Ten years ago, you could walk onto just about any job site and you would see the same thing: the electrical contractor was coming in with the construction drawings at 65%, pricing was tight and the schedule was already starting to slip. Crews were focusing on getting material on-site and figuring out how to make the design fit the building. Electrical contractors made it work, but it was reactive. Requests for information (RFI) stacked up, and field coordination only happened after a problem came up. 

Compare this to a job where preconstruction and planning is implemented before boots ever hit the ground. The electrical contractor sits in preconstruction meetings months before mobilization. The general contractor and engineers review one-line diagrams earlier in the design where changes are still easy to make. Equipment with a long lead time is identified before it becomes a scheduling problem, and layout decisions are happening before concrete gets poured. The atmosphere of the job shifts right away.

This is not a pipe dream. You are seeing it on large projects being built right now. A number of things occurred to shift projects in this direction. Lead times for major gear have stretched out. Labor is harder to find and more challenging to predict. Schedules keep tightening up, all while electrical scope is growing with controls, data and building systems layered into everything. The old design-bid-build approach is struggling to keep up. 

When electrical contractors come in late, most decisions are already made. At that point, the job turns into execution under constraint instead of planning with intent. When the EC is brought in early, the entire dynamic of the project can change. They are no longer reacting to decisions; they help make them. That difference shows up in schedule reliability, cost control and number of submitted RFIs. 

The old model: Reactive electrical contracting

For anyone who has ever run a ground-up project, this will sound familiar. Contract drawings go out at 50%, the job gets bid and awarded, specifications get vetted and the RFI process begins—all before coordination has even begun. 

One of the first issues that arises is in the electrical room. An electrician reviews the electrical room layout, compares site conditions to the drawings and realizes that the two do not match. Clearances are tight to begin with, all design panels are drawn 20 inches by 30 inches by 5 inches, and all transformers are drawn the same size regardless of the kilovolt-ampere size. Structural beams under the walls in the electrical room are in the way. Mechanical systems already took up space that looked available on the drawings since none of the conduit was shown. 

At this point, the electrical contractor’s field team becomes a problem-solving team. Crews reroute, the engineers revise, RFIs move through the system and updated drawings get released. Then, when the next issue arises, this process starts all over again. Every one of these steps costs time and money. The field isn’t where the problem starts—it’s where it finally becomes visible. By that point, the team is in reaction mode instead of planning, and the schedule takes the impact. 

Early engagement

Preconstruction is not showing up to a kickoff meeting, skimming drawings and having brief discussions about specifications. It is getting involved while the project is still taking shape, and having input in the beginning when design can still be adjusted. On many jobs, that starts six to eight months before boots hit the ground. Electrical contractors review design intent, sit in coordination planning, give suggestions on preferred installation methods and align with procurement strategy and schedule. A common scenario is a one-line review with the GC and engineer. The conversation goes beyond code, and it turns into a constructability review. Does the electrical room have proper spacing for routing of feeders? Is there enough room for the electrical equipment and clearances? Is there a better routing option, such as in slab or underground? Can we use a preferred list of materials that will improve prefab opportunities? 

During one of these kickoff meetings, a contractor said, “we are not pricing drawings anymore. We are helping shape them so they work in the field.” When electrical contractors get involved early, they bring their field experience into design. They spot routing conflicts, clearance and equipment issues, and routing problems while changes are still manageable. They also use these meetings to find opportunities to optimize prefabrication. These solutions reduce friction for the entire team. Fewer clashes mean fewer RFIs, better layouts improve installation and electrical room preplanning can reduce crowding and improve safety. 

Solving problems during coordination meetings means they do not have to get solved on lifts, creating bottlenecks during and causing schedule delays, which can trigger RFIs, putting areas on hold while waiting for responses. RFIs asked at the right time—before construction starts—are a good thing because they help with design improvements and clarification. RFIs during construction are not good. They cause delays and can affect scheduling at the most inopportune times, affecting staffing and materials delivery. 

Procurement as a preconstruction partner

Typically, procurement happens after the job has started and the team is mobilizing. Materials would get ordered and tracked against the schedule. With lead times currently what they are, this approach starts to negatively affect the schedule almost immediately.

Equipment with long lead items such as switchgear and transformers will often drive the schedule. If the contractor is waiting until construction to deal with those timelines, it creates risk and schedule delays that are hard to recover from. Early involvement changes that, as contractors can identify risks during design and raise flags for possible schedule impacts. If a piece of gear has a year-long lead time, the team can act. They are able to release early packages designing around electrical equipment availability or adjusting the design to what is available. This gives the team the ability of releasing gear months ahead of the normal timeline, and this single move can keep the project on schedule.

Prefabrication as a preconstruction partner

An electrical contractor can have the most advanced and efficient prefabrication shop in the country, but without the partnership and buy-in of the general contractor or the owner, it can mean absolutely nothing to the job site. You can have hundreds of prefab assemblies that have been coordinated and built, waiting to be delivered to the job site that become unusable, and it can cause unwanted rework due to one schedule change. The other parties will never know the impact of what they consider a minor adjustment. 

Being a contractor with partnership in mind means opening your prefab doors and showing the general contractor and owner what is at risk when they consider minor schedule changes. This gives them the ability to see that, if a schedule slips or adjusts all the prefab opportunities that possibly helped you win the job in the first place, it now become a negative impact due to installation challenges and logistics bottlenecks. With the electrical contractor and general contractor working together early during preconstruction, they can plan prefab while the design is still flexible, BIM models will support assembly planning, spool drawings and installation sequencing. The effect shows up quickly. 

Once construction starts, crews spend more time installing and less time fabricating in place. Work gets safer and quality stays consistent. Showing the GCs and owners what is at risk early, and getting them bought in to the prefabrication process, helps them understand that prefab starts at coordination and preconstruction rather than at scheduled delivery. This early involvement can change relationships, with electrical contractors helping to solve scheduling and construction issues before they hit the job site. This, in turn, builds trust with GCs and owners.

Shared involvement 

One piece of the partnership mentality that often gets overlooked is the connection between the field and office. Once the project gets started and technologies start to be implemented, the silos start to form. Contractors may not want to share information for fear of liability issues and to protect their installation processes and timelines. Working together with all trades can benefit the entire project. 

For example, if a mechanical contractor, EC and GC are all doing site mapping independently and not sharing the information, this can lead to bottlenecks. When shared, these can bring value to the project and make it successful for the entire team. Share this information because you want to. This goes a long way for the partnership mentality. The language then shifts and becomes less about dividing scope and more about shared outcomes.

Looking ahead

These partnerships are happening now. The large data centers are not being awarded on price alone. They are looking for contractors they have previous relationships with, including those that have been involved in previous projects and know the scheduling challenges and how to solve them. In general, these companies bring value to the table before and after construction has started. The most successful projects are seeing it now as teams align early, decisions are made that include the people who do the work, and problems are addressed before electricians hit the job site. Contractors are installing systems and helping define how the project gets delivered.
