Bowersox, F�ce�utive Direc INITIATID BY: A]an D. Archibald, Director of Public Services/City �gineer� J. Bradley Kutzner, Senior Civil F�gineer DATE: Novanber 25, 1986 SUBJF]CT: Contract Change Orders 21, 25, 26, 27 and 28 - Midland Road Widening - Hayward Enterprises BF�RQi(XIL�ID This project has gone through a series of construction difficulties. Recently more st�nnbling blocks have been encountered which will delay the projects ccmpletion beyond its target date of Decenber 15, 1986. The estimate3 cac�le- tion date has naa been revised to the end of January. Attachment 1 shows a s�ry of the problsns e�countered during construction. Many have required changes to the contract. Four major itans have crontribute3 to the delays. They are: 1) poor soil conditions along Rattlesnake Creek; 2) utility cc�qx�nies not performing in a timely manner; 3) Rattlesnake Crcek bridge not built to plans and spe�ifications; and 4) poor design/construction engineering. Poor soil problans were by far the most costly in both time and money, affecting four of the problan areas listed in Attackment 1 and account for about nine weeks of the delay. ACTION: NOV251986 ITEM �TJ=- ��C�/�rT Agenda Report - Contract Change Orders Nwenber 25, 1986 Page 2 The utility relocation issue, while not quantifiable in dollars and cents, added considerably to the total time of the job. Overall, the utility canpanies failure to meet their own goals for co�letion, and their lack of response to problans encountered during the cronstruction, m3de the project very difficult to sche3ule for consistent, efficient flaa of werk. Their efforts affected four of the problan areas listed and accounted for approximately five wee�ss of delay to the project. In all fairness to SDG&E, they wzre by far the most responsive (especially after the City Council spake with Mr, Keith Hutchinqs, the District Representative) . Pacific Bell and C�c Cable have been aware of the problens for weeks but have not yet resolved all of the problans to our satisfaction. Recently the contractor uncovered significant problens regarding the construc- tion quality of the Rattlesnake Creek bridge. It appears that this bridge Fras not built per specifications and will need a considerable amount of work to stabilize it. Unfortunately the contractor that built the bridge is naa out of business so the City can not reqaire the contractor to reimubrse the City for the repairs to the bridge. These problens have affected three of the areas listed on the attached list and will cause approximately six weeks of delay to the project and sane very costly change arders. Poor design or construction engineesing also played a gart in tw�o of the problan ar�s listed on the attache3 list and caused four weeks delay. Discussions on this m3tter are continuing with the engineering consultant. As a result of these problans, the follaaing additional change orders must be approved. The most critical one, change order #21, will require the construc- tion of a retaining wall approximately 180 feet long south of the Midland Road bridge. This solution, costing $18,830, was the least costly of three design alternatives examined by staff. It must be ca�leted after the concrete channel is poured and cured and before the road improvanents can be installed, it will dictate the schedule for the renainder of the project. Change order $25 provides for the installation of an additional 28 feet of dual 72" RCP stoxm drain, thereby allaaing a large portion of the western bridge abuttment wall to be buried and permanestly stabilized. It we�uld also reduce the length of channel construction accordingly. The net cast of this change order is $22,768.32. Change order #26 would authorize the purchase of 1500 L.F, of wood-grained, split rail-appearing, concrete fencing material in place of the tubular handrail originally specified in the crontract. The net effect of this change would be $3,172.95. Staff has estimated the installation costs at $5/L.F. for an addi- tional cost of $7,500 which will result in a future change order. NOV251986 ITEM C� FF - (��{�F / Agenda Report - Ca�tract Change Orders Novanber 25, 1986 Page 3 Change order #27, the shi£ting of six street lights to the v�st side of the road to avoid conflicts caith existing overhead pawer lines, amounts to $7,481.11. Change order #28 will provide small retaining walls in front of three properties in the north part of the project. Staff feels that these improvanents will significantly reduce the impact of the grading on these lots, at minimal cost, and improve the project appearance. This change will, based upon contract unit price, be acca�lished for $7,000. FII�IDIl4G6 Chanqe arders 21, 25, 26, 27 and 28 are necessary to the ti.mely and efficient ccx��letion of the project. I�ICN It is recamiended that the Redevelopnent Agency approve change arder #Z1, (Attach¢nent 2) for $18,830; #25 (Attacknnent 3) for $22,768.32; #26 (Attachment 4) for $3,172.95; #27 (Attachment 5) for $7,481.11; and #2$ (Attachment 6) for $7,000.00.
