In SIPL, we’re committed to provide quality and reliable instrumentation and monitoring results for our clients, especially in time where geotechnical and structural instrumentation has become an integral part of construction process. SIPL supplies and installs the full range of soil deformation, settlement, pressure and water level instruments for geotechnical monitoring purposes. Similarly, SIPL also provides the full range of structural instrumentation to help engineers monitor structural deformation, movement, tilt, vibration, noise, strain and load.

SIPL introduced cableless instruments into Singapore in 2008, varying from EL Tiltsensors to Crackmeters, and has since been employing them in multiple projects to great success. The cableless instruments have since proven to be highly suited for the urban environment in Singapore. The cableless instruments are produced by Soil Instruments Ltd, UK, a leading instrument manufacturer in the world. SIPL is proud to be the official distributor of Soil Instruments Ltd equipments in Singapore.

• Monitoring slopes and landslides to detect zones of movement and establish
  whether movement is constant, accelerating, or responding to remedial
  measures.
• Monitoring diaphragm walls and sheet piles to check that deflections are within
  design limits that struts and anchors are performing as expected and that
  adjacent buildings are not affected by ground movements.
• Monitoring dams, dam abutments, and upstream slopes for movement during
  and after impoundment. Monitoring the effects of tunneling operations to
  ensure that adjacent structures are not damaged by ground movements.

ELs are used to monitor changes in the tilt of a structure. Tilt changes may be caused construction activities, such as excavation, tunneling, and dewatering that affect the ground that supports the structure. Changes in tilt may also result from loading of a structure, such as the loading of a dam during impoundment, the loading of a diaphragm wall during excavation, or the loading of a bridge deck due to wind and traffic.

Typical applications for ELs include:

• Monitoring stabilization measures, such as pressure grouting and underpinning.
• Monitoring structures for the effects of tunneling and excavating.
• Evaluating the performance of bridges, beams, and dams under load.
• Monitoring the stability of structures in landslide areas.
• Monitoring the deflection and deformation of retaining walls.
• Monitoring convergence and other movements in tunnels.
• Providing early warning of threatening deformations, allowing time for
   corrective action to be taken or, if necessary, for safe evacuation of the area.

• Monitoring pore water pressures to determine safe rates of fill or excavation.
• Monitoring pore water pressures to evaluate slope stability.
• Monitoring dewatering systems used for excavations.
• Monitoring ground improvement systems, such as vertical drains and sand
   drains.
• Monitoring pore pressures to check the performance of earthfill dams and
   embankments.
• Monitoring pore pressures to check containment systems at landfills and
   tailings dams.

Total pressure cells measure the combined pressure of effective stress and pore-water pressure. In general, pressure cells are used to verify design assumptions and to warn of soil pressures in excess of those a structure is designed to withstand. Typical applications include:

• Determining the distribution, magnitude, and directions of total stresses in an
   embankment or in the clay core of a dam.
• Confirm that tailing material is densifying at design rate.
• Estimate overburden pressure acting on foundation.
• Measure contact pressures in abutments and foundations.
• Measure stress fields in shotcrete.

Load Cell

Center-hole load cells are designed to measure loads in tiebacks, rock bolts, and cables. Typical applications include:

• Proof testing and performance monitoring of tiebacks, rock bolts, and other
   anchor systems.
• Monitoring loading of vertical supports in underground openings.

Borehole extensometers are used to measure movements of soil and rock along the axis of a borehole. A wide range of extensometers is available, each designed for a particular application. In general, typical applications include:

The spiral sensor is employed to check the twist of inclinometer casings after installation in the ground.

Crackmeter is used to monitor movement at joints and cracks in concrete structures or rock. 

We use the world's frontrunner in vibration monitoring equipment - Instantel - for all our vibration monitoring works.
