Detailed tree survey and vertical elements of subsurface utilities are excluded for this survey. The land survey assumes no more than six (6) acres to be surveyed on one (1) parcel with a size of ten (10) acres. 1.6 Base Maps. Prepare base maps at a scale of 1” = 40’ using data from items 2, 3, and 4. Plot utilities on base maps. 1.7 65% Design. Prepare and submit preliminary construction cost estimates and 3 sets of construction plans (65% completion level). Submit draft specifications along with construction cost estimates. Design will be based on equipment specification/ cut sheets provided by City for sixty-four (64) chargers. Design assumption is based upon seven (7) Level 2 Charging Stations (7.2kW), forty-eight (48) DC dual-port chargers (40kW), eight (8) DCFC single-port chargers (60 kW) and eight (8) DCFC single-port chargers (120kW) at the Redwood City Public Works Corporation Yard in an existing parking lot. Site plan layout will be done in AutoCAD and will show the expected placement of EV chargers and related equipment along with existing structures and parking lot layout on the topographic land survey. • Qualified Chargers: Consultant will provide a short list of qualified EV chargers suitable for the project to the City. Following the required selection confirmation by the City, these specific chargers will be integrated into the construction drawings. • Single-Line Diagram (SLD): The preliminary SLD will be completed in AutoCAD printed to .pdf. The preliminary SLD will include electrical equipment size, wire and conduit schedules and the project’s required electrical load, proposed size and number of switchboards. Consultant will provide up to one (1) revision to the drawing, based on City review and comments. The electrical design will be based on standardized NEC requirements and equipment specifications provided by City. • Basis of 65% Design: EV charger equipment featured in the electrical design will be UL certified prior to the design and construction of the site. No additional disconnect switches will be required at the charger location. The utility fault current is assumed to be less than Short Circuit Current Rating (SCCR) of chargers and provided by the utility. The electrical design will not include future alternative energy provisions. The final Utility Design Package (UDP) deliverable will include utility design, specifications and scope of work as provided by the utility. Engineering will include up to two (2) sixty- (60) minute meetings with the City for CD65s. At the request of the Public Works Fleet Superintendent or their designee, Consultant will provide the following items not included in the design deliverable as an additional service based on the labor rates provided: relay settings files, regrading beyond the extent of impacted stalls and equipment pad, equipment platform designs, Right of Way (ROW) drawings, traffic control plans, impact studies, parking garages, ATTY/AGR.2025.050/Black & Veatch (EVSE Consulting and Engineering) (Page 13 of 23)
