Generate MoRTH BOQ from cross-sections. Price it with live rate data.

Upload TCS cross-section drawings. CivilBolt reads the geometry and generates the chapter-wise BOQ: clearing, earthwork, pavement, drains, structures, road furniture, with MoRTH SDB rate templates and an 8-level NHAI cost cascade built in.

Estimators overview

The current process

A 42km NHAI tender. Three weeks. One QS.

The BOQ lands. The QS opens the cross-section drawings: 60 sheets for a 42km stretch. Typical sections get measured with a scale rule. Unusual sections get triangulated by hand. The earthwork volumes go into an Excel sheet built three years ago.

Then the rates. MoRTH SDB 2019 is a PDF. The QS copies item by item into the BOQ workbook. OH and profit percentages come from the previous tender. Nobody has checked the state PWD SOR update from last quarter.

The estimate is done by day 15. Pre-bid queries, structural assumptions, and mass haul optimisation don't happen. There is no time left.

With Road Estimator

Upload the TCS drawings on day one. CivilBolt reads the geometry and builds the chapter-wise BOQ. Rate analysis runs against the built-in MoRTH SDB 2019 templates. The QS spends the remaining time on what a QS should actually do: structural assumptions, mass haul optimisation, scenario comparison.

  • Chapter-wise BOQ quantities from TCS geometry, not from a scale rule
  • 33 MoRTH SDB items with full labour + material + OH + profit build-up
  • Interactive mass haul: drag balance points, see ₹ impact live
  • NHAI 8-level cost cascade from civil total to Grand Total
  • Pre-bid validation before export: missing rates, below-cost items

Cut & fill

Scrub the alignment, see the earthwork. Drag along the long-section and read the cut, fill, and volume at any chainage.

From cross-sections to bid submission in 8 steps

Each step feeds the next. TCS geometry drives BOQ quantities. BOQ quantities drive rate analysis. Rate analysis drives the NHAI cost cascade. The cascade drives the export.

1

TCS Templates

Upload PDF cross-section drawings. CivilBolt reads the geometry: carriageway width, pavement layers, cut/fill slopes, median, shoulders.

2

Chainage Plan

Map which TCS applies from chainage X to chainage Y. Multiple TCS types on the same stretch, each gets its own row.

3

L-Section

Import L-section data. CivilBolt computes cut and fill volumes at every station using the IRC prismoidal formula, not trapezoidal approximation.

4

Assumptions

Add drains, retaining walls, bridges, culverts, junctions, bus bays. Each with geometry inputs. CivilBolt computes quantities from dimensions, not from memory.

5

Analysis

Interactive mass haul diagram. Drag balance points, see the ₹ impact live. 3D corridor with pavement layer cake and cut/fill zones.

6

Estimation

Chapter-wise BOQ built automatically: clearing, earthwork, pavement, drains, structures, road furniture. Source-level breakdown per item.

7

Pricing

Rate analysis against MoRTH SDB 2019. Full build-up: labour + machinery + material + OH + profit. NHAI 8-level cost cascade to Grand Total.

8

Export

Chapter-wise BOQ to Excel. Cover abstract, DOQ, per-structure matrix. Pre-bid validation flags missing rates and below-cost items before you submit.

What the estimator can do

Built for NHAI, NHIDCL, MoRTH, and state PWD tenders. Every feature designed around the documents Indian road contractors actually use.

BOQ from geometry, not from memory

Upload your cross-section drawings. CivilBolt reads the widths, layers, and slopes and computes every quantity, from clearing and earthwork to GSB, WMM, DBM, and BC. Nothing typed from memory.

MoRTH rates built in

Standard items arrive with a full rate build-up, labour, machinery, material, overhead, and profit, each citing its MoRTH clause. No rate book to maintain in Excel.

Cost cascade to Grand Total

Terrain premium, contingencies, escalation, GST, and cess cascade from the civil total to the Grand Total. Edit any rate and the cover abstract recalculates.

Interactive mass haul

Drag balance points on the mass-haul diagram and watch the haul cost move live, from ₹117 Cr down to ₹52 Cr as you retune the cut and fill.

3D corridor preview

See the road in 3D, the pavement layer-cake, bridges, and cut/fill zones by chainage, with a drive-through view along the alignment.

Pre-bid checks before you submit

The export screen flags missing rates, below-cost items, and rates that stray from MoRTH norms, so errors are caught before the bid goes out.

HAM and EPC cashflow

An S-curve cashflow across the construction window. Switch to HAM for milestone payments and annuities, with a financier overlay showing peak debt.

Scenarios you can compare

Save a bid, clone it, and adjust materials or equipment. What-if sliders update the total, and every scenario sits side by side for comparison.
