LKB was retained by Westchester County Department of Public Works to provide design, construction support services, as well as construction inspection services for the replacement or repair of 34 overhead span and cantilever sign structures located on various County roads. The project included the installation of 10 new cantilever sign structures, 7 new span structures, and 2 new mast arm structures. In addition, 10 structures were repaired, 5 cantilever sign structures were changed to ground mounted structures, and 2 were removed.
The preliminary design included field inspection, non-destructive testing, survey and borings at the locations of the sign structures to be replaced. A report was prepared documenting the inspection findings, presenting alternatives and recommendations along with preliminary estimated construction costs. The final design included sizing and layout of new sign panels, new sign structures and foundations and guiderail. Work Zone Traffic Control (WZTC) plans were developed for each of the sign locations.
LKB’s construction support services during the construction phase included review and approval of detailed shop drawings, catalog cuts, and miscellaneous submittals for compliance with contract documents; review and responses to RFI’s (Request for Information) and Change Order Requests; and attendance of progress and project meetings, as necessary.
LKB also provided construction inspection for this project, which included the complete removal of 7 Tri-truss span structures and replacement with 7 Quad truss span structures, removal and replacement of 10 cantilever sign structures, and replacement of 2 mast arm sign structures along with various other ground mounted and sign panel replacements on existing structures.
Construction inspection services included overseeing all of the contractor’s operations such as demolition, drilling of footing shafts, placement of footing reinforcement and anchor bolts, placement of K-crete and concrete for footings, erection of sign structures and sign panels, etc., along with coordinating with the contractor on their construction schedule, fabrication process and payments, and coordinating all RFI’s, shop drawings, catalog cut submissions and reviews with the contractor, design team and County.
The project is currently in the final close-out phase.
