- Description
- Department of Veterans Affairs Traumatic Brain Injury (TBI) Center Northern California Health Care System (NCHCS) City of Martinez State of California Project No. 612-905 Estimated Price Range is between $5,000,000 and $10,000,000. Design-Build. Competitive Negotiated Acquisition (Source Selection) (IAW FAR Part 15.3) RFP to be issued electronically at FBO Website RFP Issue Date: 31 July 2008 Proposal Due Date: 31 August 2008 Scope of Work: Work includes the construction for a new building in accordance with the design drawings and specifications. Narrative of Building Systems Architectural Exterior: This two-story building has two main points of entry. One entry is at grade level from the existing CREC building and the second is the main visitor's entry from the adjacent parking lot. The exterior materials are similar to the CREC: stucco 5:12 roof pitch- standing seam metal roof, window bays along the east side match the window bays of the existing patient rooms. The curved wall is a unique feature to this building; the wall has a masonry veneer finish similar to masonry on other campus buildings. The covered walkways have similar proportions to the covered breezeway connecting to the main entrance of the CREC. An enclosed walkway connects the Shasta wing to the ground floor gym entry and a roof-covered walkway connects to the existing Tahoe wing. Another distinctive feature is the curtain wall design enclosing the two story gym space. Our goals in shaping the roof form include simplifying the truss layout, complimenting the curved wall on the west and reflect the CREC roof shape on the east side of the building. Solar Tubes are incorporated along the main corridor axis of the second floor to bring natural light into the center of the building, reducing lighting loads. Architectural Interior: The quality of this space at the main entry and the gym sets the tone for the Veteran's experience in their recovery. We designed this space as the centerpiece for the user whether they enter at the second level reception area or at the first level gym. The connecting stairway is glass enclosed with a locking vestibule to provide security to the second floor during non-office hours. Building Site: Another significant feature of the building form that responds to the limits of the building site is the exterior west wall. This wall curves to follow the sidewalk bend along the parking area. To take advantage of the sloping grade, the lower level exterior west wall is offset by 8 feet. This offset is a significant design element because it eliminates the need for a full height (11 feet) retaining wall for the entire length of the 160 foot building; that's a lot of concrete! The building section illustrates this concept. Preliminary Soils Report: On June 27, 2008 the soils engineer drilled five test borings at the site. One boring was located roughly at each of the four corners of the planned roughly rectangular shaped building and the fifth boring was located near the center of the proposed building footprint. For purposes of this narrative, I refer the borings at the corners nearest the existing Shasta Building as the "lower borings", the borings at the other two corners of the building (drilled from the shoulder of the existing road/parking area) as the "upper borings" and the boring at the center of the building as the "center boring". All borings encountered severely to completely weathered sandstone and/or siltstone bedrock materials at depths of less then 8 feet. The sandstone was relatively weakly cemented, but is very dense (blow counts in excess of 50 for 3 inch penetration). In the lower borings the top of weathered rock was encountered at a depth of approximately 3 to 4 feet and was overlain by relatively dense sandy soils. In the middle boring the sandstone was encountered at a depth of about 2 feet. The upper borings were drilled just off the road shoulder and encountered approximately 5 to 6 feet of fill soils. The weathered bedrock material was encountered at a depth of approximately 7 to 8 feet in the upper borings. The fill appears to be moderately well compacted and is compromised of a mixture of yellow brown sand and dark brown silty to sandy clay. Based on the borings, the materials underlying the site are relatively competent and suitable for the new building construction. In my opinion the new building can be supported either on conventional spread footings founded in the weathered rock layer or on drilled piers. Preliminary architectural plans show the building benched partially into the hillside. Cuts within the building footprint should expose competent material and I would expect a temporary cut slope of 1:1 (20 feet or less in height) made during the dry weather period would be reasonable. Conventional building retaining wall pressures are anticipated. It is assumed the walls will be designed with back drains to limit hydro static forces. Soils/weathered rock anticipated at slab level are not anticipated to be expansive and conventional slab-on-grade construction is anticipated to be acceptable. For seismic design in accordance with the 2006 IBC/2007 CBC we will likely be recommending a Type C profile. Structural system: The foundation for the building will be grade beams resting on drilled piers or a spread foundation depending on the geotechnical report recommendations. The depth of the footing and piers will be established by the geotechnical report. Concrete strengths would be in the range of 3000 to 4000 psi at 28 days. The structural frame for the building is expected to be a steel beams and columns, braced by a concentrically braced frame system for seismic & wind lateral loading. Interior partitions and exterior wall framing will be steel studs. The floor and roof system will be a composite concrete and steel deck system. We do not recommend the use of a plain metal deck for the roof diaphragm. Mechanical System: Mechanical System for the building consists of split DX system with high efficiency condensing unit outdoors and high efficiency condensing gas furnace indoor unit. Dehumidification unit for the lap-pool room shall be a split system with remote condenser. Dehumidification system shall be designed to preclude condensation in the lap-pool room. Equipment shall be high efficiency and shall be capable of providing minimum two LEED credits under Optimize Energy Performance and one LEED credit under Enhanced Refrigerant Management. Toilet exhaust fan shall be provided for the Men/Women rooms with minimum 10 air changes per hour. Building management system shall be direct digital controls extended from existing hospital control system. Electrical System: The project will provide feeder trenching, conduits, and transformer for the new service for the new two-story medical office building. The main building switchgear will feed 480Y/277 volt distribution panels. The distribution panels will feed dry type 480-208/120 volt transformer located in the electrical room. These transformers will feed 208Y/120 volt secondary distribution panels. A complete wiring system will be provided to distribute power to all equipment and devices, including receptacles, lighting fixtures, elevators, mechanical equipment, and etc. Grounding system will be designed in accordance with CEC article 250 and will be based on equi-potential grounding with voice/data system bonded to the building ground system. A complete lighting system shall be provided for the building. Indoor lighting shall consist primarily of energy-efficient fluorescent fixtures. In general, indoor lighting will be controlled by lighting control system and room occupancy sensors. Emergency/night lighting will be provided by unswitched branch circuits. These unswitched branch circuits will be fed from emergency lighting panels. PVC conduits will be run from the service provider duct banks to the Main Voice/Data Equipment Room (VDER). The voice data system will consist of wall outlets in all building spaces and connected to the nearest VDER via a single conduit. Fire alarm system shall be electronically multiplexed voice communication system matching existing VA fire alarm system. Remote transponder panels will be used to provide supervised amplifiers and signal circuits for audio/video devices and magnetic door holders. The system will utilize individual addressable photoelectric smoke detectors, addressable manual pull stations and addressable monitor and control modules. The system will monitor all sprinkler supervisory and water flow switches and shall interface with elevators, HVAC smoke control and smoke fire dampers. Plumbing System: Potable hot and cold water shall be provided for Men/Women rooms, examination rooms, laboratories, showers, and miscellaneous sinks throughout the building. Building water distribution shall be isolated from the city water system by providing a reduce pressure backflow preventer. Sanitary waste and vent piping shall be provided for potable waste producing fixtures and equipment, with all fixtures trapped and vented to atmosphere. Natural gas shall be distributed through the building to gas fired mechanical equipment and the domestic water heater. All plumbing systems shall be designed per the International Plumbing Code. Fire Sprinkler System: The building shall be provided with area-wide hydraulically calculated wet pipe fire sprinkler system conforming to NFPA 13 and the International Fire Code. Site utilities and grading: There will be moderate amounts of grading at the site to accommodate the building and walkways and access points for the new facility. Some retaining walls will required at the south portion of the building as well as the east and west walls. Nearby, onsite main utilities are available for hook-up including sewer, water, storm drain, and subsurface drainage. The sizes and locations of the existing onsite utilities appear to be adequate for connection to the new building. Landscaping Limited budget is required for landscaping. Address the areas between parking lot, sidewalk and new building and the area between Shasta Wing and Tahoe Wing of the CREC building shall be addressed. A patio area serving the Clubhouse functions is desired for outdoor BBQ area. Repair and replant damaged areas caused by construction. The landscaping materials and design standards shall follow the existing NCHCS landscaping standards.
