Revit BIM Model for Residential Build
Budget: €8 – €30 EUR
1. PROJECT GOAL
The goal of this project is to create a fully detailed BIM model of a residential building, based on existing documentation, with major structural design changes, and expanded to include all construction layers, engineering systems, site works, quantities, and load calculations.
The final BIM model must allow the client to:
Build the house independently without missing information
Extract accurate quantities for all construction stages
Filter the model by construction phases, trades, and systems
Modify materials and solutions later without redrawing
Use the model as a long-term reference for construction, maintenance, and upgrades
The BIM model will be the primary and authoritative project document.
