TECHNICAL CALCULATION AND ESTIMATOR'S MAN-HOUR MANUAL
by: Marko Bulic
PIPING ABOVE GROUND
The estimate points of basic erection items are used for payment and monitoring of the works progress during erection of piping above ground. One estimate point equals one man hour (Mhr) at Productivity Efficiency Percentage (PEP) of 90% for unit quantity and for carbon steel. The tables contain the values of erection items for dimension used most frequently in erection of piping. Any intermediate value can be calculated for the needs of an estimate or derived by interpolation. Under the section EXPLANATION TO THE ERECTION ITEMS, the estimate points and the related activities are given for items 1.1 to 7.5. The same section (items 8.1 ÷ 8.8) provides the method for calculating the activities derived from basic items. The influence of different material is calculated by the material multiplier factors (factors for different kind of materials) (f) for items 2.2 to 3.8. By way of an exception, the factors (k) on the page 142 are used for items 1.1 to 1.3. The section FORMS FOR CALCULATION OF MAN-HOUR RATES contains the erection items on< which basis the time required for installation of each piping element is calculated. These forms have been used to calculate all man hour rates in the section.
