Winter Simulation Conference - Integration of construction and traffic engineering in simulating pipe-jacking operations in urban Areas
Proceedings of the 2011 Winter Simulation Conference (WSC), 2011Co-Authors: Ming Lu, Chi-sun PoonAbstract:Construction simulation and traffic simulation are complementary to successful planning of microtunneling and pipe-jacking operations in urban Areas. With increasing concerns on sustainable development, it is imperative to integrate construction engineering and traffic engineering in simulation modeling in order to plan for efficient site operations while reducing the impact of construction upon traffic. In this research, we demonstrate a "larger system simulation" approach to effectively plan pipe-jacking operations in urban Areas in considerations of (1) truck delivery routes and timing; (2) sizing and location of temporary Laydown Area on site; (3) traffic lane closure distance; and (4) working hours scheduling, aimed at minimizing the negative impact of construction on traffic. Our research goal is to deliver a temporary traffic arrangement plan along with an efficient site operations plan, thus keeping a balance between construction productivity and traffic mobility. A case study is given based on a pipe-jacking site in the urban Area of Hong Kong.

Remaining Sites Verification Package for the 100-B-1 Surface Chemical and Solid Waste Dumping Area, Waste Site Reclassification Form 2006-003
2006Co-Authors: R. A. CarlsonAbstract:The 100-B-1 waste site was a dumping site that was divided into two Areas. One Area was used as a Laydown Area for construction materials, and the other Area was used as a chemical dumping Area. The 100-B-1 Surface Chemical and Solid Waste Dumping Area site meets the remedial action objectives specified in the Remaining Sites ROD. The results demonstrate that residual contaminant concentrations support future unrestricted land uses that can be represented by a rural-residential scenario. The results also demonstrate that residual contaminant concentrations are protective of groundwater and the Columbia River.

remaining sites verification package for the 600 233 waste site vertical pipe near 100 b electrical Laydown Area waste site reclassification form 2005 041
2005Co-Authors: R. A. CarlsonAbstract:The 600-233 waste site consisted of three small-diameter pipelines within the 600-232 waste site, including previously unknown diesel fuel supply lines discovered during site remediation. The 600-233 waste site has been remediated to achieve the remedial action objectives specified in the Remaining Sites ROD. The results of verification sampling show that residual contaminant concentrations do not preclude any future uses and allow for unrestricted use of shallow zone soils. The results also demonstrate that residual contaminant concentrations are protective of groundwater and the Columbia River.

South Gate Complex Planning and Design - Port of Palm Beach, Riviera Beach, Florida
Ports 2007, 2007Co-Authors: J Casey Long, Thomas J Lundeen, David W MockAbstract:The Port of Palm Beach is a 153 acre niche port located on the Southeast coast of Florida, approximately 60 miles North of Miami. Over the past decade, the Port of Palm Beach has transformed to a modern Port able to meet the planned needs of its tenants and implement their 1995 Master Plan. Today, due to efficient land use, it has one of the highest container throughputs per acre in the country. The Port continues to grow in throughput at a rapid pace and it is imperative that they adapt their current and restricted land to meet the expanding demands. In 2005, the Port developed a 2005 – 2015 Master Plan that established nearly $150 million in Capital Improvements to expand the Port's operations by more efficiently using the existing lands and proposing Southward expansion into new land. One project within the 2005 Master Plan is the creation of a South Gate Facility which includes: Demolition of an existing 160,000 SF office/retail building; Construction of a 60,000 SF Warehouse and associated Security Offices; Construction of Access Road Improvements; Construction of a New Multi-Lane Gate Facility; and Construction of a 5.5 acres of cargo Laydown Area. The South Gate project is budgeted at $16 million for planning, design, and construction. At completion, this project will open up/develop 2 acres of waterfront by consolidating the warehouses spread throughout the Port as well as create nearly 6 acres of additional cargo lay-down space for expanded Port business. This project is expected to be the cornerstone project to start the remainder of the 2005 Master Plan projects including a future tie-in to planned future state highway improvements. It is expected that the South Gate Facility will be accomplished while maintaining uninterrupted business operations. Through tenant partnering, aggressive planning and decisions, this project is expected to be completed at the end of 2007. This paper outlines the process of planning, security considerations and requirements, the functional layout of the facility and the construction phasing processes to be used in order to maintain business flow during construction.

Supplement analysis for Greenville Gate access to Kirschbaum Field at Lawrence Livermore National Laboratory
1997Co-Authors: SafetyAbstract:The National Ignition Facility (NIF) Program proposes to provide additional access to the Kirschbaum Field construction Laydown Area. This additional access would alleviate traffic congestion at the East Gate entrance to Lawrence Livermore National Laboratory (LLNL) from Greenville Road during periods of heavy construction for the NIF. The new access would be located along the northeastern boundary of LLNL, about 305 m (1,000 ft) north of the East Gate entrance. The access road would extend from Greenville Road to the Kirschbaum Field construction Laydown Area and would traverse an existing storm water drainage channel. Two culverts, side by side, and a compacted road base would be installed across the channel. The security fence that runs parallel to Greenville Road would be modified to accommodate this new entrance and a vehicle gate would be installed at the entrance of Kirschbaum Field. The exiting shoulder along Greenville Road would be converted into a new turn lane for trucks entering the new gate. This analysis evaluates the impacts of constructing the Kirschbaum Field bridge and access gate at a different location than was analyzed in the NIF Project specific Analysis in the Final Programmatic environmental Impact Statement for Stockpile Stewardship and Management (SS and M PEIS) published in September 1996 (DOE/EIS-0236) and the Record of Decision published on December 19, 1996. Issues of concern addressed in this supplement analysis include potential impacts to wetlands downstream of the access bridge, potential impacts to the California red-legged frog (Rana aurora draytonii) listed as threatened on the federal listing pursuant to the Endangered Species Act of 1974, and potential impacts on the 100-yr floodplain along the Arroyo Las Positas.
