Project  delivery method:   Design-Build

Architecture

design and functional components:
The Monongalia General Hospital addition resides south of the existing hospital building and east of the health care center. The addition, named the Hazel Rudy McQuain Tower, rises five floors, one floor shorter than the existing six floor hospital and will have an elevator reaching the sixth floor of the existing building. The tower connects directly to the existing hospital both in the red brick appearance and matching floor levels. The new building also ties into the existing health care center as well as the service tunnel which runs from the existing hospital building to the health care center. In addition, a new central plant building was incorporated to house all the utilities for the new patient tower.

The tower adds 88 new patient rooms for a combined total of 189 beds. The fourth and fifth floors will each have 36 beds divided into sections of nine beds. Each section will include a separate nursing station. All rooms in the existing building will be renovated to become private rooms with handicap accessible restrooms. The new tower will also house the hospital’s many departments from administration to radiology.

Building envelope:
The main structural system of the tower building consists of cast in place reinforced concrete. A few areas incorperate the use of W-flange steel columns and beams in the central plant and main entrance. The building envelope is a red brick veneer with metal stud back-up to match the red brick exterior on the existing building. The interior partition walls are metal stud framing with gypsum wallboard. The new tower's roof consists of a cast in place concrete structure with a combination of an EPDM ballasted roof system and fully adhered roof system, while the central plant and main entrance use a combination of roof joists and W-flange steel beams.

Building Statistics Part II

Primary Engineering Systems

Construction

Demolition:
The site in which the new tower building is located was previously a parking lot for the hospital. The asphalt parking lot was demolished and removed before further excavation continued. Slight demolition to the existing building and tunnel was needed before tying into the structures.

Support of Excavation:
The new Hazel Ruby McQuain Tower sits directly adjacent to the existing hospital building. With the new tower’s foundations being so close to the foundations of the existing building, the excavation process required a soil nailing support system. The systems consisted of three, 5’ lifts made of 4” thick shotcrete with 2 layers of wire-mesh reinforcing. Each 5’ section uses #10 size bars tensioned to 150 kips. The excavation and soil nailing process required 6-7 days in between lifts in order to insure proper curing time for the shotcrete retaining wall. Most of the soil nailing walls were only temporarily installed and removed upon completion of the new tower’s foundation. In some locations the soil nailing remained permanent, in which the bars were epoxy coated for corrosion protection. In these areas, gravel was placed in between the retention wall and foundation wall to enable water drainage.

Project Delivery:
The delivery method for this project is unique in that it is defined as a design-build delivery method but essentially utilized a competitive bidding process to select the construction manager, instead of the usual design-build or joint venture firms. The project began as the owner brought an architect (FreemanWhite) on board early in the design phase to then plan and design the project. The architect holds a Guaranteed Max Price (GMP) contract with the owner. The at-risk construction manager (Turner) for the project also holds a GMP contract but with the architect and not with the owner (Monongalia General Hospital), as in most cases. This is also where the combination of delivery methods comes in to play. The selection for the CM on the project was declared using 70% document completion, justifying a design-build delivery. The construction team was permitted to break ground under contract of the 70% complete documents. As mentioned, the selection of the CM was done through a competitive bidding process often used in design-bid-build delivery methods, making the delivery method on this project a unique combination of delivery methods.

The architect performed most of the design elements such as architecture, MEP, interiors, and fire and sprinklers. The structural and civil design work, were contracted out by the architect, to third parties engineering companies. The two firms are illustrated on Figure G.1 with their contracts most likely being lump sums.

The CM holds all the contracts with the performing construction companies. The five major subcontractors are shown in Figure G.1. All of the subcontractors hold lump sum contracts with the CM. The requirement for subcontractor selection was a minimum of three bidders per scope package. Each of the subcontractors was required to provide their own performance bond and insurance. Additionally the CM held its own general liability insurance.

Electrical & Lighting

In addition to housing the mechanical equipment, the new central plant also holds most of the electrical equipment with three rooms designated specifically for normal power, emergency power, and generators. The normal operating electrical system uses a 480V, 5000A switchboard unit. Backup power is supplied by two 1500 kW generators through a 480V, 8000A paralleling switchgear. The generators are connected to their own battery pack for instant generator start up. Each battery pack has its own battery charger located in the generator room, to insure proper charging at all times.

The majority of the lighting in the hospital is fluorescent bulbs housed in 2x4 or 2x2 recessed fixtures to match the 2x4 acoustical ceiling tile grid.

Mechanical

In order to handle the large HVAC loads required in a 210,000 sq. ft. hospital building, a new central plant was built to house most of the mechanical equipment for the new tower. The large HVAC loads require the use of seven variable air volume roof-top units, each sized specifically to the type and sizes of the areas they serve. Located on the roof of the central plant are two 500 ton, 1,500 GPM (gallons per minute) cooling towers, with reserved space for the possible addition future chillers. Inside the plant are two 500 ton, 1,500 GPM water-cooled chillers and one 5,175 lb/hr, 100 psi steam boiler. For winter heating the building uses a number of different heating units depending on space use, most of which are supplied by hot water from the new boiler. The main heating system for the new tower is a combination of constant air volume and variable air volume terminal reheat units. The constant volume units control the hot water supply to the heating coil in order to control temperature. The variable air volume units control the air supplied to the space via dampers, as well as the hot water control valve, for more control over the space’s air conditions. A dozen hot water baseboard heaters are also used in a few small public spaces. Electric duct heaters were used in the renovated areas of the existing building.

Structural

Cast in Place Concrete:
The Hazel Ruby McQuain Tower’s structure is primarily cast-in-place concrete. The tower rests on shallow spread footings which support typical sized 24”x24” cast-in-place reinforced concrete columns. The first floor of the tower is partially underground and therefore requires a 14” cast-in-place exterior wall with #4 and #6 size rebars for horizontal and vertical reinforcing. The first floor system is a 5” thick slab-on-grade with 6x6 W.W.F. reinforcing. Floors two through six consist of an 8” thick concrete flat slab system with two-way reinforcing at the top and bottom of the slab, and drop panels at the interior columns. The common beam size is 24”x18” (width x depth), which are located on the exterior of the slabs, large penetrations, and areas of higher loads. The roof structure is the same as the floor systems which support the large air handling units. The stair and elevator walls are 12” thick cast-in-place reinforced concrete and act as the structure’s shear walls. In addition to the new hospital tower, the new central plant also uses cast-in-place concrete spread footings.

Structural Steel:
Although the primary structure is concrete, steel members were used in two areas. The new central lobby uses W12x40 columns and a combination of 12”-18” deep wide flange steel beams. The ski-lighted roof system covering the drive up entrance area also uses a combination of W-flange beams and square tube columns. The new central plant incorporates three W10x33 columns to support the added weight of the two cooling towers on the plant’s roof. The plant uses a combination of W-flange beams and k-series roof joist for the roofing system. Additional steel beams are used on top of the central plant roof as framing support for the heavy cooling towers.

Additional Engineering Systems

Fire Protection

The building uses a combination of wet and dry pipe sprinkler system for fire suppression. The HVAC system has a multitude of safety devises such as fire and smoke detectors and dampers. An intense amount of smoke detectors are used throughout the hospital to ensure quick detection of a fire.

Transportation

The new tower has two sets of elevators for a total of 5 elevators. The public elevators, consisting of three elevators, are located in the north-east corner of the new building, right off the main entrance lobby. These run from the first floor to the existing tower’s sixth floor, also providing access to the new tower’s roof. The staff elevators, consisting of two elevators, are centrally located in the new building, with a third shaft in place for future elevator use. These run from the first floor to the roof in order to access the elevator penthouse and roof-top air handling units.

Telecommunications

Being as the building is a hospital, the communication system is quite extensive. The hospital uses a mix of nurse call systems, intercoms, cameras, telephones, data, and computer systems to operate and manage the operations of the hospital. The large use of equipment throughout the hospital also requires a large amount of receptacles, some of which involve non-typical outlets and power supply for specialized hospital equipment.
