Project Title: Multi-year IDC, Comprehensive Environmental Contract
Client: U.S. Army Corps of Engineers, Tulsa District
OAS has provided various environmental services under the Tulsa District’s Comprehensive Environmental Contract. Those services include excavation, demolition, hazardous waste management, database creation and maintenance, and MEC/UXO support during construction activities.
Industrial Waste Treatment Plant Debris, Piping and Structure Removal Project, Formerly Used Defense Site, Laredo AFB, TX - This Fixed-Price Task Order was executed under the Indefinite Quantity Cost Reimbursable/Fixed Price Comprehensive Environmental Contract. The purpose of the task order was to remove remaining structures, piping, and treatment processes from the site of the Industrial Waste Treatment Plant of the former Laredo Air Force Base. Project activities involved removal of the industrial waste plant structures, piping and drying beds materials at the former Laredo AFB, and re-grading and re-vegetating the area to original conditions. OAS prepared a Project Management Plan and Site Specific Health & Safety Plan and made presentations to various City of Laredo municipal departments in order to obtain utility clearances prior to mobilization to the site. Waste manifest preparations, as well as waste disposal and permitting, were also performed prior to the site operations. OAS conducted an asbestos survey and removed all liquids from the structures prior to the demolition activities. Unanticipated conditions such as a severe bee infestation, buried Transite piping and the discovery of buried structures required additional efforts for this fixed-price contract.
Cost Reimbursable Contract for Tar Creek Program Wide Support - The initial task for this proposal was the assimilation of the actual documents identified in the bibliography, scanning of the documents into a PDF format and delivery of the scanned documents to the Corps of Engineers for posting on a FTP web site for subsidence team members to access remotely. OAS located the 250+ published documents listed in the bibliography, scanned the documents in accordance with all applicable copyright laws, and deliver the scanned documents in a PDF format on a weekly basis via CD’s or DVD’s to the Corps of Engineers technical manager. OAS also created a website and uploaded the documents onto an FTP site for use by the Corps of Engineers Subsidence Evaluation Team members during the subsidence evaluation phase. The files, which became part of the electronic record for the subsidence team effort, were placed in a designated data repository to be held indefinitely after the project was completed. Because of the money saved by the OAS document acquisition approach, a library of maps was also scanned and saved within the original cost estimate
MEC Support for Construction by Others, Southwest Cantonment Area, Fort Sill, Oklahoma - The OAS/MEC Team provided Unexploded Ordnance (UXO) standby and avoidance support for potential MEC within the Southwest Cantonment Area of Fort Sill, OK. The objective of the MEC support for construction by others was to provide standby support and avoidance of potential MEC during the performance of construction activities by others within the SW Cantonment Area. The MEC Team provided all labor, materials, and equipment necessary to perform MEC standby support during construction activities in accordance with EP 75-1-2. The MEC Team furnished the required UXO-qualified personnel, equipment, instruments, and transportation, as necessary, to accomplish the required services. During the implementation of MEC support activities, the team provided required professional supervision and quality control to ensure the quality, safety, and completeness of the work. Duties of the MEC Team met were to meet with on-site management and construction personnel to conducted the general work and safety briefings prior to the start of on-site activities. The MEC team monitored excavation activities in areas potentially containing MEC. When MEC was observed, all excavation activities were stopped until the condition of the MEC item was determined and a disposal decision was made. MEC was reported to Fort Sill Range Operations and safeguarded by the UXO Team until arrival of the appropriate authority. Excavation activities did not resume until the MEC item had been removed by Explosive Ordnance Disposal (EOD). Two UXO Technicians were provided on-site each 10-hour workday for each six-day workweek. The personnel were UXO qualified as outlined in DoD TP-18. The Senior UXO Technician on site prepared a daily report which accounted for the activities for that day. The MEC team posted the report electronically each day to an FTP site for QC and review by the USACE Project Manager.
