[Architecture]

The new Celgene Building L will be a two story pharmaceutical office building built atop four stories of underground parking.  There will be approximately 200,000 SF of office space and 325,000 SF of underground parking with 950 parking spaces.  The project is aiming to achieve LEED Gold.  The owner and architect strived to design a building that will help Celgene continue to accelerate their work in discovering and developing new innovative therapies.
 

[Codes]

Major National Model Codes in addition to all City, State, and Local Codes:

• 1996 BOCA National Building Code

• 2009 International Building Code (IBC) – New Jersey Edition

• 2009 International Mechanical Code

• 2009 National Standard Plumbing Code

• 2009 International Fire Code

• 2011 National Electrical Code

 

[Zoning]

The Celgene campus is located within the PROD-2 (Planned Research Office Development) zone of Summit, NJ.  As stated by Article 4 of the Summit, NJ Development Regulations, this zone is intended to accommodate office, scientific, and applied research facilities devoted to research, design, and testing.  The nature, scale, and function of these buildings shall be regulated as to not pose any significant or unusual risk to public health or safety.    
 

Furthermore, according to the Schedule of Space Regulations, some restrictions for the PROD-2 district are as follows:​

• Maximum of 3 stories and 48 foot building height

• Maximum floor area ratio of 50%

• A building set back of 125 feet from an abutting residential zone boundary line 

• Must be equipped with positive screening when adjacent to a residential zone

 

[Historical Requirements]

There are no historical requirements that apply to this project.

 

[Façade]

The façade of the building consists of brick veneer, metal panel, and an anodized aluminum curtain wall system with 1” tempered insulating glass.  The North, South, and East elevations incorporate alternating sections of full height curtain wall and brick enveloped curtain wall, as seen in Figure 1.  Also seen on these elevations are portions of the second and third floor parking garage, which is a precast concrete system.  The West façade continues this alternating pattern but introduces metal panel at the main entrance and the connecting bridge to an existing building, as seen in Figure 2.

[Roofing]

The roofing on this building is a TPO (Thermoplastic Polyolefin) Roofing System.  The roofing system consists of:

• 1-1/2” metal deck

• 1/2" densdeck board on top of metal deck

• 6” polyisocyanurate roofing insulation

• 5/8” densdeck board on top of insulation

• 80 mil white TPO membrane  

This TPO Roofing System is heat-reflective and energy efficient.  The top membrane provides excellence resistance to ultraviolet, ozone, and chemical exposure.  It will also remain watertight throughout exposure to weather and improve the lifecycle of the roof itself.

[Sustainability Features]
 

This project is aiming to achieve a LEED Gold certification under LEED 2009 for New Construction and Major Renovations. Some methods that are being utilized to achieve this goal include a Construction IAQ Management Plan, a Construction Waste Management Plan, and an Erosion and Sedimentation Control Plan.  In addition to those plans, local and recycled materials will be used throughout the project scope.

 

 

----------------------------------------------------Part 2: Engineering Systems-----------------------------------------------------

 

[Construction/Site]

 

The ‘Celgene Building L’ project is being built over an existing parking lot.  Before construction could begin, some demolition needed to occur.  The main demolition that was needed was removing existing water mains and storm water piping.  In addition to that, the existing asphalt, curbing, and guardrails needed to be removed.

 

Due to the site being located over an existing parking lot adjacent to buildings, Turner Construction has limited space to construct the building.  The site is located on the Eastern extents of the campus so pedestrians should not be an issue.  There is some contractor parking located adjacent to the Job Trailers.  Although the site has limited space overall, the subcontractors have a relatively large area to lay down their materials.  In order to gain access to the excavated area for constructing the underground parking garage, a large ramp is situated on the East side of the site and will stay in place until the garage is completed.

 

During excavation, soldier pile lagging was utilized on a portion of the West elevation for stabilization.  Several cranes were used during the project.  A crawler crane with a luffing jib was used for the precast concrete and a truck mounted crane with a luffing jib was used for the steel erection.  A smaller truck mounted hydraulic crane was used for the pre-fab brick erection, metal panel installation, and mechanical unit installation. 

 

[Structural System]

 

The structural system for the underground parking garage is 3 stories of precast concrete set on spread footings with shear walls.  The slab on grade is 5”, 4000 PSI normal weight concrete reinforced with #4 bars at 16” each way.  The gravity system switches to composite steel in the office portion of the building.  The floor construction is 3 1/4”, 3500 PSI light weight concrete reinforced with welded wire fabric on a 3” 20 gauge galvanized composite floor deck.  The lateral system is a moment frame.                  

 

[Mechanical System]

 

The main mechanical system comprises of 4 roof top evaporative condenser VAV packaged units.  All four air handling units will include energy wheels with bypass dampers for air economy cycle use.  The distribution system consists of VAV boxes with hydronic heat and overhead ductwork, ceiling mounted diffusers, and return grilles.  The ceiling space is utilized as the return air plenum.  Separate zones are provided for corner and perimeter offices.  Interior offices are grouped three per box at 2,000 CFM per box.  The VAV boxes are located outside of the offices for enhanced acoustical care.  Radiant heat will also be provided for the first occupied floor.           

 

[Electrical System]

 

The electrical service for the new building will be provided by medium voltage metal clad switchgear located in the adjacent Building ‘X’.  A 5 kV single conductor shielded cable is run to a substation in the penthouse from an existing 1200 amp vacuum circuit breaker.  The Substation consists of a 15 kV load interrupter switch with 400A fuses, a 2500 kVA transformer (5 kV – 480/277V - 3Ø – 4W), and a secondary switchboard rated at 4000A with a main circuit breaker and feeder breakers.  All circuit breakers have long-time, short-time, instantaneous, and ground fault trips.  Feeder breakers in the switchgear feed distribution panels which in turn feed downstream lighting, power, and mechanical equipment.

 

[Enclosure]

 

The façade of the building consists of brick veneer, metal panel, and an anodized aluminum curtain wall system with 1” tempered insulating glass.  The North, South, and East elevations incorporate alternating sections of full height curtain wall and brick enveloped curtain wall.  Also seen on these elevations are portions of the second and third floor parking garage.  The West façade continues this alternating pattern but introduces metal panel at the main entrance and the connecting bridge to the existing main building.
