With respect to the strip seal expansion joint locations, DS Brown would like to substitute a 2” tall frame rail profile in lieu of the 1 ½” tall frame rail profile shown in the contract plans (drawing 23462). In order to accommodate the 2” tall frame rail profile, the C12 X 30 channel would need to be lowered ½”. Please confirm that D.S. Brown can substitute the Steelflex “SSA” frame rail (see attached) as an approved equal to the WABO Type E rail shape. In addition, please confirm that lowering the above mentioned channel will not have an adverse effect on the rest of the structure since the joints are located at hangers.

Plan sheet B1 references a Concrete Class - Structure quantity at Bents 2 and 3 of 6.2 CY each. Plan sheet B5 shows the structural details for work performed at Bents 2 and 3. The only Concrete Class - Structure showed at these locations are the new bearing pedestals. Based on the dimensions provided, I come up with substantially less concrete quantity than the plan summary (I get 1.2 CY per bent location). Please review plan and bid quantity accordingly.

Standard plan SBR-BRR contains details for 4" conduit in barrier with note to omit "on interstate structures".  It is unclear based on this note whether this 4" conduit will be required on this project.  Please clarify. If it is required, is it required in one barrier run, or both?
Answer
Submitted: Thursday 05-APR-2018 10:28 AM
Conduit is required in the barrier on both sides of the bridge.  Include all costs associated with furnishing and installing 4" diameter PVC conduit pipe in the unit bid price for Barrier Rail- Cast in Place- BR.

Section 409.01.1 provides that MDT will suspend contract time after August 20 if the only remaining work is seal & cover and pavement markings. This doesn't really work on this project with it being a fixed completion date contract (August 31). With a start date of July 09 and the amount of bridge work to complete, performing the chip seal prior to August 20 is not really an option. The work can't be done until the new deck is out of cure and has enough strength to drive on. According to pavers, MDT will sometimes allow chipseal work to happen after August 20, but they are reluctant to do this work after the August 20 date due to warranty issues and the risk of colder nighttime temperatures affecting the finish product for which they have no control over. Section 620.03.7 requires a 30-45 day wait period between interim pavement marking and final epoxy striping. This certainly does not work with the specified start and finish dates on this project. Please clarify how the chipseal and epoxy striping work is to be incorporated into the contract specifications and specified completion date. If time is to be suspended and the roadway opened to traffic, please clarify how traffic control and required flagging for these operations would be handled.
