Questions Answers

1 We can’t find a cross section for the culvert at 3769+00. Also, the plans call for a culvert 3775+10 and the cross sections call for a culvert at 3775+90 that is not shown on the plans. We are still looking through them all but wanted to point out what we found so far.

Culvert at 3769+00

The culvert at 3769+00 was identified for replacement late in design, there is no survey or mapping at this location, so there is no cross section. The contractor will need to prepare plots per 15215-3000 Survey and Staking, Drainage Structure and submit to the CO for approval.

Culvert at 3775+10

The culvert is located at 3775+10. The cross-section label is incorrect and has now been fixed.

2 Is item 62303-1000 is lump sum. Is that correct?

The Pay Item 62303-1000 Special Labor, Hired Technical Services has been revised to be by Hour for Schedules A, B, and C.

3 It looks like sheet A-4 was a cut and paste from Cottonwood West.

Probably not a big deal but wanted to point it out.

The points shown are correct. However, survey points at the summit were inadvertently left off. Sheet A4 has been revised.

4 Line Item C1040 – Concrete (Collar, MSE Repair) –The Item

Quantity is 3 CY. The Plan details (sheet T-6) indicate a concrete quantity for each size Collar. For example a 24” would be .595 CY.

Is this the quantity that will be used for measurement and payment?

There is a significant amount of work and cost associated with the

MSE Wall repair that is to be included in the CY price. The other

MSE wall repair locations are to be measured and paid as EACH.

Because of all the subsidiary work could this item be changed for CY to EACH?

All work related to removing and replacing the section of MSE wall for the culvert installation is included in the pay item 60101-0000 Concrete

(Collar, MSE Repair), which will be paid for as CUYD of concrete. The unit will remain CUYD.
