Project Overview

Client Profile

Building Survey Company

Location

USA

Industry

Design, construction, and management solutions

Inputs

Point cloud data drawings, scans, and 360 ° photos derived from drones and laser scanners

Deliverables

As-Built Revit model, final PDF files with elevations, floor plans, ceiling plans, cover sheets, etc.

Business Needs

A leading surveying company located in the US contacted the team at Hitech CADD services to build a coordinated As-Built model for its client. The business needs were primarily directed towards improved facilities management based on a single collaborative model of existing construction.

Challenges

Voluminous scanned data (i.e. gigabytes of data) with greater redundancy based on scans from multiple angles
Inferior scan quality of various construction areas and interior spaces
Higher modeling hazards based on improper scanning leading to greater time consumption

Our Solutions and Approach

Created Point cloud to BIM as-Built 3D Revit model with elevations, floor plans, ceiling plans, cover sheets for a US-based retail snacks and coffee outlet.

Share Your Thoughts

An accurate As-Built 3D model with 10mm accuracy was developed within 112 days based on point cloud data. Other deliverables included a complete PDF file with floor plans, building sections, elevations, site plans, roof plans, and more.

Our Revit engineering team collated all the .rcs point cloud files sent by the client and cleaned up unnecessary duplicates
On the basis of the inputs provided by the client, proposed dimensions were assumed for scans with low density and the 3D model was built and sent to the client for approval
Various floor plans, site plans, elevations, sections, and other deliverables were built based on the model
Based on various project parameters, internal and external QC teams performed a complete Revit file audit to verify content integrity and quality
The Revit files were checked to ensure that all quality standards are met

Client Deliverables: An accurate As-Built 3D model with 10mm accuracy was developed within 112 days from point cloud data. Other deliverables included a complete set of drawings with floor plans, building sections, site plans, roof plans, and more.

Business Impact

Revit model and as-built drawings delivered before the planned schedule
+/- 10mm accuracy helped client assess the state of the building in a collaborative setup
