Breakout Session: CPM Scheduling

Transcription

1 Breakout Session: CPM Scheduling The Full Potential of the CPM Scheduling Process Brandon Howell January 29, 2019 LAYTONCONSTRUCTION.COM 2 nd most common cause of disputes in 2016 was poorly drafted or 1/3 of all construction contracts end in dispute incomplete / unsubstantiated claims - Arcadis: 2017 Global Construction Disputes Report

2 What We Will Cover Scheduling 101 How to organize and manage your schedule as a defense tool Key data to monitor in the schedule to avoid liability in the case of claims Steps needed to maintain documentation during the scheduling process

3 Schedule in a Nutshell

4 Organizing your Schedule as a Defense Tool How to document delays Backup documentation

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

6 Delay Fragnet Example

7 Weather Delay Example

8 Use the Notebook

9 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

21 Steps to Maintain Documentation Open communication between Scheduler and Project Team Information that the Scheduler needs Death by 1,000 cuts / Measles

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

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?

24 Death by 1,000 Cuts Numerous or constant changes to the project

27 GRANITE MOUNTAIN IMPACT ANALYSIS

28 GRANITE MOUNTAIN Impacts Successfully Overcome Throughout the Project 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.
