  • Note that Method 1 will always give you what you want to hear (on budget, on time), not necessarily the reality of what’s happening on site. For example, 7 remaining days is odd – one week and two days for one person, or 3-1/2 days each for two guys.
  • This seems like a quick response that says, “yeah, a couple of guys next week.” While it doesn’t sound like a big deal, not managing the work more than halves the desired profit.
  • For example, if the supervisor pushes to meet the budget, there is still enough profit in the job to have something left for a bonus, but if (s)he lets it slide to the 10 days, there is not only no bonus but there is barely any profit for the time spent.

    8. 8.  Physical evaluations of mandays to complete (by phase) are important to effective job cost control and management PM should periodically walk job with Superintendent to ensure estimates properly reflect ETC Unexpected variances should be investigated promptly for causes and potential remediation. Possible explanations: • Change orders need to be priced • Productivity issues on site • Problems with original estimate Failure to get good ETC information makes remediation difficult, if not impossible! and perhaps….
