B. Various plan revisions (alterations) required during construction, with no
"extra work" and utilizing existing bid items.
1 . New manhole MH N-64P was constructed approximately 5 feet west of
planned location to keep from obstructing existing drainage ditch on
Forrest Street.
2. Line 9-2" from Station 7 + 00 to Station 0 + 02.5 on Ewing Street was
relocated from under existing street pavement to behind the street curb
and another manhole, MH N-79P, installed.
3. Line "E" (12" force main) was installed at various lower elevations
along the route from Station 0 + 38 to Station 6 + 93 and Station 8 + 68
to Station 10 + 54 at the Contractor's request to facilitate ease of
construction and possible conflicting utilities. From Station 6 + 93 to
Station 8 + 41, the Contractor originally installed this section
generally in accordance with the plans; however that extreme pipe joint
deflections, due to a poor bore/case installation, resulted in the
inability of the force main from holding (passing) the hydrostatic test.
Subsequently, the Contractor decided to abandon this section of force
main and reinstall a replacement section at a high elevation using the
open cut trench method.
4. New manhole MH N-38P was relocated approximately 15 feet east of the
planned location in order to intercept the existing 6" sanitary sewer on
Stephenson Street. Additionally, the slope of Line "G" (8" sanitary
sewer) from Station 0 + 00 to Station 2 + 33 was reduced to .33% in
order to intercept the existing 6" sanitary sewer on Stephenson Street.
5. Line "F" (storm sewers) modifications consisting of the addition of two
new junction boxes, one new ditch inlet struction, deleting some
proposed storm sewer leads, and minor relocations of new storm sewers
were constructed to facilitate obstructions from existing utilities, a
building's overhanging canopy, and the discovery of previously unknown
existing storm sewers.
C. To increase the contract amount for "extra work" performed by the Contractor
for improvements constructed in addition to the contract plans, as follows:
1 . Additional asphaltic concrete overlay, 2 inches thick,
along Miller Street between Grant Avenue and Willow
Street, in accordance with the Contractor' s letter dated
July 31, 1987: 15.8 S.Y. @ $8.25/S.Y. +$ 130.35
2 . Additional street pavement consisting of reinforced
concrete curb and gutter section, approximately 2 feet
wide, on Miller Street between Grant Avenue and Willow
Street, in accordance with the Contractor's letter
dated July 31, 1987: 78 L.F. @ $16.00/L.F. +$ 1,248.00

+$ 300.00

5. The originally proposed conduit run "IP" and wire

1 No. 2, in accordance with the Contractor's
letter dated July 31, 1987: Lump Sum +$ 880.00
6. A clean sealant coating was applied to the cement
masonary block walls for the Long Street and Grand
Avenue Lift Station to prevent moisture penetration ,
in accordance with the Contractor' s letter dated
July 31, 1987: Lump Sum +$ 357 .50
7. A previously unknown 2' x 4' existing storm sewer
cast-in-place box culvert under Magnolia Street at
Miller Street was unavoidably damaged during the
installation of the new 15 inch sanitary sewer. The
additional cost to make these cast-in-place repairs
and maintain traffic control is in accordance with
the Contractor' s letter dated May 31, 1987:
Lump Sum +$ 4,830.20
8. The proposed 100 SCFM ventilator for the Long Street
at Grand Avenue Lift Station was changed to a 750 SCFM
ventilation to conform with State Design Criteria.
This additional cost is in accordance with a letter
dated September 16, 1987 from the Contractor's lift
