//architectural commentary

The Monongalia General Hospital can be divided into four quads (A, B, C, and D). The majority of Quads B and C is the existing building with an expansion for a new power plant on the eastern wing of Quad C. Quads A and D are new additions to the hospital with Quad A housing offices and storage on the ground floor followed by examination rooms, lounges, and patient rooms on the five floors above as well as the rooftop allotted for mechanical equipment. Quad D will serve as a connection from the main hospital building to an existing HHC building and will house mechanical rooms, labs, and a reception area, followed by offices and rooms for various departments such as the radiology and trauma departments above. Quad D will also house the surgery area in the second floor.

The floor plans of each of the quad follow a fairly consistent pattern with some exceptions in Quad D to allow more space for different medical departments and to allocate a whole floor for the surgery rooms. To accommodate for elevation differences between the existing and the new hospital building, slopes have been placed accordingly to connect the traffic between the buildings. Partitions for rooms are typically gypsum board on metal studs, with the exception of rooms such as the radiology lab which requires radioactivity retardant material.

Primarily, the exterior of the building is a brick façade tied to structural concrete walls with openings for punch windows and curtain wall systems. One would find that the different sections of the Hospital have different heights. Windows are typically aluminum punch window units and located where there are offices and patient rooms, usually located on the higher elevations of the Hospital. Aluminum curtain wall systems can be seen all around the Hospital, oriented around lobbies and other major openings on plan. The system consists of insulated tempered spandrel glass framed by aluminum mullions which is tied into the concrete structural system.

The roof system consists of two different systems, the adhered roof system and the ballasted roof system. The roof is laid out in a flat plan providing room for mechanical equipment and a skylight for the entrance lobby located in Quad A. The ballasted roof system spans from Quad A to D and houses most of the mechanical equipment for the building. The rest of the roof of this Hospital adhered roof system.

//structural commentary

The Monongalia General Hospital’s main structural system is a combination of concrete shear walls and moment frame with a total of one hundred 24” x 24” columns with varying heights supporting the building. Shear walls are located around openings on plan such as elevator shafts and stair ways to provide resistance against lateral loads. The floor system in the Hospital is a flat slab supported by columns and exterior beams.

The columns provide some resistance against lateral loads and rests atop concrete spread footings placed no more than ten feet below grade. 5 inch slab on grades are also provided as a foundation system on the ground floor. Keeping in mind that the Hospital has varying elevations, the columns all vary in height, providing support from the ground to the roof of the building. These columns are usually 27 feet apart and follow a square grid pattern. From the second floor up to the roof, the floor system is primarily an eight inch flat slab system supported by the aforementioned columns and by edge beams usually 24” x 18” in size. Interior beams are almost nonexistent in the structural system except by areas where there are openings for stairwells and elevator shafts and other select locations. Composite floor systems utilizing W12 shapes, although very minimal; can be found in Quads A and C providing support for heavier loads such as a power generator and as a canopy above the lobby entrance.

Shear walls are located in three major locations in the building (see Figure 3, in Tech 1) and are responsible for resisting lateral loads. These walls, much like the columns vary in height depending on their location in the Hospital due to its varying elevations. The shear walls are located where there are openings on plan and used as elevator shafts and stairwells.

//lighting and electrical commentary

The hospital is powered by two systems: a 480/277V 3 phase, 4 wire system and a 208/120V 3 phase, 4 wire system. All of the mechanical systems are linked to the 480/277V as well as the medical equipment used throughout the Hospital. Lighting fixtures are served by the latter, and utilizes electronic type ballasts all with a 95% power factor. Time switches are provided for all exterior lighting in the Hospital grounds. Two 1500KW diesel engine generators housed in Quad C and will provide emergency power in times of need.

//mechanical commentary

Seven rooftop VAV-AHU’s with capacities ranging from 11,500 to 37,000 cubic feet per minute work as the mechanical system of the Hospital. Water-cooled chiller, cooling tower, and steam boiler are also located on the rooftop. Hot and cold water are provided to all toilets, operation and examination rooms, and the kitchen. Heating is provided in all rooms and hallways via an electrical duct heater. Due to its importance in the hospital, the mechanical systems are connected to the emergency power generator located in Quad C.

//construction method

The Monongalia General Hospital was built under a design-build contract with a GMP set at $68,000,000 by the Turner Construction Company. The ground was broken with 70% of the documents and the sub-contracts are based on these documents in lieu of 100%.

//fire safety

The fire safety systems include fire rated partitions and doors as well as various types of sprinklers abiding by the West Virginia Fire Code as well as the NFPA 13. As such, the sprinkler systems include both wet and dry systems with various sprinkler head types such as concealed, recessed pendent, and upright. The Hospital provides nine smoke compartments per floor ranging in size from 1,450 square feet to 21,320 square feet on the first and second floors, three to six smoke compartments per floor on the floors above ranging in size from 2,620 square feet to 19,870 square feet.

//transportation system

The Hospital is a barrier free environment as per ADA codes. Vertical transportation is provided by twelve elevators placed in various locations on plan. Elevators provide access for patients, visitors, doctors, and services. Stairs are also located near the elevators to provide emergency access to the ground floor and out.

//telecommunication system

Telephone service will be provided to the Hospital and all of its rooms by empty conduit, raceway, and/or trough from incoming service area to outlet boxes. Conduits will be run from the mainframe room to the telecommunications closets.
