Dear Ted:
This letter concerns the temporary patches placed around the
manholes and gate valves on the above-referenced projects.
The Specifications state: "After paving the base, all gate
valves and manholes on this project shall be adjusted to 3/4"
below finished grade for the winter. All disturbed aggregate
base shall be recompacted and the blacktop patched. A 3-foot
diamond of bituminous shall be placed around the manholes to
protect them from the snowplows. A one-foot diamond of
bi tuminous shall be placed around the gate valves to protect
them from the snowplows."
We have previously informed your subcontractor, Buffalo Bitumi-
nous, that the patches which they placed were neither diamond
shaped nor were they rolled properly so that a smooth surface
would be provided. We have also previously requested that either
they replace the patches with ones which meet the specifica-
tions, or lower the castings and gate valves to below the base
course for the winter. rt has now been almost 2 weeks since we
made this request, with no action on the part of Buffalo
Bituminous forthcoming.
We consider the temporary patches to be a safety hazard in that
they can (and have already) be pulled loose from the pavement
allowing the snowplow to collide with the casting or gate valve.
rf Buffalo Bituminous does not take immediate action to correct
this situation, we will find someone who will and deduct the
cost from your contract. Please be aware that any costs incurred
by the cities as a result of this situation, will also be
deducted.
