The well-known tag line expressed by Will Ferrell’s title character in the 2006 movie Talladega Nights: The Ballad of Ricky Bobby could have been based on a line reading from any number of different property developers I have known over the years. It is a common refrain heard by the project team from the owner each time another compressed construction schedule is introduced. With advances in technology and process improvements, large scale construction projects can be delivered in a shorter calendar window than they could have even a decade or two ago. It is hard to blame these owners for wanting to put the pedal to the floor on these schedules, but is there a danger in pushing too fast and compressing too much? Can it really be faster to go slower?
Before the building process is off to the races, commissioning authorities (CxAs) are often brought on board at the beginning of the construction phase of a project, if not sooner. This gives us the opportunity to gain from lessons learned repeatedly observing the construction phase from beginning to end. While there is a wealth of opportunity to gain efficiency and value by involving the CxA starting in the pre-design/design phase, this article primarily focuses on the construction phase.
There are many reasons an owner may introduce a condensed program; perhaps a penalty is involved if the site is not ready for assets or people prior to a specific date. Maybe the construction start date pushed out and the owner does not want to push out the turnover date accordingly. In these cases, it can be difficult to push back against the direction to compress the schedule as this direction may come from much higher up than the Owner’s construction project manager. Whatever the reason, it is important to understand the potential consequences and pitfalls that compressing the schedule can generate. Below are just some of the problems that can arise when trying to move too quickly:
Flag #1 – Fatigue: Working long days, weekends, and night shifts for extended periods of time can result in both mental and physical exhaustion. When humans tire and are pre-occupied with counting down the hours until they get home, several negative behaviors can start to emerge. Inhibitions can drop resulting in bad decision making. When people are tired, work gets rushed, miscommunication happens, and small (but important) steps are skipped. These not only negatively impact quality of work but can also be a major safety concern.
Flag #2 – Reduction in efficiency: Sometimes adding additional teams to perform field work can speed up operations; however, that is not always the case. There is quite a bit a truth in the old adage “Too many cooks spoil the broth.” Working with multiple teams in one location requires a significant amount of coordination, perhaps more time and energy is spent on coordination than is actually gained by running the work sequence as originally scheduled. Add in fatigue and the potential for miscommunication means having multiple teams working in parallel can result in majorly detrimental effects on efficiency.
Flag #3 – Increase in the number and severity of issues found during commissioning: The CxA is meant to serve as the final line of defense to catch issues caused by faulty equipment or human error installation. In theory, prior to the final functional testing of any equipment or system, the contractor or vendor has successfully completed their start-up process and should feel confident at that point with handing a functional system over to the owner.
With compressed schedules, vendors can sometimes feel so pressured that they hand over “pencil whipped” documentation where they go through the motions of startup but do not get a chance to back check their work (or the formal startup procedure simply does not get completed at all).
Work may also be completed in a piecemeal manner such that the owner directs the CxA to complete what they can on a piece of equipment and come back later to finish the remainder. The issue here (no pun intended) is that not allowing the vendor enough time to appropriately finish their work prior to bringing in the CxA for functional testing will often result in more deficiencies found. These deficiencies must then be documented, reviewed, discussed, and resolved through re-testing. (This warning flag is SO important and potentially impactful I have included two case studies).
It is important to get true buy-in from all parties and set realistic goals in relation to scheduling early in the project and carefully consider the consequences that compressing an already fast track schedule can have. Anytime it is tempting to condense the project schedule, review the potential implications with all stakeholders and consider if it might really be faster to go slower. To deliver a project on time, it is important to keep a foot on the gas, but also to remember the brakes are there too for when issues arise. Finding the right speed limit for your project may not only help to improve the quality of the deliverable but may also have positive impacts on overall team safety, morale, project cost, and may even get you over the project finish line earlier!
