C30 SHORING/FACADE RETENTION
NOTE: The requirements for shoring and strutting for the formation of large openings are dependant upon a number of factors, for example, the weight of the superimposed structure to be supported, the number (if any) of windows above, the number of floors and the type of roof to be strutted, whether raking shores are required, the depth to a load-bearing surface, and the duration the support is to be in place. Prices, would therefore, be best built-up by assessing the use and waste of materials and the labour involved, including getting timber from and returning to a yard, cutting away and making good, overhead and profit. This method is considered a more practical way of pricing than endeavouring to price the work on a cubic metre basis of timber used, and has been adopted in preparing the prices of the examples which follow.
