PREFACEAll 40 years of my working life, I spent on erection of different process plants most of which were oil industry projectsin the country and abroad, in Europe and North Africa. Since 1978 with occasional interruptions because ofsimultaneous involvement in several different projects, I worked mostly on technical calculations. I have madehundreds and hundreds calculations based on all kinds of tenders and erection of mech anical equipment. Thetenders were written in various foreign languages and alphabet, even in Cyrillic. I am fully aware of the problems anestimator encounters when working on technical calculations for specific technologies. Very often tenders were notcomplete and not detailed enough, and the time required for a good technical calculation is getting every dayshorter. It is not easy to present exact technical figures and quantities for the equipment or operations not fullydefined, hard to comprehend, or even unknown to the estimator. Technical terms and expressions written indifferent languages and dialects are often incorrect and specific for individual branches. Enormous experience isneeded, an ability to assess and estimate, and even the courage to write down the technical quantities and figures.That was the reason for collecting various technical bibliography, standards, catalogues, man hours and rates fromthe European and USA countries. I have made the analyses, comparisons, simulations, new measures, and manhourtables. A great deal of that was verified in practice during the plant erection. I surveyed the results and analyses ofas-built designs. On many occasions, I sought a compromise between different opinions and standpoints. Too manythings collected on too many places. Finally, I decided to write this manual for discriminative estimators. It isimportant to understand that there are no identical projects or jobs in this business, that each project is specific andthat no automatism or copying is possible. Approach to any job should be serious and professional and a technicalcalculation should be made with the assistance of this Manual. Many people try to include the man hours from thetables into the computer systems, which I oppose. Those are the people, which instead of using a computer, acomputer uses them. An estimator himself must choose the values and define the man hours taking into account allthe elements that might have any influence on them. Only when the relevant man hours are estimated and selected,a computer can be used. A saying “Switch on your brain before switching on the computer” should be followed.The most complex work in developing these man hours was the work on the man hours for piping above ground. Abasis I used was a system for estimating the value of erection works of a German Company LINDE, which Icompleted and modified. Generally, for elaboration of the man hours for erection/installation of process equipment,I used the English man hours of the Oil and Chemical Plant Constructors Association, but I used other sources aswell.The source or the author was noted for other tables and if I modified them, I provided the modification basis. Wherethere are no such notes, I am the only author.A complete edition of this manual in the Croatian language and its sections were published in 1997 and2000. This is why I have not given a unified percentage of the production efficiency but each chapter has its own.Marko BuliæZagreb Croatia, 20032
