Based on our meeting with the railroad, the design will require a short term, temporary closure of the railroad line and pre -cast box culverts will be used. I. S - Geotechnical Investigations: Geotechnical investigations will be completed by Terracon and will include engineering data to complete the design of the improvements. Work completed by Terracon will be contracted separately with the City. I. 9 - Preliminary Design Submittal: When the design is at about the 60% complete phase, we will hold a Preliminary Design Submittal meeting wherein we will present to the City the results of our work to date. In essence, this meeting will be a formalized progress meeting at which representatives from the various City departments, utility owners, and City staff will be given a detailed "tour" of the future project. This will be a good opportunity to conduct value engineering analysis, and to gain the insight of others that are not in day to day contact with the project. Primary work items to be covered as a part of this task include: • Summarize final hydrology • Discuss any potential altematives • Provide costs • Present plan of improvements • Discuss residual floodplain • Discuss construction issues • Discuss phasing options • Obtain design review comments from the City In order to facilitate the review, we will provide ten sets of the drawings in advance of the meeting. We will also provide one set of mylars so the City can make additional copies as needed. II. FINAL DESIGN II. 1 - Coordination and Project Meetings: During the Final Design Phase, we will attend three additional coordinationlprogress meetings. II. 2 - Detailed Construction Drawings: After obtaining comments and gaining approval of the preliminary design, the construction drawings will be prepared. For purposes of this proposal, it is anticipated that all improvements will be built in a single phase with a competitively bid contract Final Design Drawings will be prepared in accordance with City Standards and include all items necessary to complete the construction of the proposed improvements such as plan and 0 i Apropos allftcollin\hcwesfl.doc profile drawings of the culvert, street improvment profiles and details, utility relocation designs and water quality improvment pond details. The plans will also delineate the existing and proposed right-of-way lines with the names of the property owners, existing and proposed easements, existing and proposed utility improvements and relocations, existing and proposed structures including fences, culverts, and buildings, existing and proposed property access configurations and improvements, construction disturbance limits, and proposed revegetation limits. The proposed structures will be designed in accordance with the latest edition of CDOT Construction Standards or individually designed by our structural subconsultant. The plan and profile will depict the vertical design elements of the project and include the existing and proposed centerline grades, limits of construction and elevations of tie-in points to existing improvements, existing and proposed underground utilities and drainage improvements, as applicable. Structural engineering will be finalized to include structure dimensions, required reinforcement, and miscellaneous structural details. Traffic control plans will be prepared for construction of the project. Plans will be required for several different areas in order to facilitate construction access of other City projects. Erosion control plans will be required for the project. Since most of this construction is not within an active stream channel, most of the erosion control structures will be in the lower portion of the reach near the water quality pond and the Poudre river. Following review by the City of the final design, we will incorporate review comments and prepare a final layout sheet. We will provide final mylar drawings to the City. All drawings will be prepared utilizing AutoCAD v. 13. Both hard copies and electronic files will be given to the City. It is understood that the final construction drawings and documents will be reviewed by the appropriate City Departments prior to bidding. II. 3 - Right -of -Way Analysis: Property ownership and property lines will be determined along the route of the selected improvements. The City will provide Title Reports as required for writing legal descriptions. The project team's survey manager will prepare property descriptions along with exhibits defining the boundaries and area of property to be acquired. We will prepare up to five permanent easements and five construction easements for the project. This information will also be shown on the design drawings. II. 4 - Contract Documents: We will provide mylar drawings of the final construction plans and originals of the specifications for reproduction. We will provide 50 sets of the specifications and drawings and transmit them to the City for distribution to bidders. The City will advertise the project. Specifications will be prepared using Microsoft Word for Windows 95. Both hard copy and electronic copies will be provided to the City. The City will provide the standard "Boiler Plate" contract documents to complete the specification package. Technical specifications will be prepared to cover all construction items using CSI format. The Technical Specifications will be designed to stand alone, i.e. not require separate reference documents. It is 5 is\proposal\ftcollin\howesfl. doe understood that although they are specifically for this one project, the Technical Specifications will be utilized as standard specifications on other City projects. This will require that the specifications be written in a generic manner with respect to location of installation such that they will be useful on other similar applications. The Technical Specifications will be reviewed by the City for use in future projects. Consequently, our proposal includes conducting two meetings (not included in other tasks) with appropriate City staff to gain feedback and general agreement with the intent and format of the specifications. I1.5 - Final Floodplain Analysis: Following the final design of all project improvements, the preliminary floodplain analysis will be revised to reflect all changes/modifications to the preliminary design drawings. For the purposes of this scope of work, it is anticipated that minor changes/modifications to the preliminary analysis and mapping will be completed. 11. 6 - 404 and Other Environmental Permits: We will prepare and obtain the environmental perrnits necessary prior to construction of the project. This work includes preparation/submittal of the Section 404 permit application. The City has already completed the "Rare and Endangered Species" surveys whilch will be used for the application. The contractor will be responsible for preparing and obtaining the 401 permit. H. 7 - Finalize Railroad Permit: This task will include refining the permit submitted during the preliminary phase, obtaining railroad comments, addressing the comments and obtaining the final permit. Specifically not included are any fees payable to the railroad for the review and/or granting of the permit. If the railroad does require fees, they will be payable directly by the City. 11. 8 - Quantity and Cost Estimate: Included in this task will be an updated quantity tabulation, along with an Engineer's estimate of probable construction costs. We will tabulate individual quantities of such items as earthwork, concrete quantities, curb, gutter and sidewalk, storm sewer pipe, riprap, grouted riprap, landscaping features, and asphalt. Estimate costs of these items will be based on City, County, and other project cost data. 11. 9 - Final Design Report: Four copies of a Final Design Report and Addendum will be prepared by the project team. This report will document major changes or revisions from the decisions made during the Conceptual Design phase. Documentation and text related to the hydraulic evaluation/floodplain analysis will be provided for the final design report. This work includes preparation of floodplain mapping within the study area. 1 Aproposal\ftcollin\howesfl. doc III. ENGINEERING SERVICES DURING BIDDING We will assist the City during the bidding and contract award period and will provide contract administration services including printing contract documents, attending the pre -bid meeting, answering contractor questions during bidding, preparing addendums, attending the bid opening, and making contract award recommendations. III. 1 - Drawing and Contract Document Printing: Included in our proposal is the printing of 50 copies of full-size blueline sets of drawings and the same number of bound Contract Documents. The sets will be turned over to the City for distribution. The City will be responsible for advertising for the project. Along with the hard copies, we will transfer to the City electronic copies of both drawings and the Contract Documents. Additionally, original mylars of the drawings and one set of original, unbound Contract Documents will be provided.

PRELIMINARY DESIGN I. 1 - Coordination and Project Meetings: The project team will be responsible for coordination of the design review process with the City and other interested entities such as utility owners and adjacent property development and will be responsible for submittal of the design products to each entity. Direct communication with representatives of each entity will be established by the City's assigned project manager and schedules established for the timely review of the work products. Members of the project team will participate in several meetings associated with the proposed project. We will coordinate with the City's project manger to establish an agenda for each meeting and prepare the necessary handouts and exhibits to ensure that an effective meeting is conducted. We will identify those key personnel necessary for attendance at each meeting. A summary of the meetings is described below. A. Initial Kickoff Meetino: This meeting represents the culmination of the Conceptual Design process. This initial effort will result in an effective meeting which will include discussions of: (a) project goals and objectives; (b) project scope and budget; (c) project schedule and identification of milestones; and, (d) contact person(s) for each department/agency. Work assigned to each subconsultant will also be discussed at this meeting. B. Progress Meetings: Progress meetings will be scheduled as required during the completion of the design. Our fees assume five project meetings during this phase. The project team's project manager, along with key members of the project team, will attend depending on the topics for discussion at each meeting. C. Coordination Meetings: Three meetings are included to coordinate with affected utility companies and adjacent property development. Initial coordination efforts will be completed by the City's project manager to inform the entities of the proposed design elements and to set meeting times. Meetings will be held to discuss requirements of the project and to obtain input from utility owners, City departments, and adjacent developments to help formulate the design. Additional comments from the utilities will be solicited by the project team through the City's existing utility coordination process. 1 i 9proposal\ftcol I i n\howesfl. doc I. 2 - Detailed Project Mapping: Initial survey control and preliminary mapping was previously developed for the general project site. Now that the conceptual route study has been completed, detailed mapping will need to be completed. The new mapping will utilize the previous mapping to the extent possible, but will include strip mapping along the project alignment and additional details of existing improvements. Mapping previously developed in the lower reach near the Poudre River will be used for the design supplemented by field elevations. I. 3 - Finalize Hydrology Flow Split: This work involves the detailed investigation of flow splits at several intersections which convey flow to the outfall. Survey data at each intersection has been collected and will be followed by completion of a hydraulic evaluation of the flows which will be integrated into the hydrologic model. This information will be used to determine actual flows which will get to each intersection. The hydrology work for this task will be completed under a separate contract with the Utility. Coordination and review effort as it pertains to Howes Street is included in this scope. I.4 - Hydraulic Analysis: A. Complete Preliminary Hydraulic Evaluation/Floodnlain Delineation: Following the preliminary design of the outfall channel, a floodplain analysis will be completed to determine the limits of the floodplain adjacent to the proposed improvements. This floodplain will be based on 100-year flows for developed conditions with proposed master plan facilities, meaning diversion of 300 cfs at the Canyon Street/Magnolia Street intersection upstream of the Civic Center Outfall (Howes Street). Mapping of the floodplain will be limited to the corridor encompassed by LaPorte Avenue to Cherry Street, Maple Street to Mason Street, and from Cherry Street to the Cache la Poudre River. The floodplain will be delineated using HEC-2/HECRAS. Since no floodway is required for this basin, no floodway will be delineated. Drawings will be prepared which will incorporate the floodplain delineation on the detailed contour mapping developed during the project. The location and orientation of all cross sections used in the hydraulic computations will be provided on the mapping and specific cross sections of crossing structures will be generated. Typical cross sections illustrating 100-year flows and velocities will be included along with a 100-year flood profile along the alignment of the outfall improvements. A tabulation of flood hazard information will be prepared for each cross section. This information will include cross section number, reference line stationing, 100-year discharge water surface elevation, thalweg elevation (where applicable), energy grade line elevation, top width of floodplain, and both mean and segmented velocity data (where applicable). I iAproposal\ftcol I iftowesfl. doc B. Inlets and Box Culvert: Hydraulic gradeline for the design flows will be evaluated as well as inlet/street capacity. Inlets will be sized using an agreed upon depth of inundation and an assumed partial blockage of the openings. Final hydraulic analysis will be completed for sizing the box culvert assuming final flow splits and considering pressure versus open channel flow as well as a super critical flow regime in the box. I. 5 - Utility Relocations: A. Pothole Information/Surveys: We will assist the City in obtaining utility locates including surveying critical utilities that will be exposed during potholing excavations. It is assumed that the services of the survey crew will be minimal and will include shooting benchmarks established for the potholing and establish elevations based on measurements to the utilities A total of 16 hours of survey crew time is assumed. B. Utility Relocation Design: This task is inclusive of the design of modifications to existing water, sewer, and storm sewer pipes (both main lines and service lines) that may be required to facilitate the completion of the outfall system based on the Conceptual Design Plan. Lowering the City's fiber optics line is also included. Additional utility design modifications would require an adjustment in fees. Specifically not included in our scope are costs to design gas, phone, cable TV, and electrical system modifications which are assumed to be completed by the utility owners. I. 6 - Refine Conceptual Design: A. Plan and Profiles. Plan and profile drawings will be completed to include the new mapping details, potholed utility modifications, updated sizes for facilities, inlet and street modifications, general notes, and grading. B. Details: Structural investigations/design will be conducted under a subconsulting agreement with Bates Engineering, Inc. During preliminary design, structural engineering involvement will be limited to assisting in estimating cast -in -place wall thicknesses and other physical dimensions such that preliminary quantities can be determined, and it can be confirmed that there is physical room for the planned improvements. Landscaping details will be provided under a subconsulting agreement with Jim Sell Designs. Landscaping opportunities along the upper portion of the project are very limited and only include providing a sodded area along the north side of Laporte Avenue. Along the lower portion of the project, through Martinez Park, in the water quality pond and the river floodplain area, landscaping and revegetation plans and details will be required. C. Preliminary Cost Estimate: Based upon the refined conceptual design, we will prepare a construction quantity take -off and unit price estimate. Costs will be based upon quotes supplied by major materials suppliers (particularly for pre -cast pipe/box) and recent bid costs for similar work items. is\proposahftcoflin%howesfl.doc 3
