IMPROVED SPACE MANAGEMENT
By understanding the details of how space is used, facility professionals can reduce vacancy and ultimately achieve major reductions in real estate expenses. The room and area information in BIM models are the foundation for good space management.
The key challenge in developing a maintenance program is entering the product and asset information required for preventive maintenance. The information about building equipment stored in BIM models can eliminate months of effort to accurately populate maintenance systems.
EFFICIENT USE OF ENERGY
BIM can help facilitate the analysis and comparisons of various energy alternatives to help facility managers dramatically reduce environmental impacts and operating costs. By analyzing the costs and the savings of various facility improvements and building system retrofits, facility managers gain a tool to optimize building performance over the life of the building.
ECONOMICAL RETROFITS AND RENOVATIONS
A “living” BIM model provides an easier means of representing three-dimensional aspects of the building. Better information about existing conditions reduces the cost and complexity of building renovation and retrofit projects. By providing more accurate and dependable information to contractors, change orders resulting from “surprises” in as-built conditions can be greatly reduced.
ENHANCED LIFECYCLE MANAGEMENT
Some building design professionals are embedding data on life expectancy and replacement costs in BIM models, thereby helping an owner understand benefits of investing in materials and systems that may cost more initially but have a better payback over the life of the building. For example, using vinyl wall covering for interior wall finishes is more expensive than paint initially, but may result in reduced overall lifecycle costs since it is more durable. The lifecycle data is also very valuable for forecasting ongoing capital improvement costs.
