EBA provided construction and materials quality control management and inspection, as well as on-site and off-site materials testing services as the quality control (QC) engineer for this design-build contract awarded to Intercounty Connector Constructors (IC3), a joint venture.
EBA created the Construction QC Plan to outline QC procedures, coordinate inspections with IC3 contractors and fabricators, ensure that testing and sampling frequencies met or exceeded required thresholds, coordinate and assemble all QC documents to ensure an effective closeout, and certify that work and material quality met contract requirements.
EBA documented and inspected work performed by IC3 contractors for a wide range of construction activities, including erosion and sediment controls, stormwater management facilities, bridges, box culverts, retaining walls, noise walls, roadway excavation and embankments, aggregate base, paving, pavement markings, roadway lighting, electronic toll collection, intelligent transportation systems, and landscaping.
Our materials testing services were unique as we provided QC material inspection, sampling and testing, and source of supply approvals for the IC3, a function usually performed by the State Highway Administration. Off-site services included inspecting materials provided by fabricators, precast concrete products, and various coatings. Our on-site services included verifying that materials were from approved supply sources, sampling and transport of various materials for lab testing, and on-site materials testing.
