Scheduling / Fast Tracking
We've all been there. The customer or the calendar demands a quicker than planned completion to the project. Should you consider fast tracking to compress the schedule? Can you fast track, without back tracking through new costs or delays?
Fast tracking is a simple concept. "A Guide to the Project Management Body of Knowledge – Third Edition" (or PMBOK® Guide) defines fast tracking as a schedule compression technique "where phases that normally would be done in sequence are performed in parallel." However, the PMBOK Guide also warns that fast tracking can result in rework and increased risk. While fast tracking trades cost for time, it can actually increase the risk of achieving a shortened schedule.
Decommissioning and Decontamination
Abstract – Conventional hydrolasing (water blasting at high pressure) has been employed throughout the decommissioning and decontamination industry to decontaminate radioactive surfaces for a number of years. It has traditionally been viewed as a technology reserved for difficult, labor-intense projects that could not be accomplished by other technology.
Perhaps one of the most significant drawbacks to conventional hydrolasing has been that it traditionally generated large quantities of wastewater, which required expensive secondary waste handling.
Dry decontamination methods, such as shaving and scabbling, can be simple, effective methods of decontamination for concrete floors, but they meet with limited success in vertical and overhead applications.
Other methods, such as chemical peeling, can work well on steel surfaces, but meet with limited success on porous surfaces, such as concrete.
It has now been demonstrated, through a real-world application, that small-scale hydrolasing can be effectively deployed for structural decontamination projects of only a few thousand square feet. Additionally, it is far superior for decontaminating vertical and overhead surfaces. By incorporating a proven small-scale water recycling system with the proprietary hydrolasing and waste recovery technology developed by TMR Associates, L.L.C., small-scale hydrolasing is a better alternative than baseline technologies.
