The news follows a detailed consultation with NFB members, which took place at the end of 2008.
A spokesman for the NFB said: “In a challenging economic climate we believe that this decision gives us the best possible platform for growth and we look forward to continuing to work with industry partners as well as forging new relationships during 2009.
“The NFB remains a strong and independent trade organisation committed to providing the best possible service and benefits to its members."
At the end of 2009 the Construction Confederation will only be left with two members - the Civil Engineering Contractors Association and Scottish Building.
The British Woodworking Federation will also terminate its membership at the end of the year.
Former Construction Confederation members the Major Contractors Group and the National Contractors Federation will dissolve at the end of the year to form the new UK Contractors Group which will sit outside the Construction Confederation.
