Welcome to official WAEC Syllabus for Block Laying, Brick Laying And Concrete Works. We also include list of tools and recommended textbooks. This syllabus is drawn purposely for examination, hence the topics are not necessarily arranged in the order in which they should be taught.
Block Laying, Brick Laying And Concrete Works
There will be three papers, Papers 1, 2 and 3 all of which must be taken.Papers 1 and 2 shall be a composite paper to be taken at one sitting in 1 hour 45 minutes for 100 marks.
Paper 1: will consist of forty multiple-choice objective questions all of which are to be answered in 45 minutes for 40 marks.
Paper 2: will consist of five short-structured questions. Candidates will be required to answer any four in 1 hour for 60 marks.
Paper 3 will be a practical test of 3 hours duration for 100 marks. It will be a work
piece involving laying of a total number of blocks not exceeding 30 and where the work piece is made of bricks only, the total number of bricks shall not exceed 100.
Where the work piece to be laid is a combination of bricks and blocks, this will not contain more than 20 blocks and 40 bricks. (i.e. in composite walling).
A list of materials for the test shall be made available to schools not less than two weeks before the paper is taken for material procurement and relevant preparations.
Alternative to Practical Test
Alternatively, in the event that materials for the actual practical test cannot be acquired, the Council may consider testing theoretically, candidates’ level of acquisition of the practical skills prescribed in the syllabus. For this alternative test, there will be two compulsory questions to be answered in 3 hours for 100 marks.
