My apologies Keith…I see you finally got the attachments from both Andrew and Robert this morning. I saw the e-mail
last night from Andrew with attachments (on my phone) and mistakenly thought he forwarded the attachments.
Again, sorry for the confusion…it was an oversight on my part as I did not have your e-mail address at the time I sent the
original e-mail.
Thanks,
Suki
P.S. Feel free to call me if you have any questions on the comments for the Addendum.

Suki/Robert,
Please include Keith on any traffic questions as he is in charge of the Sandy Lake project and was the
engineer that sealed the Denton Tap plans.
Thanks,

George,

The project team is preparing for Addendum #2 this week. I was wondering if you could
review a few items that were noted at the Denton Tap signal and the attached
markups/highlighted items. These items deal with the recent change to the City
furnishing the controller/cabinets at the 3 intersections and some City traffic related
comments that may not have been fully addressed prior to advertisement.
Denton Tap Signal
1.The V4LT signal head to be used for the flashing yellow prot/perm left turn
phasing does not match the signal indications per Figure 4D-12 of the TMUTCD
(attached). The red and yellow ball indications need to be swapped with
arrow indications.
2.Please be aware that these flashing yellow arrow signal heads are shown being
used in the EB/WB Sandy Lake Road dual left turn lanes. Just making sure that it
was the City’s intent to operate prot/perm flashing yellow dual lefts at this
intersection vs protected only dual lefts.
3.Per the Denton Tap signal plans, the video detection system, ILSN signs, and
Comm equipment are shown being re-used. Bid Qtys and Pay Item Descriptions
have been revised for clarity. The payment for re-using the video falls under 1-
124, whereas separate pay items 1-148 and 1-176 covers the Comm and ISNS,
respectively.
Technical Specs
1.Since the City is now furnishing the controller and cabinet. Please advise if
these sections (captions in red) in the spec are to removed or edited
accordingly.
2.There was an outstanding comment to include video detection and ISNS
sections in the spec (see attached comment). Does the City have internal specs
on these items to add to Addendum #2?
Pay item description/Qtys - Green Highlights are markups made for Addendum #2
1.The “clouded” comment sections are items that the City previously commented
on needing further attention.
2.Qty for pay item 1-146 Video Imaging Vehicle Detection System has been
reduced by 1, for a total of 2 to reflect its re-use at Denton Tap.
3.Cost of the controller and cabinets have been backed out of the 1-122 to 1-224
Pay Items. These Pay Item descriptions may need clarification to match any
revisions made to item 1 under Technical Spec listed above.
I have attached the electronic files of the pay items, tech spec, and cost estimate for
your use. Please feel free to mark up any revisions for inclusion into Addendum #2 set
for Monday 3/22.
Sorry if this is longwinded….feel free to call me if you need help deciphering all this.
