Question…

When should you document a delay in the schedule? As soon as you realize there’s an impact

How do you Mitigate Delays?

  • Watch for trends with trouble subs
  • Always document the delay first
  • Understand the impacts and who’s

responsible

  • Make a copy of the schedule
  • Prepare acceleration options

  • Open communication between Scheduler and

Project Team

  • Information that the Scheduler needs
  • Death by 1,000 cuts / Measles

Steps to Maintain Documentation

slide-22
SLIDE 22

Open Communication

The project team needs to let the Scheduler know of all major changes if there is a potential for schedule impact

slide-23
SLIDE 23

Information the Scheduler Needs

  • What’s the trigger?
  • Date any

documentation was issued (RFI, ASI, etc.)

  • Copy of the actual

document

  • If added scope, develop

delay Fragnet

  • What activities are

being impacted?

GRANITE MOUNTAIN Impa pacts S Suc uccess essful ully O Over ercome Thr hroughout t the P he Projec ect

  • Power Pole – The power pole supplying the main power to the existing building was replaced with a below-grade power feed.
  • Rock Slide – Boulders sheared off the face of the mountain landing where the new building needed to be built.
  • Asbestos – The asbestos survey was found to be inaccurate causing a large amount of additional asbestos to require abatement
  • Lead Paint – The hazardous material survey was found to be inaccurate requiring additional lead paint to require abatement
  • Existing Operations – Employees were much more sensitive to dust, noise, and odors than expected.
  • Ground Rock – The soils report indicated that below-grade rock should not have been as large an impact as it was.
  • Avalanches – Snow and ice slide threats were not expected to impact the project as much as they did.
  • Rock Pinning and Analysis – The need to pin rock and analyze the threats to safety were not expected.
  • Winter – The project was originally expected to span one winter, but was required to span two.
