eTAB Works-Estimator™ carries an engineering work through every stage of its file: preliminary estimate, detailed estimate with full analysis of rates, DNIT and standard bidding documents, the agreement, running-account and final bills, and escalation claims at the end — with each stage reading its figures from the stage before it, so nothing is re-typed and nothing quietly drifts.
Estimotor also hosts free estimating resources — quantity calculators, material-consumption norms, an IS-code directory and escalation indices — open to every engineer, no sign-in needed.
What the name stands for
Accurate Estimates · Fair Tenders · Timely Bills
What comes with the software, beyond the software.
Your work stays yours — simple project backup and restore, with support from people who know works estimation.
Your organisation's name and logo on every report, your own schedules of rates, your office's registers and formats.
The web edition is always the latest version; desktop updates install over the old one without touching your projects.
Screens that follow the works file — estimate, DNIT, agreement, bill — the way an engineering office actually thinks.
Run standalone on one PC, or as organisation accounts on the web with per-user sign-in, seats and a single editor per project.
No account, no charge — quick checks you can trust while the file is open on your desk.
Concrete, brickwork, steel, earthwork, flooring & paint, and unit converters — each with the working shown, so you can defend the figure in a check-measurement.
Open calculators →Per-unit cement, sand, aggregate and steel norms for the common items of work — the numbers you reach for when framing a theoretical-consumption statement.
See the norms →The Indian Standards an estimator actually cites — materials, concrete, steel, masonry, safety — grouped by subject with a line on what each one governs.
Browse the directory →How cost indices and price-variation clauses work, with worked examples of Clause 10C, 10CA and 10CC claims and where each figure comes from.
Study escalation →Working notes from the estimator's chair — preparing a detailed estimate, building a rate analysis, passing an RA bill, handling deviations.
Read the articles →Printable measurement-sheet and bill-checking proformas, CSV templates, and the desktop-edition installer request — all in one place.
Get the downloads →One data spine from sanction to final payment. Each module hands its output to the next.
Plinth-area based costing with services and development charges, brought to current level through the cost index — a sanction-ready PE without a spreadsheet.
Open in app →Items picked from the schedule of rates, quantities entered as details of measurement, and the abstract of cost assembling itself as you work.
Open in app →Rate build-up from labour, material and machinery basics — for schedule items, market-rate justification and non-schedule items alike.
Open in app →Notice inviting tender, Schedule 'F', earnest money and the standard bidding document, all generated from the approved estimate — plus the e-procurement BoQ.
Open in app →The tendered premium or rebate is applied once and locked; agreement rates then flow into every bill, so the contract is quoted, never re-typed.
Open in app →Running-account bills with measurements, part-rate payments, extra and substitute items, deviation statements, secured advance and material recovery.
Open in app →Clause 10C labour, 10CA specified-material and 10CC index-based claims, computed from the bills already recorded — not from a side spreadsheet.
How escalation works →Agreement, bill and service-order registers with a document library and the full set of office reports, kept alongside the works themselves.
Open in app →Desktop and web run the same estimating core — the same work gives the same paisa on both.
Every statement is generated from the recorded data and exports to PDF and Excel under your organisation's letterhead and logo.
Whether you are one engineer preparing estimates or a department moving its whole works cycle online, write to us — we will walk you through a live work on your own schedule of rates, from preliminary estimate to a running bill.
