WCD-001 did not add any calendar days. Justification: Prior to the start of construction, the City's consultant performed an examination of the East Clearwell using ground penetrating radar. The ground penetrating radar identified a possible void under the floor slab in an area where past settlement of the clearwell wall had occurred. The City had our design-build contractor core a hole through the slab in the area of the possible void. The foundation material under the slab was probed to check for a void and to confirm the material was consolidated. WCD-001 covers the additional costs to core the hole and repair the hole using reinforcing steel and placing new concrete in hole. Work Change Directive — No. 002: Install Handrail on the North Bridge Abutment: WCD-002 is a lump sum revision for $3,750.00. WCD-002 did not add any calendar days. Justification: The project scope included the removal and replacement of the bridge between the south dam and the Screen House intake structure. The old bridge and abutment were 20-feet wide. The new bridge is 6-feet wide. This left 14-feet of fall exposure along the existing abutment. The added handrail will protect personnel from possible falls. WCD-002 covers the additional costs to fabricate, galvanize and install the handrail. Work Change Directive — No. 003 — Revise Floor Repair Area: WCD —No. 003 is a lump sum revision for $59,468.07 and the addition of 10-calandar days.
