Design and Functional Components
This building is designed to hold the head office (in red) and three extra storage wing spaces (in blue) for Basement Systems, Inc. The center core of the building consists of a 3 story office building with a small mezzanine on top. The office building has an engaging 4 story glass elevator and stair tower located in the front of the building. In addition, the office building holds a 4,500 square foot training and meeting presentation room located on the third floor. Three wings branch off the main office in the North, East, and South direction. These three wings act as warehouses for extra storage the company needs. The layout of the building does a great job at only capturing the main office building and hiding the use of the three warehouses from the street view.

Building Facades
The building façade of the three storage and warehouse buildings are pre-engineered metal buildings having white split face concrete masonry units around the overhead doors and a white vertical metal panel system above. Each wing has a white eight foot canopy hanging over the overhead doors. The main office building has a more detailed building façade. The office’s façade consists of blue Pac-Clad horizontal fluted metal panels with details of white Alucobond. The exterior windows will be fixed aluminum framed and 1” clear tempered low e insulated glass being tinted gray with spandrel glass matching. The large amount of windows around the main office building allows for great natural light to shine within the building.
Roofing
Due to the different building structures two different roofing systems are used. Each of the three storage wings possess a roofing system of MR-24 standing seam roof by Butler. The roofing structure on the center office building is a .060 EPDM fully adhered to 6” rigid insulation.
Sustainability Features
The central stair and elevator tower act as a bright atrium bringing light into the building along with the other storefront windows. These will help lower the use of artificial lighting inside the building. The current building site was able to access and use the soil from the neighboring construction project that was completed a year before.
PART II
Construction
Basement Systems Inc. (BSI) owns multiple lots of land in the Industrial Park located in Seymour, CT. They have been expanding their company rapidly, which is the reason for developing Basement Systems Inc. – 33 Progress. The project delivery method for this project is Design-Build. Claris Construction has done multiple projects in the past for BSI, so BSI decided to use Claris again for their in-house architects to develop designs and in-house personnel to manage the overall project. Besides Claris, several other engineering consultants and design firms have been involved early on in the design process. The contract between the owner and Claris Construction is a Cost-Plus “open book” contract. All subcontracted work was bid out and contracted on a standard lump sum contract based on scopes of work.
The construction site consists of a large area with minimal constraints from surrounding buildings or roadways. With the large site, there are plenty of spaces for laydown areas and storing materials to minimize delays. With that being said, steel for each building was delivered and stored onsite prior to the start of the erection for each specific building. To erect the building structure, a lull lift was used to set the steel in place. The only challenging aspect of the site is the slope, a declined grade change from West to East. Due to the sloped site, the construction of a retaining wall was needed as part of the foundation. The overall project was organized into four main phases, a phase for each building. The phases progress from South to North starting with Building 1 and working through Building 2, Building 4, and finally Building 3.
Electrical System
The electrical system starts at the pad mounted transformer that goes into the main entrance and C.T. switch at 1200A and feeds into twelve panels. The main electrical room is located in Building 1 and is on the lowest level of all buildings. The electrical room supports the lighting, receptacles, and other equipment that require electricity. The first floor has six panel with voltages of 120/208 and 277/480. In the second floor there are two panels one with a voltage of 120/208 and another with a voltage of 277/480. On the third floor there are four panels, two with a voltage of 120/208 and the other two with a voltage of 277/480. The minimum size of wire for any circuit is #12 A.W. Gauge insulated with THHN Type- MC Cable or ¾” c.
Lighting System
All lighting in the warehouse buildings are pendant mounted LED lights with 16,000 lumens and standard distribution with aircraft cable. The same light fixtures will be used in the production rooms with 12,000 lumens. All offices, conference rooms, and kitchen will have 2’x2’ recessed LED lights with diffuse lens and except use of 4,500 lumens. All hallways and bathrooms will have 6” recessed LED downlight, 277 volt ballast and 1,500 lumens. 40’ linear LED pendant light with 277 volt dimming drivers are used in the training/meeting room. In addition, the stage area uses 6” recessed LED down lighting with 4’ LED pendant light with frosted lenses.
Mechanical System
There are no specific mechanical rooms. All the mechanical equipment is located on the roof of the core building and the two North and South wing. There are six Air Handler Units and one Makeup Air Unit that supply the entire core building. Variable air volume terminals are located throughout the building to ensure the right thermal comfort desired by the occupants. There are a total of eleven heat pump condensing units located on the North and South wings. In each of the three wings there are four gas fired unit heaters. There are several exhaust fans throughout the building and one main exhaust fan from the kitchen.
Structural System
This building consists of four different steel framing systems. All the steel structures are connected on concrete footings with anchor bolts and base plates. The three storage wings are all individual pre-engineered Butler steel. These structures are one story tall and have several portal frame lines that create an open floor plan. The center office building is a conventional steel structure with elevated concrete slabs on composite steel floor decking. The main column sizes used are: HSS5x5x1/2, HSS6x6x1/4, HSS8x8x1/2, and W10x33. In the steel structure used a joist system with 24K7 joists. The main beam used for this building are: W16x26, W12x26, and W14x22. The steel was erected using large lulls that moved around the site and unloaded straight from the truck or the material laydown areas.
The foundations for this project are comprised of multiple concrete footings and one mat foundation. There is a 5” slab on grade for all the buildings with #5 rebar. A 16” wide concrete retaining and foundation wall was formed and poured in the West face of the building. Plywood was used for all formwork of footings and mat foundation. Engineered formwork was used for the main retaining wall.
Fire Protection
In Building 4, there windows that overlook into each warehouse. A 90 min. fire shutter system is placed above the windows to help separate the buildings and contain the fire. Piping for all buildings are to be hydrostatically tested at not less than 200psi for 2 hours, or at 50psi in excess of the maximum pressure, when the maximum pressure to be maintained is in excess of 150psi. The overall sprinkler system is a wet sprinkler system. There are a total of 89 sprinklers spread around the building. Fire alarms, smoke detection, and portable fire extinguishers are all included in the system.
Transportation
Workers and visitors of the building will enter the on the South/West entrance of Building 4. The main egress in the building is an elevator and grand stair system. The elevator is a three stop glass LULA Hydraulic elevator. The grand stair to all floors is a concrete filled tread steel pan stair system with open risers. Secondary egress and emergency egress is located on the North and South sides of the building.
Telecommunications
Each office has a telephone and data outlet mounted 18” above the finished floor. Video projectors and motorized screens are placed in each conference room and the training/meeting room. Each floor has multiple Wi-Fi locations set up to ensure a wireless connection throughout the building.
