Client: City of Irwindale
WLG performed numerous mining pit surveys as part of an on-going effort to support the mining engineering group within the City of Irwindale. WLG performed research and mission planning and established aerial control for photogrammetric and bathymetric surveys including GPS / GNSS surveys and conventional surveying techniques. With the use of a dual frequency echo-sounder, we were able to accurately produce a lake bottom profile that was used to estimate underwater material extraction quantities. Irwindale-3 Topographic and boundary survey maps were prepared for 11 open mining pit locations within the City. WLG office personnel generated DTMs at each location and performed quantity / volume calculations for the City to verify the amount of material removed in a year-over-year comparison. The client also required detailed slope analysis in which our in-house staff created color-coded slope exhibit maps used to identify slope areas that were out of compliance with specified slope stability and safety requirements. As an additional service, we prepared finished surfaces for future mining pit reclamation used to calculate fill volumes that were required during mining closeout procedures. Digital survey data and mapping deliverables were also exported into a GIS deliverable format including shape files and geodatabase files to be incorporated into the City's GIS system.
Client: Layton Construction
This construction project included reviewing civil, architectural, and structural plans and generating RFIs for any discrepancies found with regards to the building layout. WLG survey crews established horizontal and vertical survey control throughout the site and provided multi-story building control lines and elevations for the construction of this six-story hospital building located in the City of Murrieta. WLG also prepared various as-built surveys to check concrete floor deflections and structural steel.
Client: City of Rancho Cucamonga
This two-mile drainage rehabilitation project along Hellman Avenue included reviewing civil and structural plans with regards to the design, establishing horizontal and vertical survey control throughout the project, monumentation of street centerlines, and providing control lines and elevations for the construction of the improvements. WLG also prepared various as-built surveys to verify design along the route and our field engineers prepared additional designs to fit field conditions.
Client: Jacobs / BNSF Railroad
This construction project included reviewing civil, architectural, and structural plans and generating RFIs for any discrepancies found with regards to the bridge layout. WLG survey crews established horizontal and vertical survey control throughout the site and provided control lines and elevations for the construction of the overpass, located in the City of Vernon. WLG also prepared various as-built surveys to check concrete and structure deflections.
