Advantage Engineers provided geotechnical engineering services during the construction phase of the Squadron Operations and Training Facility. Services include the full-time, on-site engineering review and oversight of the following:
- Erosion and sedimentation control activities
- Placement of structural fill
- Construction of storm drainage features
- Utility installation
- Foundation and slab construction
- Structural steel erection
- Installation of paving elements
- Laboratory testing of construction materials to verify conformance with project specifications, including concrete, masonry and grout specimens.
The Squadron Operations and Training Facility (SOTF) is a 23,000 square foot facilities that replaces five semi-permanent and functionally obsolete World War II era buildings and will consolidate numerous squadron functions. The design utilizes relatively new and environmentally-conscious insulated concrete form (ICF) walls for the exterior walls. With a construction cost of just over $6 million, this project has been considered one of the most mission-essential by the PAANG.
Advantage staff and field technicians provided complete oversight and on-site testing and monitoring of all excavation and structural fill placement, including:
- Inspection of the foundation sub-grade for bearing capacity
Monitoring all preparations for concrete to include:
- sub-base, base course, vapor barriers, reinforcing steel, and formwork
- Testing of all cast-in-place concrete and masonry activities
Over 200 sets of concrete compressive strength test specimens were cast and tested for the project. Advantage conducted destructive and non-destructive testing of hardened concrete when the competency of some elements was questioned. Advantage also completed testing and inspections of the sub-grade and sub-base for all gravel access roads and asphalt roadways and parking areas, as well as monitoring all of the asphalt paving activities.
Prior to construction, Advantage completed a thorough review of the plans and specifications to determine the full extent of testing and monitoring activities required. This complete list was reviewed by the contractor and the owner’s representatives to ensure no unnecessary testing is completed during construction. Advantage also prioritizes and managed personnel across several projects in the same geographical location to reduce the number of technicians required to monitor the work. Effective communication during construction between Advantage field technicians and the contractors (General Contractor as well as the sub-contractors for earthwork, concrete and masonry) limit unnecessary site visits and help to minimize on-site “billable” hours. Additionally, the ability of Advantage field technicians to provide immediate problem analysis and recommendation of solutions on several occasions has reduced contractor down-time and prevented construction delays.
