What We Do

Model-Based Cost Control That Eliminates Budget Surprises

5D BIM Cost Estimation brings financial intelligence directly into the building model. At HRP Infra, Ahmedabad, we attach cost parameters to every BIM element — from a single RCC column to an entire building floor plate — enabling automatic quantity extraction and live cost reporting that evolves with your design.

Traditional quantity takeoff from 2D drawings is time-consuming, manual, and error-prone. Our BIM-based approach extracts quantities automatically from the model geometry, applies current market or government schedule rates (CPWD/DSR, GWSSB, GERI for Gujarat), and produces construction-ready BOQ within a fraction of the time — with far greater accuracy.

CPWD/DSR Compliant: BOQ prepared as per CPWD Schedule of Rates and state PWD rate schedules for government projects.

Dynamic Cost Updating: Any design change instantly updates quantities and costs — no re-measurement required.

DPR-Ready Output: Structured BOQ and cost estimates formatted for Detailed Project Report (DPR) submissions to government authorities.

Why 5D BIM

Why Choose BIM-Based Cost Estimation?

5D BIM transforms cost estimation from a periodic exercise into a continuous, model-integrated financial management capability.

Higher Accuracy

Quantities extracted directly from the model eliminate manual measurement errors, delivering ±2% accuracy compared to ±10–15% for traditional 2D takeoff.

10× Faster Takeoff

BIM-based automated quantity extraction completes in hours what traditional 2D takeoff would take days or weeks to accomplish for complex projects.

Instant Design Updates

When design changes occur, quantities and costs update automatically — keeping the estimate aligned with the current design without re-measurement.

DPR & Tender Ready

Structured BOQ formatted for CPWD, GWSSB, GERI, and PWD government DPR submissions — meeting all standard Indian tender documentation requirements.

Value Engineering Support

Cost-model integration enables rapid comparison of design alternatives, supporting value engineering decisions with instant cost impact visibility.

Procurement Support

Detailed trade package pricing supports contractor procurement, tender evaluation, and contract award with a consistent, model-derived cost basis.

FAQs

Frequently Asked Questions

What is 5D BIM Cost Estimation?

5D BIM adds cost as the 5th dimension to a 3D BIM model. By linking cost parameters to individual model elements in Revit, quantities are automatically extracted and priced — generating live BOQ and cost estimates that update dynamically whenever the design changes. This eliminates manual re-measurement and ensures budgets stay current throughout the design process.

How is 5D BIM more accurate than traditional quantity takeoff?

Traditional quantity takeoff measures 2D drawings manually — a process subject to human error, scale inconsistency, and omissions. 5D BIM extracts quantities directly from the 3D model geometry, achieving ±2% accuracy. When the design changes, quantities update automatically without any re-measurement, keeping estimates always aligned with the latest design.

Which rate schedules does HRP Infra use for cost estimation?

HRP Infra references CPWD Schedule of Rates (DSR), Gujarat PWD schedules, GWSSB rates (water sector), and GERI norms (irrigation structures) for government projects. For private sector work, we use current market rates from supplier and sub-contractor quotations. For international clients, we can apply RICS NRM or project-specific rate libraries.

Can 5D BIM cost estimates be used for government DPR preparation?

Yes. HRP Infra has extensive experience preparing DPRs for government infrastructure projects in Gujarat. Our 5D BIM-based BOQ and cost estimates are structured to meet CPWD/PWD DPR format requirements and can be directly used for government sanction and tender submissions to GWSSB, GERI, NHAI, PMGSY, and state PWD authorities.

What output formats does HRP Infra deliver for 5D BIM?

We deliver: structured BOQ in Excel (formatted for client and government requirements), PDF cost reports for submission, Revit schedule exports (CSV/Excel), elemental cost plans, and optionally linked spreadsheet models that dynamically update with model changes using Dynamo or manual exports.
