RE: Sandy Lake Bridge (2)Keith,
As follow up to our meeting on site last week and e-mail below I offer
the following comments:
1. Potential Movement
a. The contractor should honor both the existing expansion joints
in the bridge/abutment (e/w).
b. The contractor shall provide adequate reinforcing and control
joints as required per City standard details.
c. A control joint should be provided at the end of the bridge
approach slabs/ roadway pavement tie-in where the section of median
patterned pavement is located on both the bridge deck and soil section.
FYI per City Standard Detail 2130, the median pavement is shown to be
doweled into the back of curb with #4 X12 “ @ 18” O.C.
2. Pay Item
a. The following sheets reference the median pavement
* Sheet 03 Typical Sections – contains the
following note for the bridge section “stamped concrete” in reference to
the median pavement.
* Sheet 69 Typical Bridge Section & Details –
contains following note “SEE LANDSCAPE PLANS FOR DETAILS” in reference
to median treatment on the bridge.
* Sheet 85 Miscellaneous Slab Details – contains
following note “SEE LANDSCAPE PLANS” in reference to median treatment on
the bridge.
* Sheet 116 Landscape Plan 65+50 – 69+50 provides
specific details/quantities for the median pavement design (±1929 sf).
b. All of the landscape elements for this project were bid lump
sum (LS). Other than the references previously noted, the details for
this work were provided on the Landscape sheets and should have been
accounted for as such in the contractors pricing for the project.
Please let me know if you need any additional information regarding
this issue.

Gentlemen,
We met with Tiseo and their bridge subcontractor today to discuss
several issues regarding the bridge. One issue that they are concerned
about is the decorative paving in the median. Some of their concerns
are:
1. The potential movement of the bridge from flexing or
expansion/contraction damaging the multiple pieces of different concrete
called for in the plan.
2. There does not appear to be a pay item in the project for
this decorative concrete.
Any thoughts on either of these issues?
Thanks.
