This fragmented input required significant interpretation and data enhancement to produce a complete model.
Project Objective
To develop accurate as-built BIM models for multiple single-family residences to facilitate renovation, refurbishment and future planning. The objective included capturing all existing conditions with high fidelity, consolidating fragmented client inputs and delivering a coordinated architectural and structural model that supports design and construction decision-making.
Scope of Work
01
Creation of an Existing-Conditions BIM Model for each unit
02
Mapping and recording all possible architectural and structural details
03
Development of comprehensive base drawings including plans and elevations
04
Integration of supplemental site and surrounding context data
Client Input
The client provided limited existing information consisting of
- Scanned images
- Hand-drawn sketches
- Photographs of the units
- PDF files and CAD drawings
Project Description
The engagement involved modeling multiple single-family residential units where the primary goal was to create accurate as-built BIM models despite minimal and incomplete source data. Each property required detailed mapping of existing architectural and structural elements to support upcoming renovation work.
Due to limited client-provided documentation, our team leveraged Google Street View, satellite imagery and contextual site information to bridge data gaps. This enabled us to align exterior conditions, roof forms, façade details and surrounding structures with a high degree of precision.
Our BIM specialists applied advanced analytical methods, custom algorithms, and standardized modeling workflows to ensure rapid and consistent delivery. A set of predefined project templates was developed based on recurring building typologies, significantly optimizing efficiency and accuracy. With this streamlined process, our team successfully delivered each unit within one working day, maintaining high quality across all models.
