Architecture:

The roofing system is the most prominent component to the exterior architecture.  The sloped roof membrane is accented with an aluminum façade trim along the perimeter of the building.  However, the roof slopes from either side do not always line up to make a perfect “V,” but rather either the East or the West end will rise up several feet over the other.  The complicated roofing system brings accent to the irregular shape of the building.

The entrance to the building is marked by a column of windows that runs three stories.  Aside from this column of windows the building has a small proportion of windows to walls.  The exterior façade is composed of three different styles of monarch or double monarch bricks and corrugated metal.  The bulk of the façade is a tan monarch brick which dominates the architecture accept for a large portion of the first floor where other types of monarch or double monarch bricks are used, and large sections of corrugated metal panel adjacent to the roof.

Spatially, the building is divided into two sections.  The northern section holds general offices and more utility type rooms, such as mechanical equipment, the cafeteria and the gymnasium.  The southern end is dominated by classrooms.  To help with a smooth gradient between classroom and utility, more utility type classrooms such as music rooms and in-school suspension bridge the gap between the southern and northern ends of the building.  This segregation aids in sound isolation between quite and loud rooms along with providing a logical layout of the building to occupants that may be unfamiliar with the building.

Zoning:

Non-separated mixed occupancy use group E with A-4, A-3, A-2, and B as accessory spaces

     

Building envelope:

Brick veneer with cement masonry block back up walls.  EPDM membrane roof system with rigid insulation and metal roof deck.

     

Structural Systems:

The lower level of the building is a 5 inch concrete slab on grade with mesh and polypropylene fibers.  Elevated flooring systems consist of concrete slabs on metal decking.  Typical columns are TS8x8x1/4.  Outside walls are composed of a brick veneer with cement masonry block back up.  The roofing system consists of an EPDM membrane with ridged insulation and a metal roof deck.

     

Construction:

Construction for the school began on April 24, 2006 and is still in progress.  The project delivery method was design-bid-build.  The Bid Close date was March 23, 2006 and construction is expected to be completed in the summer of 2007.

   

Electrical:

The total electric demand for the building is 1167 kVA including a 15% spare capacity.  The lighting for the building requires 102 kVA and the HVAC system consumes 550 kVA.  The main 2000A electrical switch board is three pull and four wire.  Primary service to the building is 480Y/277V while the secondary service is 208Y/120V.  There is a single 60 kW natural gas driven generator for emergency situations.

   

Lighting:

The lighting system for the offices and the school portions of the building are grid mounted 2 ft by 4 ft fluorescent troffers.  The gymnasium is lit with 22 in diameter low bay fluorescent fixtures.

   

Mechanical:

The mechanical system is dominated by three variable air volume air handling units with supply flows of 22000, 18000, and 12000 cfm and plenum return.  Each air handling unit is fully equipped with a total energy wheel with a variable frequency drive.  There are 78 single duct or series fan powered terminal devices with local hot water reheat in the building.  There are two radiant panels in the building with capacities of 853 and 1280 MBH.  The hot water heating system is served by two 1500 MBH natural gas boilers.

   

Fire Protection:

The building has complete fire protection.   Classrooms contain recessed sprinkler heads, offices contain concealed sprinkler heads and the Gymnasium contains upright sprinkler heads with a protective wire cage.
