Project No.: OR PFH 46(13)

Project Name: Fall Creek Bridge Replacement

# General Technical Question Answer Date

1 x What are the insurance requirements for the project?

Since the concrete bridge deck is not the wear surface, will a bridge deck finisher be required to place the bridge deck concrete? Or can another type of vibrating screed be used?

Please refer to Section 107‐LEGAL

RELATIONS AND RESPONSIBILITY TO THE

PUBLIC . In the FP‐14 and contract Special

Requirements for insurance requirements.

Please refer to Section 552.‐ Structural

Concrete for finishing requirements and tolerances. An approved power driven finishing machine equipped with a screed that oscillates in a traverse direction is not required for surfaces underneath waterproofing membrane deck seal.

2 X Requesting information on layout of the temporary by‐pass roadway. The specifications section 650 – “Temporary Traffic Diversion” references the need for materials i.e. asphalt, crushed aggregate, unclassified borrow, temporary culvert pipe, temporary pavement markings and water. Further in the specifications the temporary bridge is to be 60’ with a width minimum width of 14’ and HL‐93 load requirement. Also referenced is a temporary culvert. The question is there is not a contract drawing showing the layout, route, or beginning and ending of the diversion.

Requesting a drawing showing the layout, orientation and bridge quantities that are required for the “Temporary Traffic Diversion”.

The temporary traffic diversion will be clarified in a forthcoming amendment.

5 X There doesn’t seem to be a bid item for the removal of the guardrail. I am wondering what bid item this would fall under, or if it is incidental to the G4 guardrail install item.

See Bid Schedule Item No. 20302‐1200

Removal of Guardrail.

6 X Inquiring if the detour bridge and roadway can be two way traffic instead of one way, this will eliminate the traffic light. The contract drawing show the traffic light as if the bridge is phased which will not be the case.

The Temporary Traffic Diversion is contractor designed. There are no restrictions on the Temporary Traffic

Diversion maximum width, as long as it fits within the Temporary Construction

Easement shown in the plans. Bid the project to provide the signal. If the need for the temporary traffic signal is eliminated as a result of the Temporary

Traffic Diversion design, it will be handled in a future contract modification.
