DATE:	APRIL 14, 2017

PURPOSE:	P.I. Report  

The preliminary field investigation for the subject project was conducted by    on      .  This project, which is (on / not on) the NHS, is for replacement / rehabilitation of the existing bridge on XXX over YYY.  (Provide a detailed description of the project limits, existing and projected traffic volumes, type of structures, proposed lane and shoulder widths, span lengths, etc. Describe any deficient features of the structure and provide details on how the decision to replace / rehabilitate was made.  Describe any constructability issues that may have affected the replace / rehab decision.  

Example of proposed condition
The proposed bridge will be a single span prestressed concrete slab bridge 55'-0" long and 39'-0" wide out to out.  The bridge will provide for two 12' -0" lanes and two 5' -4" shoulders.   MD XX is classified as a xxxxxxxx with a XX mph design speed and XX mph posted speed.  The proposed 5’-4” shoulders meet the SHA bicycle requirement, but do not meet AASHTO minimum shoulder width requirement of 8 feet.  To widen the shoulders to 8 feet results in environmental impacts requiring large amounts of tree clearing as well as right-of-way acquisition and would greatly increase the cost of this project.  Since the approach roadway in the vicinity of this bridge has no shoulders or minimal shoulders (2 to 3’ wide), it was decided that there is no benefit to providing the larger shoulders.  Since the design speed is less than 50mph, shoulder width is not a governing AASHTO design criteria and a design exception for the reduced shoulder is not anticipated.

The attached written comments from XXXX are hereby made a part of the report and will be incorporated in the Final Contract Documents unless otherwise noted in the body of this report.  If any of these issues have a significant impact on the project, then they must be highlighted in the body of the report (nobody will read the attachments except for the person who made the comments).

The following issues were discussed:
Maintenance of Traffic:
The PI Plans showed a preliminary Traffic Control Plan and Sequence of Construction that (has / does not have) concurrence from the District.  A detailed maintenance of traffic study (MOTAA) was performed to determine the overall impacts that the maintenance of traffic scheme will have upon the adjacent roadway network.  This study was sent to the District Traffic Engineer for approval and comments concerning any needed improvements to improve traffic flow.  Give a brief overview of how traffic is being maintained (detour, all through lanes maintained during construction, temporary bridge, pedestrian traffic, etc.).  Discuss any issues that were raised at the PI.  If traffic is detoured list any retail businesses that would be impacted as result of the detour.  Include the following (or something similar) when traffic will be detoured during the summer (or when through lane capacity will be reduced during construction).

The current plans have the bridge closed and vehicular traffic using a detour during construction.  This detour will be in place for a 10 week duration in the summer to avoid any impacts to school bus traffic.  Since this project involves closing mainline lanes of traffic, a public meeting will be scheduled for this project to give the community an opportunity to provide comments.
Practical Design:
Describe any considerations (implemented or rejected) relative to practical design to limit scope and investigate low cost solutions to address the need.  
Constructability:
Discuss the availability and need for staging areas for the proposed project.  Discuss options for access to the site as they relate to the need for temporary right-of way easements.  Ask for feedback concerning the Sequence of Construction shown on the PI Plans as it relates to Incentives for timely construction or other specific concerns.  If the plan calls for reduction in the number of through lanes during construction include the following (or something similar) relative to I/D clause.

As on similar projects utilizing a reduction in through lane capacity during construction, an incentive/disincentive clause will be recommended for inclusion in the Contract Special Provisions.  The incentive would encourage reopening this roadway within a ten week duration during the summer when schools are closed and a daily disincentive for everyday the bridge is not open to traffic after ten weeks would also support rapid construction.  The project will be advertised in the fall to allow sufficient lead time for ordering materials to meet the summer construction schedule.  
Right-of-Way:
The existing right of way limits have been designated by Survey and are indicated on the PI Plans.  Discuss any takes or easements required to facilitate the proposed project that were raised at the PI.  If there are no impacts say so.
Utilities:
The existing utilities have been designated by Survey and impacts to these utilities are indicated on the Plans.  Discuss any relocation or protection issues that were addressed at the PI.  If there are no impacts say so.  In cases where there are overhead lines on both sides of the highway, look into the impacts associated with relocating all to one side to facilitate future bridge inspection using the snooper vehicle.
Permits:
Discuss any relocation or protection issues that were addressed at the PI.  If there are no impacts say so.  Address the need for approval of Sediment and Erosion Control Measures, Stormwater Management / Waiver and Roadside Tree permit for less than 1 acre or mitigation for more than 1 acre.
Environmental:
The Maryland Historic Trust has reviewed the proposed construction and determined that the existing structure (has / does not) have historic significance.  Discuss any other issues that were raised at the PI.  If there are no impacts say so.
.
General:

1. (Each comment should indicate who made it and the disposition agreed to). 

Your earliest reply with comments and/or approval would be appreciated so that we may proceed with Final Plans. 

This PI Report documents our understanding of the issues presented at the PI meeting.  If anyone on the distribution list takes exception to the way in which their issue has been presented or resolved please contact our project engineer,  within two weeks of the receipt of this report.
