Determination of the Bid Imbalance The J. W. Riley and Son bid was determined imbalanced based on the following: Contract specifications Section 2.10 D. on page 00210-6 and 00210-7 of the General Conditions (attached), "Proposals in which prices are obviously unbalanced may be rejected by the City Council." Staff determined that it is not in the City's best interest to accept this bid due to the unbalanced preparation of this bid. There are extremely Iow prices for four bid items which represent supplemental work on the project combined with the excessively high prices of the four bid items which represent the main work on this project. Examples of the imbalance: (1) Bid Item 8 Construct wheel chair ramps $4.25 per SF Historically, including the 1999-2000 J.W. Riley bid, the cost to construct wheel chair ramps is more expensive than constructing sidewalk or driveway, due to the finishing time necessary to shape, score, and finish the ramp details. The $4.25 per square foot price in the current J. W. Riley bid is $1.25 per square foot lower than the 1999-2000 J.W. Riley bid, yet his sidewalk construction increased $1.30 per SF and driveway construction increased $1.75 per SF. Wheel chair ramps are more expensive to shape, finish, and score than sidewalks. (2) Bid Item 11 Install Irrigation system $2.00 per LF To perform this task, excavation, pipe and sprinkler head purchase, installation matching the existing irrigation system, head tuning, testing, and backfill are required. This cannot be accomplished at the bid price of $2.00 per lineal foot, which for a typical twenty foot long location would amount to $40.00. The costs of materials and la: or would exceed $40. This bid price is $1.00 per LF lower than his 1999-2000 bid price of $3.00 per LF, which staff found was too Iow to perform the work correctly at that time. (3) Bid Item 12 Install tree grates $25.00 Each This bid item requires the grading, forming, setting of tree grate frame to proper grade, pouring and finishing of concrete, stripping, clean-up, and backfill of the location, and placement of a City-supplied tree grate. It will cost more than the $25 bid price in labor needed to perform these activities plus the materials necessary to perform this task. (4) Bid Item 7 Remove walkway $2.00 per SF This bid item requires the sawcutting, excavation, removal, and disposal of walkway material in the planting strip, and replacing top soil to grade, and installing appropriate twenty-four inch stepping stones. A typical location would be 24 SF. It will cost more than the $48 bid price to perform this task. (5) On the contrary to these Iow prices, the bid prices for sidewalk removal and construction and driveway removal and construction are the highest staff has received in bids for the past three years. These four bid items typically comprise over half the contract, and historically have been increased by as much as 25% through change orders as staff receives requests for more cost shared repairs.
