Service: Remedial Construction
Project: NAVFAC SE SWMU 24 and Pier Charlie Debris Removal
Client: U.S. Navy NAVFAC SE
Site Location: Naval Weapons Station Charleston, SC
Period of Performance: July – November 2008

H&S performed surgical excavation and disposal of 4,000 tons of RCRA hazardous and non-hazardous construction debris at SWMU 24 and demolished and disposed of 12 creosote laden bumper boxes at the Naval Weapons Station Charleston, SC. Debris was present in a densely overgrown forested area requiring removal of dense vegetation while avoiding damage to trees greater than 6 inches in diameter.

Upon receipt of NTP we prepared planning documents including a health and safety plan, work plan, CPM schedule, waste management plan, and a schedule of values for tracking earned value and invoicing. These planning documents were submitted to the Navy for review and approval.

Understanding the potential for hurricane related delays, we created additional schedule float by accelerating mobilization during finalization of project plans to begin preliminary field activities. H&S also ensured that all subcontracts for transportation and disposal were completed prior to commencement of field activities and that additional trucks were available to accelerate offsite transport of stockpile debris in the event of a hurricane. Two highly experienced operators with tracked excavators cleared vegetation and excavated debris. An articulated dump truck hauled debris on a cleared roadway through the forest to a stockpile area for segregation prior to transport for recycling and disposal. We weighed trucks with onsite scales to minimize transportation costs and allow timely notification of removal of 75% of contracted quantities. When a hurricane was heading toward the site, we accelerated critical path activities such as excavation and stockpiling of debris and offsite shipping by working extended hours and ordering additional trucks to ensure no material was stockpiled onsite when the storm hit.   After removal of all debris, our technicians collected and analyzed soil verification samples from each excavated area. After demobilizing we prepared a final report summarizing field work, analytical results, weights of debris recycled and disposed, and shipment manifests.

• Assisted  NWS achieve waste minimization goals by segregating and recycling 25% of excavated debris and reduced transportation and disposal costs by 50%
• Accelerated critical path tasks to avoid hurricanes and complete field work 3 weeks ahead of schedule
• Completed over 1,500 labor hours with zero OSHA reportable incidents implementing proactive safety procedures including alteration of work hours and maintaining hydration during high heat and humidity periods and ensuring compliance with safety zones around construction equipment
