WELCOME TO BRIAN NAHAS' AE SENIOR THESIS E-PORTFOLIO
 
  Building Statistics | Part II  
Primary Engineering Systems

The building will have electrical and tele-data components such as backup generators, critical circuitry to help ensure minimal power interruption, nurse call systems for effective communication and code blue systems throughout the campus. The supply power enters the site from the south-west corner, and follows the maintenance road up to the loading dock area of the medical center. This area hosts the backup generators and all utility connection for the facility. This facility has two emergency generators, with the capabilities for a third. These generators are 100KW, 1250KVA each and tie directly into the main power system.

 

The power enters the electrical control room through a 5000A Bus Duct that comes off of a 3750 KVA, 480/277V transformer. The medical center features a redundant supply system in parallel, permitting uninterrupted power supply. Once entering the electrical control room, the 500A, 480/277, 3 phase, 4 wire feed the building systems. The building system is also wired with for critical power, emergency power, and emergency power life safety services directly from the backup generators.

 

The medical center is serviced by seventy-nine 480/277V and ninety-six 120/208V panel boards which distribute power throughout the building to meet the services need of hospital equipment, staff, and patients.

The building's mechanical systems are made up of several main components including boilers, custom air handlers, cooling towers, chillers and variable air volume boxes. The central utility plant (CUP) houses all of the major mechanical equipment that is not installed rooftop. The CUP is located at in the north-west corner of the facility and was designed at a lower elevation to permit proper pipe and utility clearances above the equipment. There are four major vertical shafts (150 - 200SF each) that service the East and West wings of the patient tower. In the central core, there are two vertical shafts for MEP distribution for the Atrium and high roof services.

 

The New Regional Medical Center's HVAC system is serviced by seven custom outdoor air handling units and two indoor air handling units. The outdoor AHU's are located as rooftop units, and the two indoor units are located in the CUP. They operate as a VAV mixed air system. There are three water chillers (825Ton, 825Ton, 450Ton) which service these AHU's cooling conditions, while the building's heating system is serviced by two 500 HP boilers and one 400 HP boiler which also located in the CUP. Ductwork is utilized to transport the air to each space, and all patient rooms contain VAV boxes for individual controls. Hydronic piping transports the chilled and hot water to each AHU. The Operating Rooms have a dedicated AHU system which features a blow-through arrangement and requires a minimum of 50,300 CFM of outside air in comparison to its 45,000 CFM supply air.

 
Structural System
The New Regional Medical Center features a structural steel frame which is arranged on a grid pattern of 30 feet by 30 feet. The column system includes splices that are placed four feet about first floor, and four feet above the third floor. This permits ease of connection and assembly. The columns are comprised of W12 and W14 which range from 49 lbs/lf to 170 lbs/lf. The maximum load for the interior columns of the building are estimated to be 800 kips, and the maximum load for the exterior columns of the building are estimated to be 605 kips. This project features eight different braced frame configurations which are oriented perpendicular to the south facade in the East and West Towers. The framing plan is generally comprised of W24 girders with W14 beams. All girders have flexible moment connections designed for lateral loads on the structure (see Detail 1).
 

The slab configurations various throughout the structure, and utilize different assembly configurations. All slabs are comprised of composite metal decking, shear studs, and welded-wire-fabric.

 

A 300 ton 2250 Manitowoc crane will be placing all structural steel. This crawler crane travels around the perimeter of the building per the sequencing narration and the site logistics plans. The complete crane arrived on site via 15 trucks, and is schedule to perform all major lifts for the duration of the project. The 2250 model features a 500 HP engine and a 300ft boom, with the option to extend to 400ft with the luffing jib attached.
