Project Architecture:
The Clark Institute would be consisting of one open first floor and a Basement. The First floor of the Clark would be a large open area glass walls all over to allow light to enter the building except the south side which would be a concrete cast-in-place reinforced wall which would also extend to be the southern wall of the tunnel connecting the museum to the Manton. The stairs in the center of the first floor’s open area leads to the basement which encloses a kitchen with a walk-in freezer, art transit room, paint storage room, a loading dock and a wood shop in the main southern area of the basement. The north extension of the building will hold the utilities such as the electrical room, generator room, and mechanical rooms.

Building Enclosure:
The building enclosure differs on each floor. Concrete cast-in-place columns in a grid like format and load bearing masonry wall to hold the first floor. The basement floor would be a Cast-in-place S.O.G. on footings. The first floor in contrast would also have a cast-in-place S.O.G. with glass enclosure all around the structure except for the southern side which would be a masonry wall. Some of the interior walls are non-load bearing masonry walls.

Sustainability Features:
The Sterling and Francine Clark Art Institute is committed to build a sustainable building to line up with the surrounding environment. It is built with recycled, regional, and even some renewable materials. Also, low emitting materials was kept in mind while building this institute. What’s more, The Clark made the construction waste management a priority in their plans.
There are many efforts made to make the building as much sustainable as possible. For example, the materials were used in this building. For instance, marble claddings, at least 20% of the materials are post-consumer recycled content, regional materials, rapidly renewable materials such as bamboo, wool, cotton insulation, cork, etc. Regarding the low emitting materials, the adhesives, sealants and sealant primers that were used are in comply with the South Coast Air Quality Management District (SCAQMD) Rule #1168. Also, the aerosol adhesives comply with the Green Seal Standard for Commercial Adhesives GS-36.

Demolition
The construction process is split into phases where each represents a specific area of the new extension. Scheduling is discussed in the report to provide the necessary ideas how the job is being done from the early designing phases to substantial completion on the proposed date of July 17, 2013. Demolition work took place in the early stages of construction to provide a room for the new addition. It included the existing plant and parts of the existing plant.

Structural System, Cast in Place Concrete
The foundation would be a 2 way reinforced cast in place flat slab with continuous mat slab which is top and bottom reinforcement. In addition, 18” x 18” concrete columns are all over the cast in place slab on grade (SOG) foundation which is holding the first floor. The first floor itself is also a 2 way reinforced slob on grade with concrete columns placed uniformly across the first floor. Concrete columns heights range from 57 feet to 12 feet depending on the location although most columns have a height of 17 feet. The SOG has thickness ranging from 2.5”, which would be placed on a galvanized composite metal deck, up to 16” which is a two way slab. Strength of concrete SOG in this building should be 5000psi with the exception of the 2.5” SOG which would be 3000 psi. Concrete will mostly be pumped using a pump truck although some areas may require a standard crane and bucket method.

Mechanical System
The Mechanical system is located in the basement in the north side of the. The HVAC system will be using a fuel supply pump to operate the boiler and the generator. There are two main hot water boilers that supply heat to the Sterling and Francine Clark Art Institute each running at 150 HP to supply a NET MBH of 5021 per boiler. In addition, there will be 6 heat exchanger units, 3 located in the chiller room and the other 3 will be in the boiler room. As for the chilled water system, there will be 3 chillers; The 2 main chillers will have a capacity of 290 tons with a GPM of 696 supplying the Museum and the Manton (the existing building next to the new addition). The generator will be placed in the generator room in the plant part of the new addition on a concrete pad with a thickness of 24”. There are a total of 8 sound attenuators for the mechanical equipment located in the Mechanical room.

Electrical System
The electrical room is also located in the basement in the north side along with the mechanical room. There are a large range of lighting fixtures that will be used throughout the museum. The voltages are 120 V for CFL and T4’s while the voltage would be 277V for T8, MH, LED lighting and Par 38. The Sterling and Francine Clark Art Institute will be running on a 15KV feeder that branches of the main utility line. A dry type 2000kVA transformer will transform the electricity to produce a 3 phase (4 wire) 480/277V circuit. There is an emergency generator that can generate 1500KW/1875KVA
