On November 2, 2004 a Pre -bid meeting was held. Subsequent to the pre -bid meeting, the City
of Coppell has received several inquiries concerning the referenced project. Listed below for
your review are the questions and our responses. Those items addressed by this addendum will
be considered as changes to the project.
1. This addendum modifies and extends the requirements of the plans and construction
specifications for the above referenced project.
2. Staple these addenda to the inside of the rear cover of the construction specifications or bind
it into the construction specifications at the end of the Bid Proposal.

CONSTRUCTION SPECIFICATIONS
1. Can office space be used in the vacant retail center at the southeast corner of Sandy Lake Rd.
and MacArthur Blvd. in lieu of a job trailer?
• Acceptable, but doubtful. The owner is an out of state owner and has been hard to deal with.
If permission is obtained, all utilities would need to be provided and a guarantee that it would
be available for the duration of the project.
2. Item #88 Finishing and placing stamped concrete is paid by the square yard. The
specifications state that payment shall be made on the basis of price bid per SY of stamped
concrete of thickness specified.
• All stamped concrete in streets will be 8 ". All stamped concrete in the medians and
driveways will be 6 ". The stamped concrete shown on the ramps is a separate bid item. Our
calculations indicate about 1,375 SY of 6" stamped concrete and 1,008 SY of 8" stamped
concrete. These quantities will be lumped together and bid at one price.
3. Will the successful bidder be allowed to use a cofferdam or sheet piling for dewatering?
• You must meet the requirements of you own SWPPP plan, TCEQ requirements and the
requirements of Nationwide Permit 14, which is included in the specifications. If you
propose to place a cofferdam upstream of the construction, that could be constructed of raw
dirt, provided that the upstream cofferdam is removed prior to removal of the downstream
facility. The use of unstabilized or uncontained raw dirt downstream will not be permitted.
The Contractor will be required to adhere to any agreements, mitigation plans and standard
best management practices required for the NWP14. If the Contractor makes changes in the
project construction method that would result in changes of project impacts to waters of the
U.S., the Contractor will be responsible for any new Section 404 permit.
4. Plan Sheet 55 of 94, note #3 references TxDOT standard drawing PC -5 for reinforcing and
joint details.
• Note #3 on Sheet 55 of 94, should reference TxDOT 11C -10 -23 dated December 2003.
5. There have been several inquiries concerning the sequencing of the multiple box culverts.
• The City will consider any sequencing of the construction of the box culverts that meets the
safety standards, traffic control standards, SWPPP standards, TCEQ standards, Nationwide
Permit 14 requirements, and the integrity of the box culvert or the roadway design is not
compromised. Any sequencing must also maintain two lanes of traffic.
