iii. The Contractor shall submit a Badge Request to the COR for each worker scheduled to come on-site, at least two working days prior to the work scheduled. Three types of badges are issued by NASA.

The amount of information required, and the level of background investigation increases with the length of time a person requires access to ta NAS Center. Badge types are:

Visitor Badge – Required for any person visiting or working at a NASA Center (or combination of NASA Centers) for a cumulative total of less than 30 days in a calendar year.

Temporary Badge – Required for any person working at a NASA Center (or combination of NASA Centers) for a cumulative total of more than 30 days, but less than 180 days in a calendar year.

Hard Badge – Required for any person working at a NASA Center (or combination of NASA Centers) for a cumulative total of 180 days or longer in a calendar year.

iv. Temporary badges issued for regular working hours are not valid for work outside regular working hours. Work outside regular working hours requires a separate temporary badge request.

v. Employees shall wear and display the badge in the chest area at

SECTION 01 00 00 Page 12 all times while entering, remaining in, and exiting Ames. Each badge shall be used only by the specific individual named on the badge. Badged construction workers are authorized access only to the Project Site. They are not permitted to be outside the project boundaries except to perform contract work and to enter or leave Ames Research Center via the most direct route.

vi. Delivery truck drivers do not require badges if they have a valid U.S. State issued driver’s license and a printed bill of lading with the delivery location, building number and the name of the Contractor and recipient.

vii. The Contractor must maintain strict accountability over identification badges and passes issued by the Pass and ID Office.

Immediately report to the PASS and ID Office, any badges/passes missing or lost and the circumstances. Return badges/passes to the COR immediately upon termination of any employee, expiration, completion of contract, or when no longer required. The COR will ensure that all badges/passes are returned and forwarded to the PASS and ID Office.

3.4 WORK IN N254 COMMUNICATIONS FACILITY

The N254 facility must remain in full operation during the course of this construction. To mitigate the risk to communication services, NASA IT equipment, and NASA personnel the Contractor shall exercise particular caution and take steps to protect NASA personnel and equipment. The following requirements shall be met during construction within the facility:

a. Protection of personnel:

The Contractor shall provide warning signs, barriers and caution tape in areas where construction work is occurring to protect NASA personnel from construction-related injury. The Contractor shall be mindful of the other activities on-going in the facility and minimize the disruption to IT operations. When raised-floor panels are removed for under-floor access, caution tape and cones shall be placed to warn of the fall hazard.

b. Protection of IT equipment:

The Contractor shall protect the operating UPS and IT equipment in the area where construction is taking place from damage due to impact, dust and dirt, dislodging of cables, and overhead damage from falling debris. The Contractor shall protect under-floor and overhead cabling from damage in the work area.

c. Clean up:

At the end of each work day the Contractor shall remove all tools, materials and debris from the work area.

d. At the completion of the project, the Contractor shall thoroughly vacuum clean all Rooms where they performed work.

3.5 NASA MISSION FREEZE CONDITIONS

There may be occasions when on-site work must be suspended to accommodate launch, on-orbit maneuvers and other high risk events in which NASA will

SECTION 01 00 00 Page 13 issue a “freeze” directive to support facilities. During the “freeze”, all construction and/or modification work will cease in order to reduce the risk of an unplanned event that would impact the mission. The N254 facility is subject to these freeze events, which have a typical duration of 1 to 14 weeks. During these events all N254-related construction shall be suspended. NASA will provide the Contractor as much advanced notice as possible of freeze events and will make every effort to mitigate construction impacts.

3.6 BURROWING OWL HABITAT

Western burrowing owl habitat and an owl breeding preserve presently exist north and east of the N254/N254A fence lines. Development and construction activity at Ames is regulated according to the Burrowing Owl Habitat Management Plan (BOHMP). Where there is a discrepancy between the BOHMP and these notes, the BOHMP takes precedence.

Pursuant to the BOHMP, the project is governed by the following:

a. No permanent development or temporary construction activity is permitted within the preserve to avoid impacts to owls.

i. Impacts to owls include disturbance within 160 feet of an occupied burrow, destruction of an active burrow, or destruction/degradation of foraging habitat within 300 feet of an occupied burrow.

ii. To avoid "take" under the Migratory Bird Treaty Act and CDFG Codes, disturbance of active nesting territories should be avoided during the breeding season, from March 1 to August 31.

iii. To avoid impacts, disturbances must be 160 feet from occupied burrows during the non-breeding season and at least 250 feet away during the breeding season.

b. Equipment will not be staged within any preserve.

c. Surveys will be done within 1-2 weeks before starting any construction activity, including staging equipment. NASA will provide a qualified wildlife biologist to survey for occupied burrows upon request.

d. In the event that an occupied burrow or active nest is found within the relevant buffer, NASA will provide a qualified on-site biological monitor to ensure that disturbances do not cause burrow or nest abandonment. Biological monitor may use standard methods, including temporary stop-work and changing the work schedule to avoid times of day most likely to affect owls. The Contractor will coordinate monitoring schedule with Chris Alderete by phone at 650-604-3532 or by email at christopher.s.alderete@nasa.gov.

e. During the breeding season, if an occupied burrow is found within the 250' buffer, work may be delayed until the NASA wildlife biologist determines that nestlings have fledged.

3.7 AIR EMISSIONS INFORMATION DURING CONSTRUCTION

The Contractor shall submit, annually (within the performance period) and upon request by the Contracting Officer (CO), information on construction
