Surveys and Mapping. F.1. The Company shall provide as-built survey personnel during construction to document actual placement of all underground and above-ground facilities.
Surveys and Mapping. Task 1.3.1.1 – Project Survey Control Project mapping will begin immediately upon notice to proceed. Under the direction of DHA, SHN will perform the necessary research of the properties encompassed by and adjoining the project. The basis for the topographic and boundary related surveys will be State Plane Coordinate System NAD 83 horizontally and NAVD 88 vertically. Project surveys will be accomplished using only field survey techniques and will adhere to Caltrans survey manual for standards of accuracy, Caltrans survey manual for field procedures and the Caltrans safety manual for safe surveying practices. SHN survey staff will perform existing conditions field surveys and prepare project base maps for the project site to include; contour interval of 1 foot, sufficient strip mapping of the existing roadways to verify the proposed alignments, sufficient creek channel length and detail to evaluate hydraulics, geomorphology and placement of bridge, all surface evidence of existing utilities and structures within the project limits that may affect the project, height of overhead utility lines that may conflict with the project, trees greater than 4” in diameter at breast height, ordinary high-water marks, striping and signage, driveway cuts, sidewalks, parking areas and fences SHN’s surveyors will utilize AutoCAD Civil 3D version 2010 to compile the existing conditions data and establish an existing ground surface for use in the design process.
Surveys and Mapping. Bear/ESE This task will include researching Inyo County and BEAR Engineering records for information applicable to the project. An aerial control survey to establish horizontal and vertical control will be performed using GPS- RTK survey methods using an NGS Opus solution of GPS receiver data. GPS-RTK survey shall include ground control for each drone flight and fill-in measurements of existing improvements as needed. Survey control shall be in CCS (NAD 83) Zone IV, US Feet using Geoid 2012. A base map including monumentation, measured improvements and topographic contours will be prepared. Deliverables: Base maps in AutoCAD Civil 3D 2021 format (also see Task 5 deliverables), images, notes Task 4 - Environmental Studies and Documentation – Geode The environmental task includes the following activities. Eastern Sierra Engineering 12 Reno ❖ Zephyr Cove ❖ Bishop ❖ Mammoth Lakes Proposal for Environmental and Engineering Services in Support of HSIP Onion Valley Guardrail Project Anticipated Activities (these activities are included in the proposal and cost): Environmental Project Description Upon project initiation and working in conjunction with ESE and county staff, Geōde will create a concise project description that describes the nature and scope of the project. The project description will address the type of improvements, level of disturbance, and type of equipment to be used as well as an implementation schedule. Geōde will liaise with the United States Forest Service early in the project initiation process to ensure the correct jurisdictional agencies are engaged in the project’s environmental documentation and analysis. CEQA Categorical Exemption (CE) Geōde will complete the environmental review of the anticipated CEQA documentation. This documentation includes, but is not limited to: field, literature and electronic database reviews; and technical analysis. Technical studies are not anticipated, as the project involves negligible or no expansion of use. As the shoulders along Onion Valley Road have been previously disturbed from grading and driving, the installation of the guardrail is anticipated to be exempt under a CEQA as an existing facility. ECR/MMRP Geōde will ensure compliance with any jurisdictional permits and project avoidance, minimization, and mitigation measures using an Environmental Commitments Record (ECR) or a Mitigation Monitoring and Reporting Plan (MMRP). The ECR/MMRP is a matrix noting the necessary environmental provisions, wi...
Surveys and Mapping. Wood Xxxxxxx will perform boundary surveys to support the location of a proposed well site on the property identified in Sacramento County as APN 150‐0011‐044. The proposed well site is to be located at the southeast corner of existing IWTP property and be approximately 150’ by 150’. Our resolution will be based on the location of record monuments and use of record information such as, record maps, deeds, and title documentation. No additional monuments will be set. We will analyze calculated and measured distances and compare them to record data. Title Reports for APN’s 150‐0011‐043 & 150‐0011‐044 should be provided to support the boundary and verify current title information. Wood Xxxxxxx will also retain a firm to help negotiate the purchase of the required additional parcel. The level of this effort will be dictated on the owner’s wiliness to sell and our cost estimate should be consider an approximation. Deliverable(s): Base mapping of the Project site & Boundary Surveys and Mapping

The level of this effort will be dictated on the owner’s wiliness to sell and our cost estimate should be consider an approximation. Deliverable(s): Base mapping of the Project site & Boundary Surveys and Mapping Task 3.5 – Preliminary Site Layout Site configuration will include providing a site layout and space planning for equipment and provisions for treatment options in the event that future changes in regulations or water quality require the addition of treatment facilities. Xxxx Xxxxxxx will prepare alternate layouts for review and consideration. These layouts will look at the overall site as well as the existing building layout and location of pertinent equipment for access and maintenance. Our staff will evaluate location of utilities to tie into including electrical power, water and sewer in order to strategically locate facilities. The purpose of this task is to analyze efficient site layout to keep a compact orientation of facilities to one another and to preserve space for other uses. Reduced maintenance of facilities can be achieved with careful planning to reduce the length of chemical lines, locating transformers close to available power, providing shade or taking advantage of existing shade, reducing the amount of equipment and fit for purpose for the application.
Surveys and Mapping. Mapping services to be provided may consist of, but are not limited to, the following: topographic survey and horizontal/vertical control; orthomosaic and aerial photography (both new flights and historical photo searches); boundary surveys and land owner/property searches, monitoring/baseline surveys; utility location surveys, hydrographic surveys, bathometric surveys; and use of Geographic Information System (GIS). Survey and mapping deliverables shall be MicroStation compatible output or otherwise compatible with client’s software. GIS deliverables shall be in accordance with the Tri-Service GIS/Spatial Data Standards. Geospatial data for DOD customers must comply with Executive Order 12906. This requirement is implemented through ER 11101-8156. The Contractor may be required to generate metadata on any project completed for DOD. The Contractor should be familiar with the Federal Geographic Data Committee Content Standard for Digital Geospatial Data. If the generation of metadata is required, the specific requirements will be included in the individual task orders.
