TASK 2 — Create GIS Dataset for Underground Utilities This task includes researching and reviewing available record drawings and creating GIS features to represent underground facilities in the Port area. Subtask 2.1 — Research /Review Record Drawings and Field Reconnaissance The City's staff will conduct site visit, as necessary, to the Port's office to research and review hard -copy record drawings of the Port's underground utilities. Any drawings with relevant information will be temporarily borrowed by the City for use in subsequent tasks. If the original drawings cannot be borrowed, then a copy will be requested. Minimal field reconnaissance will be conducted to verify the surface features of existing utilities and to record drawing information accuracy. The City estimates approximately eight (8) hours of field work for verification. The current scope does not include any surveying to determine the depth of the existing utilities or potholing to confirm the utility locations. The GIS utility layers will be developed solely from the use of record drawings. Subtask 2.2 — Develop Data Model Design for New Utilities The City will develop a data model design to be used for incorporating information into the GIS database for new utilities. The City's staff will use the existing data model structure for utility systems that the City already has in its GIS database (i.e. potable water, recycled water, sanitary sewer, and storm drain). The City will design an appropriate data model to support the Port's need for other utilities (i.e. gas and electric) for incorporation into GIS database. The City staff will discuss the new utility layers with the Port for inclusion in GIS. Subtask 2.3 — Digitize Record Drawing Information Using record drawings gathered in Subtask 2.1, the City's staff will create GIS features (points, lines, and polygons) to represent the underground utilities in the Port area. All utilities will be drawn as accurate relative to existing locations using the information from the record drawings. Subtask 2.4 —Conduct Data Entry of Attributes Using record drawings gathered in Task 3.1, the City's staff will transfer descriptive attributes about the underground utilities to the GIS dataset. These attributes will include such information as pipe diameter, material, date of construction, rim elevation, invert elevations, valve types, and valve sizes. The City's staff will work with the Port to determine which attributes to capture prior to commencing work. Subtask 2.5 — Establish Workflows To ensure the future accuracy of the Port's GIS data, the City's staff will help establish workflows for data maintenance, either by Port personnel or the City's GIS staff. Additional maintenance agreement will be created to support his work.
