Local Public Agency: City of Waterloo
Date Prepared; October 2, 2020
You are hereby authorized to make the following changes to the contract documents,
A - Description of change to be made:
I. Delete asphalt wedge;
2. Modify Lump Sum Signalization
a. Replace the specified camera detection camera with an ITS camera;
b. Delete painting of signal poles;
c, Delete mast arm signing;
d. Delete traffic signal loops;
e. Delete two (2) loop handholes;
f Add three (3) LED Red Bill Melt Smarts;
3. Delete pavement markings;
4. Delete Pavement Markings Removal.
B - Reason for change:
1. This asphalt wedge was to provide transition from new pavement to greyhound pavement. However, Greyhound has been
contracted to be overlaid at the same time as out project. The contractors have coordinated then' work. The wedge is no longer
needed as the overlay will meet our project's new pavement.
2,a, '1'o improve detection and reduce unnecessary loop detectors. The specified detection system is a dome coiner -mounted single
camera video detection. It can detect only 300 feet from the interscction. Dilemma zone advance detectors are placed farther than
300 feet. Using the dome camera requites installing detector loops to cover advance detection needs. The donne is not good at
detecting a far lane when the near lane has a truck in it. Possible future adaptive operation requires detection at each individual lane.
Mast arm pole mounted detection cameras to replace the single donne camera will have the ability to detect much farther back
eliminating the need for loops.
2 b. Water loo poles are normally not painted. Waterloo uses painted poles within special enhancement corridors and in the
downtown area. Paint was inadvertently left in the specifications from a previous project.
2.c. Mast arm signing can be done in-house to reduce project costs. The City a modern sign shop and can make all types of signs.
2.d. With new video detection system loops no longer needed,
2.c, Loop handholes not needed when loops are eliminated
2.f Three (3) snow melt LED red single solid ball signal heads (1 towards each approach) with snow/ice melt capability is a safety
impt ovement
3. Markings can be done in-house to save project costs. Late fall/early winter and cold/wet weather pavement markings normally do
not survive the winter. The City will probably have to redo the markings in the spring anyway.
4. Markings removal can be done in-house to save project costs.
5. Delete Item No, 15, Storm Sewer Manhole, SW-401, 48 in. and replace with two (2) 15" RCP prefabricated storm sewer bends.
C - Settlement for cost(s) of change as follows with items addressed in Sections F and/or G:
I. Delete asphalt wedge: Deduct $4,770.00
2.a. Replace specified camera detection: Deduct Lump Sum $10,000.00
2.b. Delete paint on signal poles: Deduct Lump Sum $5,000.00.
