WORK RESTRICTIONS

Special Scheduling Requirements:

Have materials, equipment, and personnel required to perform the work at the site prior to the commencement of the work.

The Contractor shall conduct operations so as to cause the least possible interference with normal operations of the activity.

Permission to interrupt any activity roads, railroads, and/or utility service shall be requested in writing a minimum of 15 calendar days prior to the desired date of interruption.

Flight Line Driver’s License:

Personnel driving on the flight line will be required to get a NAS Corpus Christi Field flight line driver’s license. Coordinate with the COR.

Contractor Employment Eligibility Verification:

Contractors and subcontractors are required to abide by Department of Homeland Security requirements for verification of worker employment eligibility. This is in support of detection and apprehension of illegal alien/undocumented workers. To this end, base access procedures for badge issuance include on-site verification of base sponsorship and supporting documentation. The Government has implemented DBIDS base access procedures. Under DBIDS, employee badges may be obtained either by visiting the Pass and ID Office daily or utilizing the DBIDS Program. The cost of the RAPIDGate program includes a fee for the Contractor's firm and a fee per Contractor employee for use of the program. Contractors who choose not to participate in the program will be required to obtain daily business passes at the pass office. Badges/passes are the property of the Government and must be displayed as required by the Installation Security Department. RAPIDGate badges remain the property of DBIDS, and as such must be returned within two calendar days to the employer when an employee leaves the Contractor's service. It is the sole responsibility of the Contractor to see that all badges issued to their employees are returned in accordance with these provisions. Upon expiration of the contract, all employees' passes and badges shall be deactivated and the base access privileges revoked until such time base access is again required/authorized. Due diligence on your part in screening employees is required because the Government is not responsible for work Delays or Stoppages caused by the Contractor/sub-contractor's failure to comply with registration and access requirements, nor is the Government responsible for program fees lost due to ineligible personnel. Also be aware, that the Contracting Officer is required to consider debarment proceedings where repeated or egregious violations of access control requirements are found. In addition to these provisions the Contractor shall also comply with all additional base procedures for applying to obtain commercial passes for entry to this facility. To obtain additional information regarding base access, please contact the pass and ID office at 361-961-1356.

It should be recognized that requirements for security and base access varies between bases as well as between various locations within individual bases. It is incumbent on the Contractor to ascertain the current security and base access requirements appropriate to the project location and incorporate the cost, if any, for compliance to said requirements into Contractor's proposal. Lack of knowledge of current requirements does not constitute a basis for an adjustment to the contract. Should requirements change during the construction timeframe, Contractor may be eligible, subject to documentation acceptable to the Government, for an adjustment to the contract.

Ensure that Contractor personnel employed on the Activity become familiar with and obey Activity regulations including safety, fire, traffic and security regulations. Keep within the limits of the work and avenues of ingress and egress. Wear hard hats in designated areas. Do not enter any restricted areas unless required to do so and until cleared for such entry. The Contractor's equipment shall be conspicuously marked for identification.

Subcontractors and Personnel Contacts.

Furnish a list of contact personnel of the Contractor and subcontractors including addresses and telephone numbers for use in the event of an emergency. As changes occur and additional information becomes available, correct and change the information contained in previous lists.

No Smoking Policy.

Smoking is prohibited within and outside of all buildings on installations except in designated smoking areas. This applies to existing buildings, buildings under construction and buildings under renovation. Discarding tobacco materials other than into designated tobacco receptacles is considered littering and is subject to fines. The COR will identify designated smoking areas.

Working Hours:

Working hours will be coordinated with the COR at NAS Corpus Christi.

1.2 DEFINITIONS

1.2.1 Landing Areas:

"Landing Areas" means:

a. The primary surfaces, comprising the surface of the runway, runway shoulders, and lateral safety zones. The length of each primary surface is the same as the runway length. The width of each primary surface is 1500 feet (750 feet on each side of the runway centerline).

b. The "clear zone" beyond the ends of each runway is the extension of the primary surface for a distance of 3000 feet beyond each end of each runway.

c. All taxiways, plus the lateral clearance zones along each side for the length of the taxiways (the outer edge of each lateral clearance zone is laterally 250 feet from the far or opposite edge of the taxiway (example: a 75-foot-wide taxiway shall have a combined width and lateral clearance zone of 425 feet.)

d. All aircraft parking aprons, plus the area 125 feet in width extending beyond each edge all around the aprons.

1.2.2 Safety Precaution Areas:

“Safety Precaution Areas” means those portions of approach-departure clearance zones and transitional zones where placement of objects incident to contract performance might result in vertical projections at or above the approach-departure clearance, or the transitional surface.

a. The “approach-departure clearance surface” is an extension of the primary surface and the clear zone at each end of each runway, for a distance of 50,000 feet, first along an inclined (glide angle) and then along a horizontal plane, both flaring symmetrically about the runway centerline extended.

(1) The inclined plane (glide angle) begins in the clear zone 200 feet past the end of the runway (and primary surface) at the same elevation as the end of the runway. It continues upward at a slope of 50:1 ((1) one foot vertically for each 50 feet horizontally) to an elevation of 500 feet above the established airfield elevation. At that point the plane becomes horizontal, continuing at that same uniform elevation to a point 50,000 feet longitudinally from the beginning of the inclined plane (glide angle) and ending there.

(2) The width of the surface at the beginning of the inclined plane (glide angle) is the same as the width of the clear zone. It then flares uniformly, reaching the maximum width of 16,000 feet at the end.

b. The “approach-departure clearance zone” is the ground area under the approach-departure clearance surface.

c. The “transitional surface” is a sideways extension of all primary surfaces, clear zones, and approach departure clearance surfaces along inclined planes.

(1) The inclined plane in each case begins at the edge of the surface.

(2) The slope of the incline plane is 7:1 ((1) one foot vertically for each (7) seven feet horizontally). It continues to the point of intersection with the —

(a) Inner horizontal surface (which is the horizontal plane 150 feet above the established airfield elevation); or

(b) Outer horizontal surface (which is the horizontal plane 500 feet above the established airfield elevation), whichever is applicable.

d. The “transitional zone” is the ground area under the transitional surface. (It adjoins the primary surface, clear zone, and approach-departure clearance zone.)
