Adopt Resolution No. '14 -301 approving increase in contract limit by $250,000 to
expenditures for Contract 31 66, Palomar Airport Road and El Camino Real Widenir
ITEM EXPLANATION:
On December 8, 1992, the City Council awarded a contract in the amount of $6,4
to West Coast General, J.V. Council also has authorized a construction continge
$1,047,369. The project is nearing completion and an increase in the contract limit a
is required to meet the final project costs. These cost increases are due primz
change order and bid item quant'ity increases in the area of Recycled Miscellaneou:
and earthwork.
Recycled Miscellaneous Base (RMB) is the reuse of existing pavement and roc1 material in the new roadbed. At the time of bid it was estimated that all of the e
pavement and one half of the existing rock base could be recycled. During consti
West Coast General Corporation, J.V. found it possible to recycle all of the material ii new roadbed. The contract allowed for this option; however, because the cost of !e base exceeds the combined costs for excavation and new base material, additiona
are required.
Maximum utilization of recycled material is consistent with Council policy and aH
somewhat more expensive, results in more efficient use of scarce material resourcl
reduces transport impacts on the community.
The second area of major cost impact is in the area of earthwork. To avoid PC
delays in construction due to gnatcatcher protection, a change order was approved
import of dirt into this project which was not otherwise available in a timely manne
quantity of dirt required to complete the work was in excess of the estimated amo
In addition to the imported earth, unsuitable soils material in the foundation i
roadway exceeded the amount expected under the original contract. These areas, as alluvial fill areas, required excavation and recompaction by the contractor. Inc
in alluvial removals are not uncommon. The work is not visible prior to constructic
the precise extent of removals cannot be known until the actual excavation proceed
increase due to this item of work exceeded original estimates and the precise amoi been a matter of dispute until recently.
During the course of this contract, an unusual number of time and material change
have been processed. The reason for this is the difficulty in deriving a scope of wo
to various unknowns in performing the work and the difficulty in negotiating fair pricc
the contractor. These types of change orders are for estimated amounts whicl
exceeded in some cases.
Staff estimates that the increase in contract limit of $250,000 will be adequate to co
the project. As Council is aware, the contract is in litigation and a number of issues
in dispute. Any judgement found in favor of the contractor and litigation costs
require additional expenditures in the future.
