Quantity Surveying & Commercial Cost Management

Service Overview

Our Quantity Surveying (QS) Services are designed to give developers, contractors, and corporate investors total control over construction capital. From the initial feasibility analysis to final accounts closure, our team provides physical verification of materials, tracks labor productivity, manages contract claims, and certifies payment certificates. By acting as independent financial audits on the ground, we insulate construction budgets from waste, inflated contractor variations, and timing overruns.

Why Choose Professional Quantity Surveying?

Managing construction costs involves a continuous cycle of verification. Structural components like concrete foundations, reinforcement steel rebar, structural block walls, and architectural finishes must be physically surveyed and validated.

With raw material prices experiencing high volatility, minor deviations in takeoff calculations can quickly snowball into multi-million variations. Our quantity surveyors establish systematic measurement schedules under IS 1200 guidelines, checking each contractor claim against actual site measurements before you disburse funds.

Key Benefits of Quantity Surveying

Accurate Progress Payments: Ensure contractors are only paid for work that is physically completed on site.
Early Risk Mitigation: Track budget slippage on a monthly basis, catching cost overruns before they escalate.
Rigorous Contract Administration: Manage variation orders, extension of time (EOT) claims, and contract disputes with legally defensible documentation.
Material Yield Audits: Compare actual material consumption on-site with standard theoretical models to identify theft or waste.

Scope of Work & Deliverables

We provide end-to-end commercial control across all project stages:

Subcontractor Bill Auditing: Physical measurement of work executed on site, verification of rates, and preparation of Interim Payment Certificates (IPC).
Variation Management: Independent assessment of structural or architectural changes requested by the design team, ensuring competitive pricing.
Cash Flow Forecasting: Monthly projections of project cash flow requirements based on master construction schedules.
Final Account Settlements: Reconciliation of all variations, provisional sums, and prime cost items to close contracts smoothly.

Case Study: 120,000 Sq. Ft. IT Park in Chennai

Project: Kadamban Tech Plaza, OMR, Chennai

Client Challenge: A developer encountered significant budget deviation during structural casting. Subcontractors submitted monthly invoices containing 18% higher concrete and formwork quantities than specified in the architectural layouts.

Our Solution: The Estimation Company deployed a dedicated QS team to execute joint measurements with the contractor's surveyor. We audited concrete transit mixer delivery slips, verified slab formwork dimensions, and checked structural steel overlaps.

Financial Outcome: We identified ₹58 Lakhs of over-billing due to unadjusted structural openings (lift shafts/ducts) and scrap steel weight calculations. The final billing adjustments saved the developer 6.2% of the overall structural package budget.

Frequently Asked Questions

A quantity surveyor on site monitors material consumption, records joint measurements, verifies structural steel bar bending schedules (BBS), reviews contractor variations, compiles monthly cash flows, and certifies progress invoices to protect the developer from over-billing.

We check all variations against three parameters: (1) validity under the core contract, (2) physical necessity verified via site drawings, and (3) rate alignment with standard market prices or CPWD Schedule of Rates. Only variations passing these audits receive certification.

Yes. While our primary focus is commercial structures and residential townships, we offer remote quantity auditing and initial BOQ validation for high-end villas and custom home builds to shield owners from contractor cost overruns.

We perform theoretical material checks (e.g., matching the volume of brick masonry built against the number of blocks delivered). If actual material usage exceeds standard limits, we alert project managers of poor site yield patterns or scrap loss issues.
