PROPOSAL TO PROVIDE INSPECTION SERVICES PROJECT 1112100-151 FAIRVIEW ROAD SEWER Dear Board of Directors: The following proposal is for providing the necessary construction administration, engineering, construction surveying and inspection services during the construction phase of the project. Attached are copies of the project reports as described in the Capital Improvement Program as well as the Boyle Engineering independent report. It is proposed to provide the following services, as needed, during the construction phase of the project, not to exceed$10,400 Engineering $ 63 00/hr Inspection 42.00/hr Surveying(2 man crew) 155 00/hr Surveying (3 man crew) 185 00/hr Sincerely eitpil., Robin B Hamers 3 Printed on Recycled Pape PROJECT 1112100-151 RECONSTRUCTING VARIOUS SEWER LINES The project is similar to past projects #122 126 132 140 and 145 which includes rehabilitation and maintenance of the existing gravity sewer line system on an as-needed basis The results of the original four large televising projects plus the small yearly projects have disclosed existing problems in the main lines such as sags cracked pipe collapsed pipe offset joints and root intrusion The project sets up a priority list of the problem areas and repairs the lines on this basis The project is a yearly project and part of an ongoing maintenance program The only problem type mentioned above which is not repaired by this project is root intrusion which is handled through root cutting by the District Throughout the past projects of this type the District has repaired the problem areas using two different methods Two of the projects were designed using standard remove and replace construction where the contractor excavates down to the line, makes the repair and then backfills and repaves One of the projects was completed using Link-Pipe where stainless steel sleeves were inserted into the line adjusted to the right location using a camera, and then expanded to permanently seal itself Link-Pipe is generally an easier and more economical repair method however it has some limitations in its application The decision to use Link-Pipe or remove and replace construction will be made during the design phase when the scope of each repair is more fully investigated Previous costs for excavation and reconstruction have been approximately $650/foot since the footage is only between two and six feet This would allow approximately 35 locations to be included in the project Link-Pipe costs have averaged $3 500 per location or approximately $700 per foot - 7 - An estimate of the project costs is as follows Design $ 9 600 Construction 115 000 Inspection 10 400 Reserve or Contingency 15 000 TOTAL $ 150, 000 - 8 - Soule Engineering Corporation CC_ I.J: s _ r 1 Co it F'O .0_ FAX 7 / 7' N't port CA _ '020 _ •E1 Lit:1'.rri :•iI1^4`ir^>_ -.- t-r- ._a:.iEPnr;ir_ . a'. .`,:raiSarc ='Y°^'Fnrr"=cc:" TRRfISPORTRTJOrl SERVICES Mr Robin Robin B Hamers.
