Project Initiation and Continuing Requirements 1 B. Engineering Design 2 C. Exclusions 3 INTRODUCTION This work order defines the AECOM efforts required to incorporate the 50% plan review comments into the status plan set. The tasks associated with this work order include: · Project Initiation and Continuing Requirements · Engineering Design A. PROJECT INITIATION AND CONTINUING REQUIREMENTS As part of the continuing requirements, AECOM will perform the following: 1. Progress Meetings. The City’s Project Manager and the AECOM Project Manager will be responsible for the day-to-day management of the Scope of Work. Specifically, the Project Managers will meet bi-weekly to cover the following: · Activities completed since the last meeting · Review of outstanding/late activities · Activities to be completed by the next meeting · Solutions proposed for unresolved and/or anticipated issues · Task order financial status and invoicing Progress meetings will generally be conducted as conference-calls, however occasionally it may be coordinated that in-person meetings can be achieved. A total of 6 (1–hour) progress meetings are included in this scope. It is assumed 2 meetings will be in the City’s office and the remainder will be conference calls. The consultant will provide monthly invoices to the City Project Manager stating progress on the project tasks and highlighting any issues of concern.

The Consultant will coordinate the work tasks being accomplished by the entire AECOM Project Team to ensure project work completion stages are on schedule. Project staffing and assigning of tasks, scheduling and invoicing are included within this task. B. ENGINEERING DESIGN As part of engineering design, AECOM will perform the following activities: 1. Survey Supplement Support. AECOM will coordinate with the City to identify/confirm the survey design needs. Survey design will be performed by the City and provided to AECOM as noted below: a. Topographic survey (to include utilities and existing right-of-way) of the following items: · Constructed embankment material prism north and south of Vine Drive/BNSF · Constructed CBC north of Vine Drive/BNSF · Storm drain feature locations at Lemay/Lincoln and Lemay/Buckingham intersections and the storm system from the neighborhood north of Buckingham to Lincoln b. 3D existing ground surface 2. Roadway Engineering. AECOM will perform the following roadway engineering tasks, as noted below, to incorporate the City’s 50% plan review comments into the current 50% status plans. Engineering required to advance the design further is not included in the scope but will be addressed in a future work order. This effort includes: a. Design Criteria. Review design criteria application and exception list created for 50% plan submittal, and coordinate with City staff to prioritize the exceptions. b. Revisions to horizontal alignment. This task includes alignment refinement at the north tie-in to achieve a higher design speed. Options discussed in the 50% review meeting will be evaluated and presented to the City for consensus. c. Simplify and revise the typical section template based on 50% review comments. Update the roadway reference file, the 3D model, and the proposed design surface to reflect the revisions. d. Update design of roadside grading and toes-of-slope. Revise the preliminary rough grading and earthwork quantities to reflect the embankment material placed north and south of Vine Drive/BNSF. e. Apply turning templates. Use AutoTurn to test and review turning movements at the signalized intersections (Lincoln, Buckingham, Suniga) to verify intersection layout. f. Plan Development. Roll plots and electronic 11x17 PDF’s will be utilized for reviewing and coordinating design revisions. Roadway plan sheets will be revised to reflect updated alignment and roadway layout. 3. Hydrology/Hydraulic Engineering. AECOM will perform high-level profile and capacity analysis for the roadside ditches, as discussed at the 50% plan review meeting.

AECOM will update the 50% landscape plans according to the revisions made to the rendering. 5. Major Structure Design. AECOM will finalize the abutment foundation design for the Vine Drive/BNSF Bridge to support the submittal to the BNSF Railroad. a. Update 50% abutment foundation design. AECOM will evaluate and update the abutment foundation design that is current in the 50% design plans with the results of the geotechnical investigation. Design results will be included in the submittal to the BNSF Railroad. b. Preliminary BNSF Railroad Submittal. AECOM will review and/or incorporate any City comments into the draft preliminary railroad support. Report will be prepared and packaged in accordance with the 2016 UPRR/BNSF RR Guidelines for Grade Separation Structures. c. Finalize Structure Selection Report. AECOM will update and finalize the structure selection report to reflect the abutment foundation recommendations from CTL Thompson. 6. Geotechnical Investigation. Using the prior soil boring data, for the geosynthetic- reinforced-soil (GRS) abutments of the proposed bridge to carry Vine Street over Lemay Avenue, AECOM Denver geotechnical staff will: a. Check bearing capacity and estimate settlement of the approach embankments. b. Check 2-D global stability of the embankments (section in the direction of Vine Street). c. Check internal stability of the embankments to establish reinforcement length and vertical spacing. d. Assist AECOM Transportation staff, if needed, with detailing of the attachment of the proposed boulder facing to the GRS substrate. e. Prepare a technical memorandum (estimated at 2-3 pages) summarizing the geotechnical analysis. C. EXCLUSIONS The following are not included in this scope and their inclusion is subject to a change in scope, schedule and/or fee: Value Engineering studies, survey, utility coordination and design, pot- holing, environmental, traffic engineering, phasing/MOT, SWMP, specifications, and right of way plans. These services will be provided under a separate task order as applicable. Environmental assumes FHWA/CDOT requirements are not applicable. END OF SCOPE OF WORK
