The Most Common Problems

Mistake 1: Not analyzing the foundation’s ground or soil

Structural security is a must when it comes down to any project’s success. It’s also one of the most expensive things to fix since whatever was built on top of it may be negatively impacted. This is why a firm foundation is important and also why you should know what you are on top of- quite literally. Details like pipelines, sewage, and other obstacles can be disrupted or destroyed if proper procedure is not taken. Fixing issues below your project can also come out of your pocket if the proper permits and inspections were not done.

Mistake 2: Miscommunication between client and company

Sometimes miscommunication happens between people. When it’s between a company and a client, it can be very difficult to see eye to eye, which costs both parties extensive resources. Establishing expectations in writing can be a simple way to overcome this problem. Also, do not be afraid to voice your opinion. Customers must communicate the quality they have received, and companies, in turn, have a responsibility to ensure clear communication so that customer expectations align reasonably with the price paid. As the information a company gives creates the consumer’s decision, it’s important to be upfront with costs and estimates as well.

Mistake 3: Using unskilled laborers without proper supervision

Whether it’s newbies in training or outsourcing individuals to join a crew, these people are sometimes engaging in a new endeavor or trying something for the very first time.Supervisors and managers must ensure that skilled workers are assigned to work with new employees, or that proper training is provided to those unfamiliar with a project. This emphasizes the necessity of adequate oversight and instruction. Good managers and supervisors should be detail oriented with all facets of the project to make sure everything is completed in a safe and professional way. Without the necessary advising, projects can go awry. Some examples may be a measurement being wrong, a safety precaution not being followed, and workplace injury due to improper use of tools.

Mistake 4: Using cheaper or questionable materials

The cost of construction materials is a major factor, influenced by the material type, quality, source of purchase, and associated transportation expenses. Buying in bulk can help, but realistically for a small project, that might not be needed. Still, contractors must ensure the product is up to par and installed in a way that guarantees quality. Contractors and customers should be wary of faulty materials, which can be hefty to replace if the company says they aren’t at fault. A good rule of thumb: if a price seems too low for what they are promising, it’s probably too good to be true.

Mistake 5: Rushing through pre-construction

Skipping any step during the pre-construction phase is ill-advised, as it involves many critical components. From blueprints to selection of finer features, making a clear plan that covers everything is a necessity for a project. A good contractor or designer should be able and willing to walk a customer through the steps needed to complete their future project. Furthermore, meticulous design completion ensures seamless implementation, eliminating potential issues with measurements or the final outcome. Anticipation on the consumer’s end can also be a driving factor that might make you more susceptible to rushing in, but as the Aesop’s fable goes, slow and steady wins the race. Making sure every detail is accounted for can be the best investment of time into your project.

Mistake 6: Not budgeting enough

Being realistic, staying up to date on prices, and having a ballpark in mind can save your time and money. Some expenses can cost more than anticipated, an issue could pop up that stalls the project, or there could be events that are completely out of your control. Inflation is real and can be a big problem if it’s not considered within the first few stages. Labor is also a potential cost that could surprise consumers but needs proper funding so your project is completed. By feasibly planning for your project’s budget, there’s less margin for error and you won’t be caught off guard by any surprises.

Mistake 7: Not following safety guidelines

Jobsite safety is paramount and requires a commitment from every individual working on the project. Following OSHA’s guidelines and other safety policies can be the difference between someone getting hurt or someone successfully finishing a project. Those with extensive construction experience often fall into a common trap: relying on past successes with less safe methods and consequently overlooking the need to adopt more complex, safer processes. Most often, these are the very people who suffer greatly from one error, because they never consider that they are vulnerable to such a mistake. OSHA's strict enforcement really emphasizes how important it is to keep employees safe, especially those in dangerous jobs. If you are ever concerned, please visit OSHA online to look at their policies.

Crisis Management Top Takeaways

These following four suggestions for how to implement the project are crucial, so we think they deserve special attention. Whether you are figuring out an addition for the first time or are a remodeler, take these into consideration for a smoother process.

Do your research

No matter where you are in your vision, looking into the information you need can help you be informed. You might search on Google, ask industry professionals for advice, or connect with someone on social media who has completed a similar project. By coming to the table prepared to have an open conversation with topics you are familiar with, you save yourself time and effort in the long run. It also offers the ability to pose intelligent questions, allowing you to derive further benefit from the responses you receive.

Take your time in the planning stages

Be the person with a plan and invest in it. By putting in the time before the project starts, you can minimize potential issues and ensure you are bringing something meaningful to the professionals meant to help fulfill your vision. You don’t have to be technical, and that is certainly something their team can help you with, but having a basic idea of what you want is more helpful than you might realize. By using your team's expertise in the planning phase, you will proactively avoid complications later on.

Communicate your expectations clearly

When you are negotiating terms with another party, your thoughts and boundaries should be considered. Tell them exactly what you are hoping for, what you are willing to compromise on, and discuss the benefits for both parties. This allows for a quick comparison to determine if your expectations align. When they match, you can feel secure in having a company that will satisfy your requirements and create what you pay for. Make sure any additions or amendments added are signed by all parties involved.

Don’t settle for average

If you are displeased with any part of the process you need to speak up for yourself. Make sure you speak up about changes or alternative solutions now. This will prevent you from regretting the final outcome of the project. If a waiter gave you the wrong food, would you really tolerate that? That’s a similar situation for construction, but on a much larger scale and a larger financial investment. As a consumer, you should receive what you pay for. As a company, they should take pride in the work completed. Both parties should be able to maintain their ideals without compromise.
