Rather than re-explain the project scope enclosed as backup are the project description as prepared for the Capital Improvement Program as well as Boyle s report Therefore it is proposed to complete the design phase of subject project including preparing construction plans and specifications for bidding at the following hourly rates not to exceed $10 000 Engineer $ 59 00/hr Draftsman 47 00/hr 3 man Survey Crew 170 00/hr 2 man Survey Crew 150 00/hr Sincerely .ilw;r Robin B Hamers RBH/jp/proposal cms Encl t: Printed on Recycled Paper Mr Robin Hamers July 2, 1993 Page 2 p y L- ?apo i2 I Project 1112100-135 Elden Pumping Station Force Main Project description adequately described the project to be undertaken. Use of recap from Phase I was very beneficial. This allows the layperson to understand the concept and need of the entire project. Design and construction engineering services are estimated at 8.5 percent of estimated construction cost. This appears to be slightly low 10 to 15 percent is consistent with acceptable estimating however the percentage is within the amount used for Phase I. Contingency funds of 40 percent for Phase I are to be carried over to Phase II and this should be adequate. It is suggested that estimated size and length of pipe to be constructed be included as part of the project description. Recognizing the project will involve/require Fairgrounds/City and District cooperation as well as coordination, it still appears that adequate funds are being programmed assuming timely design and construction of the project. Project 1112100-136 Access Road along Newport Beach Golf Course Project description adequately indicates what is to be accomplished. Contingency costs. 20 percent of construction. appear to be in keeping with acceptable estimating practices however design and inspection. 42 percent of construction appears high. This may be appropriate if there is a lot of miscellaneous plans. derails and surveying work needed for isolated locations as well as an abnormal amount of coordination with the golf course. Project ] 112100-1.)7 Televising Sewer Lines As discussed for the 1992 93 CIP program and with District staff this is a service type project not construction. Therefore, normal design. construction and inspection percentages do not apply However it is suggested that other terms be used rather than 'Design and Construction. The estimate televising costs represents approximatek 14.000 I.f of pipe to be televised at 80.35/1.f based on discussions with District staff Because of the nature of the project and that District staff is needed at all times for cleaning ahead of the camera, coordination, and supervision of the work. the District Engineer costs will be higher percentage wise. versus a design project. It is suggested that for future similar projects the first three items above be included in the project description to more clearly define the scope of work. Project 1132100-138 Reimbursement for Sewer Work by Others Purchase Manholes Project description adequately describes what is programmed and why the District needs to appropriate funds for this function. sITg4, � ?` DISTRICT COSTA MESA a` {�y �wzr� r DIRECTORS Costa Mesa Recycles y' .j. ♦w lames Wahner i • rO001tkiE�`9 lames Ferryman - Nate Reade Arthur Perry Mike Scheafer Project 1112100-135 Reconstructing Force pain for Elden Pumping Station (Phase II) The project as more fully described in the 1992-93 Capital Improvement Project report (CMSD 1112100-130) entails replacing the old force main with a stronger more reliable material that will not easily rupture The force main is the District s largest and carries the heaviest flows Phase I of the project was included in the 1992-93 budget since the project size warranted dividing the construction into two phases Furthermore the 1992-93 budget was approved with a deletion of $150 000 from Phase I of the project as shown in the 1992-93 report The deletion left sufficient money to cover Phase I construction but necessitates full funding for Phase II It was originally anticipated that the design appropriation in Phase I would include preparation of construction plans for Phase I and II However the following events have necessitated an additional design appropriation for Phase II 1 Phase I construction was itself broken into two portions The first portion is a segment of force main to be installed under Newport Blvd southbound under a change order to the City s contractor for the Newport Blvd rehabilitation project The District could only meet the City s schedule by installing this portion separate from the remainder of Phase I This required preparation of a separate set of plans and separate processing through CALTRANS and the City of Costa Mesa 2 The alignment for the remainder of Phase I was obtained after extensive negotiations between the City of Costa Mesa CALTRANS and the District CALTRANS would only allow the District to install the force main in the desired location if the City agreed to assume ownership of the land which is the landscape strip on the east side of Newport Blvd southbound from Mesa Drive to Fair Drive between the back of curb and the fence As a condition of accepting the land the City subsequently required the District to enter into a landscape maintenance agreement where the District will pay the City to maintain the strip The agreement also requires the District to prepare an easement map and description for use of the land The remainder of Phase I will be put out to bid in early June with bid opening in early July - 5 - P.O.
