This construction contract focused on the second and third of four proposed landscaping
phases on West Coast Highway, extending from the City Oil Field entrance on the western
end to Newport Boulevard on the eastern end.
The work necessary to complete this contract consisted of clearing and grubbing,
removing embossed concrete paving, installing artificial boulders, plants and trees,
landscape establishment and maintenance, irrigation improvements and a staining
restoration treatment for the existing colored/stamped concrete located within the
medians.
The contracted work has now been completed to the satisfaction of the Public Works
Department. A summary of the construction cost is as follows:
Original Bid Amount: $975,350.50
Actual Cost of Bid Items Constructed: $861,907.00
Total Change Orders: $286,323.34
Final Contract Cost: $1,148,230.34
The contract originally estimated 36,495 square feet of old concrete highway pavement
removals that exists underneath the Coast Highway medians. During construction, the
contractor did not encounter concrete pavement to remove, but did however have to
export more unsuitable soil than estimated for the project. The additional soil export cost
totaled $96,723.91, which was largely offset by savings for non-existent concrete
pavement removal.
In addition, change orders for subgrade amendments and drainage improvements totaled
$61,425.49. Due to unexpected Caltrans emergency drainage work within the same area
of West Coast Highway, there were also change orders for cost of delay and revised
traffic control plan totaling $42,763.00. Further change order work included additional
irrigation improvements, replacement palms, artificial boulders and a price adjustment for
the imported topsoil bid item, all of which totaled $40,905.80. Lastly, there were two car
accidents during the course of the project, which required change orders to address the
necessary repairs. The cost of the two accident repairs totaled $44,505.14 and were
billed to the responsible party identified in the accident reports. With the completion of
the project, the final contract cost is approximately 17.7 percent above the original bid
amount.
