ARCHITECTURE (DESIGN AND FUNCTIONAL COMPONENTS)
NICoE will be a 72,000 square foot, two-story facility located on the Navy campus at Bethesda, Maryland, adjacent to the new Walter Reed National Military Medical Center. It will have access to the Uniformed Services University, the National Institutes of Health, and the Veterans Health Administration. NICoE will be designed to provide the most advanced services for advanced diagnostics, initial treatment plan and family education. It will also introduce therapeutic modalities, referral and reintegration support for military personnel and veterans with TBI, post traumatic stress disorder, and/or complex psychological health issues.
The architectural features are highlighted on the northwest side of the building. It is composed of an exterior curved curtain wall system along with concrete precast panels extending the height of the building 38’-8”. This houses the healing and public areas of the building such as: auditorium, waiting rooms, lounge, the media “Dive” room, the CAREN (Computer Assisted Rehabilitation Environment) and the spacious lobbies. Situated within the building on the East and south side are clinical spaces which include: MRI rooms, PET/CT rooms, physical, occupational, recreational therapy, Sleep labs, Research Tech, and other support spaces. There are two different roof levels that towers the building. The low roof extends throughout the east and south side and holds some of the heavy mechanical equipment. The high flat roof ties into the curved curtain wall system on the north east and west side of the building giving it a special architectural feature. Finally, spacious lobbies and playground areas are provided for the friends and families to relax while their loved ones are being treated.
"This facility will provide treatment that is available nowhere else in the world," said Phil Tobey, a senior vice president at SmithGroup. "With its comprehensive programs and advanced technology, we believe this facility will accelerate the U.S. leadership in the treatment of traumatic brain injuries, and provide the best possible care for the men and women of our armed services."

HISTORICAL REQUIREMENTS OF BUILDING OR ZONE WHERE BUILT
The NICoE’s site is a historic zone controlled by the National Capital Planning Commission.
BUILDING ENCLOSURE
The northwest side of the building is composed of: a 10" deep curtain wall system and 7" deep precast concrete panels that alternate at various width intervals. These alternating systems extend the entire height of the building (38'-8"). Along the northeast to south side of the building are 10" thick precast concrete panels with a punched-in two story window wall system. This part of the building’s height is 32’-8”. The type of glass used on the window wall system matches the curtain wall glass on the north side of the building. The Southwest edge of the building envelop is composed of: 10” thick precast concrete panels, 1 story height windows, and 12’-6” mechanical louvers. Finally, on the north side of the building is the grand entrance along with the drop off area. In addition, alternate entrances are located on all four sides.
There are two different roof levels to the National Intrepid Center of Excellence facility. Both the low and high roof consists of: Modified bituminous vapor retarder sheets (self-adhering sheets of rubberized asphalt laminated to a polyethylene film) are applied directly on the concrete slab, and thermoplastic polyolefin (TPO) membrane system. The TPO is internally fabric or scrim reinforces, uniform and flexible. It includes an initial solar reflectance of at least 0.76 in addition to an emissivity of at least 0.9. The membrane is also in compliance with the U.S EPA energy star reflective roof product and is a U.S EPA energy star certified. Along with the TPO membrane, the insulation used is a Type II Polyisocyanurate board, with a 4” minimum thickness with felt or glass-fiber mat faced on both major surfaces. The boards are fabricated to a slope of ¼” per 12” with a concrete slab.
SUSTAINABILITY FEATURES
The NICoE is a LEED certified building which incorporates many sustainability design features. One of the most visible features is the curtain wall system which is located on the north and west side of the building. There are two different types of glass used within the curtain wall system. Both the IGU-1 and the IGU-3 is a 1.153inch thick glass which is a tinted heat strength float glass. It has a low emissivity coating laminated with clear float glass (LGU-1) with a visible light transmission value of 54%. The IGU-1 has a UV transmittance value of <1% and IGU-3 has a winter U-value of 0.28 and a summer U-value of 0.26. This will help maintain the space at a comfortable temperature environment and at the same time minimize the energy used to cool and heat the building.
Site development, water use reduction, construction waste management, enhance commissioning and using both regional and low-emitting material has given the NICoE a drive to comprise a cold certified LEED building
CONSTRUCTION
A demolition plan had to be put in place for the preexisting building (dormitory for noncommissioned officers (NCO)) before any new construction had begun. Soil testing was done after the demolition, to examine if the strength of the existing soil meets the requirements for the new NICoE building. Looking over the soil borings it was suggested to re-compact the soil to meet the required structural strength of 3000psf. Although, during excavation some unexpected asbestos was found, it did not affect the schedule of the project and was handled accordingly.
The building broke ground on March 6th, 2009 and is scheduled to be completed within a 16 month period. Turner Construction is the construction management group on site along with Smithgroup, which is the design firm for the NICoE. No bids were collected for this job. Mr. Ronald fisher had asked the CEO of Turner Construction to build this project as a contribution to the soldiers of this country. This project will be delivery as a design – assist job between Turner Construction and Smithgroup. The mechanical and plumbing part will be done by Turner in a design – build method. The initial budget is approximately $65 million under a GMP contract.
The construction process will start from the northeast side and end at the northwest side of building. The FRP of the footings and foundation walls rapidly followed the cutting of the soil to grade. The under slab mechanical, electrical and telecom came in next. Seven pour sections were used to lay the slab on grade. The management of the Turner construction team has been successful in attaining the planned schedule of this project so far and continues to do so.
The site logistics plan that has been put in place by the construction management on the site has been in favor of the construction methods that take place on a daily basis. The tower crane location along with the position of the material staging has made the lifts and placements of the materials a very manageable task. Palmer road acts as the main access to the site for all of material deliveries. Along with that comes a temporary gravel road which was constructed around the building’s footprint for ease of access.
This project is expected to acquire LEED certification, which will meet the standards of the USBGC. This arises some challenges in the construction phase since many trades are just beginning to understand the requirements of LEED certifications. Along with that, building information modeling (BIM) is used in the design and construction phases of the NICoE project. By having the coordination and communication between different trades more sufficient and successful, the schedule and cost of the overall project will be reduced.
ELECTRICAL
NICoE’s electrical system begins at the central utility plant on base and is transferred to the electrical room which is located on southwest side of the building. The power is received using a 2500 KVA transformer which steps down the voltage from a 13.8KV to a nominal system voltage of a 480Y/277V, 3PH, 4-Wire, which services most of the loads in the building. Receptacles and some lighting fixtures receive power through a 208Y/120V, 3P, 4W transformer. A 3000A switchboard provides power to all loads in the building.
As for emergency power in the building, an exterior factory –assembled and tested standby diesel generator rated at 400KW, 480Y/277V, 3p,4W system with sub-base fuel tank is provided. Along with the generator are two different circuit breakers rated at 600A, 3p and 225A, 30P. Also, a 225 KVA UPS battery backup system is connected to two PDUs that serve the emergency power in the service room located on the second floor.
LIGHTING
The NICoE’s interior lighting consists of 80 different types of fixtures. In the southeast and south side of the building, lighting fixtures are mostly 408Y/277V downlight fluorescents along with occupancy sensors. Special lighting fixtures with glare shields are used in the medical operational rooms for a smooth and calming environment. The two floor level open lobby consists of: 408Y/277V recessed metal halide mounted fixtures with photosensor-dimmable lighting control system, downlight fluorescents, and linear recessed fluorescent fixture. In the art and music room, 208Y/120V metal halide track fixtures are used. The lighting of the building is served via 480Y/277V, 3 phase, 4 wire panels. As for the exterior lighting of the building, a 277V metal halide pole lights, which are 18’ above grade, and bollards lights with diffusion lenses combine to beautify the playground, sidewalks and vehicular pathways.
MECHANICAL
The chilled water supply and return lines along with the high pressure steam and the electircal pump condensate lines are run underground from the central utility plant on base to the building mechanical room. The high pressure steam system is used for the domestic hot water and also as a main source for heating the building. Constant volume unitary air conditioning units are used as a source of cooling the building. A field erected air handling unit located on the second floor in the mechanical room is used as a main source to cool the building. The AHU’s supply airflow max is 86,000CFM and min of 68,000 CFM. In addition, variable air volume (VAV) and constant volume control boxes are used throughout the building to maintain the required temperature. Chilled water pumps located on the first floor in the mechanical room will have a capacity of 950 GPM with a motor data of 25HP, 1.750RPMs, 460 volts, and 3PH. Heating hot water pumps located on the second floor mechanical room will have a capacity of 300 GPM with a motor data of 15HP, 1,750RPMs, 460 volts and 3PH. Lastly, an air conditioning unit located in the computer rooms is used for the: server room, MRI equipment, PET/CT room, CAREN equipment, and media “Dive” room.
STRUCTURAL
The structural system for the NICoE is a very simple concrete structure. It starts with the foundation/entry level plan that consist of reinforced concrete spread footing (3000psi) ranging from 4’-6”x 4’-6” x 12” to 15’x 15’x33” (WxLxD). Foundations are a minimum of 2’-6” below grade. First level is a 5” thick cast – in place concrete slab on grade (3500psi) with a 6” - 12” transitions in some spaces. The majority of the column bay is 30’x30’ on the northeast to the southeast core of the building. As for the northwest and the southwest sides the round column bay varies, due to its curved structure, anywhere from 44’x 30’ to 16’x 14’. Four of the round concrete column footings along with 8” round masonry wall will be devoted to support the CAREN system. The concrete column schedule ranges from 24”x 24” , 12”x 24” ,16”x30” and 16”x24”. The floor to floor height is 15’ with 5’- 6” difference between the low roof and high roof. The second floor, low roof and high roof structural plan is composed of a 9” thick two – way reinforced concrete slab (4000psi) with various location drops ranging from 8” – 15”.The central park area requires a post tension reinforced concrete due its heavy loads. The reinforced concrete columns extend to the second floor and require a change in the compressive strength to a 4000psi with a 10’x10’x8”drop panels. Also at the high roof, low roof and around the curved northwest exterior walls are a 24” diameter circular concrete columns. HSS steel is used at the northwest curved wall and skylight located above the central park for additional structural support. The reinforced concrete beam and girder size ranges from 12”x18” to 48”x 17” (W x H) with a maximum of 36” depth.
FIRE PROTECTION
The NICoE is designed with a wet-Pipe Sprinkler system. The interior of the building is broken into light hazard occupancy (admin areas, assembly areas, computer rooms etc.) and normal hazardous occupancy (storage areas, mechanical and electrical rooms and similar stockpiles of combustion materials do not exceed 8’-0”). This provides for the light hazard areas a 0.10GPM per Sq.Ft and a 0.15GPM for the ordinary hazard areas over the hydraulically most remote 3000sq.ft.The fire command center is located on the ground floor in the engineering equipment room on the southwest edge of the building. This room houses the fire alarm control panel, voice amplifier panel, voice evacuation panel, transient voltage surge suppression, and 2 notification appliance power extended panel etc. The fire department connection is located on the north side of the building. A pre-action sprinkler system is installed in the server room on the second floor. Each floor, including core and shell is equipped with fire alarm strobe-speaker appliance; manual pull stations, ceiling and wall mounted photoelectric smoke detectors, and heat detectors.
