The construction of foundation for high-rise buildings and infrastructure such as power plants, bridges, flyovers, jetties, airports, harbors, and many other structural buildings need a good control to its construction quality; thus needs a comprehensive testing system which can gives the accurate actual pile capacity. We provide pile capacity test such as;
Dynamic Load Test (PDA + CAPWAP)
Dynamic Load Test (PDA + CAPWAP)
• One of the most popular dynamic load test is the Pile Driving Analyzer (PDA) test which is a nice and simple non-destructive test. PDA test conducted by measuring force and velocity at pile head during driving and analyzed using Case Method. We can estimate pile stresses, integrity, capacity and hammer performance
• PDA test can be done on all deep foundation material (Concrete, steel, or composite)
• The standard test procedure is based on ASTM D4945
• Our new flagship service is rental hammer to support the test up to 60 ton (for 6000 ton pile capacity). The advantages of our hammer are its flexibility in weight and less heavy equipment use, which mean cost efficient.
Static Axial Compression Load Test
Static Axial Compression Load Test
• Static axial load test is the oldest and believed to be the most accurate way to check pile capacity under compression load. The principal of the test is by measuring pile displacement under compression load. Recently, this method is developing to support with more data using instrumentation (load cell, strain gauge, extensometer) where accuracy and detailed data can easily achieved.
• We provide the test in 2 methods, kentledge system (up to 2500 ton) and reaction pile system (up to 6000 ton).
• Standard test method is based on ASTM D1143
Bi-Directional Static Load Test
Bi-Directional Static Load Test
• Bi-Directional Static Load Test (BDSLT) is another compressive load test method. Compare to the conventional method, the BDSLT is a preferable choice when load test require in remote area with limited heavy equipment, a considerable mobilization cost, and safety issue to the stability of test system.
• BDSLT done by preinstalled one (or more) sacrificial jack on foundation rebar cage and later cast together. The load will be provided by a combination of friction and end bearing from the upper and lower part of the jack.
• Standard test method is based on ASTM D8169
Static Axial Tensile Load Test
Static Axial Tensile Load Test
Static Horizontal Load Test
Static Horizontal Load Test
• Horizontal load test perform by two common method; pile to pile and kentledge. The key point in conducting the test is to make sure that load was give at Cut-Off-Level (COL). Additional instrumentation like inclinometer, and strain gauge can also applied. The test perform based on ASTM D3966
