Consultant will meet with the City to review each submittal during design review workshops included under Task 1. Each submittal will address comments received from the City on the prior submittal. The 60% Design submittal will communicate to the City the Project design so that meaningful discussion can take place and the core Project decisions can be made as a group. Consultant will use a combination of written documents including the trenchless design evaluation and BODR, design drawings, manufacturers’ information, technical specifications, and other communication tools to allow the City an opportunity for significant input into the design process and to initiate the permitting process and utility agency coordination. Consultant will complete the following subtasks as part of the 60% Design Submittal:  Prepare Trenchless Design Evaluation/Recommendation: Led by Subconsultant Bennett Trenchless Engineers, Consultant will complete a feasibility analysis of at least three different trenchless construction methods. Potential methods, depending on the results of the geotechnical investigation, may include pipe jacking (i.e., microtunneling, auger boring, and open shield pipe jacking), pipe ramming, and HDD. Consultant will evaluate each of these methods and calculate settlement risk and jacking forces. Consultant will assess whether trenchless construction methods should be considered for additional sections of pipe beyond the railroad crossing. The evaluation will consider potential trenchless alignments and the locations of jacking and receiving pits as well as laydown areas. The results and recommended method will be summarized in a PowerPoint presentation.  Prepare Documents to Support the City in Obtaining Necessary Permits from UPRR and JPB: Consultant will prepare documents necessary for the UPRR and JPB permit applications, including the UPRR Exhibit “A” form for new pipeline crossings and other relevant design documents. This subtask will include general coordination with UPRR and JPB, with formal meetings included under Task 1. As discussed above, the City may consider asking UPRR to engage RailPros during the design permitting phase to understand the full scope of potential Project requirements.  Prepare 60% Design Documents: Consultant will prepare the 60% Design submittal that will include: o Plans:  Cover sheet with location and vicinity map;  General/construction note, abbreviations, legend, basis of survey sheets;  Plan and profile view sheets for both the trenchless and open trench sections;  Construction/recycled water details including relevant City standard details;  Connection details;  Utility crossing details;  Staging plan sheets;  Stormwater management sheet; o Technical Specifications:  Select City standard technical specifications;  Consultant-developed technical specifications; and o Opinion of probable construction cost (OPC).  Perform outreach to utility agencies and coordinate utility relocation: Based on the proposed design, Consultant will contact utility agencies that could be impacted by the Project and will initiate coordination for utility relocations, if required.  Prepare BODR Memorandum: Consultant will prepare a draft BODR Memorandum that documents the Project surface and subsurface site conditions, scope of the proposed Project, key design criteria, engineering calculations, construction schedule and sequencing requirements, product literature, and catalogue cuts. The other 60% Design deliverables and geotechnical report will be appended to the BODR. Task 3 Deliverables:  Trenchless Design Evaluation/Recommendation Summary Presentation in PowerPoint format and PDF  UPRR and JPB permitting documents in PDF format ATTY/AGR.2024.152/EKI Environment and Water, Inc.
