Barr & Prevost provides QC/QA testing and inspection services for Portland cement concrete, mortar and grout, and hot mix asphalt performed by ACI and ODOT-certified technicians in the field and our laboratories. We operate testing facilities in Columbus (2 miles from Port Columbus International Airport) and Cleveland, Ohio (Centrally Located Downtown). In-field testing and inspections are performed at the construction site or at the material batch plant. Field vehicles are fully outfitted with testing equipment and supplies, and we utilize a climate-controlled trailer for on-site storage of concrete test cylinders when environmental conditions are expected to be outside acceptable parameters. Laboratory tests are conducted at our AASHTO R18 certified testing facility. Our lab facilities, equipment, and personnel are regularly inspected and evaluated by the AASHTO Materials Reference Laboratory (AMRL) and the Cement & Concrete Reference Laboratory (CCRL). In addition to hard copy records, Barr & Prevost posts all field and laboratory test data and logs on our secure login website for easy reference and retrieval by our clients.

Barr & Prevost offers comprehensive construction inspection services and a well-qualified team of inspectors with a wealth of field experience and expertise in various engineering and technical disciplines. Services are typically provided by Barr & Prevost personnel posted on-site on a full-time basis throughout the construction process or during specific stages of a project and range from construction management and administration, to visual and hands-on inspection, to field sampling and testing of materials. As a corollary service, our two materials testing laboratories (Columbus and Cleveland, Ohio) provide scientific analysis for concrete, rock, soils and aggregate . Our inspectors and project managers ensure that contractors comply with all contract requirements, structural and material specifications, applicable safety ordinances and regulations, and other regulations. At the construction site, they catalog daily inspection reports and corresponding photographic logs, and various records such as issued permits, and they keep detailed checklists that document the ongoing status of a project. This diligent record keeping is crucial to managing contractor pay requests, helping ensure that distributions to contractors are consistent with the verifiable percentage of project completion at any given point in time. In addition to hard-copy records, all documentation concerning a project, including field and laboratoryâ¦

Barr & Prevost provides a full range of drilling services in support of geotechnical investigations. Our drilling technicians perform sampling of soil and rock for field and laboratory testing that reveals critical information about the subsurface conditions and materials at a project site. Barr & Prevost operates two rotary drilling rigs (one truck-mounted and the other ATV-mounted) and one direct push Geoprope unit (typically used for environmental drilling) from our Columbus, OH and Cleveland, Ohio Laboratories. We also maintain access to additional lease/rental equipment, including skid-mounted CME45 rigs. Technicians are trained in field classification and the preservation and transport of geotechnical soil samples and rock cores, and have accumulated significant field experience in providing drilling services for a wide range of civil and architectural projects including bridges, roadways, trails, buildings, towers, airports, and water treatment facilities.

Barr & Prevost is a recognized leader in geotechnical engineering. With an experienced team of geotechnical engineers, geologists, drillers, and field and lab testing technicians and supervisors, and with our own AASHTO-accredited testing laboratories, we are ideally positioned as a single-source for comprehensive geotechnical engineering services for civil infrastructure and architectural projects. We are prequalified with the Ohio Department of Transportation (ODOT), the Kentucky Transportation Cabinet (KTYC), and the West Virginia Department of Transportation (WVODOT) to provide various geotechnical engineering services for projects under their respective jurisdictions. From initial project planning and site reconnaissance; to subsurface investigation and laboratory testing; to analyses, recommendations, and design for foundations, earthwork, dewatering, ground improvement and stabilization â we offer our clients innovative, cost-effective solutions and the convenience of a suite of related services. And, because we are able to provide all geotechnical engineering services in-house, project management is significantly streamlined, ensuring delivery of accurate and reliable data, and superior communication with stakeholders.

Barr & Prevost provides geotechnical testing services through our AASHTO-accredited testing laboratories. Our geologists and trained technicians, under the direction of our geotechnical engineers and lab management, perform a host of tests and analyses related to soils and geotechnical investigations. The combination of a well-equipped laboratory facility and a deep roster of technical staff allows Barr & Prevost to manage the processing and testing of a large volume of soil and rock samples at any given time; thus, we can handle virtually any size testing assignment. Staff expertise and ongoing training in the use of gINT geotechnical data management software helps ensure that logs and test data are managed efficiently and that reports are standardized, and our secure login website allows clients access to test data at their convenience. Barr & Prevost provides supporting services through our drilling division, whose technicians are experts in soil sampling and rock coring. And, in addition to laboratory testing, we offer in-field geotechnical testing and related construction inspection services. These services are performed during earthwork or excavation for the purpose of qualifying load-bearing surfaces or areas as being in conformance with project requirements and/or specifications and include: Subgrade, subbase, and base course inspection;In-place densityâ¦

The Barr & Prevost underwater inspection team conducts the visual and hands-on inspections of submerged portions of bridges (or other structures) and documents its findings and recommendations in technical reports. Our scuba-certified diving personnel are experienced ODOT Level II Bridge inspectors, and include licensed professional engineers. Each team member contributes expertise in applicable engineering disciplines or technical skills which collectively result in efficient and safe underwater inspections that provide our clients with detailed and accurate observations, data, and analysis that allow for informed decisions regarding structure safety and options for rehabilitation. With the addition of underwater inspection to our services portfolio, Barr & Prevost is one of a select group of firms that can offer its clients truly comprehensive, top-to-bottom bridge inspection services for virtually any structure or site. This vertical integration allows our project managers to coordinate all aspects of a bridge inspection job utilizing in-house resources, enhancing their ability to maintain consistent quality control and keep tasks on-schedule and within budget.

Accuracy in survey measurements and calculations is critical to a projectâs success, providing the foundation underlying design development. The Barr & Prevost team of licensed professional surveyors, qualified party chiefs, and supporting personnel provides our clients with the right combination of training, and field and practical design experience that makes for an accurate and well-managed survey. Surveying is not a static engineering discipline, and new technologies have emerged that allow us to offer our clients an innovative approach to surveying that assures accuracy and lower costs. To this end, in addition to the use of conventional surveying equipment and methodology when and where appropriate, Barr & Prevost is equipped with the most current GPS survey equipment and reflectorless technology. The use of GPS equipment allows for rapid field data collection (typically, up to 1200 field shots per day under favorable conditions) with a reduced field crew size, while reflectorless total station technology eliminates the need for need for a prism rod (and the need for a rod man) for many survey tasks. Significantly, the use of reflectorless technology allows survey data to be obtained âin-trafficâ without the need to close lanes and cause inconvenience to the traveling public. We haveâ¦
