Specifications include, but are not limited to: The San Joaquin County Department of Public Works (SJCDPW) is soliciting qualifications from land surveying (LS) firms. These firms are being sought to offer professional and technical services catering to various land surveying needs on an as-needed basis, supporting diverse design and construction projects across San Joaquin County. Professional services must be conducted under the supervision of a Licensed Land Surveyor registered in California. These services may involve topographic and right-of-way surveys for design initiatives, as well as staking and project layout for construction endeavors. Design and construction projects encompass a variety of undertakings, including resurfacing, roadway reconstruction and widening, bridge replacement, scour mitigation (involving channel surveying), and embankment repairs (for slide slopes). SJCDPW will establish a list of two or three LS consulting firms. Each selected firm will provide LS services on an “on-call” basis, and a Purchase Agreement will be executed with each CONSULTANT. The “on-call” list will be in effect for a two-year period with the option of SJCDPW to extend the period for one additional year. A CONSULTANT has the option of using subconsultants, with the approval of the County, for the following: • 3D-Modeling of collected surveying data • Traffic control to facilitate the survey work
