The Cost of Problems
Problems are not usually recognized until you are right in the middle of them - at this point the problem will cost about 30% to fix - so if you are in the middle of a $1,000 piece of work and discover a problem it will cost about $1,300 before you are done.
In the worst case, when problems are discovered after the work is complete it will cost up to 80% to fix.
Our focus needs to be on spending whatever resources are necessary to identify and solve problems BEFORE we are in the middle of construction.
A 5,000 Man Hour Project
Pre-planning is just what it sounds like - it is about taking the time that is normally spent on planning throughout the project and shifting it to the beginning of the project.
When you look at what happens during the day for one person it just looks like a few minutes and it seems impossible to save any real time. Let's look at a 5,000 hour project and how the time is spent in the field.
Over a 1 year, 5,000 man hour project there are 6-7 hours per day spent on non-installation activities; a total of 1,800 man hours. We can plan our attack by focusing on four key areas:
1. Plans & layout - 11%, 550 hours
2. Material Logistics - 6%, 300 hours
3. Mobilization, cleanup and site movement - 13%, 650 hours
4. Breaks and other non-productive time - 6%, 300 hours
Planning & Layout - Where Can You Be Most Efficient?
There is no question that planning and layout has to be done. The question is when and where can it be done most efficiently?
o Pre-planning is about moving as many of the field layout, coordination and planning issues to the front of the project as possible.
o Pre-planning is about taking the activity out of the field and into a controlled environment that is specifically designed for efficient planning.
o Pre-planning is about taking advantage of tools that allow more accurate layout and communication of ideas.
o Pre-planning is about finding and resolving problems before you start working to minimize disruptions to progress and re-work.
o Pre-planning is about locating value-engineering and pre-fabrication opportunities well before construction starts.
There is no hard and fast rule about what pre-planning looks like. The process will look slightly different for each company and project type.
The goal is to build a culture into the company where people seek out opportunities to shift work from the project to a more controlled environment. It is about shifting the thought process from being reactive to proactive.
