SUBJECT: City Manager - March 23, 2007
ITEM: Action authorizing the City Manager to execute Change Order # 1
with Manley Contracting for Dell East Campus Channel Repair.
Department: Engineering and Development Services
Staff Person: Danny Halden, P.E.
Justification:
The original contract with Manley Contracting was approved by the City Council in December
of 2006 for $166,385.00. Due to unforeseen circumstances, the original scope of services
has changed, and Change Order # 1 is requesting an increase of $24,179.50 bringing the
total contract amount to $190,564.50.
Funding:
Cost: $24,179.50
Source of funds: 2002 G.O. Bonds
Outside Resources:
Alan Plummer Associates, Inc.
Background Information:
Upon excavation of the deteriorated concrete channel lining, the sub -grade was found to be
extremely poor and groundwater seepage has created constructability issues. This change
order will provide additional measures to stabilize the channel bottom, to control ground
water, and to increase the structural capacity of the new channel lining. This change order
also modifies the spillway area of the abutting Dell pond that discharges at the end of the
channel. Dell and the City of Round Rock are funding these channel improvements with
each paying fifty percent (50%) of the construction costs.
