Project Overview

Project Summary

Reality IMT performed high-definition 3D laser scanning of the interior, exterior, roof, and parking lot to produce existing condition drawings in CAD and Revit for a multi-level office building in Houston, Texas. The building required major upgrades, but there were no record drawings or correct drawings available. The owner and architect needed accurate architectural drawings to kick off the design project and apply for permits.

Reality IMT was chosen because of its vast experience with documenting existing office buildings without disrupting day-to-day operations. Fast turnaround time motivated the owner to hire Reality IMT because time was of the essence. The fee was also very reasonable for the scope of work.

Client Need

Project Challenge

The multi-level office building needed major upgrades, but there were no record drawings or correct drawings available. The owner and architect needed accurate architectural drawings to kick off the design project and apply for permits. The project required fast turnaround, accurate measurements, and minimal disruption to occupied office spaces.

Access / Coordination

Occupied offices made it challenging to coordinate access. Since time was of the essence, scanning was performed after hours to minimize disruption.

Technical Documentation

The project required comprehensive documentation of interior, exterior, roof, and parking lot conditions across a 70,000 SF multi-level office building.

Schedule / Business Constraint

Fast turnaround time was critical to kick off the design project and apply for permits. The fee needed to be reasonable for the scope of work.

Reality IMT’s Approach

Occupied Building Capture and Permit-Ready Deliverables

Reality IMT structured the work to document the full office building while maintaining day-to-day operations and delivering accurate drawings on a tight schedule.

Planning & Scope Alignment

A detailed schedule was developed to perform after-hours scanning across interior, exterior, roof, and parking lot areas without disrupting occupied office operations.

Field Capture

High-definition 3D laser scanning captured the full building interior, exterior elevations, roof conditions, and parking lot layout for comprehensive as-built documentation.

Processing & QA/QC

Point cloud data was processed and quality-checked to ensure accurate geometry for architectural modeling, BOMA area verification, and permit-ready drawings.

Deliverable Production

Architectural as-built Revit LOD 300 with BOMA calculations was produced, along with CAD drawings and PDF sheets for design coordination and permit application.

Permit-Ready Documentation

A coordinated as-built package that enabled the owner and architect to kick off the design project and apply for building permits.

Project Outcome

Accurate As-Built Drawings for Design Kickoff and Permit Application

The completed documentation provided the owner and architect with accurate architectural drawings that replaced missing or incorrect record drawings. The as-built Revit LOD 300 model, CAD drawings, and BOMA area calculations enabled the design project to begin and supported the permit application process.

The after-hours scanning approach minimized disruption to occupied offices, while the fast turnaround and reasonable fee kept the project on schedule and within budget.
