Home / Services / As-Built Drawings
When existing drawings are unavailable, inaccurate, or simply do not exist, we field-verify the building and produce complete, accurately documented drawings — ready for your design team, architect, or building department.
Every as-built engagement begins with a field visit to verify existing conditions — and ends with a complete, accurately drafted set of drawings your design team can rely on.
Our team visits the property and performs comprehensive field measurements of the existing building — room dimensions, ceiling heights, wall locations, structural elements, and MEP systems as required by the scope.
Floor plans, elevations, building sections, roof plans, and site plans — drawn to scale and dimensioned from field measurements, reflecting the actual existing conditions of the building.
Existing foundation layout, framing plans, beam and column locations, and structural member sizes — field-verified and documented for use in renovation design, structural analysis, or permit applications.
Existing mechanical, electrical, and plumbing system documentation — including ductwork routing, electrical panel locations and circuits, plumbing fixture and drain locations, and equipment identification.
Field measurements are drafted in AutoCAD — floor plans, elevations, sections, and site plans — then reviewed against field notes for dimensional accuracy before delivery.
Completed drawings are delivered in AutoCAD DWG format for your design team and PDF format for your records or building department use — formatted to standard sheet sizes.
If the as-built drawings are being produced as the first step in a renovation or addition project, we coordinate the record documents with your architect and design team so they have an accurate base from which to design.
If field conditions are discovered during construction that differ from the as-built documents, we update the drawings to reflect actual conditions — maintaining an accurate record set throughout the project.
Share your project details and we will respond with a detailed fee proposal and delivery timeline within 24 hours.
We produce as-built drawings for a wide range of situations — whenever an accurate record of existing conditions is needed before design, permitting, or a transaction can move forward.
When no drawings exist for an existing home, we field-verify and document the structure before your architect begins renovation design — giving the design team an accurate base to work from.
As-built drawings required for commercial real estate due diligence — providing buyers, lenders, and tenants with accurate building documentation before a transaction closes.
Building departments require existing condition drawings before approving additions, changes of use, or tenant improvements. We produce the as-built set required to initiate the permit process.
For older buildings where original drawings are lost or unavailable, we reconstruct the existing conditions from field observation — producing a complete, accurate record of the building as it stands.
Landlords and tenants need accurate base plans of existing shell conditions before tenant improvement design can begin. We provide field-verified floor plans and reflected ceiling plans for TI projects.
Accurate, field-verified building documentation for insurance claims, construction defect proceedings, or legal matters requiring a reliable record of existing conditions.
Every as-built drawing set we produce is field-verified from on-site measurements, drafted to scale in AutoCAD, and delivered in both DWG and PDF format — ready for your architect, design team, or building department.

DWG Base File Delivered to Your Design Team
Because structural, MEP, and architectural as-built documentation are all in-house, we can capture all three disciplines in a single field visit — reducing disruption to building occupants and cutting overall project time.
Our drawings come directly from careful on-site field measurements — dimensioned, drafted to scale, and delivered in a format your architect or design team can work from immediately.
For most as-built projects, we can prepare a preliminary fee proposal from the property address and a brief description of the building — without requiring a site visit or additional information upfront. This gets your project moving faster.
Many as-built engagements are the first step in a renovation, addition, or change of use. When that is the scope, we continue as the engineer of record for the new work — eliminating the transition cost and delay of bringing in a separate engineering team after the record drawings are complete.
Once as-builts are complete, we can continue as the structural engineer of record for your renovation, addition, or new construction scope.
MEP as-built documentation followed by new MEP design for renovations and tenant improvements — handled by the same in-house team.
Civil site documentation and as-built survey coordination for properties requiring accurate existing site conditions before new civil design begins.
As-built drawings are field documentation that records a building as it actually exists — not as it was originally designed. You need them when the original drawings are unavailable or inaccurate, when a building department requires existing conditions documentation before approving a permit, when you are buying or selling a commercial property and need accurate records, or when your design team needs a reliable base from which to design a renovation.
We begin with a field visit to the property. Our team measures the existing building — room dimensions, wall locations, ceiling heights, structural elements, and MEP systems — depending on the scope required. We then produce the drawings in AutoCAD and review them against our field notes before delivery.
As-built drawings are field measurement documents — they record existing conditions, not new engineering work. For most uses including renovation planning, design base plans, and property transactions, accurate field drawings are all you need. If a specific permit submission requires an engineer of record on a related document, that is a separate scope we can advise on based on your jurisdiction and project type.
Timeline depends on building size and the scope of disciplines required. A single-family residential as-built typically takes 1–2 weeks from field visit to final deliverable. Larger commercial buildings with full architectural, structural, and MEP documentation take longer. Every fee proposal includes a specific delivery date.
Yes, and this is often the most efficient path. When we produce the as-built drawings and then continue as the engineer of record for the renovation or addition, there is no transition between teams — we already know the building and can move directly into design. We can scope both phases together or separately depending on your project timeline.
Share the property address and building type. We can typically scope an as-built project from that information alone and respond with a fee proposal within 24 hours.
