ITEM # TOPIC

1 BIDDING PROCESS

This is the pre‐bid meeting for the D1/D4 Water Systems Recovery Act project. The information presented here today will be taken directly from the documents supplied on the fbo.gov website. Any information that is new or different will be posted after this meeting at that same website. Specific questions about how the bids will be evaluated and awarded should be directed to the Contract Specialist listed on the website – Tanjia Harris‐Davis. All bids are due June 21, 2010, in electronic form, by 2 pm Pacific time.

Field visit today will include review of three of the projects in the package: Arcadia Campground, Riggs Flat Recreation Area, and Columbine Administrative Site. If there are questions on the other project (Cochise Stronghold Tank), we can entertain those today as well, but a site visit is not scheduled for that site.

Concrete valve boxes assumed by location only – numbers will be modified to accommodate depths as well.

7 QUESTIONS AND ANSWERS

a WHO HANDLES THE PERMITTING FOR THIS PROJECT? Any permitting required to complete the projects is the responsibility of the Contractor.

b CAN THE LINE ITEMS BE CODED SO THAT WE UNDERSTAND WHICH WELL DRILLING ITEMS ARE ASSOCIATED WITH A SUCCESSFUL OR UNSUCCESSFUL WELL? Yes, the Schedule of Items has been revised.

c IS MOVING THE ARCADIA TANK LOCATION AN OPTION? Please assume that the tank location does not move.

d WHAT IS THE FURTHEST DISTANCE FROM THE TANK FOR THE WELL? As specified in the Schedule of Items, 400 feet. Please assume the well location just to the side of the draw as you approach the tank, in the slight flattened area just downhill of the tank.

h WHAT IS THE TOTAL DEPTH OF WELL AT ARCADIA? 200 feet.

i CAN CONSTRUCTION WATER BE DRAWN FROM THE LAKE? Yes, a limited supply of construction water can be drawn from the lake.

j THE RIGGS WELL OPERATIONS SHED LOOKS LIKE IT IS IN A LOW SPOT – SHOULD WE ASSUME AGGREGATE BASE IS NEEDED? Yes, please assume an aggregate pad 20’ x 20’x 2’ high will need to be prepared before the well shed is constructed.

7 QUESTIONS AND ANSWERS (continued) k HOW DO WE HANDLE THE PAVEMENT CUTS AT RIGGS FOR THE WATER LINE CROSSINGS? Please assumed that you will not have to do pavement patch – just stabilized lime‐treated aggregate based course for the trench across the road.

l DOES THE EXISTING RIGGS CHLORINATION SHED GET REMOVED AS A PART OF THIS CONTRACT? Yes.

m WILL THE COLUMBINE WATER LINE GET RE‐ROUTED TO THE EDGE OF THE ROAD? For the bid, please assume that the line will be replaced in its current location, cross‐ country and through the vegetation to the Columbine Administrative Site.
