1. Surveying Services - The Consultant shall provide all labor, equipment and materials to prepare mapping and complete the design of all elements of the project. The Consultant shall: a. Perform research of existing records b. Establish a horizontal control network c. Establish a vertical control network d. Conduct a topographic survey e. In coordination with the County Surveyor: i. Recover and tie monuments of record ii. Resolve road centerline alignments and road rights-of-way iii. Prepare and file a Recovery and Retracement Survey Map iv. Prepare the right-of-way base map 2. Design Engineering Services - The Consultant shall provide all labor, equipment and materials for the development of engineered Public Improvement Plans. The Consultant shall: a. Prepare a geotechnical design report that will include: i. Feasibility analysis of retaining walls/rock slope excavation & stabilization required to construct a new roadway prism within the existing right-of-way, based on geotechnical site characterization. ii. Retaining wall and/or rock slope stabilization design alternatives. iii. Planning level cost estimates for each design alternative. v. Findings and recommendations for a preferred design alternative based on cost, constructability and right-of-way constraints. v. Feasibility of salvaging existing roadbed materials within the new roadway prism. b. Utilizing AASHTO, ODOT, MUTCD, and other applicable industry standards and best practices, produce road improvement plans for the selected improvements, including 30%, 90% and 100% plan sets for the preferred alternative, and refined construction cost estimates with each submittal. i. Note: Design of roadway and appurtenant features shall be based on most current adopted guidance, in conjunction with applicable local or state supplements. c. Design storm water runoff control and treatment per the Central Oregon Storm Water Manual. Identify necessary improvements to existing storm water facilities, if present. d. Develop temporary traffic control plans for the construction phase of the project. e. Prepare Project special provisions in reference to the latest edition of the Oregon Standard Specifications for Construction. The County shall provide template documents in Microsoft Word format to assist in the preparation of the Special Provisions. f. Provide an engineer’s construction cost estimate and complete bid schedule for the project. g. Provide appropriate construction period services necessary to answer all project-related questions as well as review contractor requests for information (RFIs) and submittals, as needed. h. Determine if there will be any utility design and relocation required as part of the project, including, but not limited to, underground and overhead power and communication line relocation, canal piping, and any other utilities that fall within the project limits. Coordinate relocated and new utility alignments within the Plans and Special Provisions as necessary. i. Prepare a Design Technical Memorandum to document criteria used for engineering design. This may include justification for any necessary deviation from criteria set forth by state or federal engineering design standards (e.g. ODOT, AASHTO, MUTCD, etc.) or by Deschutes County Code. The County anticipates that design exceptions may be required based on site-specific constraints. j. Note: i. Road and other project components shall generally be designed to current AASHTO and Deschutes County standards and specifications. ii. Contract Documents shall incorporate the most current Oregon Standard Specifications for Construction anticipated at the time of bidding and applicable Deschutes County and ODOT standards. 3. Construction Engineering Services - The Consultant shall provide all labor, equipment and materials to provide appropriate construction period services necessary to answer all project related questions as well as review the contractor’s product submittals.
