About Estimotor

The name

The name reads straight off the work it serves. Estimotor stands for Estimating, Schedules of Rates, Tendering, Item Analysis and Measurement; the rest carries it through to Oversight, Transparency, Online working and Reporting — so estimotor.online spells the promise letter for letter. Above all of it sits one purpose: figures that hold up — an estimate that tallies, a tender that is fair to both sides, and a bill that is paid on time. eTAB Works-Estimator™ is the software through which Estimotor does the estimating-to-billing part of that work.

Where this began

This work grew out of years spent at the estimating desk of Indian engineering offices — preparing detailed estimates line by line, building up rates from a schedule of rates, framing DNITs, drawing agreements and then carrying the same work through measurement books and running-account bills to final settlement. Anyone who has sat at that desk knows the routine: the abstract of cost that must tally to the paisa, the analysis of rates that a scrutinising hand will re-work, the deviation statement that has to explain itself, the recovery for departmental material that must not be missed on the last bill.

Most of that arithmetic is honest, repetitive and unforgiving. Done by hand it eats weeks; done in loose spreadsheets it drifts — a rate copied wrong here, a rounding difference there, an abstract that no longer agrees with its details of measurement. eTAB Works-Estimator™ began as a set of tools written to remove that drudgery from one desk, and it grew, revision by revision, into a full estimation-to-billing platform because each stage of the works cycle kept asking for the next: the estimate wanted a DNIT, the DNIT wanted an agreement, the agreement wanted RA bills, and the bills wanted escalation, deviation and material recovery handled the way a works office actually handles them.

The result is software shaped by procedure rather than by fashion. It follows the sequence a works office follows, keeps every figure traceable back to its source entry, and prints the statements in the form an auditor expects to see.

One computation core, two editions

Everything runs on a single computation core — one set of rules for analysis of rates, quantity roll-ups, premium and rebate, bill deductions, escalation and recoveries. The desktop edition and the web edition are two front doors to that same core, so a figure worked out in one edition matches the other to the last decimal. There is no "web version arithmetic" and no "desktop version arithmetic"; there is one arithmetic.

Long before any software, every estimator carried a pocketbook of constants — dry-volume factors, bricks per cubic metre, steel weight per metre, cement per bag. Those quick figures are how an experienced hand smells out an error: a plaster quantity that looks fat, a steel weight that cannot be right, a cement consumption that does not square with the mix. The free pages here are that pocketbook, put online: calculators for the common items, consumption norms, an IS-code directory arranged by number, and the escalation indices an RA-bill claim leans on.

They are meant for quick checks at the desk or on site, for teaching a junior how a figure is built up, and for sanity-testing a rate before it goes into an estimate. They are deliberately not a substitute for your organisation's schedule of rates or for the governing IS codes — those remain the authority, and every reference page here says so plainly.
