Project Overview

Project Summary

Reality IMT provided high-definition 3D laser scanning and architectural as-built documentation for a vacant office building at 10555 Richmond Avenue in Houston, Texas. The project covered approximately 50,000 square feet and included field scanning, post-processing, and Revit/PDF as-built deliverables.

The scope included floor plan documentation, reflected ceiling plan features, visible structural/framing information, and selected electrical plan items. Reality IMT documented doors, windows, demising walls, exposed columns, shafts, stairwells, plumbing fixtures, ceiling support beams, vents, electrical devices, panels, light fixtures, and visible ceiling/roof framing.

Client Need

Project Challenge

GSA Architects working with TXDOT needed reliable existing-condition documentation to support architectural planning, renovation design, or tenant improvement work for the vacant office building. Since the requested scope included floor plans, reflected ceiling plans, wall documentation, and structural/ceiling/roof framing information, the client needed a dependable base model before beginning design work.

The goal was to replace incomplete, outdated, or unavailable drawings with a current Revit and PDF as-built package that the design team could use for planning and coordination.

Access / Coordination

The building had no power and ceiling tiles needed to be removed to uncover the plenum space elements required for as-built documentation.

Technical Documentation

The project required documentation of floor plans, reflected ceiling plans, visible structural/framing, and selected electrical items across a 4-story, 50,000 SF office building.

Schedule / Business Constraint

Reality IMT coordinated with the contractor — Harvey Builders — to ensure enough access was given to document the ceiling at every level of this 4-story building.

Reality IMT’s Approach

High-Definition Capture and Design-Ready Deliverables

Reality IMT structured the work to capture the full building using high-definition 3D laser scanning and convert the data into a Revit 2019 as-built model within three weeks of PO or signed agreement.

Planning & Scope Alignment

Reality IMT coordinated with Harvey Builders to plan ceiling tile removal and access at every level of the 4-story building, ensuring all plenum space elements could be documented.

Field Capture

High-definition 3D laser scanning captured the full 50,000 SF building, including floor plan elements, reflected ceiling plan features, visible structural/framing, and selected electrical items.

Processing & QA/QC

The collected laser scan measurements were processed before modeling, with QA/QC performed to verify accurate geometry for all documented features.

Deliverable Production

A Revit 2019 as-built model was developed from the point cloud, with PDF drawing sheets covering floor plans, reflected ceiling plans, walls, structural elements, and electrical features.

Project Outputs

Deliverables Provided

The deliverables below reflect the archived project information and should be matched with project-specific images before publication.

Point Cloud

Registered 3D laser scan data capturing the full architectural and structural conditions of the 50,000 SF office building.

CAD Drawings

AutoCAD DWG files with floor plans, reflected ceiling plans, and selected electrical plan documentation.

PDF Drawing Sheets

Sheet-based PDF deliverables organized by floor and discipline, including floor plans, RCPs, roof plan, and structural documentation.

Floor Plans

Detailed floor plans documenting doors, windows, demising walls, exposed columns, shafts, stairwells, plumbing fixtures, and millwork.

Reflected Ceiling Plan

RCP documenting exposed support beams, vents, equipment, and visible ceiling/roof framing conditions.

Roof Plan

Documented roof geometry and visible structural conditions for renovation coordination and design planning.

Project Outcome

A Current Revit and PDF As-Built Package for Government Renovation Design

The completed documentation provided GSA Architects and TXDOT with a dependable, current Revit and PDF as-built package that replaced incomplete, outdated, or unavailable drawings. The deliverables supported architectural planning, renovation design, and tenant improvement work for the vacant office building.

The field-verified model and drawing sheets gave the design team a reliable base for planning and coordination, reducing the risk of design errors and field surprises during construction.
