a) Obtain copies of available aerial photos, and mapping covering the proposed route. b) Obtain available as -built street, water, sanitary sewer and storm drain plans from the OWNER. c) OWNER will provide City of San Marcos standard details. FNI will prepare a list of City of San Marcos details that are anticipated on the project and provide a list of City of Austin details needed to supplement the City's standard details. 4. Hydraulic Modeling: a) Obtain and Review Data: Obtain and review information from the OWNER including wastewater system GIS, survey and parcel data, the existing hydraulic model, and existing and projected flows for the project area. Obtain and review flow date from Texas State University. b) Construct a Sub -basin Model: Construct a hydraulic model to include existing wastewater lines within the sub -basin of the proposed replacement projects. FNI will utilize the OWNER's GIS to build the geometry and assign attribute data. Flows will be allocated to the model based on existing and projected flow data provided by the OWNER. c) Perform Hydraulic Analysis: Evaluate the sub -basin under existing and future flow conditions to determine appropriate sizing of replacement lines. Downstream impacts to the wastewater system will be identified. d) Review storm water design by Brown and GaEngineers: Coordinate with Brown and Gay to review storm water plans. 5. Develop Preliminary Engineering Report (PER): Prepare a Preliminary Engineering Report that includes: a) Determine project permitting and design requirements. b) An analysis of replacement methods including pipe bursting and open cut, and the recommended pipe sizes for each segment to be replaced based on the hydraulic model. c) Determine alignments including possible utility conflicts and easement acquisition. d) Schematic design of project using available aerial photography. e) Proposed construction phasing and sequencing for the project. f) Documentation of the wastewater model construction and hydraulic analysis. g) Preliminary opinion of probable construction cost (OPCC). FNI will provide a "Draft" engineering report for the OWNER to review. FNI will attend PER workshop with the OWNER and finalize the PER incorporating all necessary corrections and revisions resulting from the workshop. 6. Phase Deliverables: a) Monthly status reports. b) Draft PER: Two (2) hard copies and one (1) electronic copy in PDF format. c) Final PER: Two (2) hard copies and one (1) electronic copy in PDF format. d) One (1) electronic copy of hydraulic model. e) Furnish to the OWNER an updated written opinion of probable construction costs for the Project. B. 60% DESIGN PHASE: FNI shall provide professional services in this phase as follows: 1. Meetings: a) 60% Design Workshop: Meeting to discuss comments made on the 60% design submittal. Prepare meeting agenda and minutes. b) ivionthiy P-rogress iviecting: (i) additionai meeting to discuss the project progress.
