How We Quote Construction Prices: Absolute Transparency, Zero Surprises
At Om Muruga Group and Amman Contractors, we do not provide vague ballparks. Every quotation is backed by a certified Bill of Quantities (BOQ), structural IS Code specifications, and milestone-linked physical progress disbursements.
Our 5-Stage Scientific Cost Estimation Process
How our Civil Engineers formulate exact, risk-free construction pricing before breaking ground.
Soil Bearing Survey
We evaluate Safe Bearing Capacity (SBC) and strata depth to design the exact foundation (Isolated, Raft, or Pile) without structural over-design or dangerous under-budgeting.
Architectural CAD Layout
Detailed 2D floor plans and 3D elevations calculating precise plinth area according to IS 3861 standards and municipal setback regulations.
Quantity Take-Off (BOQ)
We extract exact metric tonnes of Fe550D steel, bags of 53-grade cement, cft of coarse M-Sand, and square feet of tiles to build an itemized Bill of Quantities.
Material Brand Schedule
Clear, contractual brand commitments across structural steel (Tata Tiscon/JSW), cement (Ramco/Dalmia), CP fittings (Jaquar), and wires (Finolex).
Milestone Payment Plan
You disburse funds strictly across 7 physical inspection milestones (Foundation, Plinth, Roofs, Plastering, Finishing). Zero advance risk.

Frequently Asked Questions on Construction Pricing
What happens if steel or cement prices increase during construction?
We execute Fixed-Price Turnkey Contracts. Once the contract and Bill of Quantities (BOQ) are signed, material price fluctuations are absorbed by Amman Contractors through strategic bulk procurement with manufacturers, protecting you against cost overruns.
How is the Plinth Area measured for quotation?
Plinth area is measured strictly according to Indian Standard IS 3861 (Method of Measurement of Plinth, Carpet and Reference Areas for Buildings). It represents the built-up area measured at the floor level of the basement or any storey, taking external dimensions of outer walls.
Are architectural designs, structural drawings, and municipal approvals included?
Yes. All our turnkey construction packages include 2D architectural CAD floor plans, 3D photorealistic elevations, structural column/beam details, and electrical/plumbing layout drawings prepared by our in-house civil engineers.
What warranty do you provide after handing over the house keys?
We provide a comprehensive 1-Year Free Maintenance Warranty covering any structural settlement rectifications, plumbing leaks, electrical switch adjustments, or woodwork seasoning alignments. Termite treatment carries a 10-year manufacturer warranty.
