Title
Resolution - Authorization of Funding in an Amount Not to Exceed $600,000.00 and Approval of Contracts, Including Design Services with Freese and Nichols, Inc. and Surveying Services with Brittain & Crawford, LLC, to Prepare Aerial Sanitary Sewer Repairs 2019 for Public Bidding and Construction (Utility Bond Fund)
Requested Action
Consider the authorization of funding and approval of contracts.
Recommendation
The authorization of funding in an amount not to exceed $600,000.00 and approval of contracts, including design services with Freese and Nichols, Inc. and surveying services with Brittain & Crawford to prepare Aerial Sanitary Sewer Repairs 2019 for construction.
Description/History
The project consists of five individual sewer line repairs at various creek crossing locations as described below:
• Area 1 - Walnut Creek at US287: Replace existing 8” PVC line that spans Walnut Creek within a steel casing.
• Area 2 - Walnut Creek Trib 2 at Hobby Lobby: Convert an existing exposed 12” PVC sewer line crossing to an aerial crossing with piers.
• Area 3 - Walnut Creek at Fox Hollow Dr.: Stabilize the adjacent to the existing 42” RCP aerial sewer crossing streambanks to resist future potential damage to the sewer.
• Area 4 - Hogpen Branch at Cains Ln.: Realign existing 12” PVC sewer main and 8” PVC sewer lateral in this vicinity further away from the creek. An existing parallel sewer configuration will be combined into a single sewer configuration within the project footprint.
• Area 5 - Hogpen Branch at Brookfield Ln.: Combination of sewer relocation and bank stabilization to protect the existing 27in” PVC sewer line that is currently exposed in the bank of Hogpen Branch behind Brookfield Ln.
The requested funds are for design services with Freese and Nichols, Inc. in the amount of $450,000.00, an additional 10% design fee for potential design scope changes, survey services with Brittain & Crawford in the amount of $66,400.00, an additional 10% survey fee for potential survey scope changes, easement acquisition and other miscellaneous services, all to be accomplished within a budget of $600,000.00.
Justification
The proposed repair locations have experienced significant erosion causing the sanitary sewer lines to be exposed making them susceptible to possible significant damage. The proposed improvements will keep these sanitary sewer locations protected from future potential damage.
