Model authoring
Renga, nanoCAD BIM, Model Studio CS. There's no direct Revit replacement, so selection depends on object type and project discipline, not a universal checklist.
Common data environment (CDE)
Vitro-CAD, Pilot-BIM, Exon, SIGNAL DOCS, Sarex. This is where model versions, remarks and approvals live; value emerges when the Common Data Environment feeds into schedules, procurement and as-built documentation.
Larix.EST, Tangl Value. They calculate volumes from the model and rebuild schedules with changes. We don't implement these products—we deliver their data into the estimate and accounting system, and our AI estimator prepares the draft budget.
Estimates
GRAND-Estimate, 1C:Estimate TIM CORP. The estimate system connects to scope of work and subcontracts: this is the most common point of manual data transfer.
Tenders and Procurement
Tender platforms, bidder cost estimates and contractor work lots. Value emerges when lots are composed from estimate items and bidding results feed back into contracts, delivery schedules and plan-vs-actual tracking.
Accounting system
1C:ERP Construction organization management. Contracts, closing documents, payments and project cost; actual data from the site should flow here, not just paid invoices.
Project Financial Model
Financial codifier, cost elements and project financial model. Estimates should arrive already broken down by cost item, not as a summary that the finance manager manually assembles at period end.
Seven software categories, comparison tables and each product's limits — in our review 'Construction and BIM software in CIS 2026'.
