QUESTION 7: Are all irrigation controllers functional with internet capability for programming (manufacturer's names/models)?

RESPONSE: Irrigation systems have a database program that is not authorized to be on the Base internet system. Computer is available at shop.

QUESTION 8: Will irrigation repair be required at missile pads?

RESPONSE: Irrigation repair will be required at all locations on Vandenberg AFB where irrigation systems are located and base property.

QUESTION 9: Are irrigation supply lines for repair deeper than 4 feet, thus requiring shoring?

RESPONSE: Irrigation systems are located at various depths on Vandenberg AFB, thus requiring shoring if a system is identified deeper than 4-feet or excavation needs to be stepped out.

QUESTION 10: What irrigation restrictions, if any, are currently in place by the water vendor company for VAFB? Do any areas of the base have an irrigation variance for "critical need cosmetics"?

RESPONSE: The base has identified areas that are listed as cosmetic areas for DV visits and tours.

The main gate all the way up California Avenue to the Base Headquarters 10577 and around the Pacific Coast club, along with the Missile V location.

QUESTION 11. Are accurate blueprints available on CD or on-line for irrigation schematics?

RESPONSE: The WFSM shop has maps that were given to them from the previous irrigation contractor and will provide them to the Program manager upon request.

QUESTION 12. In addition to Base Safety (SE) and Civil Engineering, which other entities would interface with the irrigation contractor for trenching?

RESPONSE: Any work in regards to trenching, digging or breaking ground or shutting down systems would have to be coordinated through Base Safety, 30 Civil Engineer Squadron, 30 Civil Engineer Environmental flight, and possible Balfour Beatty housing (if backflow is a dual system which some are).

QUESTION 13. What is the percentage of manpower devoted to hand watering brown spots in turf, and approximately number of acres of turf affected by this problem? Are there hose-bibs available for this task or is a water truck required?

RESPONSE: The base has a lot of areas that require manual backflows and valves to be turned on for watering. Currently, since we are in a drought the majority of areas on base have been turned off and not maintained until the grass is deemed dying. Brown is good, grey is bad.

QUESTION 14. What did this previous contract bid for including any extenuating change orders?

RESPONSE: Do not have an answer for this question

QUESTION 15. Does this contract require grounds maintenance beyond the scope of irrigation?

RESPONSE: This contract will be specifically for the irrigation, but any trenching, digging or relocation of sprinklers should have the contractor repair the surface to the original design. Cradle to Grave.
