RE: SH 121 Water Line (Coppell Road to Denton Tap Road)
WA 01 -01
Final Review Comments
Dear Mr. Hendricks:
Following a review of the above referenced plans and specifications, the following
comments are offered for your consideration:
PLANS:
General Comments
1. The plans as presented do not appear to be buildable. It does not appear that an
effort was made to avoid existing utilities. The City will not be relocating the
existing overhead electric transmission poles. They need to be avoided. Was any
other route considered that would allow for a buildable project?
2. You have stated that the City will most likely be responsible for the burden and
cost of relocating existing utilities that conflict with the proposed construction of
the water line. You have also indicated that there is a good chance the
underground and above ground electric lines will conflict with the proposed
alignment. Based on your "on the ground survey" you should be able to
determine the conflicts with a greater degree of certainty other than "good
chance ". It appears that ± 5000 linear feet of electrical utilities, ± 1050 linear feet
of gas line, and five or more power poles or lights may conflict with the proposed
alignment. Can the number and length of utilities that conflict with the proposed
alignment be accurately determined, and what is the estimated cost and time
associated with relocating these utilities? As stated above, the City will not
relocate the existing electric transmission poles. They should be avoided. The
cost of utility relocations has not been included in the estimated construction cost.
3. Have the plans been provided to all utility companies and/or has there been any
coordination with other utility companies?
4. What is the status of the TxDOT permits?
COVER SHEET
1. CITY COUNCIL — The City Council list needs to be updated as shown.
SHEET NO. 1
1. NOTE 2 — The Storm Water Pollution Prevention Plan shall conform to the Texas
Commission on Environmental Quality regulations and not the EPA.
2. NOTE 14 — Change "85% Standard Proctor" to "95% Standard Proctor ".
3. NOTE 20 — There are no barrier free ramps shown on the plans or in the bid
quantities. Can this note be removed?
4. NOTE 23 — Is the contractor required to meet TxDOT construction standards
since the installation of the water line is in their right -of -way?
5. NOTE 24 — Is the contractor required to notify TxDOT prior to the removal of
trees within the right -of -way. It appears that some large trees may need to be
removed (30 " oak).
SHEET NO. 2
1. Station 0 +00 to Station 1 +00 - the limits of the right -of -way have changed from
the 95% plans and the note referring to the removal of all concrete pavement
within the right -of -way needs to be revised.
SHEET NO. 6
1. A gate valve symbol is shown in the plan view west of the fire hydrant located at
Station 38 +00. It is not called for in the profile or in the bid quantities.
SHEET NO. 9
1. The construction of the Community Credit Union is complete. The note at Station
74 +59.60 needs to be revised. The proposed 8 -inch stub -out will not be plugged
but will be tied into the existing 8 -inch line.
SHEET NO. 10
1. Station 51 +32.94 (Line A) is shown for the intersection of Line B in the profile
view. On the plan view and on Sheet 7, Station 50 +43 (Line A) is shown for the
intersection of Line B. The profile note also refers to a 12 "x12" cross — that has
been changed.
2
2. Because of the delay, TxDOT has started construction of S.H. 121. Therefore the
open cut from Station 0 +85 to 3 +67 will most likely need to be bored also, at a
greater cost to the City.
SPECIFICATIONS:
General Comments
I. An updated set of boilerplate bid documents was provided to your firm to replace
the old version used in the preparation of the 95% complete specifications. It
appears that the final specifications still contain most of the old version and were
revised to incorporate the majority of our comments. The Supplementary
Conditions contain part of the old and part of the new bid documents. The
specifications need to be revised as necessary.
2. Need to provide more detail in the pay item descriptions.
The review set of plans and specifications can be picked up at our meeting on October
21, 2003 at 10:00 a.m. Should you have any questions or need any additional
information, please contact me at 972 - 304 -7019.
Sincerely,
Suzan C. Taylor
