Box 640 Bozeman, MT 59771 RE: Bozeman Water Repair and Renovation Dear Rick, I I 'dMM& Wft WINVEN&L 141(111 E n C1 I n cp4a r I r Cj Johnston Excavating submitted letters of additional work on September 2, and September 28, 1996, The following is our recommendations regarding these requests: Item #1 - Recommend Approval. We are in agreement with the quantity and recommend payment. Payment covered Linder Change Order No. 1. Item #2 - Recommend Approval. This item is for the repair of an existing sewer main which was crossed at the intersection of Wallace and Cottonwood. The leak was not caused by the contractor, but was pre-existing. We are in agreement with time and materials used, and recommend payment. Item 93 - Recommend Denial. This item is for additional fitting required for the water main interconnection at the intersection of Wallace and Cottonwood. The contractor was unable to ready-rod the 90' ell to both the valve and tee without the addition of Mega followers. We recommend against payment for this item as an extra. The contractor and his material supplier should have foreseen this problem and had materials on-hand to complete the assembly, Item #4 - Recommend Approval, This item was for the installation of a fire hydrant riser. The riser was required because of greater main depth to pass beneath an existing sewer service. We recommend payment for this item. October 9, 1996 Mr. Rick Ilixson Page 2 Item #5 - Recommend Approval. This item was for the replacement of an existing 6" gate valve. The valve was found to be "bad" at testing of the main. The valve had to be excavated and installed in line. We recommend payment for this item, Items #6 & #7 - Recommend Approval. These items are for replacement of existing curb stops found to be "bad". Recommend payment for this item. Item 98 - Recommend Partial Approval. This item is for the insulation of shallow main. In making connection to existing main at intersection of Church & Peach Streets, it was found that the existing main had inadequate cover, requiring insulation over the new main until proper cover Could be provided, We recommend payment for the 84 LF of insulation. Tile other items are covered by the base bid and Change Order No. 1. Item #9 - Recommend Approval. This item is for additional crew and equipment time at the Garfield and 4th Street connection, The existing pipe and valve configuration was substantially different than shown on plans. We recommend payment for this item. Item #10 - Recommend Denial. This item is for the repair of a sewer service that was 2' higher than shown on the plans. We recommend against payment for this item.. Our recommendation is based on the fact that the service was pre- marked correctly and the contractor should have been more prudent in excavating in the vicinity of the service. Item 41 - Recommend P art i al Approval. Existing service at Station 7 was I" verses typical 3/4" service, Recommend partial payment for labor costs. The 376.09 is not justified because other work could continue, October 9, 1996 Mr. Rick flixson Page 3 Item #12 - Recommend � pproval.
