Memorandum
Attached for your review and approval is a change order to the Construction Services Agreement with Precision Concrete, In. (Bid No. 4260) for the 2015 Sidewalk Repair Project.

A construction services agreement was approved by City Council on March 16, 2015 for a total authorized amount of $143,000.00.

Vertical displacements greater than 1 inch in height are generally considered to be too large for cutting and are typically planned to be removed and replaced with new concrete. By horizontally cutting sidewalk that is in otherwise good condition, full removal and replacement can be avoided. Based on the current unit prices for this year's ramp and sidewalk project, on average the cutting of one transverse joint will save the City about $164 per location compared to full replacement for a typical sidewalk slab.
Quantities of work for sidewalk repairs are based solely on engineers' estimates made at the beginning of the construction season. Field conditions determine the actual amount of work needed. Inspections in the field have found more opportunities to utilize this technology than previously estimated. This increase in authorized cutting quantities provides an opportunity to ext...
