George,
You can disregard the email I sent you yesterday (or file it away)….it really should have gone to Keith Marvin. I was
confused and thought you made the comments that I needed more input on but it was Keith. Keith worked out the
comments with me this morning.
Sorry for all the confusion,

Subject: Sandy Lake Addendum #2
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?
1
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.
