Date February 10, 2010 ATTACHMENT REHABILITATION OF TAXIWAY "B," TERMINAL APRON (PHASE 3A), TAXIWAY "A" EAST AND TAXIWAY "E" WATERLOO REGIONAL AIRPORT WATERLOO, IOWA FAA AIP PROJECT NO. 3-19-0094-38 (Proposed) I. PROJECT DESCRIPTION The project is described as the rehabilitation of Taxiway "B" from Runway 18-36 northwest to the existing PCC paved portion of Taxiway "B," the rehabilitation of the terminal apron (Phase 3A), the rehabilitation of Taxiway "A" East from the terminal apron area to Runway 12-30 and the rehabilitation of Taxiway "E" at the Waterloo Regional Airport, Waterloo, Iowa. The project involves the rehabilitation of the pavement section, replacement of the associated lighting system, marking and surface restoration. The rehabilitation of the taxiways will depend on the results and recommendations of the pavement evaluation. For the purpose of this agreement, it is anticipated that the rehabilitation will be accomplished by reconstruction or "white -topping" of the existing pavements with Portland cement concrete pavement. It is anticipated that this project will be funded by federal stimulus funds and require associated reporting. II. GENERAL PROJECT SCOPE The work to be performed by the Consultant shall encompass and include detailed work, services, materials, equipment and supplies necessary to provide preliminary design, develop final plans, develop specifications, provide construction cost estimates, and provide bidding services. Construction phase services will be determined after the project has been bid and prior to issuance to a federal grant. Work shall be divided into the following tasks: A. Design Phase 1. Design Conference - This task consists of a pre -design conference called by the City of Waterloo, Iowa (hereinafter referred to as Sponsor) and held between the Sponsor, the Consultant, the FAA and any other participating or regulatory governmental agency. The purpose of this conference is to define project requirements, finances, schedules, phasing and other pertinent data that affects the scope of work, design standards, presentation of preliminary and final plans and documents. The requirements set forth in this design conference will be confirmed in writing by the Consultant to the Sponsor, with copies to each participating unit of government. 2. Data Collection and Review — This task consists of the collection of existing data applicable to this project and related to the proposed work site. The Airport Master Plans, record drawings of completed projects, pavement design data, previous soil borings and soil data, and utility information will be compiled as background information for the project. 3. Subsurface Investigation — This task consists of completing pavement cores and collection of subsurface soils data on an approximate 400 foot grid along the Taxiway centerlines. The existing subsurface information will be used for design Page 2 of the terminal apron. Subsurface investigations shall be completed in accordance with FAA Advisory Circular AC 150/5340-6E. Subsurface information will be collected for design and construction of the proposed taxiway improvements. 4. Pavement Evaluation - This task consists of pavement evaluation of Taxiway "B," Taxiway "A" East and Taxiway "E." This evaluation will be performed to determine the current pavement condition and to provide background for the recommendations for long-term rehabilitation of this pavement. The rehabilitation will be based on a 20 -year extension of the useful life of the runway. A visual surface distress survey will be performed to define the type, severity, and location of distresses. Based on the survey the distresses will be quantified. This distress survey, coupled with data from the subsurface investigation, will be used to determine rehabilitation methodology. If the evaluation of the distress survey and the subsurface investigation are inconclusive as to the type of rehabilitation required, additional non-destructive and destructive testing will be recommended and undertaken by supplemental agreement to this task order. 5. Design Aircraft - This task consists of determining the critical design aircraft to be used for the design of this project through coordination with the Sponsor and the FAA. As part of this task, data will be evaluated to confirm with the airport sponsor the aircraft types and number of operations by occasional aircraft that use or are projected to use the Waterloo Regional Airport. A list of design aircraft and number of operations that form the basis for the pavement design and standard geometrics to rehabilitate the apron and taxiways will be presented with the pavement design. 6. Pavement Design - This task consists of summarizing the pavement evaluation, the determination of the design aircraft, and rehabilitation recommendations for the runway pavement design and preparation of the final pavement design forms for the project. The final pavement design forms will be based on the design aircraft identified from the previous section. 7. Field Survey - This task consists of a field survey to collect topographic, horizontal and vertical data to assist in the preparation of the plans for the project. Field data will be collected for the taxiway safety areas, including the taxiway lights. Property surveys are not included in this task. 8. Base Mapping - This task consists of the preparation of a topographic map including features, elevations, utilities, and contours of the project site. This map will be prepared from the field survey and record documents of completed projects. 9. Preparation of Design Plans — This task consists of the preparation of the final design plans for this project. The final plans will set forth in detail the requirements of the conceptual design phase, together with the common practice Page 3 of design and ethical practice of professional engineers. Plans will be prepared in compliance with current Central Region Federal Aviation Administration requirements in effect at the time the plans are prepared. This task includes the preparation of the following: a. Title Sheet b. Legend and General Notes c. Schedule of Drawings d. Schedule of Quantities e. General Project Layout f. Safety and Sequencing Plans g. Existing Conditions Including Safety Areas h. Typical Sections i. Removal Plans j. Geometric Plans k. Grading and Drainage Plans I. Paving Plans and Profiles m. Pavement Jointing Plans n. Pavement Surface Elevations o. Pavement Details p. Lighting Layout Plans q. Lighting Details r. Electrical Vault Modifications s. Pavement Marking Plans and Details t.
