Johannesburg - Construction workers in the Western Cape marched to the Building Industry Bargaining Council (BIBC) in Cape Town demanding higher wages on Wednesday.
The march by members of the National Union of Mineworkers (NUM) started on Robert Sobukwe Road, NUM regional spokesperson Benson Ngqentsu said.
The workers were due to hand over a memorandum to BIBC officials.
In a statement, the BIBC said it received a notice on Tuesday from the NUM about the march.
"They requested someone to be available to receive their memorandum but did not indicate the reason for the march," it said.
Construction workers downed tools on Monday demanding a 13% wage increase.
The SA Federation of Civil Engineering Contractors (Safcec) - which represents employers - tabled a 7.5% offer, which was rejected.
