Task 2 - Data Collection
Psomas will collect data and perform research to identify and confirm existing improvements and constraints, and to gather background information from available record drawings on streets that are within the project limits. No independent utility coordination and/or outreach is assumed as part of this scope. Psomas will participate in a field review with the City if requested to confirm existing conditions and to identify physical features that may be constraints for the project.
Task 2 Deliverables:
Data Collection, and record drawings collected
Field Notes
Task 3 - Topographic Survey/Right-of-Way Mapping
Within the project limits, Psomas will:
Establish survey control.
Locate enough monuments to establish right-of-way from available recorded data for the residential tract.
Prepare Aerial Mapping for the residential tract.
Topographic survey, 34 curb returns within the residential tract.
Survey Control: Horizontal and Vertical project control will be established for the project area. The horizontal control will be tied to California State Plan Coordinates, NAD83, Zone V.
Vertical control will be tied to the City of Rialto Benchmark network.
Research and Base Mapping: Cadastral research within City of Rialto and the County of San Bernardino will be performed to find existing centerline and right of way line to support the establishment of the Land Net Base Map.
Land Net Base Map: Psomas will locate enough monuments to prepare a Land Net Base Map prepared from available record information. Psomas will establish the existing centerline and right of way lines within the area as shown in the above exhibit.
Topographic Surveys: Conventional ground surveys will be performed on 34 ADA ramps.
Limits of the surveys will extend beyond 25’ from the BC and EC of the curb returns and will extend a minimum of 10 feet into the roadways.
Aerial Mapping: Topographic mapping will be provided from aerial photogrammetry. topography will be compiled at a scale of 1"=40' with 1' interval contours.
Aerotriangulation will be performed and analyzed prior to the start of the map collection. Map collection will be performed on Hexagon ImageStation softcopy photogrammetric workstations. All resulting topographic and planimetric mapping will conform to typical 1"= 40' scale mapping, capturing all discernable planimetric and topographic features for roadway, utility, and cultural items. A DTM, consisting of breaklines and mass points, will supplement select planimetric features to create the final surface model and the creation of the 1' contours. Completed topographic mapping will be delivered as .DWG files with surface and exported XML file.
Task 3 Deliverables:
Aerial Mapping CADD
AutoCAD Civil3D DWG
Stamped and Signed PDF of the Survey
Task 4 - Street Improvement Plans
Psomas will prepare a complete set of Improvement Plans for the Boyd Elementary SRTS project. Plans will be submitted to the City at the 65%, 90%, and 100% submittal stages.

Note that the professional fees established for the various types of plans are based on the following:
All plan types will be prepared in City of Rialto plan format. This scope of work assumes that roadway work within the project area will consist of 2” grind and cap. No custom pavement design will be included in the scope. A total of 34 existing ramps are found within the project limits, none of which appear to be ADA compliant. Each will be assessed and upgraded per current ADA standards. For budgeting purposes, standard curb ramps per City of Rialto Standard Plan SC-215 will be called out at each location. Detailed curb ramp design will not be included, and elevations will not be specified on the plans. Topographic survey on curb ramp locations will be used to determine the proper type/case to implement at each location. Existing utilities will be shown on the plans per information obtained through existing as-built/record drawings as provided by the utility companies, the City, and field survey data. Potholing and/or ground penetrating radar (GPR) of existing utilities is explicitly excluded from this Scope of Work.
The Scope of Work does not include drainage design services. Erosion Control Plans are excluded.
Task 4 Deliverables:
Street Improvement Plans (65%, 90%, and 100% submittals) with signing-striping integrated on the same layout sheets
Task 5 - Cost Estimates
Psomas will develop quantities and will prepare an itemized engineer’s estimate for the 65% submittal package. Unit costs will be determined by reviewing similar recent project bid summaries and current Caltrans Contract Cost Data book. The estimate will be updated at each subsequent submittal stage.
Task 5 Deliverables:
Engineer’s Cost Estimate (65%, 90%, and 100% submittals)
Task 6 - Technical Specifications
Psomas will prepare technical specifications following the 2021 Standard Specifications for Public Works Construction (the Greenbook). It is assumed that the City will provide their “front end” boiler plate in Microsoft Word, to which the technical specifications will be inserted.
Psomas will submit the technical specifications with the 90% and 100% submittal packages.
Task 6 Deliverables:
Technical Specifications (90% and 100% submittals)
ASSUMPTIONS/EXCLUSIONS
Due to the nature of the proposed improvements, a geotechnical report is assumed to not be required and is therefore excluded.
It is assumed that the City will secure all right of way and/or rights of entry needed for improvements adjacent to private property, if applicable. Legal descriptions and plats are assumed not required and are therefore excluded. Any encroachment permits and other permit fees, if applicable, will be paid for by the City.
Stage Construction/Traffic Handling Plans will not be required and are excluded. Hydrology and hydraulic analysis is assumed not needed and is excluded. The proposed improvements are not anticipated to impact existing drainage patterns.
Therefore, drainage analysis and design are excluded.
Permanent water quality BMPs are assumed not required and are excluded. Planting/Irrigation plans will not be required and are excluded. Bid phase and construction support services are excluded but can be provided as additional upon request.
