Work flow analysis
Lin & Associates, Inc.'s (L&A) land surveying group has been providing quality service since 1992, working on major projects throughout the state of Washington for clients such as WSDOT, Sound Transit, the City of Seattle, and King County. Most notable has been L&A’s continued involvement with the Sound Transit Link Light Rail Project for the last 16 years. Lin & Associate's familiarity with the City of Seattle’s standards and past experience working on federally funded projects for the City of Seattle, WSDOT, and Sound Transit has increased their efficiency and has proven to be a valuable asset to clients. Services offered include: GPS, Topo Surveys, ALTA Surveys, Monument Control Surveys, Boundary Surveys, Cadastral Surveys, Monitoring Surveys, Base Mapping, Right-of-Way, Deed Takes, Legal Descriptions, Construction Staking, Lot Boundary Adjustments, Digital Terrain Models, Easements, CAD and Project Research.
Right of Way Engineering
Lin & Associates, Inc. (L&A) creates project base maps and easement exhibits for alignments, including surveying and locating public and private utility infrastructure for utility mapping. L&A also provides topographic surveys of surface features in full detail from intersections, including building lines/corners, traffic striping and pavement markings, as well as location of traffic signal equipment, signal heads, overhead utilities & supports, and overhead trolley wires & supports. L&A also works with designers to pick up survey requests as needed. Services also included underground utility location and potholing surveying.
L&A provides construction management services to local agencies, including construction consulting and inspection. L&A has the ability to provide services during the design phase in the form of constructability reviews, coordination and scheduling, as well as during the construction phase in the form of general construction management and inspections. L&A has a history of identifying and resolving potential difficulties during the design phase, providing quick, effective solutions during the construction phase when changes in the field arise, and also serving as the owner’s representative out in the field.
3D LIDAR Scanning
Light Detection and Ranging (LiDAR) is an innovative surveying solution that incorporates LiDAR sensors, cameras and position/navigation equipment to collect point data quickly and accurately. L&A owns and operates the Leica ScanStation10, P20 and P40 High-Definition Laser Scanners which gives us the ability to collect large amounts of data in a short amount of time with a high degree of accuracy and detail. LiDAR scans can be quickly converted into topographical maps or 3D modeling of as-built structures to support further development.
Drone photogrammetry offers a fast, cost-effective and often safer method for Lin & Associates to collect aerial imagery and scan points required for accurate mapping, verification, and site plans. Photogrammetry transforms 2D images into 3D models, allowing a 3-dimensional view, which helps to interpret the surveyed area in more depth. With our licensed drone pilot, L&A has the ability to establish scan points around the building or area in question so that there is a clear line of sight to the columns which were surveyed.
