COSTA MESA, CA 92527 CIVIL ENGINEERS • PLANNERS • SURVEYORS (714) 545-1192 January 30, 1998 FAX (714) 545 6516 Board of Directors Costa Mesa Sanitary District P 0 Box 1200 Costa Mesa CA 92628 RE PROPOSAL TO BEGIN PROJECT PROJECT 1112100-152 TELEVISING SEWER LINES Dear Board of Directors Previously four large phases of televising projects were completed over a four year period covering the majority of the District' s sewer mains and the results of the televising have become the foundation for determining the schedule for maintenance and rehabilitation of the sewer system After the four large projects the fourth of a series of small yearly projects was authorized and is nearing completion This project as shown in the 1996-97 Capital Improvement Program is the fifth in the series of small yearly projects and will achieve the following results 1 By limiting the televising to less than $10 000 per year the project does not have to be bid The District can select its own contractor which will be the contractor who was the low bidder and completed the four large televising projects This will provide continuity in record keeping and efficiency in completing the work since the contractor is familiar with the system 2 The District receives frequent calls from homeowners who believe tree roots in the District' s main line are causing stoppages in their laterals By having the televising contractor working on a regular basis throughout the District the contractor can easily include areas where there is a potential dispute 3 Certain areas need to be re-televised to check the structural condition of the pipe and to determine the effectiveness of the root cutting and foaming 4 There are some areas that have not yet been televised and these areas will be a part of the proposed small yearly televising projects ® Printed on Recycled Paper. Board of Directors January 30 1998 Page 2 5 The main focus of this project will be to compare the current condition of the lines with that of the 1989 televising project and include the results in an Engineer' s Report This will help determine whether significant portions of the system need to be re-televised The project appropriation as shown in the 1996-97 Capital Improvement Program is as follows Design $ 2 , 750 Televising Cost 6, 000 Inspection 3 , 750 Engineer' s Report 2, 500 Reserve 2 000 TOTAL $ 17 , 000 It is recommended the Board authorize the televising to be completed for less than $6 000 and the Manager/District Engineer to complete the design and inspection and Engineer' s Report at the following hourly rates not to exceed $2 750 and $3 750, and $2 500 respectively Engineer $63 00/hr Inspection $42 00/hr Sincerely Robin B Hamers RBH/jp/proposal cms x`196-11 CAP 4wosr PROJECT 1112100-152 TELEVISING SEWER LINES The project is the continuation of the ongoing yearly "pick-up" projects where it is proposed to begin rechecking areas that were originally televised in 1989 under the first phase of the District's televising program Certain areas of the first phase where problems were encountered such as roots, multiple cracks or longitudinal cracks will be re-televised to compare the 1989 condition versus the 1997 condition This will assist in determining whether significant portions of the one million feet of District main line previously televised will need to be re- televised Upon completion of the televising, an Engineer ' s Report will be prepared that outlines the results of the comparison and determines the need for future similar projects The areas to be televised are included in the 1989 televising area which is shown on the attached map Recently the District adopted Ordinance No 26 which allows, in accordance with State law, sewer projects up to $10 000 to be completed without going to bid The televising portion of this project is $6 000 and this will allow continued use of the contractor who has completed the District ' s previous televising projects The design portion of the project encompasses preparing maps and schedules for the contractor Preparing the maps includes reviewing previous televising projects to determine areas where re-televising is appropriate The previously used area and manhole designation system will be reused Inspection consists of monitoring the District' s cleaning forces schedule since the District must clean the lines immediately prior to televising, as well as being present during the televising operation The televising cost is estimated at 12 , 200 feet of pipe at $0 49 per foot - 9 - An estimate of the project costs is as follows Design $ 2 750 Televising Cost 6, 000 Inspection 3 ,750 Engineer's Report 2 500 Reserve or Contingency 2 , 000 TOTAL $17 000 - 10 - 0) D TT a Z C \,. on, .1, I -1)- '.4 'of\ f ` 0----12-. r M� - i . , ""'`� F I ' •` :41 H py a \ 'T,r {?. rag; / /_f /7 i`�__ .'fir cI c4 I "- n \ ,- .

S I b I b co Toy,t Rfft07- Independent Review Costa Mesa Sanitary District Capital Improvement Program Fiscal Year 1996-97 + Project 1112100-149/SINKING FUND This is the second year that funds have been set aside for future replacement or reconstruction of sewer lines as they reach life expectancy Setting aside funds for future use now will benefit from compounding over time. o Project 1112100-150/PUMP STATION ALARM SYSTEM UPDATE The Districts existing radio-alarm system is reaching its life expectance Parts may be obtainable for the radios but the alarm reporting system appears to be unsalvageable. The District Engineer has recommended that bids include replacing the radios as an alternative, which I support. The use of a radio-alarm system has great value and benefit. The main saving has been in reduced response time. auto shut down of pumps when a problem has occurred, and a reduction in overflows when there has been a failure. The construction cost appears reasonable as does the design and inspection fees. o Project 1112100-151/SEWER LINE RECONSTRUCTION \ arious Locations This .s the sixth allocation in a continuing program t0 yovide funding for maintenance of,e' -er 1-ne.s at \arious locations. Tins s a maim tenance program and priorities are established from the data ai,d analysis -eceit ed from -evious televising of the Distn_ts sewer lines Since -epairs are small in length the a\erase cost per toot will be higher when compared to major replacement projects The engineers estimate appears reasonable The design and inspection fees of S % and 9% respectit el' appea, to be „.thin acceptable standards. The 130/0 contingence estimate is reasonable. o Project 1112100-152/TELEVISING SEWER LINES This is part of an ongoing program to insure that the Districts facilities are functioning properh The District Engineer proposes to check lines that were televised approximateh eight \ears ago this will provide significant information in which to draw assumptions regarding other portions of the Districts facilities. The engineering fees are higher than normal projects but since this requires proper selection of locations to be televised coupled with reviewing the tapes and report preparation. the\ seem acceptable. The inclusion of the e icinity map was beneficial and appreciated e Project 11121100-153/ROOT INTRUSION STUD)' Sct',cr Laterals This is the first \-ear fo. .his program. It appears to be a ,oint effort between the District and the Citt to provide a public son ice as well as helping to identift potential problemslconflicts.
