Utility Contractor 33 dustries. Key suppliers on the project were Submar and United Rentals. All subcontractors were hand select- ed and invaluable to the overall project success. Each subcontractor displayed extensive knowledge in their respective trades and genuinely cared about the fi- nal result of the work. Throughout the duration of the project, Barnard main- tained open communication, which resulted in effective scheduling and a project completed ahead of schedule. As the GC, Barnard had the respon- sibility of selecting safe, reliable and affordable subcontractors and suppli- ers. Each subcontractor selected on this project had developed a quality rela- tionship with Barnard on previous proj- ects and exhibited quality performance. Barnard takes pride in working along- side subcontractors and incorporating them into the project team. Prior to per- forming any work, Barnard provided all subcontractors with a project-specific orientation and had them attend PG&E Veriforce onboard training. This effort brought everyone together to work to- ward the common goal of improving the community's safety and making PG&E one of the safest and most reli- able utilities in the nation. One of most successful attributes of the R-407 Program was having it con- ducted with zero safety incidents. Bar- nard places a special emphasis on every aspect of safety and requires the same from all subcontractors. The commit- ment to safety from all of the subcon- tractors on this project was exemplary. Milbar Hydro-Test Inc. conducted the 8-hour strength test and assisted Barnard crews in the dewatering and drying operations. Cal Inc. completed the removal of the asbestos pipe coating that was found to be 2% on L-400. Atlas Tree Surgery Inc. removed over 400 almond trees within the PG&E ROW and mulched the trees onsite with a tub grinder. They then removed and disposed of the mulched material. PSC Environmental Services LLC provided precautionary emergency spill response vacuum trucks during the gas clearance. Guida Surveying Inc. per- formed all field surveys, and then com- piled and produced the final as-built package for all newly installed piping. Larry Jenkins Trucking Inc. provided the trucking of aggregates and sand to the main isolation point at Buckeye Sta- tion. Nordic Industries provided the RSP and trucking services required for the streambed remediation. Submar Inc. provided the con- crete mats and handling frame for the streambed stabilization. United Rentals Inc. provided the trench shields, trench boxes and speed shores that Barnard used during the excavation process. These suppliers were able to meet all re- quested timelines for material delivery and provided quality products. Since becoming a PG&E Alliance Partner in 2013, Barnard has com- pleted hundreds of projects throughout California. The R-407 Program is a true testament of PG&E and Barnard's con- tinued commitment to executing suc- cessful transmission line upgrades that improve the safety of communities. Barnard recognized early on that Pe- troleum Creek was an environmentally sensitive area requiring the utmost at- tention. The team held numerous site walks and developed a plan to execute work with minimal disturbance to Pe- troleum Creek. Barnard completed the project with zero environmental com- pliance issues or notice of violations, and developed a great rapport with en- vironmental governing agencies. Barnard also recognized that con- struction would take place during the almond harvest, which led to regular correspondence with almond orchard owners. From these discussions, Bar- nard established alternate access routes to avoid any impacts on the harvest. Barnard greatly increased the level of safety for the community by rerouting L-400 to an adequate depth. While in- stalling L-400, Barnard also reinforced the streambanks to ensure that water in Petroleum Creek flows within its es- tablished boundaries, preventing flood- ing in surrounding areas. The project team's due diligence in the planning stage set the foundation for a successful and beneficial project.
