City of Santa Ana On -Call Engineering Services (RFP No. 23-030) Land Surveying Survey and base mapping of the project site will be prepared in US Customary English units by a California licensed Land Surveyor in accordance with City guidelines. Drawings will be submitted to the City in Microstation V8i CADD format. The horizontal datum will be North American Datum of 1983 (NAD 83) and the vertical datum will be North American Vertical Datum of 1988 (NAVD 88). All survey field notes will be on forms provided by the City, will be neatly completed in pencil, and will become the property of the City upon completion of the project. Informal Feld investigations including marking of removal areas may be required for some of the sidewalk, curb and gutter, and pavement replacement projects. Design Phase Surveying CWE has prepared survey mapping for topographic and boundary surveys. Our team can provide aerial, ground, or lidar topographic survey formats depending upon the project needs. Our boundary and right-of-way survey can provide easements, corner records, centerline ties, record of survey or any other boundary records needed. Our approach for survey starts with defining the survey needs (topography, boundary, culture (trees, poles, furniture, etc.) cross sections, encroachments, easements, or other needs. We will also determine if this can be a paper survey, such as collecting information and preparing a legal and plat for an easement, or if this will require field survey. The next item of work is research, determining horizontal and vertical datums, researching record maps for boundaries or right-of-way, collecting benchmark and monument information, collecting centerline ties, and other project reference information, such as as -built street or utility plans. Office calculations may be performed at this time to determine which benchmarks to utilize, where to set aerial targets for aerial survey, or monuments to check for control. When the research is completed, field crews will go to the project site to set targets, perform topographical survey, and/or perform boundary survey. Once the field crews have finished the field survey, the information goes back to the office to prepare the topographic survey, boundary survey, or other documentation as needed for the project. The final product (topographic map, record of survey, legal and plat, centerline ties, etc.) will be delivered to the City along with any electronic files or closure calculations. Construction Staking Our construction staking crew will review the construction plans and specifications and determine the location of proposed features such as pavement edges, curbs, and drainage structures. We will then use survey instruments to mark the proposed locations on the ground, ensuring that they are accurately positioned and properly aligned. The crew will place stakes or other markers to indicate the exact location and elevation of each feature to be constructed. Mapping Services Mapping services include legal description preparations and right-of-way studies. Our team can assist the City in their efforts to acquire property rights necessary to construct projects. We will prepare exhibits, including right of entry and right-of-way maps showing parcel boundaries and land acquisition boundaries. The exhibits will include measurement of permanent and temporary land acquisition area. -18- GE
