WHY THIS MATTER IS BEFORE THE BOARD Board action is required for expenditures in excess of $15,000. 2. HISTORY The Water Department anticipates restarting its annual pipeline replacement program, beginning with award of the District Pipeline Replacement - 2013 project. The District had a full Light Detection and Ranging (LIDAR) survey and aerial photography performed in 2007. Updated aerial photography was performed in 2011. This information is the basis of the District's current base mapping and is quite accurate. The location of existing ground level structures such as utility poles and manholes can be determined from the LIDAR survey and current photography. However, underground utilities such as gas pipes, sewer pipes, water pipes and storm drainage was not developed as part of the LIDAR survey. The District has undertaken a number of pipeline replacement projects within the Tahoe Donner subdivision, and the Water Department has a level of confidence in the as-buill drawings for that area. The Water Department has been able to avoid the expense of utility surveying in Tahoe Donner because of these reasonably accurate as -built drawings. However, relatively few projects have been undertaken in other parts of Truckee and as - built drawings do not exist for some of the subdivisions. Consequently, it is necessary to have utilities in these areas surveyed in order for the design of the replacement pipelines to proceed. 3. NEW INFORMATION In addition to ongoing work in Tahoe Donner, pipeline replacement work is anticipated in the following areas over the next few years: 0 Biltz Tract • Gateway Park • Meadow Lake Park • Olympic Heights • Prosser Lakeview - Rainbow & Whitetail (utility survey was performed in 2008) In early March, the District issued an RFP for surveying. The deadline for submission of proposals was March 20, 2013. Three tasks were included in the RFP: 1. Location of existing property corner monuments in the areas where pipeline construction will occur during the Summer of 2013 2. Verification of property corner monuments and staking of the easterly property line at the Donner View Tank site 3. Surveying of utility location field markings at various locations throughout Truckee Six proposals were received in response to the RFP from: • Andregg Geomatics - Auburn, CA (Andregg also maintains an office in Truckee) • Auerbach Engineering - Tahoe City, CA • KB Foster - Carnelian Bay, CA • MAPCA Surveys - Reno, NV • Sage Land Surveying - Truckee, CA • Wood Rogers - Reno, NV The proposals were reviewed by a committee of Electric Department and Water Department staff. The committee determined the following: • All of the firms are capable of performing the work described in the RFP • All of the firms employ appropriately licensed individuals • Five of the six firms have performed work for the District in the past. Wood Rodgers is the only firm that has not • Two of the firms (Andregg Geomatics and Sage Land Surveying) qualify for the local procurement preference described in Section 3.08.005 of the District code Considering that there is not a significant technical difference between the firms, the cost proposals were then reviewed. Andregg and MAPCA submitted the lowest cost proposals, with all of the remaining firms at least 10 percent higher. The total cost from MAPCA was $33,000. The total cost from Andregg was $34,950. When considering the local procurement preference given to Andregg, the cost differential between the two firms for evaluation purposes is about $200, with Andregg still slightly higher. It is recommended that the work be awarded to MAPCA. 4. FISCAL IMPACT The cost proposal from MAPCA is $33,000. It is also recommended that a 10 percent change order allowance be established for this contract. Fe:7xd91IVAILT, 14ki1I7_AIIORII Award a contract for surveying services to MAPCA in the amount of $33,000 plus a 10 percent change order allowance for a total not exceed $36,300. Michael D.
