The  area  where your  project  is to  be  constructed  should be  checked  to  see  if the  proper
        experienced craftsmen are available locally or if you will have to rely on travelers  to fill your
        needs. Can and will your organization  pay the  prevailing  wage rates?

        Example:  Let us say that for a project  in a given area we have found  our labor relations  to
        be fair  but  feel that they  could be a little better. Since this is the  case, we arrive  at an  effi-
        ciency rating  of 65% for  this  element.
      4.  JOB CONDITIONS

        What is the scope of the work and just what is involved in the job? Is the schedule tight or do
        you have ample time to complete the project? What is the condition of the site? Is it high and
        dry and easy to drain or is it low and muddy and hard to drain? Will you be working around a
        plant already  in production? Will there be tie-ins making it necessary  to shut down various
        systems of the plant? What will be the  relationship  between  production personnel  and con-
        struction  personnel?  Will most  of your operations  be  manual or mechanized? What kind of
        material  procurement  will you have? There are  many items that  could be considered here,
        dependent  on the  project;  however, we  feel  that  the  most  important  of these  items  that
        should be analyzed under  this  element  are  as  follows:

                       a.  Scope  of work
                       b.  Site conditions
                       c.  Material  procurement
                       d.  Manual and mechanized operations

        By  careful  study and  analysis  of the  plans and  specifications  coupled with a site  visitation
        you  should be able to correctly  estimate  a productivity  efficiency  percentage for this item.

        Example:  Let us say that the project we are estimating is a completely new plant and that
        we have ample time to complete the  project but  the  site location is low and muddy. There-
        fore,  after  evaluation we estimate a productivity rating of only 60%.
      5.  EQUIPMENT

        Do you have ample equipment  to  do your job? What  kind of shape  is it  in? Will you have
        good maintenance and repair  help? The main items to study under  this  element  are;

                       a.  Usability
                       b. Condition
                       c.  Maintenance and  repair

        This  should be the  simplest  of all elements  to analyze. Every  estimator  should know what
        type and kind of equipment his company has as well as what kind of mechanical shape it is in.
        Example:  Let us assume that our company equipment is in very  good shape, that we have
        an ample supply to draw from,  and that we have average  mechanics. Since this is the  case
        we estimate  a productivity  percentage  of 70%.
