17060 P a g e | 3 Proposal for Storm Drain Pump Station Improvements Projects BRADFORD PUMP STATION The utilities locating subconsultant will use marking paint while on-site to show where the utilities are located. The utilities locating subconsultant will perform an on-site utility survey using RTK GPS or total station methods. Utility survey shall be on the California State Plane Zone III coordinate system and NAVD 88 vertical datum. Deliverables: Utility Map (ACAD & PDF) Task 2.3 – Gather and Review City SCADA and System Info The Consultant understands that the City contracts with TELSTAR Instruments (TELSTAR) for process control at its pump stations and will work with TELSTAR to understand the City’s existing Supervisory Control and Data Acquisition (SCADA) system and specific compatible equipment within the construction contract documents. Task 2.4 – Perform Topographic Surveying and Mapping The Consultant will provide a topographic survey for the Pump Station project site to develop a basis for the site improvements. The Consultant will develop a base map. The base map will include features that represent the underlying foundation information in which the project is based upon. The Consultant will prepare the topographic base mapping for the project. Surface features necessary for the plans (e.g. drain inlets, trees, water valves, etc.), utility information and base mapping approximately 20 feet beyond the limits of the project shall be included. Examples of base map information includes, but is not limited to, aerial imagery, street network information, elevation datasets, utilities locations, and boundaries such as parcel lines, and City limits. The Consultant recommends maintaining the features of the base map using both CAD drawings in ground coordinates, and a standard GIS projection such as California State Plane Zone 3 US Survey Feet to ensure that the information is compatible with other GIS platforms and applications. The boundary information developed in Task 2 will be incorporated into the base map. Office Survey The prime consultant’ survey office staff consists of a professional land surveyor (LS), a survey coordinator, and a survey office technician (LSIT). The Consultant will work to ensure that the field survey crew has the data needed to perform both accurate and precise topographic and boundary surveys. The Consultant will prepare the field surveyor’s daily planning information and site field survey instructions. These instructions ensure that the field crew has all the equipment, material, and access information to safely perform the field survey. The office survey staff is accessible to the survey crew via telephone, text, email, and Trimble “Access” software. The office survey staff will calculate the record right-of-way and boundary mapping information within an AutoCAD Civil 3D 2015 drawing. The collected field survey coordinate point information shall be downloaded and combined with the record right-of-way and boundary information by the prime consultant. Field Survey The prime consultant’s field survey crew consists of two highly experienced men who have completed and passed the union journeyman certifications. They are equipped with the latest in modern surveying equipment. This includes Trimble R8 GPS base and rover receivers, a Trimble S6 robotic total station, a digital level, plus standard supporting and safety. The field crew will establish the site survey coordinate control from NGS monuments based on the California Coordinate System, NAD 83, NAVD 88 coordinates utilizing GPS equipment. They will also search, recover, and tie record boundary and right-of-way monumentation. Finally, the prime consultant’s survey crew will interview with the survey office staff to discuss the project activities and field notes at the end of each day. ATTY/AGR.2021.257/Wood Rodgers, Inc.
