3.1.5.5.2.2 Simulating Conditions

Over-writing control input values through the controls system is not acceptable, unless approved by the Contracting Officer's Representative .

Identify proposed exceptions in a protocol submitted to the Contracting Officer's Representative for approval. Before simulating conditions, overwriting values (if approved), or changing set-points, calibrate all sensors, transducers and devices. Below are several examples of exceptions that would be considered acceptable:

a. When varying static pressures inside ductwork can not be simulated within the duct, and where a sensor signals the controls system to initiate sequences at various duct static pressures, it is acceptable to simulate the various pressures with a Pneumatic Squeeze-Bulb Type Signaling Device with gauge temporarily attached to the sensing tube leading to the transmitter. It is not acceptable to reset the various set-points, nor to simulate an electric analog signal (unless approved as noted above).

b. Dirty filter pressure drops can be simulated using sheets of cardboard at filter face.

c. Freeze-stat safeties can be simulated by packing portion of sensor with ice.

d. High outside air temperatures can be simulated with a hair blower.

e. High entering cooling coil temperatures can be used to simulate entering cooling coil conditions.

f. Do not use signal generators to simulate sensor signals unless approved by the Contracting Officer's Representative , as noted above, for special cases.

g. Control set points can be altered. For example, to see the air conditioning compressor lockout work at an outside air temperature below 55 degrees F, when the outside air temperature is above 55 degrees F, temporarily change the lockout set point to be 0 degrees F above the current outside air temperature. Caution: Set points are not to be raised or lowered to a point such that damage to the components, systems, or the building structure and/or contents will occur.

h. Test duct mounted smoke detectors in accordance with the manufacturer's recommendations. Perform the tests with air system at minimum airflow condition in ductwork.

i. Test current sensing relays used for fan and pump status signals to control system to indicate unit failure and run status by resetting the set point on the relay to simulate a lost belt or unit failure while the unit is running. Confirm that the failure alarm was generated and received at the control system. After the test is conducted, return the set point to its original set-point or a set-point as indicated by the Contracting Officer's Representative .

SECTION 01 91 00.15 Page 15

3.1.5.5.2.3 Setup

Re-test to the extent necessary to confirm that the deficiencies have been corrected without negatively impacting the performance of the rest of the system.

3.1.5.5.5.2 Less than 100 Percent Sample

For systems tests with a sample size less than 100 percent, if one or more of the test procedures for an item of equipment or a system results in discovery of a deficiency, regardless of whether the deficiency is corrected during the sample tests, the item of equipment or system fails the test.

a. If the system failure rate is 5 percent or less, meaning that 5 percent or less of the equipment or systems had at least one deficiency, re-test only on the items which experienced the initial failures.

b. If the system failure rate is higher than 5 percent, meaning that more than 5 percent of equipment or systems tested had at least one deficiency, re-test the items which experienced the initial failures to the extent necessary to confirm that the deficiencies have been corrected . In addition, test another random sample of the same size as the initial sample for the first time. If the second random sample set has any failures, re-test those failed items and all remaining equipment and systems to complete 100 percent testing of that system type.

3. Additional site visits were conducted throughout the design phase until the submittal of this 100% package. Site visits were conducted by various discipline personnel, including architectural, mechanical, electrical and plumbing, hazardous material, and telecommunication consultants.

H. Security Provisions/Force Protection:

1. Per the new UFC 4-010-01, 1-15.1, the first step in planning antiterrorism requirements is for the Installation (JBSA FSH 502d CES) to determine the Design Basis Threat (DBT), which is specific to each facility. As of the writing of this narrative, it is believed that the Installation has yet to conduct the analysis of this facility that would identify the DBT. In the absence of any threat-specific requirements, the design will assume compliance with only the minimum standards identified in the UFC.

2. Analysis

a. This renovation is under 50 percent of the plant replacement value of this building, thus, implementation of the UFC standards to bring the entire building into compliance is recommended but not required.

b. Standard 1 – Standoff Distance

1) Minimum Standoff: 20 feet to installation perimeter required; 136 feet actual condition

2) Minimum Clear Zone: 50 feet required; >50 feet actual condition

c. Standard 2 – Unobstructed Space

1) Minimum Unobstructed Space: 33 feet required/>33 feet actual

2) Equipment pads and/or trash containers will be located outside the unobstructed zone

d. Standards 3 through 9 – These standards are either not applicable to this project or have been eliminated from the UFC.

e. Standard 10 – Glazing

1) Minimum glass required: 1/4-inch laminated glass, inclusive of 0.030 PVB interlayer.

Glazing proposed will be 1 inch insulated glass unit (IGU) with the inboard lite consisting of 1/4-inch laminated glass meeting the requirement of the UFC.

f. Standard 11 – Building Entrance Layout

1) Existing building entrances face the perimeter fence, which is >136 feet to the east.

No change to building entrance location is possible or proposed.

g. Standard 12 – Exterior Doors

1) All exterior doors will swing outward, in the direction of egress; all glazing will comply with Standard 10.

h. Standards 13-15 – These standards are not applicable to this project due to exemption.

i. Standard 16 – Air Intakes

1) All new air intakes will occur through the existing roof-mounted cupola, over the high portion of the building. Consequently, all intakes will be well above 10 feet above adjacent grade.

j. Standard 17 – Mail Room/Loading Dock Ventilation: This standard is not applicable to this project.

k. Standard 18 – Emergency Air Distribution Shutoff

1) HVAC controls will provide emergency shutoff switch to comply with the UFC.
