D. Design Changes

Following the completion of the 95% design, the following changes were requested by the Users, and were deemed as changes that would require additional funds (please note that these changes may be requested to be completed in the construction phase of the project):

The dimensions of Rooms 116, 117 and 118 in the building have been requested to be changed from the 100% design.

Room 116 has been requested to become the FMS Equipment & Tool Storage room and be approximately 346.8 square feet in size.

Room 117 has been requested to become the Gen Flight Supt Office and be approximately 175.7 square feet in size.

Room 118 (Gen Flight CC Office) has be requested to be resized to approximately 205.9 square feet.

All three of the above rooms have been requested to have doors that open to

Corridor 114 (with Room 116 having double doors).

With these changes to the scope, it may require additional changes to the HVAC (to move diffusers, re-calculate airflows, and rearrange ductwork as needed), the Electrical

(for new locations for data/comm and outlets), and the Lighting for these three rooms

(including lighting calculations).

SECTION 3 CIVIL AND SITE WORK

A. Existing Site Description

Existing Condition: The building site (Site), existing building 8314, is located at

Vandenberg AFB north of 8th Street, east of Nevada Avenue, south of 6th Street and west of New Mexico Avenue. The Site contains the existing building, existing parking areas, roads, sidewalks, utilities, and general landscaping.

B. Grading

The area adjacent to the access door at Room 113 will be re-graded to provide positive flow away from the building.

C. Parking

This project will not provide additional privately owned vehicle (POV) parking. A portion of the government owned vehicle (GOV) parking on the north side of the building will be re-striped to restrict parking adjacent to the existing fire hydrant. The odd shaped concrete pad located outside Room 124C's double doors will be removed and replaced with a new rectangular 14' long by 10' wide concrete pad.

D. Storm Drainage

1. Existing Storm Drainage

Existing storm water drainage in the project area primarily consists of sheet flow and surface drainage. The area on the west side of the building slopes toward the building allowing water to enter the building at the access to the overhead door at

Room 113.

2. Proposed Storm Drainage Improvements

Site grading will incorporate a positive slope away from the building. The existing asphalt and concrete pavement in the area will be removed, the area will be re-graded, and new pavement will be placed to convey storm flows away from the door.

E. Utilities

1. Water Supply and Distribution

This project will not alter any existing water supply and/or distribution lines or provide any new water lines. New bollards will be installed to protect the existing fire hydrant located on the Building's northeast side, near the exterior staircase.

2. Sanitary Sewer

This project will not alter any existing sanitary sewer lines or provide any new sewer lines.

3. Gas Distribution

This project will not alter any existing gas lines . A new gas line will be provided from the building to the new barbeque pavilion area.

4. Power and Telecommunications Distribution

Refer to Section 9 for power and telecommunications site work.

5. Monitoring Wells, Injection/Extraction Wells and Buried Pipelines

This project will not alter any existing monitoring wells, injection/extraction wells or associated buried pipelines and items shall not be disturbed during construction.

F. Fencing, Screen Walls, and Security Walls

The existing chain-link fencing gate leading to the parking lot on the west side of the building will have its hinges removed and replaced.

G. Landscape Design

The trees that are currently touching the northeast perimeter fence will be pruned. The tree that has grown into the northwest perimeter fence, just off the south corner of

Building 8314's north parking lot will be removed. Trees being pruned or removed shall be done outside of the nesting bird season (February 15 to August 15), if this cannot be done, contact Natural Resources to survey the trees. If nesting birds are found, work may be delayed until the young have fledged. The same applies to any nest that may be found on the building. Any questions contact Rhys Evans. 606-4198

The grassy area located on Building 8314's northeast end will be developed with new landscaping and a barbeque area.

C. Building Code and Life Safety Analysis

Required Codes: UFC 3-600-01 Fire Protection Engineering for Facilities UFC 1-200-01 General Building Requirements NFPA 101 Life Safety Code, 2012 edition NFPA 1 Fire Code NFPA 10 Portable Fire Extinguishers

IBC 2009 International Building Code UFC 3-420-01 Design: Plumbing Systems

General This project is an Alteration under provisions of IBC 3404.

This requires alterations to comply with the current code so that the unaltered portions of the facility remain no less compliant to code than as previously constructed. In addition, under UFC 3-600-01, 1-3.2.2, this project cost is far less than the 50 percent of replacement cost threshold.

As such, the minimum code requirements for the unaltered portions are the NFPA 101 requirements for existing facilities.

Several storage rooms are identified as “hazmat”. The actual nature of hazard must be determined as this could have significant impact on code compliance provisions. For the present evaluation, these areas are assumed to be ordinary hazard storage.

Assembly occupancy is present due to Conference Room 115 on the Ground Floor having over 50 occupant load.

This room exists and is unaltered, therefore will not impose requirements of new construction on the building.

Fire Dept. Access: Maximum 33 feet from building. (UFC 3-600-01, 2-10) Any part of exterior wall not more than 150 feet from access roads; minimum access road width 20 feet; dead-ends more than 150 feet require turn-around for fire dept.

vehicles. (NFPA 1, 18.2.3.2)

Building Floor area: 39,371 SF Ground Floor; 8,962 SF Second Floor (IBC 502.1). Height = 33 feet, two stories

Occupancy Type: Mixed, non-separated:

NFPA 101 Chapter 13 Existing Assembly, Chapter 38 New Business, Chapter 39 Existing Business; Chapter 40 Industrial, Chapter 42 Storage

IBC A-3, B, F-1 and S-1 (note that there are several rooms identified as “Hazmat” which may require an H occupancy classification)

Construction Type: IBC Construction Type VB, with Full Sprinkler System (Table 601)

Required Fire Ratings: IBC Table 601 requires no fire ratings. Construction type includes wood framed partitions. For exterior walls, the actual minimum separation is 22.5 feet (45 ÷2). Required horizontal separation for which no wall protection is required is 10 feet per IBC Table 602 (If H occupancy applies, for less than 30 feet separation, one hour exterior construction is required).

Basic Allowable Floor Areas: IBC Table 503 basic area 6,000 SF, 1 Story, 40 feet height (not considering the possibility of H occupancy).

IBC Floor Area Increases: Increase due to sprinklers = 200 % Area (IBC 506.3); one additional story and additional 20 feet height (IBC 504.2) Increase due to open perimeter = [525÷570-0.25] x 30÷30 = 0.67 Total Allowable Area = 6000 + [6000 x 0.67] + [6000 x 2] =

22,053 SF (IBC 506.1)

Due to shortfall of allowable floor area, the building would be required to be subdivided by a 2-hour fire wall (IBC 706). The wall along F.3 between the maintenance bay and the corridor/stair is recommended for this treatment.

Note: because this project is an alteration, the requirement for area separation does not apply.

Building Height: IBC Table 503 basic height 1 Story, 40 feet; increase 20-feet and one story for sprinklers or 2 stories and 60 feet

D. General Building Description

1. Building 8313 is a two story structure; approximately 48,736 SF built in 1960. The building is constructed of block wall, poured in place concrete, and steel framing with corrugated metal wall panels with exposed fasteners on the exterior. The exterior work shall consist of replacing some of the doors, windows, louvers and metal panels in areas of unsightly wear and existing damage. The lean-to structure on the northeast side of the high bay structure will not receive any work apart from some minor exterior repair to the exterior metal panels.

2. Existing interior wall finishes include; gypsum board and painted CMU walls with floor finishes that include carpeting, resinous coating, ceramic tile and vinyl tile.

Existing ceilings are either suspended 2’x4’ acoustical tile or metal framed gypsum board. The existing suspended acoustical ceiling systems shall be replaced in areas of wall demolition and replaced with matching, new 2’x4’ acoustical tile system. Some intersecting corridor areas will include suspended gypsum board bulk heads in the ceiling to provide a termination point for different ceiling grid layouts.

3. AT/FP standards are used in the specification of windows, window frames, curtain wall and glazing and their connections to structure. Windows are fixed with heavy aluminum framing with minimum 70 percent polyfluorovinylidine bronze finish to match the roof and trim color. The windows are glazed with 1 inch thick insulating units. The outer pane is gray tinted, low-e coated, ¼ inch thick, heat strengthened glass. There will be an inter-layer of ½ inch dehydrated air. The inner pane is nominal 1/4 inch, clear laminated glass.

Interiors

SECTION 5 INTERIORS

A. General

Excellence in interior design and meeting the requirements outlined in the scope of work are the primary goals for the project. The design shall incorporate and include applicable building codes/regulations and LEED responsible material resourcing.

The Structural Interior Design package includes the selection, specification and coordination of interior finishes and equipment that are integral to or attached to the building structure. The general interior features that are within this scope-of-work are: replacement of some walls, wall finishes, floor finishes, ceilings, trim, doors, door frames, door hardware, installed equipment, light fixtures, plumbing fixtures and signage as outlined in the concept drawings provided by Vandenberg AFB. All products shall be specified to comply with all applicable building codes and regulations as stipulated in the project scope of work. The documents required to articulate the Structural Interior Design intent and the specific details include:

Architectural Floor Plans, Interior Finish Plans, Signage Location Plans, Interior Elevations, Schedules, Legends, and Details. Written product specifications and physical samples are keyed to the drawings and other documents for reference. All necessary submittal documents, construction document drawings, details, Interior Elevations, Interior Finish

Selections, Specifications, coordination, RFP response, cost controls and adherence to the budget for the Interior Design of this project, are being provided by and all responsibilities assumed by the Owner.

B. STRUCTURAL INTERIOR DESIGN (SID) INTENT:

The design intent is based upon discussions with the end-user regarding their functional needs to support the mission. The end-user selected conceptual design intent for the interior finishes color scheme. The color scheme acts as a psychological counterpoint to the end-user’s mission. Neutral wall colors balance the saturated accent colors and maintain a professional atmosphere. Dark neutral floorcoverings with bright accent colors create visually stimulating patterns and are low maintenance. The industrial/technological environment is continued in the administrative and ancillary support areas with the same color-palette and limited use of saturated colors. Practical and durable material selections withstand the

Interiors physical demands of the mission and reflect the specific functional requirements of each space. All materials are low maintenance and have high ROI through their life-cycle cost.

Areas that are subject to high-abuse/wear have appropriate hard-wearing finishes include solid vinyl tile and/or porcelain pavers, high-abrasion-resistant paints and specialty coatings, special wall-guard coverings and corner guards. Administrative/office areas have solution-dyed modular carpet, abrasion-resistant paint and corner guards. Rubber cove base is specified for solid vinyl tile flooring and epoxy floor paint. Carpet base is specified for areas receiving carpet flooring. Porcelain base is specified with porcelain paver floors. Restrooms have solid surface counter tops, ceramic tile wainscoting and stainless steel toilet accessories. All interior design finishes will be selected by the Owner who has assumed all responsibility for their ability to perform and meet all design criteria established by the Design

Guidelines.

9. Ventilation System

The existing building is provided with ventilation air, and it is assumed to meet the minimum requirements of ASHRAE Standard 62.1. Because the building occupancy will not increase, it is assumed the current ventilation provided by the existing variable air volume system is sufficient and will not need to be increased.

The exhaust fan serving the existing restroom system will be replaced.

The PREL laboratory has been designed for a storage ventilation rate per

ASHRAE Standard 62.1 as air classification 4. Per the information provided, the design assumes the chillers tested in the room will have a total quantity R-22 and

R-134a under the threshold for the requirements of a machinery room per

ASHRAE and the IMC.

The equipment and tool storage rooms (107, 119, 124C) have been designed for a storage ventilation rate per ASHRAE Standard 62.1 as air classification 4. Air class 4 air shall not be recirculated or transferred to any space nor recirculated within the space of origin. A dedicated exhaust fan for the rooms that is spark proof and explosion proof is provided. The makeup air for the rooms shall come from the adjacent spaces ceiling plenum. Exhaust fans shall run 24 hours per day, 7 days per week and shall signal an alarm if de-energized due to failure.

10. DDC Systems

New equipment will be connected to the existing Direct Digital Control (DDC) system.

B. HVAC System

The existing, non-operational heating and ventilating unit HV-1, shall be removed. The

PREL laboratory shall be provided with a new dedicated, split system heat pump.

Multiple evaporative units in combination with heat pumps will provide conditioned air to the room. The heat pump units located outside next to the building will have an anticorrosion treatment to protect against salt corrosion.

The remaining spaces that were served by HV-1 (Room 107, Room 119, Room 120, and Room 124C) shall be served by a new heating and ventilating unit.

The new offices and FMS storage (Room 116, Room 117 and Room 118) will be conditioned by the existing variable volume Air Handling Units (AHUs). A new VAV terminal unit will be provided for these offices.

To evaluate the cooling provided in Room 110, per the statement of work, a heat gain calculation was completed for the room. The calculation assumed that the heat gain from the 500 kVA transformer located in the room was 25 Watts per kVA. The results of the calculation indicated that the current airflow provided to the room from the existing

VAV system would be sufficient for cooling the equipment as required.
