Exterior Walls:

The building uses a curtain wall system with a steel frame. There are several different types of exterior materials used including a storefront system, metallic panels, metal cladding, which covers the columns, and also some stucco is used some areas.

Roofing System:

There are basically three types of roofing systems used in the building. The first is a green roof system which is a built up system using Modified Bitumen plies for deck waterproofing. The second is a thermoplastic membrane roofing with Sanafil PVC single ply material, which occurs on the high roof levels. The third is a Simplast Modified Bitumen roofing system. This occurs on the lower roof levels. These roofing systems are applied over tapered roof insulation.

Building Systems

Mechanical System:

The air mechanical system for the Pediatric Inpatient Addition uses 7 air handling units.  In order to maintain sensitive pressure differences between certain spaces to prevent the spread of hazardous air contaminants, all of the units supply a constant volume of air. The air handlers are housed in the mechanical penthouse above level three and serve each of the four levels through two centrally-located mechanical shafts.  Three air handlers serve the operating room level (ground level), with one of those units supplying 100% outdoor air.  Two air handlers serve the entrance level (level 1) and the remaining two units serve the upper two levels.  The roof mechanical room also houses two 2000 MBH boilers that supply hot water to AH-3 and reheat coils throughout the building.

Each space within the Pediatric Inpatient Addition is served with a hot water reheat coil and the building has 145 of these reheat coils with a 180˚F entering water temperature.  Twenty-one fan coil units serve spaces throughout the building such as electrical rooms, elevator machine rooms, and telecom rooms.  The entering water temperature is 45˚F and is supplied from the chillers located in the central plant.

The central plant is located just adjacent to the Pediatric Inpatient Addition and was included in a separate drawing package.  The central plant houses two 500-ton centrifugal water chillers that cool 1000 gpm from 56˚F to 44˚F.  Two counter flow cooling towers cool 1500 gpm from 95˚F to 85˚F and are located on the roof of the central plant.

Electrical System:

The electrical service for the Pediatric Inpatient Addition is fed from the utility through a  pad-mount transformer located in the service switchgear yard.  The utility transformer serves a 4000A switchboard at 480Y/277V, 3-phase, 4-wire.  The central plant is fed directly from this 4000A board, and the Addition is fed from a 2500A distribution board in the main electrical room located on the first floor.

The emergency system is comprised of two 750KW/938KVA diesel generators, each with 1200A, 3 pole output circuit breakers that tie into a paralleling switchgear arrangement.  Four automatic transfer switches segregate the emergency loads by the critical nature of the loads they serve.  The Life Safety branch serves only those items critical to getting people safely out of the building, including egress lighting, fire alarm, and smoke control systems.  The Critical branch serves all of the patient care items, which includes task lighting and receptacles in areas such as neonatal care units, operating rooms, patient rooms, imaging, and recovery.  Life support machines are also on this branch.  Also the Equipment branch serves all of the HVAC equipment as well some other types of equipment.

Lighting System:

A variety of light fixtures were used in the Pediatric Inpatient Addition.  The back-of-house lighting uses primarily 2’x4’ recessed light fixtures with fluorescent lamps and T-8 ballasts for maximum energy efficiency.  In the operating rooms, special OR-type 2’x4’ 6-lamp light fixtures were used for maximum light output.  Located around the nurse stations and elsewhere throughout the building Color Kinetics was used.  These are LED lamp types that that produce different colored lights using primary colors to accent and create a warm atmosphere.

Structural System:

The structural system for the Pediatric Inpatient Addition is a steel frame construction that utilizes a proprietary system called SidePlate. This system is ideally suited to protect structures against terrorism, seismic events, or other natural disasters. The alternative to Sideplate would be to go with a braced frame which would add to the gross square footage of the building footprint and also create awkward "X" braces on exterior and interior walls that have to be designed around. There are two reasons why this system was implemented. First, it has some pre-approved beam sizing which allows it to go through the state agency quicker for review and approval. Second, the lateral force resisting system is inherent to the design of the Sideplate. The system is similar to a steel moment frame, except that steel moment design has been suspect to lateral force resistance due to cracking of the welds that attach the beams to the columns. The Sideplate system is an improvement over that technology.

All of the beams and columns in the Pediatric Inpatient Addition are from the W-series. The flooring system is made up of vented steel decking with concrete flooring (a higher grade than lightweight concrete) and it is 6-1/4" high from the bottom of the metal flute to the top of the concrete. The foundation that is used is a mat foundation that is 3 feet deep with 2 feet of sand and a methane and waterproofing membrane above that. Then there is a 6" concrete floor slab above the sand layer. The columns run down to the 3 foot mat slab. The foundation walls are poured in place concrete at the perimeter where they are below the surface and act as retaining walls.

Fire Protection:

The Pediatric Inpatient Addition is fully sprinkled with a wet pipe sprinkler system and is monitored by a fire alarm signaling system.  The building is sprinkled according to NFPA occupancy types: Light Hazard, Ordinary Hazard-1, Ordinary Hazard-2, Extra Hazard-1, and Extra Hazard-2.

Low Voltage System:

As the Pediatric Inpatient Addition is a hospital, it has many telecommunications systems.  The building has a fire alarm system and security system.  Also included is a telephone and data system, nurse call, and a public address and paging intercom system.  The patient rooms are outfitted with cable television and installed throughout the building are medical equipment alarms.  Also the building is outfitted with building management and energy management systems.

Transportation System:

The Pediatric Inpatient Addition has four elevators for circulation.  Two elevators are located in the lobby and are public elevators.  There is also a patient elevator located in the surgery center and intensive care units and a service elevator for moving equipment.

Important Note:

The existing Miller Children’s Hospital is considered a non-conforming building by California code.  This means that although the existing Miller Children’s Hospital has enough capacity to serve the addition, the two systems had to be completely separated from one another.  Therefore, the Pediatric Inpatient Addition has its own central plant, utilities, etc.  Essentially, the two buildings are completely disconnected from one another and function separately.

 

Note: While great efforts have been taken to provide accurate and complete information on the pages of CPEP, please be aware that the information contained herewith is considered a work‐in‐progress for this thesis project. Modifications and changes related to the original building designs and construction methodologies for this senior thesis project are solely the interpretation of Stephen Haines. Changes and discrepancies in no way imply that the original design contained errors or was flawed. Differing assumptions, code references, requirements, and methodologies have been incorporated into this thesis project; therefore, investigation results may vary from the original design.
