For estimating purposesIf needed, test coupons/samples may be taken for confirmation of existing structural materials and presence of lead based paint. Structurally, it is assumed generally understood that the roadway rehabilitated bridge will function the same as it does currently. With the walkway placed at the center of the bridge, the mini-piers will provide most of the walkway support from below; up through the repaired floor beams. The trusses will add limited support at the fascias of the rehabilitated bridge for outside limits of the walkway and the utilities, which will be closed during construction and a single detour plan will be implemented. The traffic control devices, proceduresrelocated inside of, and layouts shall be as per immediately adjacent to, the Manual of Uniform Traffic Control Devices (MUTCD)trusses. Preliminary Intersection Geometrics (L Sheets) Develop and refine geometric layouts and provide additional horizontal and vertical survey information needed to construct the intersections. The scale of these plans sheets will be 1”=20’. Preliminary Storm Drainage Design (M Sheets) Develop preliminary storm sewer layout and sizing Weldability is assumed for all proposed repairs based on proposed improvements and existing drainage patterns utilizing Chapter 2 of the SUDAS Design Manual. Resolve potential conflicts with underground utilities and other design elements. Vertical profiles are not developed as part of this task. The scale of these plans sheets will be 1”=20’. Preliminary Sanitary Sewer Design (M Sheets) No Sanitary Sewer is anticipated to be included as part of this project. Preliminary Water Main Design (M Sheets) Preliminary water main design layout including water mains and services based on proposed improvements and existing conditions. Identify staging/order of construction to ensure all services remain active as much as possible. Vertical profiles are not developed as part of this task. The scale of these plan sheets will be 1”=20’. Preliminary Removal Plans (R Sheets) This item consists of preliminary design and drafting of proposed improvements and removals. Preliminary Curb Ramp Design (S Sheets) Develop preliminary curb ramp layout in accordance with Chapter 12 of Iowa SUDAS Design Manual. Design ramp geometric configurations alternatives, identify surface requirements, review general horizontal curb opening, cross slopes, running slope, and identify sidewalk width and passing space within the corridor. Preliminary Streetscape Design (T Sheets) – Develop preliminary streetscape plans showing proposed paver locations and streetscape amenities. The scale of these plans will be 1” = 20’ Preliminary Cross Sections (W & X Sheets) This task consists of design and drafting associated with the assembly of detailed cross sections (25’ increments) to illustrate typical conditions, drainage designs, and non-typical conditions as needed for guidance during design, review, and quantity estimating purposesprevious repairs which include welding.
