B&I works with a wide range of owners, businesses, construction managers, and municipalities. Each of these units will require MEP services that are outside the range of normal “plan & spec” construction.
The building solutions department (BSD) will function to meet these needs, which in many cases, will result in a construction project that will be delivered to either the construction department or the service group. The BSD group is a unique MEP service to Southwest Florida.
DEPARTMENT
The building solutions team provides engineered signed and sealed reports, plans, and energy studies. These services will be a direct result of personal interaction with clients, and will be developed through site meetings and schematic plan review. BSD has a team of engineering graduates, and CAD specialists that provide support with cooling/heating load calculations, energy compliance, ventilation rates, and schematic HVAC design.

Building Information Modeling (BIM) is a process involving the generation and management of digital representations of physical and functional characteristics of places.
BIM is changing how buildings, infrastructure and utilities are planned, designed, built and managed. BIM solutions help turn information into insight and deliver business value at every step in the process.
Some of the benefits of using BIM are optimized planning, controlled costs and improved efficiencies. There are also advantages by modeling and visually walking through the building. You can foresee problems before they happen. Leave it to B & I to streamline planning and design to deliver a higher quality project on time!
THE ADVANTAGES OF
B & I’s president and vice president are both Leadership in Energy and Environmental Design (LEED) certified.
