Service / Preconstruction

Preconstruction & estimating

Turn available plans and specifications into a more organized view of project scope, quantities and cost considerations.

Support for early project decisions

Estimate inputs depend on document quality, project stage, location and requested detail. OPUS confirms assumptions and deliverables with the client before work begins.

Scope and plan review

Review project information to clarify available documents, scope boundaries and questions that may affect pricing.

Quantity & material takeoffs

Measure and organize quantities from provided drawings and specifications as agreed for the project.

Cost estimate support

Prepare cost information and estimate documentation using agreed assumptions and client-provided or otherwise confirmed inputs.

Typical workflow

Share the project documents, confirm scope and format, review assumptions, then receive the agreed estimate or takeoff deliverable for discussion.

  1. Understand project scope, location and decision needs.
  2. Review drawings, specifications and requested breakdown.
  3. Confirm assumptions, exclusions and deliverable format.
  4. Prepare the agreed takeoff or estimate and coordinate questions.

Estimates and takeoffs are planning and bid-support documents, not guarantees of final construction cost. Results depend on the scope, source information, assumptions and market inputs provided or confirmed for each project.
