City of Fontana 8353 Sierra Avenue Fontana CA 92335-3528 RE: Slover Avenue Sewer Improvements from Poplar Avenue to Sierra Avenue BID No. SB-67-01 Dear Mr. Gdula, We have been delayed by the long time it has taken to remove the many telephone and electrical poles that were along Slover Avenue. The poles delayed the project so long that the construction method envisioned prior to bidding was completely abandoned. The poles also caused extra expenses working around them with traffic control. Construction had to progress or wait until July 3 when the last pole was removed. Because of the delay, the poles did generate a credit back to the City in that we never did lay down the asphalt detour that was originally planned. The City also generated another credit when the City deleted the slurry that was called out for under the existing asphalt. These credits are an estimated $104,000 or 2,000 tons at the bid price of $52.00/ton (2,330 tons less than what we expect to use, 330 tons) and $82,900 for the slurry not used from the estimate. However, I am asking that we be paid for the slurry that we did use on the project supporting crossing lines (92 yards at $63.34/yard). This yardage was not separated from the original estimated slurry on the job. The delay in removing the poles forced the construction into the traffic lanes of Slover Avenue. Because of this we were forced to construct the southern laterals and 8" lines using flagmen to a much greater extent than what we had originally bid. This also caused the southern lines to be constructed in two phases of work in order to keep traffic moving through the area. This complicated the construction and cost an additional 47 crew days to construct these lines. Therefore, I am also requesting a change order for $140,843.49 for the extra crew days caused by the delay of the poles and change in construction method. (47 days at $2,999.67 per 5-man crew day, see extra work report attached). I am also requesting the costs for the additional use of 190 flagman days or $69,488.70. (190 days at $365.73/flagman/day extra work report attached). I have enclosed a number of spreadsheets with the details of the above. If you have any questions please contact me. Sincerely, Lester A.

The Target Dates represent the original schedule. You can see how the impact of the telephone poles have delayed the project and forced a different method of construction using flagmen on all parts of the project. With this schedule I am requesting additional time to extend the contract to August 16, 2002. The plan is to continue to keep two crews on the job to make up some time to complete the job quickly. I will follow up this letter with correspondence to request additional expenses for crew extended time to construct the project with traffic and with additional flagmen. Sincerely, Lester A.

City of Fontana 8353 Sierra Avenue Fontana CA 92335-3528 RE: Stover Avenue Sewer Improvements from Poplar Avenue to Sierra Avenue BID No. SB-67-0 1 Dear Mr. Gdula, We have a problem with the traffic control on the. very east end of the project. The survey has the pipeline 19' off the center island curb. The traffic control calls for K-rail in place with 12' allowed for a traffic lane, The problem comes in that the ditch is running 10'wide and the track hoe needs 12' from centerline to swing. With the ditch at 5' into the 19', 1' allowed from ditch to K-rail, and 2,5' for K-rail that leaves only 10.5' for the traffic lane and 3.5' short for the machine to swing. There are two solutions I would like to suggest. The first is to close the westbound lanes for two weeks while we construct the pipeline in the current alignment. Allowing access for the local homes only. The second option is to add a manhole at station 171+25 +/- and bring the pipeline alignment to 6.5'-7' off of the center island's north curb and continue pipelining with flagmen. This would allow a westbound traffic lane on the north side of the street without the use of K-rail during the day. For of hours we can K-rail or plate the ditch for safety. Our preference is to close the westbound lanes and complete the project with the maximum amount of safety. Please contact me right away so there is not an interruption in the work Sincerely, Lester A. Davies Faxed Only JUN-06-2002 16'• .5�5 . I � f]�RT � ;.

Avenue Sewer Improvements from Poplar Avenue to Sierra Avenue BID No, SB-67-01 Dear Mr. Gdula, We are looking at a delay with the work in Stover Avenue due to the telephone poles that are on both sides of the street. The north sets of poles are in the alignment of the mainline sewer and will cause mainline work to stop soon. The poles on the south side of Stover Avenue have prevented us from doing the pavement required on the job and still delays that work today. These conditions have already caused us to piece meal the work on the laterals. The poles have delayed the schedule and now threaten to stop the whole project. Please do what you can to keep us moving, If there is anything 1 can assist you with please let me know, I will be happy to help. Sincerely, Lester A. Davies 14xcs' 4-4-vz 5/'5j' TOTAL P.01 ALB.T W.

My problem is that the raiser pipe is being laid on a slope out of the wye and not straight up to grade. This has a tendency to break the wye at the bell or the spigot going into it. We are installing them as directed, however these may fail at a later date and we do not support this installation. Sincerely, Lester A.

As you can see the schedule is fairly tight and may have to be altered to complete the work on time. I will keep you informed, as those events become clear. To answer your request about arrow board rental, as long as I am able to use our arrow boards the rates are $45.00/day, $180.00/week, and $540.00/month. If we had to use outside boards we would have to add 20% to these rates. This would be for either the solar boards or the diesel boards. Sincerely, Lester A. Davies P.O.

Co•/Dept. Co. Phone a Phone # Fax # ISco �Co(o i C.J Fax # 12411 Don, In response to the fax's received today regarding the sewer construction pro,jeet in Slaver Ave. 1 am suggesting the following. 1. Capri Mobile Home Park: the lateral al station 177+28 per the approved plan has an invert elevation of 1076.95. In order to accommodate the design of Boyle Engineering tier the mobile home park, they are requesting that this be changed to an elevation oif 1076.10 at this point. The simplest solution to this is to lay the wye flat and extend the lateral to the property line at 1% in lieu of 2%. This would eliminate any changes to the main line sewer and would give an elevation of 1076.14 at this location. 2. Sand Slurry Backfill: A.W. Davies is requesting that they be allowed to use sand slurry baciclill at water crossings in lieu of pipe supports. I do not believe that this is an acceptable alternative and therefore would not support this change request. L.D.

City of Fontana 8353 Sierra Avenue Fontana CA 92335-3528 RE: Slover Avenue Sewer Improvements from Poplar Avenue to Sierra Avenue BID No, SB-67-01 Dear Mr. Gdula, We have several places where we cross existing utility lines on the project. Some of these call for a concrete beam or a cement slurry backfill to springline to prevent any settlement of that utility. A few years ago we worked for the Mojave Water Agency in the City of Barstow, The City has many existing waterlines using asbestos -cement pipe. The Mojave Water Agency has a requirement to backfill under these lines with a sand slurry mix. This is a sand and water mix only placed by a cement truck with mixer. They do not want any cement in the mix because it becomes too rigid and a solid mass. Since that project we have used this mix many times and most recently with the City of Upland. We have been very successful with these crossings and have never broken an asbestos -cement pipeline yet, We have crossed 4" up to 12" size waterlines with success. And as you may know, when you cross an asbestos -cement pipeline the line usually breaks a week or two after the backfill occurs when everyone thinks we are safe. Therefore, I would like to use this mix and placement method for the lines on the project were slurry or a beam is required. Sincerely, Lester A. Davies ALBRetT W. DAVIA , INC.

We propose to close the eastbound lane of traffic and install the lateral from the centerline of street to the southern terminus. We will control traffic flow east and west with flag people during construction hours and return the lane at the end of each day or sooner as practical. Then when the detour is built (the new pavement on the south side) we will detour traffic to the south side of the street (again with flag people) and construct the northern half of the lateral, again returning the lane at the end of the day or sooner. We will be using the CalTrans Manual for the details of the lane closure and request that we are allow to restrict the lane width to 3 meters (9.83 feet) only when necessary as CalTrans Manual allows. If this is agreeable with the powers to be please let me know as we hope to start soon. Sincerely, Lester • . i avies Fax'd Only TOTAL P.01 ALBAT W. DAVIJ , INC.

City of Fontana 8353 Sierra Avenue Fontana CA 92335-3528 RE: Slover Avenue Sewer Improvements from Poplar Avenue to Sierra Avenue BID No. SB-67-01 Dear Mr. Gdula, We have been delayed in starting the Slover Avenue Project due to a heavy rainfall that occurred on January 26/27, 2002. The storm wiped out the intersection of Beryl Avenue and Highland Avenue in Rancho Cucamonga including the sewer, water, electrical, and the storm drain we were installing at the time. The storm filled our 120" storm drainpipe with over 600 cubic yards of dirt and debris. Unfortunately our clean up and restoration efforts have delayed other work we have. We are now completing the work in Beryl Avenue and should be able to start work Monday or Tuesday March 4th or 5th on Slover. I apologize for the delay of your project and at the same time appreciate the cooperation of the City with our lost. Sincerely, Lester A. Davies P.O.
