BIM and CAD Services in Washington, DC
Much of the work in Washington now starts with an existing building: an empty office block being turned into apartments, a federal building being upgraded. Before anyone can design the new layout, someone has to model what is already there. Optimar Precon provides Revit BIM modeling and CAD services in Washington, DC, from existing-conditions models to coordinated construction drawings.
- Scan-to-BIM and as-built models of existing buildings
- Revit models for architecture, structure and MEP
- CAD drafting and conversion of old paper and PDF drawings

A City Rebuilding Itself From the Inside
With so much office space sitting empty, DC’s existing buildings have become its main construction pipeline. That changes what design and construction teams need first.
Office-to-residential
Older office floors replanned as apartments, needing accurate existing models before unit layouts.
Federal and institutional
Upgrades to government and institutional buildings with limited or outdated record drawings.
Tenant fit-outs
New layouts and services threaded through existing slabs, shafts and ceilings.
Historic buildings
Existing fabric documented carefully so new work fits around it.
Existing Buildings Need Accurate Models First
A conversion lives or dies on what is behind the walls: column grids, slab edges, shafts and risers that may not match the 1970s drawings. We turn point clouds, surveys and old drawings into Revit models and CAD backgrounds your design team can trust, then keep them current as the design develops.
From point cloud to Revit
Scans from your surveyor modeled to the level of detail you need.
Legacy drawings rescued
Paper and PDF archives redrawn as editable CAD.
New services coordinated
Risers, ducts and plumbing for new units checked against the structure.
