Civil Design Narrative
Project Overview
The civil portion of the project involves the installation of two approximately 23.5-ft by 56-ft trailers and the construction of a parking lot to serve the new temporary trailers. The new trailers will be located near the north east corner of the property east of Building 60.
Circulation Study
Vehicular traffic flow patterns will not be affected by the proposed construction.
During construction, the existing gravel walking path will not be accessible. In the proposed conditions, the gravel path will be routed to and across the new parking lot to the east.
Pedestrians will cross the parking lot within a striped crosswalk and will be able to access the gravel path located on the eastern property boundary.
Phasing Analysis
The work related to the construction of the trailers and adjacent parking lot will not require phasing.
Parking Analysis
The construction of the new parking lot will result in the addition of 22 parking spaces which includes 3 accessible parking spaces and 3 bus parking spaces.
Storm Drainage
The existing gravel lot currently sheet flows to an existing inlet located near the north east corner of the lot. The existing inlet appears to tie directly into the triple barrel 5’x12’ reinforced concrete culvert located under the project area.
Drainage patterns will remain unchanged in the proposed conditions. The new parking lot will be constructed to drain to the existing inlet on site.
Water Utilities
The new domestic water line will connect to the existing 8-inch water line running east to west through the project area.

Project Overview
The Robert J. Dole VA Medical Center in Wichita, Kansas is renovating approximately 12,000 square feet on the ground level of Building 61 for Electronic Health Record Modernization
(EHRM) Training and Support Space.
The project scope for this area will include updating the interior wall and floor finishes, replacement of the existing ceilings, and replacement of all existing ceiling-mounted fixtures and equipment. The majority of the existing non-load bearing walls in this area will be demolished to reconfigure the area for administrative testing, training, and classroom activities. In addition to the renovation of space within Building 61, a lot located on the northeast side of the campus will be developed for new temporary trailers, which will provide administrative support services.

Interior Design Narrative
Painted gypsum board walls with insulation are utilized where acoustic privacy is needed between offices and meeting rooms. Ceilings in the project will be primarily suspended acoustic ceiling tile with gypsum soffits used strategically throughout for architectural elements and aesthetic accents. Acoustic ceiling tile will be selected with great attention to acoustic properties to control overall office noise and privacy in private offices. Commercial carpet tile will be used throughout the private offices, corridors, classrooms, and meeting rooms. Carpet tile with rubber backing and Nylon 6,6 fibers will help in maintaining the life of the carpet while allowing damaged tiles to be replaced as needed. Carpet will also aid in absorbing office noise and general sound from the surrounding environment. Luxury vinyl tile will be incorporated in the break room areas to provide a more cleanable flooring. New millwork in the breakroom will feature plastic laminate cabinet faces, solid surface tops and tile backsplash. Rubber base will be utilized throughout for a durable and cleanable solution. As the function of each space changes, demountable partitions will be featured to offer the client flexibility and noise control.
Restrooms will receive new porcelain tile floors and walls with gypsum board ceiling.
Bathrooms to be fully reconfigured to accommodate the increased number of users within the space. The restrooms will be made larger with increased fixtures and phenolic toilet partitions.
New countertops will be solid surface with plastic laminate apron. Material and finish aesthetic will be driven by campus standards.
Furniture and equipment are space-planned according to client design requirements.
All finish materials for this renovation will be evaluated based on their aesthetic appeal, durability, cleanability, and functionality.

B. There are two possible locations for the new air handling unit, the ground floor mechanical room and the roof. If the existing courtyard is filled in, there will no longer be a way to install large equipment into the mechanical room without it being modular and brought in through other parts of the building. The roof location does provide separate challenges with duct routing and pressure drops, since the project scope area is on the ground floor.
C. Onsite personnel have indicated possibility of third story expansion. If this is being considered, we recommend a new penthouse on the roof for the air handling unit could be provided then incorporated into the future expansion.

Communications Demolition
Basic Assumptions:
1. All existing data device in the area of work are fed from the Communication Room
005C.
Demolition of telecommunications work will include:
1. All conduits, surface raceways, data boxes and all data devices downstream of the IT racks within the area of work.
Points of Interconnection:
1. Data connections are generally compartmentalized so that removing conduit and cabling supplying the remodel area should not affect fixtures or devices in adjacent areas.
Building TR systems
Existing data in area of work is fed from Telecommunication Room 005C. There will be a separate EHRM facilities upgrade that will replace the existing 005C with a new TR in Room
006. All new data devices in this project will be connected into TR 006.
Building audio/visual systems
New equipment for the purposes of presentations and training will be integrated into the IT system.
General communications equipment
Cable Raceways, Pathways, Cable Trays, Cable Ducts, Conduits, and Boxes
1. All communications cabling will be CAT6A and routed in raceways or cable trays. Voice cabling will be terminated with RJ-45/11 jacks and data cabling will be terminated with
RJ-45 jacks.
2. Minimum raceway size for work area outlets will be 1.25”. Maximum conduit fill will not exceed 40%.
3. Minimum cable tray size will be 6” wide with 1.5” high sidewalls. Maximum cable tray fill will not exceed 40%.
Work Area Outlets
1. Work area outlets will consist of 4-11/16” x 4-11/16” x 2-1/8” boxes with double-gang, six-port faceplates. Each outlet will consist of (2) voice jacks, (2) data jacks, and space for future fiber-optic and coax cable jacks.
Telecommunications-3
Grounding and Bonding
1. Grounding and bonding will be provided in accordance with the NEC, VA PG-18-10 and
EIA/TIA Standards.
2. Any new metallic raceways, cable trays and basket trays will be grounded and bonded.
3. Any new equipment racks will be bonded to the TGB with a minimum #6 AWG stranded copper wire.
