To: Ronald E. Cox
City Manager
From: Mickiel G. Hodge, P.E., R.P.L.S.
Community Development Director
Subject: Traffic Signals at the intersections of Falling Leaf Drive
and Sunset Drive and W. Castlewood Avenue and Sunset
Drive
Contractor: Traffic Control Devices, Inc.
Contract Date: August 6, 1999
Original Contract Amount: $150,122.61
The above contract has been increased by the following amounts:
1. Additional materials and work required to install RCP culverts, a grate top inlet,
bedded in cement stabilized sand and backfilled to the elevation of existing
natural ground. The existing plans called for a culvert crossing of the sidewalk
traversing existing ditches on Sunset at its intersections with Falling Leaf Drive
and W. Castlewood Avenue. During the final inspection, it was determined that
the side slopes of the ditches at three separate locations were too steep and that
because of the depth of the roadside ditch, the existing ditch between the back of
curb and the new sidewalk should be filled. Also identified during the final
inspection, was the need to expand the pavement at the intersection of Falling
Leaf Drive to accommodate the turning radius of school buses using that
intersection. Attached, please find a copy of the proposal from the contractor for
completing this work. The total cost to address the items identified during the
final inspection is $15,520.84
2. Additional work is required to revise the signal timing at both intersections to
change the operation from split phasing to two-phase operation. The lenses in
four of the signal heads would need to be rearranged and then rewired in the
control cabinets. The contractor would perform this work for$1,014.24. This
change would allow for minimal delays to through traffic on Sunset Drive. It
would, however, also remove the protected left turn for Sunset traffic at both
intersections (refer to attached letter from TEI).
SUMMARY
Original Contract Amount: $150,122.61
Change Order No. 1, Add: $ 16,535.08
Change in Contract Time, Add: None
