NNS I ) <br /> CIVIL/SITE DEVELOPMENT DESIGN <br /> Our engineers are very proficient in site development services, including grading, access roads,parking lots, <br /> water and wastewater facilities, fencing, etc. The NELHA Airport Connector Roads and Other Roads on Host <br /> Park and HART On-Call Construction Contractor projects are examples of our capabilities in this area. <br /> ROADWAY REHABILITATION DESIGN <br /> WSP has been contracted by the City and County of Honolulu (City), Department of Design and Construction <br /> (DDC) to design roadway rehabilitation projects for various streets in Honolulu. Design responsibilities <br /> included field reconnaissance of existing conditions for roadway, sidewalk, curb and gutter, and drainage <br /> facilities;preparation of plans and specifications, and coordination with the City's Department of Facility <br /> Maintenance on proposed remedial work; coordination with the City's Department of Transportation <br /> Services on replacement and/or modifications of existing pavement markings; and preparation of bid <br /> documents and addenda for project construction contracts. Responsibilities during construction included <br /> design support services for preparation of Post Contract Documents (PCD), and review of contractor <br /> submittals and requests for information(RFIs). <br /> SEWER DESIGN <br /> We are experienced in sewer rehabilitation work throughout various communities on the island of Oahu.The <br /> work involved rehabilitating small mainline sewer systems using the cured-in-place pipe method as well as <br /> replacing deteriorated sections of sewer line.Also included in this work was the rehabilitation of existing <br /> sewer manholes. <br /> WSP is experienced in the conversion of Large Capacity Cesspools (LCC) and the permitting as required by <br /> EPA and the Department of Health.We have performed Cesspool Conversion studies for the USACE at the <br /> Pohakuloa Training Area and Kilauea Military Camp (KMC) on the island of Hawaii. For KMC,we designed 18 <br /> Individual Water Systems (IWS), converting 16 cesspools, abandoning two cesspools and obtaining all <br /> necessary permits.Permits for the conversion work included obtaining Approval to Construct, the IWS <br /> Variance, Construction Inspection and Approval to Use letters from the Department of Health(DOH), <br /> Wastewater Branch; permit to operate and a permit to abandon from DOH Safe Drinking Water Branch; and a <br /> NPDES permit from DOH Clean Water Branch. <br /> TRENCHLESS TECHNOLOGY <br /> The Honolulu office staff has incorporated trenchless technology design in the H-3 Roadway Finish Unit II <br /> project in Aiea where micro-tunneling design solutions were used for waterline installation under the heavily <br /> traveled H-1 Freeway to minimize disruption to traffic. <br /> Our available technical resources include individuals at the forefront of the advance of trenchless technology. <br /> Several are members of the North American Society of Trenchless Technology(NASTY) and sit on various <br /> committees.We offer services including feasibility studies; cost comparisons of micro-tunneling vs. <br /> conventional trenching; preparation of plans and specifications; and development of initial support systems <br /> for larger tunnels. <br />
