltd. provides services including construction quantity surveying (Quality Assurance) and work quantity calculation (Quantity Survey).

Quality assurance (QA) is the process of verifying the quantity of work and materials performed by the contractor to ensure that the work and materials used match the specifications in the contract. This is used to confirm payments and issue payment certificates.

Quantity surveying (QS) is the process of capturing the types of work, the quantity of materials, and labor costs.

And the various operating costs of construction, including all building systems, are included to determine the total construction cost.

For buildings or factories, the estimated price may be subject to discrepancies due to engineering safety margins and varying pricing methods used by different contractors, unless the official price list from the Comptroller General's Department is used as the primary reference for recording the cost.

Who is this service suitable for?

• Project owners preparing to tender a project need to know the true "average price" in order to compare and negotiate with contractors and avoid being taken advantage of.

• Employers seeking transparency in payments: They want an independent third party to verify the actual work completed on-site before approving payment installments, to prevent overpayment for the actual work done.

• Projects requiring precise cost control: Need to know the true cost of materials and labor to manage the project's cash flow effectively.
