PW77-060770500020 & PW77-060770500030 This office has reviewed your correspondence dated October 15,1996 on the proposed contract modification (PCM-022 ) concerning the three safety related items for the North Holly Water Treatment Plant which where requested by the plant. Item 1. Galvanized Steel Stairway at North Holly Raw Water No. 1 Valve Vault. The requested that a stairway be installed at the RW41 Valve Vault. Currently assess is limited to the unimproved road at the top of the levee making assess is difficult and dangerous during wet weather. The Stairway will allow assess from the a lower parking area. The Water Department agrees with your recommendation that the contractor price proposal of $8,138.88 for this item should be accepted as the cost provided is fair and reasonable. Item 2. Modify North Holly Raw Water 2 & 3 Post Chemical Application Vault Lid. Current assess is through a standard 24-inch manhole rim (and cover) using a ladder. This is to small to allow assess for personnel when using an airpack. The plant has requested that the vault lid be modified to install a larger aluminum (Bilco) hatch and to install a safety ladder in the vault. The Water Department agrees with your recommendation that the contractor price proposal of $5,375.89 for this item should be accepted as the cost provided is fair and reasonable. Item 3. Remove Portion above of North Holly Sedimentation Basin 41 Wall. The plant requested that a portion of the North Holly Sedimentation Basin 41 Wall be removed (above elevation 551.0) to allow visual inspection of the chemical storage area from the road. The Water Department agrees with your recommendation that the contractor price proposal of $2,714.32 for this item should be accepted as the cost provided is fair and reasonable. The Water Department understands that total cost of all three items is $16,229.06. Further, the Water Department understands that while this PCM does not include additional contract time, should it not be approved before December 6, 1996, additional costs (overhead costs) and additional contract time may be required.

This PCM consists of three safety, related items for the North Holly plant which have been requested by the plant staff. Item 1 provides new stairs at the North Holly Raw No. 1 valve vault.. Currently access is limited to the unimproved road on top of the levee which has traffic ability' problems during wet weather or up a steep grass slope from the lower parking area. Item 2 modifies the existing access manhole on top of the North Holly Raw 2&3 Post Chemical Application Vault to be an access hatth and ladder. Currently there is no ladder into the vault and the manhole is too small to enter easily when personnel are wearing an air pack. Item 3 lowers the east wall of the existing North Holly abandoned sedimentation basin by deleting the upper wall section. Removal of this wall improves plant visibility into the new chemical storage area. We have reviewed the price proposal and recommend the City authorize this additional work and issue a Change Order.The costs associated with these items are$ 8,138.88,$5,375.89, and$ 2,714.32;the total cost of all three items is S 16,229.06. Mr.David Townsend October 15,1996 Page 2 No additional Contract Time has been requested if approval is granted by the City by December 6,1996.Cajun has advised us that due to lead time on the Item 1 stairs and the Item 2 hatch and ladder that they will need additional Contract Time and overhead costs as these items will become critical path activities if approval is received after December 6th. We concur with Cajuns assessment of their schedule. Please advise if the Nater Department desires this PCM, or any portions of it, to be incorporated into a Change Order.
