When people think about construction projects that go over budget or fall behind schedule, they often assume the problems started after work began. But in reality, many of the most expensive challenges can be traced back to decisions made long before the first shovel hits the ground.
Industry leaders across commercial construction and real estate consistently emphasize the importance of early planning, risk identification and project alignment. Successful projects are rarely the result of good luck. More often, they're the product of thoughtful preparation before construction ever begins.
For business owners, developers and franchise operators, understanding these common preconstruction mistakes can help reduce risk, improve project outcomes and create a stronger foundation for success.
Mistake #1: Waiting Too Long to Start Planning
One of the most common misconceptions in commercial construction is that planning begins once drawings are complete. But the truth is that many critical project decisions should be made months before construction starts. Site selection, permitting, utility coordination, budgeting and scheduling all require significant lead time. Starting these conversations early often provides greater flexibility and allows teams to identify challenges before they become costly problems.
Industry research continues to show that organizations are placing greater emphasis on proactive planning and long-term real estate strategy rather than reacting to immediate needs.
Mistake #2: Focusing on Construction Cost Instead of Total Project Cost
Many owners begin a project with a construction budget in mind. What sometimes gets overlooked is that construction costs represent only one piece of the larger puzzle. Site development, utilities, permitting, design fees, furniture, technology infrastructure and long-lead materials can all have a significant impact on overall costs.
Making decisions based solely on an initial construction number can lead to surprises later in the process. Instead, owners should focus on understanding the total project budget and how each decision may influence long-term value, operating costs and future flexibility.
Mistake #3: Not Involving a General Contractor Early Enough
It’s common for owners to wait until the design is nearly complete before engaging a commercial contractor. While that approach can work, it may also limit opportunities to improve efficiency and identify risks early.
Contractors can often provide valuable input during preconstruction, including:
Preliminary budgeting
Constructability reviews
Scheduling guidance
Material recommendations
Risk identification
Value engineering opportunities
Early collaboration between owners, designers and contractors can help align expectations and reduce costly revisions later in the process. Because of this, early coordination is becoming more important than ever, especially for increasingly complex commercial projects.
Mistake #4: Underestimating Permitting and Approval Timelines
Permitting is rarely the most exciting aspect of a project. However, it’s one of the most important. Approval timelines can vary significantly depending on project type, jurisdiction, site conditions and agency requirements. Owners who assume permits will be issued quickly may face unexpected delays before construction even begins.
Successful projects account for these timelines early and build realistic expectations into the overall project schedule. A realistic schedule is often more valuable than an optimistic one. Think of it this way: if you overestimate how long the permitting and approval process will take, you’ll just gain that time back if it’s early. But if you don’t leave enough time for the approval process, you can’t get that time back.
Mistake #5: Planning for Today Instead of Planning for Growth
The most successful businesses think beyond their immediate needs. As organizations grow, facilities often need to support additional employees, customers, inventory, equipment or operational requirements.
Commercial real estate and workplace research consistently points to the importance of flexibility and adaptability in long-term facility decisions. Businesses increasingly want environments that can evolve alongside changing operational needs.
Questions worth asking include:
Will this facility support future growth?
Is expansion possible?
Can the layout adapt as our business changes?
Will this investment still make sense five years from now?
Planning for tomorrow can help avoid expensive modifications down the road and give you the freedom to dream big for your company’s future.
Mistake #6: Overlooking Operational Impact
Construction projects don't happen in a vacuum. For many organizations, construction must occur while business operations continue. As a result, operational disruptions can affect customers, employees and revenue.
Considering issues such as customer access, parking, safety, business continuity and project phasing during preconstruction can help minimize disruptions and protect the overall customer experience.
Mistake #7: Choosing the Lowest Price Instead of the Best Value
Every owner wants to manage costs responsibly. However, selecting a contractor based solely on the lowest bid can sometimes create challenges later. Differences in scope, assumptions, project staffing, scheduling and risk management can significantly affect project outcomes. The lowest upfront number isn't always indicative of the lowest total cost.
A successful project requires evaluating experience, communication, planning processes and overall value in addition to price. The goal should be achieving the best outcome, not simply the lowest initial cost.
Great Projects Are Built Long Before Construction Starts
When people think about construction success, they often focus on what happens in the field. But the reality is that many of the most important project decisions are made long before crews arrive on site. Thoughtful planning, realistic budgeting, early collaboration and a clear understanding of business goals can help owners avoid many of the risks that lead to delays, change orders and unexpected costs.
At Great Southern Constructors, we've found that some of the best opportunities to create value occur during preconstruction. By identifying challenges early, aligning project goals and developing a clear plan from the start, owners can move into construction with greater confidence and fewer surprises.
