The Corporate Headquarters, located in the Great Lakes Region of the United States, is meant to serve as both a functional office and retail space for a large corporation as well as a new focal building for a large outdoor retail park. The new Corporate Headquarters seeks to create a place of refuge from the hustle and bustle of the shopping mall, as well as provide a point of entry into the retail park from the South. In addition to retail, the park is home to many apartments, parking garages, a movie theater, and grocery store. The hope is that by adding an office building, the area will feel more like a modern community.

The Corporate Headquarters features traditional modern American architecture to ensure continuity between the existing portion of the mall and the new building being added. Additionally, the Corporate Headquarters features an open air courtyard in the center of the building for workers to congregate and eat lunch in, as well as to provide light and air to some interior office spaces. The exterior of the building features a rose garden, both to help create a feeling of a grand public space, as well as to give a small nod to the logo of Corporation X.

   The building features many street windows and a large curtain wall feature in order to help integrate the surrounding area into the building. It is believed that since Corporation X was started in the Great Lakes region, they wanted to provide a level of transparency into the space as a way to involve the community in their work.

Historical Requirements

None applicable for this building.


Building Enclosure

Facade: The facade of the Corporate Headquarters is brick and decorative CMU paired with a curtain wall. This was done to mirror the existing architecture of the retail plaza to the north of the site.

Figure 2: Existing Building in Retail Park

Windows: The windows in the Corporate Headquarters feature folding grilles, an aluminum-framed window-wall glazing system, and glazed aluminum curtain walls. More information to follow, awaiting architect response.

Roofing: The primary roof structures is a traditional rigid roof composed of metal deck on w shapes. Above the rigid roof, however, is thermoplastic polyolefin (TPO) Single Ply Roofing. TPO is being utilized in order to comply with ANSI/SPRI Wind Design Standards as well as to conform to the NRCA Roofing and Waterproofing Manual.

Sustainability Features

The primary sustainability feature of this building is its Intensive Green Roof Courtyard in the center of the building. The rectangular courtyard is designed to function as a mini park for the building occupants, and features large planted trees as well as grass and other plants.

Primary Engineering Systems


The structural system of the Corporate Headquarters is primarily a composite steel framing system. The floor system is comprised of composite W-shapes which support a composite concrete and metal deck floor system that utilized lightweight concrete topping. Typical beam sizes are W24x55 while typical girders are W24x68. The average column size is W14x90 and the average bay size is 38'x40'.

The foundation system of the building is composed of grade beams, spread footings, wall footings, and column piers. Due to the poor condition of the soil on site, aggregate piers were pushed into the earth for the column spread footings and piers to sit upon. These aggregate piers greatly increased the soil bearing capacity.

The building's lateral systems is comprised of 8 braced frames made of HSS shapes. These braced frames may be found near the core of the building rise the full height of the building.


The primary electrical service feeding power to the Corporate Headquarters is a 480Y/277V switchboard. The building features distribution boards and panel boards. Additionally, there is an oil generator that works to supply emergency power to the building. There is also an intergrated power center housed on the first floor of the building. In order to be more energy efficient, photoelectric swtiches are used throughout the building as well as outside.


The luminaires in the Corporate Headquarters are 277V. Many of the lamps used throughout the building are flourescents, with T-8 and T-5 rapid-start lamps used in the majority of spaces. Compact Flourescent 4-Pin lamps are also utilized. In addition to flourescents, HID pulse-start and ceramic lamps are used. The building's exterior features many different types of lights, including HID's, compact flourescents, and Luminaire-Mounted Photoelectric Rays.


The Corporate Headquarters' primary heating and cooling system is a Variable Air Volume system. It features 14 rooftop Air Handling Units that provide up to 37,500 CFM and 11 types of terminal boxes, the largest of which has a max airflow of 3000 CFM. In other areas of the building, CRAC and Split Systems are utilized. Radiant Heating is also used in interior office locations. 19 different fan types are used to cool the building, including 2000 CFM in-line centrifugal exhaust fans in the telecommunication rooms and 840 CFM ceiling exhaust fans in the typical electrical rooms.


The project delivery method is design-bid-build. The general contractor of the project is Mark G. Anderson Consultants, Inc. The project broke ground in August 2014 and substantial completion is expected in Spring 2016, with a projected move-in date of Summer 2016 for the building occupants. Due to confidentiality reasons, the owner has requested the the project cost be withheld.


Engineering Support Systems

Fire Protection:

The Corporate Headquarters fire protection is a combination standpipe/wet pipe sprinkler system. The standard pressure used in the sprinkler system is a minimum of 175 psi. The fire sprinkler systems complies with the 2011 Local (State) Fire Code as well as the 2011 State Building Code, NFPA 13, Sprinkler Systems-2010 Edition, and the FM Global Recommended Practices. The building's standpipes are Class 1 and have a minimum flow rate of 500 gmp for the most hydraulically remote standpipe as well as a 250 gmp minmum for each additional standpipe. The minimum design pressure for the standpipes is 100 psi at the top valve outlet. In addition to the standpipe and wet sprinker system the building houses a digital, addressable fire alarm system.


Occupants of the Corporate Headquarters move from floor to floor using the building's stairwells and elevator systems. Four seperate stairwells, one in each quadrant of the building, rise from the ground floor up to the 5th floor, with smaller stairwells reaching from the 5th floor up to the roof. The building also houses four elevators, two near the lobby on the west side of the building, and two near the south east stair tower. Due to the large size of the building and the large number of occupants expected, all four of these elevators rise the entire height of the building.


Each floor of the Corporate Headquarters has it's own telecommunications room in order to better service the needs of Corporate X. Every office space has it's own telephone and data outlet box, and some larger spaces, particularly on the 1st and 2nd floor, have multiple boxes.
