If you are considering a new building or major renovation in 2024, you may already be behind schedule. In fact, completing construction in 2025 could also prove difficult. Lead times for structural materials, mechanical equipment, electrical gear, and many other critical building components have increased dramatically since 2020. The global pandemic and conflicts in Europe, the Middle East, and Asia have all negatively affected lead times for material goods.
For example, the following key building components currently have lead times as follows (as of this publication):
- Pad-mount service transformers, 110–130 weeks
- Generators (100+ kilowatts), 36–48 weeks
- Low-voltage draw-out switchgear, 70–80 weeks
- Automatic transfer switch, 45–80 weeks
- Boilers (gas or electric), 10–50 weeks
- VAV and DOAS air handling systems, 10–20 weeks
- Rooftop air handlers (25+ tons), 20–40 weeks
These are only a sampling of the more extreme lead times, but they represent building components that can cause significant project delays if the procurement process is not properly managed.
So, what can you do about it? The answer depends largely on your project requirements and team structure. If a component, such as an air handler, has a lead time that slightly exceeds your desired construction schedule, consider pre-purchasing the unit. In other words, order the unit directly from the factory distributor instead of waiting for the mechanical contractor to do so. This strategy can save four to eight weeks in submittal processing time, but it also transfers the associated risks to the owner should issues arise.
If you require equipment with an even longer lead time, such as a service transformer, you may want to consider a temporary solution using a refurbished transformer. Due to supply chain challenges over the past four years, a growing market has emerged for reconditioned transformers. These units are tested and often come with guarantees sufficient to bridge the gap until a new permanent transformer arrives. Of course, this market is also beginning to experience shortages, so it is important to confirm whether this strategy is appropriate for your project.
Large generators also currently have extended lead times, and some generator types are not available at all. To help alleviate scheduling challenges, renting a portable generator for a few months may provide a practical temporary solution. The National Electrical Code (NEC) now requires provisions for connecting portable generators, so why not use that requirement to your advantage? However, as with many similar markets, portable generators are experiencing higher-than-normal demand, and securing one for your project may prove more challenging than anticipated.
Like anything else, project success ultimately comes down to proper planning. Accounting for current lead times in your construction schedule can help alleviate much of the pressure commonly experienced as projects near completion.
