Re: Change Order #3 for Mission Avenue Improvement Project, CIP #0123
1. Describe the Change This change order reconstructs the west side of Greenacres Rd from Station
8+13 to Station 10+25 with a 4" HMA / 6" CSTC section. From Station 10+25, RT to Station 11+00,
RT, this change order paves back 2 inches of HMA over existing crushed surfacing.
Evolution of the Change The bid design plans call for reconstructing the east side of
Greenacres Rd (northbound lane) after installing a storm drain pipe P-32 from Mission Avenue
north to a stormwater swale. During construction, the alignment of pipe P32 was relocated two
feet west to get by an existing Centuryl-ink communications vault. The western edge of the
resulting trench extended beyond the Greenacres Rd centerline. The existing lane width is 10.5'
wide. The Pavement Cut policy requires repaving at least to the centerline of the southbound
lane. However, rather than leave a 5 foot wide strip of existing pavement on the west side, the
entire southbound lane will be replaced.
From Station 10+25 to Station 11+00, the existing 2 inch HMA section was removed to allow a
taper to be constructed. In this section, the underlying crushed surfacing has not been disturbed
by utility construction, so this change order will just pave back 2 inches of HMA over the existing
crushed surfacing.
3. Payment The cost of this change is based on the following contract unit prices.
18 Roadway Excavation, Incl. Haul 82 CY $20.50 $1,681.00

Total $10,962.30

centerline, from Station 10+25 to Station 11+00.
