icon Mechanical served as the Design Assist Mechanical Contractor for the BJH North Penthouse. The newly constructed twelve story hospital included an additional two story Penthouse which would be built as a turnkey project.
This project demonstrates the ability of owners, engineers and contractors to build differently and outside the box. Conceptual design of the core hospital systems were developed early in the project and bid as a prefabricated Penthouse. This would allow contractors the ability to develop and build a plan to build the Penthouse a year before the roof of the building would be constructed.
All systems constructed in the Penthouse starting from design through construction were the responsibility of icon Mechanical. This would include structural, concrete, drywall, electrical, plumbing and mechanical installation.
As the design assist contractor, icon was responsible for generating the construction documents and running the BIM process with all trades for the Penthouse. The last area of the building to be constructed was the first to have completed design which would lend itself to save much needed schedule time for fabricating the mechanical systems.
All the major systems would be fabricated in modules months before needed. A total of 8 pumps skids weighing as much as 30,000 lbs each were shop fabricated as well as over 20 pipe racks and modules weighing in some cases over 30,000 lbs and 70’ long. All of the chillers, boilers, pumps and pipe racks would be set in place in a couple weeks so that only final connections to equipment would be necessary. Total time to construct the Penthouse and have chilled water online was 6 months. This method would be the only way to construct this Penthouse in that time period.
One interesting building strategy for this Penthouse is that the equipment and pipe skids would be set before the Penthouse building is erected. This allowed much needed speed in setting mechanical items directly were they were located. The building could then be built around the equipment as opposed to typical building construction where the equipment would be after the building construction.
