INTRODUCTION
The Windsor HP Probe system rapidly and accurately determines the concrete compressive strength of a structure by driving a probe into the concrete with a known amount of force. It is non-destructive and can be used with equal effectiveness on fresh and mature concrete. Equally accurate results are obtained on horizontal or vertical surfaces provided that the probe is perpendicular or at right angles to the test surface. 2.0
OBJECTIVE
This work method statement is to measure the compressive strength of concrete accurately and effectively, on-site in the field by Windsor HP Probe System and the sequence of works if failure occurred during the determination of compression test on concrete cubes.

TESTING PROCEDURE
1. The concrete to be probed must have reached a sufficient degree of resistance to penetration. (Not more than one half the thickness of the concrete). 2. No probe shall be located less than 178mm from any other probe, nor less than 102mm from the edge of a concrete surface. 3. The surface should be reasonable smooth. Surfaces coarser than a broom finish shall be stoned or ground over an area larger than that covered by the positioning device and measuring base plate to be used.

4. Place the positioning device on the surface of concrete at the position to be probed. Mount a probe in the driver unit, position the driver and probe in the positioning device, and fire the probe into the concrete, following the direction supplied the apparatus. 5. Remove the positioning device and test the probe for firmness of embedment. Reject any probe that is not firmly embedded. 6. Place the measuring base plate over the probe and position it firmly on the surface of the concrete to prevent from other movement and without rocking. 7. If the surface of the concrete has been raised around the base of the probe, the crushed concrete may have to be removed to allow the reference plate to lie flat. 8. Install the probe measuring cap and the plate retainer as appropriate, and measure the distance from the reference plate to the end of the probe or to the reference plate to the end of the probe or the upper surface of the measuring cap, to the nearest 0.5mm. If the probe is slanted with respect to the surface of the concrete, make four measurements equally spaced around the parallel to the probe and average to get the measurement. 9. The measured average value of exposed probe length may then be used to estimate the compressive strength of concrete by means of appropriate correlation data. 10. Windsor probe test system has published tables relating the exposed length of the probe with the compressive strength of the concrete. For each exposed length value, different values for compressive strength are given, depending on the hardness of the aggregate as measured by the Mohs' scale of hardness.

QA/QC ASPECT
The purpose of the quality control is to provide a guideline for a proper operation framework such that the following targets will be attained:
To achieve consistently high quality standards of workmanship in all aspects of the work.
All quality matters shall follows as per MS ISO 9001 : 2000 and Project Quality Plan to ensure the quality in construction.
9.0
SAFETY AND HEALTH ASPECTS
All equipment are to be checked at the beginning of work to ensure that it is well functioning and safe to be operated by competent operator. 9.1 SAFETY FEATURES
All supervisors and general workers are to wear safety goggle, safety helmet, safety jacket, mask and safety boots when entering to site. Safety belt/harness will be used if work at high place. 9.2 SAFETY PLAN
Site personnel and workers are compulsory to attend Safety Induction Training conducted by Vale’s Safety Department
Safety helmets and safety footwear should be worn. Working sites are often very wet and the use of rubber boots is essential.
The site shall be kept clear of unnecessary obstruction First aid boxes in the charge of a responsible person have to be kept on all sites.
If the entrance to a site crosses a public road or footpath this should be kept clear of obstructions, mud and spoil.
