Question 18: Spec 15072, 2.01, B.3 calls for “square headed carbon steel machine bolts”. Please confirm that square headed bolts will be required. There is a significant cost difference between Square Head Bolts and Standard Hex Head Bolts.

Response 18: Bolts may be either square or hex headed. Section 15072 has been revised in Addendum 2

to include this change. Question 19: On the well that is to be pulled and treated, if the existing pumping equipment is bad and

has to be replaced and this increases cost above the $75,000 allowance, how would we handle this? Change order?

For new well testing and development, we will provide hose to get water 300’ from the

well. Can the water then run out on the ground? Once the existing well is treated, can the debris on the bottom of the well be cleaned out

with a bailing bucket instead of airlifting the debris out? Can drill cuttings and drill fluids be disposed of onsite?

Response 19: If the Well 8A pump is to be replaced, a change order will be required. Drilling fluid may be disposed of by pumping to the land surface at the approved location

where water will be discharged during development and test pumping. Specification Section 02676 has been modified to include this statement.

Per specification section 02676, paragraph 1.05C.5, removal of debris from the bottom of

the well shall be carried out by reverse air-lift pumping or sand pumping.
