Feasibility Of Implementing A Construction Project In An International Country, Kristina Poliseri Jun 2024

Feasibility Of Implementing A Construction Project In An International Country, Kristina Poliseri

Construction Management

This paper examines the execution of an international service project involving the construction of a complex system. It explores three distinct approaches assuming a fully designed system: building the system in the U.S. and shipping it internationally, having system pieces constructed entirely in the destination country prior to arrival for assembly, and developing a prototype in the U.S. followed by the construction of a full-scale system in the international country. Each method presents unique advantages and challenges. Building in the U.S. ensures high quality, advanced technology, and meeting tolerances, however, leads to significant fees, shipping costs, and logistical complications. Constructing …

Evaluation Of Ndot’S Sediment Barrier Practices Using Performance Data, Michael A. Perez, Wesley N. Donald, J. Blake Whitman, Brian G. Roche

Nebraska Department of Transportation: Research Reports

To protect waterways adjacent to construction projects with disturbed land, a 50 ft (15 m) vegetated buffer or equivalent sediment controls are required. However, there is little guidance on the effectiveness of vegetated buffers in removing sediment or how sediment barriers can aid shorter buffers or replace buffers. A modeling methodology was developed and used to determine the performance of 11,664 50 ft (15 m) vegetated buffer configurations with Nebraska conditions; sediment capture averaged 92.6% and ranged from 18.5% to 99.5%. To determine the performance of Nebraska Department of Transportation standard and modified sediment barrier installations, a large-scale testing methodology …
