K-4 - Sanitary Sewer System Design Proposal - Hickory Knoll - MSA

TASK 2: PROJECT SITE INFORMATION 1. Right-of-Way Research: utilize recorded survey documentation in project area to determine right- of-way locations.  Perform survey mapping of right-of-way along listed routes. 2. Contact Utility One Call: utilize marking and mapping provided by one-call agency to assess locations of existing private utilities in the area. 3. Topographic Survey: collect location and elevation data of existing features at the site for use as basis of design. The area to be collected is generally described as:  Entire right-of-way plus 10’ outside of the right of way along the proposed sanitary sewer route as well as along the alternate route as shown in the attached exhibit. 4. Boundary Survey: perform boundary survey on the parcels identified in the attached exhibit. 5. Easement Creation: Create up to four (4) permanent & temporary easement exhibits for the City’s use in acquiring easements along the intended route. 6. Utility Structure Survey: investigate existing utility structures along intended route to obtain field measured invert elevations, penetrating pipe information, and condition assessment. TASK 3: DESIGN – UTILITY DESIGN 1. Sanitary Sewer Design: Develop horizontal and vertical alignments for sanitary sewer. Determine structure, lateral, and connection locations. Prepare construction details. 2. Erosion Control Design: Prepare storm water pollution prevention plan to meet Iowa DNR NPDES General Permit No. 2 requirements. 3. Traffic Control Design: Prepare detour and traffic control plan. 4. Construction Cost Estimate: Develop a preliminary construction cost estimate based on preliminary plans. Develop an Engineers Estimate of Construction cost based on quantities computed from final plans. TASK4: PLAN PREPARATION, DRAFTING, & PROJECT MANUAL 1. Preliminary Plan Preparation (50% Review): Prepare preliminary plans showing topographic survey information, horizontal and vertical alignments of sanitary sewer, and typical construction details.  Intent of preliminary plan preparation is to give an idea of the proposed project. After preliminary review meeting, work under this subtask will be considered complete. 2. Final Plan Preparation: Prepare final plans based on 50% Final Plans and Owner’s minor feedback. 3. Project Manual: Prepare supplemental technical specifications (if needed), special procedures, bidding documents and construction contracting documents based on SUDAS specifications. TASK 5: UTILITY COORDINATION, AGENCY COORDINATION, & PERMITS 1. Utility Coordination and Communication  Inform private utility companies (gas, electric, and communications) of the project scope and timeline.  Note utility locations (as provided by utility companies and/or one-call locate) on the project plans.  Provide utility companies with final plans for the project. 2. Agency Coordination and Communication  Coordination with Iowa Department of DNR, Sewer Section. Assumed two (2) hours of coordination.
