Field Staff Day is Ruined….
•
Base Patching/ Concrete Repair projects usually…
•
Have the contractor show up unannounced with a large workforce.
•
Plenty of inspectors required.
•
Lots to measure / keep track of
•
Full Depth Sawcuts
•
Patch size.
•
Usually at least 2 mix designs running and being placed concurrently
•
Drilled Dowel Bars
•
Drilled Tie Bars
•
Quality checks to make sure work is being done according to plan.
Field Staff Day is Ruined….
Contractor will want to be paid for Tie Bars and Dowel Bars,
and will usually challenge the quantity for these items in the
plans.
Contractor usually forgets the word….
Drilled
We only pay for
Drilled
tie bars and
Drilled
dowel bars. The rest
are incidental.

•
See item 690.0250, Sawing Concrete for guidance on measurement
•
Contractor may want to argue the need for additional sawcuts
•
Contractor may want to argue that “everyone else pays for additional sawcuts”
•
Contractor may want to be paid for sawcuts along the asphalt shoulder.
Contractor will want to argue that the quantity of SHES
patches/repairs paid for is wrong based on which type of
patch has the higher price.
•
Keep good records on all patching/repair quantities
•
Keep good records on material used for each
patch/repair
•
Keep records on SHES patches/repairs placed for the
contractor’s convenience
.
When doing SHES work, it is becoming state practice to
do this work at night.
Field Staff Day is REALLY Ruined….
The SHES patches don’t set up and you have to open for
traffic!!!
