When you’re working with existing buildings, accuracy matters. Our team focuses on capturing what truly exists on site and turning that information into clear, usable documentation. The result is fewer assumptions, smoother planning and greater confidence at every stage of your project.
As-built documentation requirements can vary from project to project. Factors such as building size, layout complexity, level of detail and deliverables all affect pricing and turnaround time. The information below is intended to help you understand how estimates are generated before final project review.

As-built drawings provide an accurate record of existing building conditions based on real on-site measurements. They are essential for renovation planning, design coordination, permitting preparation and avoiding costly surprises during construction.
Original drawings often differ from what was actually built due to field changes, renovations or undocumented modifications over time. As-built drawings reflect the current, real-world conditions of the property not assumptions.
As-built drawings are commonly needed before renovations, remodels, additions, tenant improvements or design updates. They are also useful when documentation is missing or outdated.
Our as-built drawings may include floor plans, dimensions, wall layouts, doors and windows, ceiling heights and other architectural elements. The level of detail depends on the project scope and selected deliverables.
We capture existing conditions through on-site measurements and, when required, 3D scanning and digital measuring tools. All drawings are created from verified field data to ensure accuracy.
We provide clean, accurate DWG and Revit-ready as-built documentation that integrates smoothly into design workflows. Our drawings give architects and designers a reliable foundation to work from.
