Factors are generally considered a ratio of the total cost of installing a process plant proportional to the cost of its major Mechanical components. Parametric estimating is the use of statistic applied to a number of or single known value to develop an order of magnitude cost.
Steam turbines should not be seen as unduly complex mechanical installations, you will generally be provided with a modular unit such as a Siemen’s or MAN MARC machine, these machines are preassembled on skids, for smaller units say 1.5 to 12 mw that could be one skid, whereas larger units up to 40 mW. can be in preassembled modules e.g. Turbine skid, gear box, lube skid and generator.
This is a general guide to show the reason for the man-hours attributed to the mechanical installation of a pump. In this instance the procedure refers to a slurry type pump either Z drive of direct coupled with no oil cooler or disassembled drives. A typical 8×6 or 10×8 pump say. The procedure will cover a wide range of sizes and types as it is consonant across types and sizes.
Unpacking of the machine needs to be allowed for in the installation estimate as well as the removal of packing and surface protection films. Only those components ready for the installation at any specific time should be unpacked, do not unpack all items and prepare as surfaces and bright finished can be damaged prior to installation. man-hours 40.
