T.Y. Lin International (TYLI) was retained by the U.S. Army Reserve Center, through U.S. Army Corps of Engineers, Charleston District, to provide civil, structural, plumbing, and electrical engineering services and RFP development for the repair of docks, moorings, foundations, sheet pile seawalls, utilities, and vehicle staging areas at the U.S. Army Reserve Center’s in Morehead City, North Carolina. The pier upgrades were designed to accommodate the LCM/LCU 2000-series boats operated by 824th Transportation Company.

The existing waterside facility, designed in 1993, was originally intended to provide mooring and operational and maintenance support for the LCM/LCU craft of the 824th at this site. During construction, contaminated soils were found and work was halted until remediation was completed in 2004. However, construction was never completed or maintained. In 2011, the docking, fenders, and moorings were damaged by Hurricane Irene and the existing system continued to deteriorate.

The TYLI team was tasked with evaluating the existing reinforced concrete and timber piles, docks, fenders, seawalls, site, and utilities, and developing an RFP level design package for a design-build program to upgrade the facility. Geotechnical investigations were performed around the proposed dock locations to determine the existing soil parameters for evaluating the existing piles, designing new piles, and evaluating the existing vehicle loading and parking area. A mooring analysis was performed on the LCU 2000, a 174-foot-long by 42-foot-wide, 1,102-ton vessel, for the proposed mooring pile caps and dolphins.

The existing vehicle loading and parking area frequently flooded. Therefore, stripping of the existing site and installation of compacted fill over run of crusher (ROC) gravel pavement was proposed.

The existing LCU 1600 dock repairs proposed new timber dolphins and new wood framed deck with supporting concrete bents and piles for mooring. Two additional wood-framed docks and concrete pile caps/bents were added for access to and mooring of the LCU 2000 vessels.

RFP development design documents, including drawings and specifications, were developed for solicitation by the U.S. Army Corps of Engineers for the design-build project, along with an estimation of total construction costs.

Project Highlights:

  • TYLI was responsible for all reports, surveys, studies, master planning, project planning, design criteria, and preparation of drawings and specifications.
  • Mooring analysis and structural evaluation of existing concrete piles to be utilized for the new pier upgrades.
  • A Micro-Computer Aided Cost Estimating System (MCACS) was used to prepare estimates for RFP development.
