Sinkholes can be very dangerous and often happen without warning. Here are five things you should know about sinkholes.
Shield Engineering was contracted by a major Class I Railroad Company to develop an engineering design for an equipment wash bay structure. This project was developed to comply with the Commonwealth of Virginia General VPDES Permit of Storm Water Associated with Industrial Activity (9VAC25-151), which requires the implementation of best management practices. Such practices prohibit all cleaning operations to be indoors, ensures that all wash water drains to proper collection systems, and that collected wash water is properly treated and disposed of per State and Federal requirements.
Shield’s scope of work for the New Equipment Wash Bay facility included civil site design and layout planning, geotechnical investigations, structural foundation design, bid solicitation assistance and construction management, construction materials testing, and inspections. Key project features include:
Shield’s innovative approach for design and engineering allowed the Owner to realize a successful project that was previously hindered due to design challenges. Unforeseen environmental conditions were encountered during excavation. Approximately 500 CY of petroleum-impacted soils were excavated and managed using field screening methods.
Modifying the original soil disposal plan for environmental considerations reduced Contractor costs by over $5,000. The Owner took occupancy of a new facility that not only incorporates specific Rail Yard needs and environmental regulatory requirements of the Commonwealth of Virginia, but also benefited from proactive construction management services which resulted in a total savings of almost $23,000 on an original $350,000 project.
