Preconstruction Services in the USA

US contractors are bidding more work than their offices can measure, model and price, and good estimators and BIM staff are hard to hire. Optimar Precon provides preconstruction services in the USA: CAD drawings, BIM models, takeoffs and estimates from a dedicated offshore team, managed from our Dallas office, so your people can stay focused on winning and building the work.

  • Drawings sent at the end of your day are worked on overnight
  • Per-project fixed fees or a dedicated team on a monthly rate
  • Work to US codes, CSI MasterFormat and your own templates

How US firms use us

A Second Shift for Your Preconstruction Team

Our production team works while US offices are closed. Send drawings in the afternoon and quantities, models or marked-up sheets can be waiting the next morning. Some clients send one bid at a time; others keep a dedicated estimator, drafter or BIM modeler working only for them, month after month.

FAQs

Preconstruction Services in the USA: FAQs

Do you have an office in the USA?

Yes. Our US office is in Dallas, Texas, and handles contracts, calls and account management. Production is done by our team in New Delhi, which works while US offices are closed.

Which states do you work in?

All 50. We have state pages for many of them, but we work from drawings and specifications, so a project’s location doesn’t limit what we can do.

Do you follow US codes and estimating formats?

Yes. Estimates are organized by CSI MasterFormat divisions or your own format, and drawings and models follow the codes and standards named in your project documents.

Can we hire a dedicated estimator or drafter?

Yes. You can book a full-time remote estimator, drafter or BIM modeler on a monthly rate, working only on your projects and to your standards.
