    Soil Investigation

    Field Drilling

    We provide cost-effective, responsive and quality soil investigation works with A-frame and top-drive drilling rigs (with or without crawlers). Our experienced drilling personnel can provide drilling and coring in various ground environment and sample sizes. We have full range of services such as borehole sizes of 75 and 100mm diameter, UD sampling, thin-wall sampling, piston sampling, Mazier sampling, rock coring of 52 and 65mm diameter, standard penetration test (SPT), vane shear test and permeability tests, etc.

    Geophysical Survey

    Geophysical survey is ground-based physical sensing techniques used to detect physical properties of the substrata geological information such as ground penetration radar (GPR), parallel seismic, P-S logging, 2D 3D reflection seismology, seismic refraction and electrical resistivity tomography, etc.

    Marine Soil Investigation

    We have facilities for both nearshore and offshore investigation works. Our pontoon allowed us to conduct SI works in lake, river and intertidal zones. Our powerful crawler CPT allowed us to complete tests on intertidal beach in just a couple of hours. Our high-torque drilling rigs with jack-up barge gave AECOM Consultants and MPA officers stunning impression of speed and quality.

    Plate Load Test

    Plate load test is to determine the load capacity of soil and likely settlement under a given load. It basically requires to dig the ground to a given depth of the foundation level, apply load on a steel plate and record the soil responding behaviours. Our plate test is SAC-SINGLAS accredited to BS 1377 test standard

    Instrumentation and Monitoring

    Vibration and Noise

    Vibration induced by piling and demolition works affects structural integrity and must be monitored manually or by real time, which is mandatory by BCA. Noise generated by construction activities during daytime and night affect health of residents as noise pollution, which is closely monitored by NEA.

    Ground and Structural Monitoring

    Extensive ground and structural monitoring is required for building and construction projects such as ground settlement marker, utility settlement gauge, crack meter, tilt sensor and tape extensometer, etc. for measurement of structural and ground deformation, movement and tilt, etc.

    Borehole Type Instruments

    These are used to measure the lateral, vertical underground soil movement, changes of underground water level and water pore pressure, and compressive ability of soil layers, etc. Bore holes have to be drilled in appropriate diameters so as to install with the instruments such vertical or horizontal inclinometer, water standpipe, piezometers, rod extensometer, and recharge or relief wells, etc.

    Real Time Monitoring for Excavation and Tunnel

    Singapore is a city state with extensive underground MRT network, and deep excavation activities are common for high rise building and infrastructures due to land scarcity. Real time monitoring of tunnel movement, track alignment and tilt is significantly important for safety and operation of the trains through usage of automated tunnel monitoring system (ATMS). Force and movement monitoring of deep excavation is the most necessary tool for safe construction and supervision of the civil engineering works through strain gauge and load cell.

    Pile Instrumentation and Testing

    These tests on piles include the ultimate load test, PDA, PIT and cross hole sonic logging, etc. Our tests are SAC-SINGLAS accredited.

    Structural Health Monitoring Using FOS

    Structural Health Monitoring Using FOS

    We supply and install structural health monitoring systems using various sensors such as fibre optic sensor, corrosion sensor and thermal sensor, etc to structural integrity monitoring during construction stage and full life span of the building and structures. The long-term SHM for 50 years and longer aids designers and developers to lower design and construction cost and enhance structure performance. SHM aids structure owners to reduce ownership cost and prolong structure availability.

    FRP Fibre Wrap

    FRP Fibre Wrap

    This is to use carbon, glass or kevlar Fibre Reinforced Plastic (FRP) to wrap on external surfaces of concrete or metal structures to strengthen the flexural and shear capacities due to addition & alteration purpose, rectification of insufficient tolerance of constructed structure, and addition & alteration project and blast protection purposes.
