RE: CHANGE TO SCOPE OF WORK: UPDATE PLANS FOR RECONSTRUCTION OF SIDE WALK ON
NORTH SIDE OF SMITH STREET IN UKIAH TO INCLUDE ENTIRE WIDTH OF SMITH STREET
FOR A LENGTH OF APPROXIMATELY 300 LINEAR FEET.
Gentlemen:
This letter is to request an amendment to our Agreement for Professional Consulting Services, dated
August 10, 2010. The plans were updated in February, 2016, to bring the sidewalk and store entrances
into compliance with the latest Disability Standards. Then a walk-through was conducted with you to field
review the constraints and difficulties remaining after the sidewalk issues were resolved. As a result of a
constructability review of the sidewalk alone on May 4, 2016, it was clear that the street surface was so
irregular that it will not match the required grades of the new curb and gutter, which must conform to the
sidewalk. In addition, the existing pavement surface of one driveway on the north side will not conform to
the grades of the planned back of sidewalk and there is no way to modify the planned sidewalk grades in
a manner that they meet existing pavement grade and still conform to Accessibility Standards.
Therefore, it was the consensus that the entire street should be reconstructed, except for the curb gutter
and sidewalk on the south side which was done to current standards a few years ago and is not
deteriorating. As part of that reconstruction, a right of entry will be required to modify the way the
pavement on private property conforms to the new back of sidewalk. A concrete walkway to an entrance
to a building on private property must be raised to conform to the new planned grades for a distance of
approximately 5 feet in length.
This request for an amendment identifies four tasks which must be completed in order to put the project
out to bid.
Task 1 —Project Manaaement and Coordination
This task includes developing a scope of work to conform to the needs of the conditions on Smith Street,
review of work in progress with the City Public Works Department, and coordinating the work product for
delivery to the City Public Works Department.
The cost of this task is estimated to be$875.
Task 2—Plan Modifications
The plans must be modified to add the entire paved section of the street. Work will include developing a
centerline profile which will match the lip of gutter grades planned for the new sidewalk, curb and gutter.
Construction notes will be added to describe how the street work must be done.

City of Ukiah,Public Works Department June 10,2016
In addition, the westerly driveway on the north side of Smith Street must have a short transition designed
on private property to allow the paved area on the private property to conform properly with the new back
of sidewalk on Smith Street.
It is anticipated that the street improvement project can be done as an informal contract and formal
contract documents, including technical specifications, will not be necessary.
The cost of this task is estimated to be$4,400.
Task 3—Right of Entry
A construction right of entry must be obtained from the landowner to allow the City to have a contractor
work on private property to construct transitions which conform to Accessibility Standards at 7 doorways.
Also pavement on a private driveway must be constructed to conform to the new back of sidewalk over a
short transition area. These activities on private property must have a construction right of entry
developed with an exhibit showing the areas of entry.
The estimated cost of this task is$1,160.
Task 4—Construction Review and Testinq
During construction it is anticipated that there will be areas of the subgrade exposed which will require
special treatment. These areas will be reviewed by a geotechnical engineer from our firm. It is
anticipated that a geogrid such as TX-5 by Tensar will be recommended to be installed to assist in
bridging over the areas without significant sub-excavation and re-compaction. The structural section
recommended is 1.0 foot of aggregate base to support 0.4 feet of hot mix asphalt applied in two layers.
This structural section overlaid on a geogrid should be able to bridge over the expected soft spots. We
would observe and approve the condition of the subgrade soils prior to the installation of the geogrid, but
no compaction testing of the subgrade will be performed.
Compaction testing will be done on the surface of the aggregate base before the street is paved to assure
that the base has been adequately compacted. One maximum dry density test will be performed on the
aggregate base material to provide a proctor test for the compaction of the aggregate base. A proof-roll
test will also be conducted to assure a firm and stable surface has been established for the pavement
layers to be applied.
A brief letter report of conditions encountered and the results of the compaction testing will complete the
construction phase work.
The estimated cost of this task is$3,460.
Tasks Not Included, But Which Could be Added by Amendment
Formal construction documents are not anticipated to be required.
Construction staking is not included.
Aggregate testing of aggregate base and hot mix asphalt is not included.
Compaction testing of hot mix asphalt is not included.
Our"Schedule of Fees"for the original work was dated January 1, 2008. We have updated our Schedule
of Fees since then. "Schedule of Fees—Table 33" is attached with our current rates.
