A professional builder is a general building work contractor who can put your whole project together. The builder will assume complete responsibility for the work contracted and give you a warranty once completed.
In other words, a professional builder’s role entails the following:

An extensive business network of suppliers, trades, installers and experts that they draw on as required for a construction project.

Understanding of the technical aspects of construction in detail and knowing how houses work. They can assess a construction project and explain what is involved, as well as identify potential problems and provide solutions.

Advice on the most suitable approach if a project requires design services, and recommendations for a design professional if needed. Some professional builders offer both design and construction services. Alternatively, some builders are experienced in working with architects or building designers.

Extensive knowledge of and experience using the latest products and materials. They keep up-to-date and can help clients make the selections that will work best for their project and budget.

Familiarity with the building and construction regulations and codes in your area and how the system works.

Consultation with you to determine the right budget for your project. They know through experience the cost of materials and labour and therefore are in the best position to offer realistic cost effective construction, to achieve your project goals.

The ability to organize and manage a project – scheduling workers, trades and delivery of materials; keeping track of expenses; maintaining a clean and safe work site; and minimizing the inconvenience to clients. When necessary, they know how to deal with the unexpected and the surprises that sometimes occur on a construction project.

Now that you are familiar with the role of a professional builder, your next concern should be how to become one so that you can quickly land yourself a job in Nigeria’s growing construction industry.
How to Become a Professional Builder in Nigeria

The building profession is just like any other profession in Nigeria. There is a big difference between having a career in the building industry and being a professional builder. The fact that you have a degree in Building, Civil Engineering or any other related course or the fact that you have been handling building contracts and jobs does not qualify you as a professional builder.

Just as being a practicing accountant of a firm or possessing a degree in Accounting doesn’t qualify you as a professional accountant until you become a Chartered Accountant with ICAN. A similar process is also required to become a professional builder in Nigeria.

So to land your dream job quickly in Nigeria’s growing construction industry, here’s how you can become a professional builder in Nigeria;

1. Get an Academic Qualification

Your first step is to obtain a relevant academic qualification by pursuing any building and construction related program from any Nigerian university or polytechnic either in the ND or HND categories.

According to the Nigerian Institute of Building [NIOB], the professional body responsible for certifying professional builders in Nigeria, at present there are over eleven (11) Universities offering B.Sc Building Programme and about twenty (20) Polytechnics offering National (ND) and Higher National Diploma (HND) Building programmes in Nigeria.
