Consider approval of awarding Bid/Contract #Q-0204-02 for the construction of the
Shadow Ridge Estates Retaining Wall project to Craig Olden, Inc., in the amount of
$81,300 as funded in the 1999 Capital Improvement Program; and authorizing the City
Manager to sign.
On April 20, 2004, the City of Coppell received and opened three bids for the reconstruction of a retaining
wall within the Shadow Ridge Estates subdivision. The retaining wall in question is immediately east of
the intersection of Plantation Dr. and Southern Belle Dr., and immediately south of the alley along the
southern edge of the Wynnpage subdivision. The current retaining wall is a cross-tie retaining wall, which
is the main support for the alley within the Wynnpage subdivision. While the greater concern with the
existing retaining wall today is the potential failure and damage to the alley in Wynnpage, this area was
also identified in the 1991 City Wide Storm Water Management Study as an erosive area that needed
attention. This was before the construction of the Wynnpage subdivision to the north. This project was
also identified by the Bond Advisory sub-committee for inclusion in the bond election of 1999.
The apparent low bidder on the project was Vortex Construction Company in an amount of $67,168.
However, upon review of their bid proposal it was noted that they had made errors on six pay items. Those
six pay items all dealt with the unit price for quantities, as opposed to lump sum pricing. Using the unit
price contained within the Vortex bid and multiplying it times the quantity, gives the adjusted prices as
shown on the attached bid tabulation. Utilizing the adjusted prices, Vortex's bid comes out to $94,298.
Even if their intent was $67,168, the language within the specifications states that the unit price times the
quantity is the method to obtain the actual bid. The specification specifically state under award of contact
"discrepancies in the multiplication of milts of work in unit prices will be resolved in favor of the unit
prices". It also states that "discrepancies between the indicated sum of any column of figures and the
correct sum thereof will be resolved in favor of the correct sum". So therefore, again utilizing the unit
price and tabulating the correct sum, Vortex became the second low bidder, not the low bidder.
Therefore, the lowest qualified bidder on this project was Craig Olden, Inc., in the amount of $81,300. The
project itself is a gabion wall and Craig Olden, Inc., is the industry leader in the construction of gabion
walls.
Staff recommends the award of the Shadowridge Estates Retaining Wall project to Craig Olden, Inc., in the
amount of $81,300. Staff will be available to answer any questions at the Council meeting.
