National Examinations — 07-Bld-A3, May 2019 — Construction Engineering. Closed book; candidates may use one of the two approved calculators (Casio or Sharp). The paper prints seven questions of equal value (20 marks each) and states that any five questions constitute a complete paper, only the first five appearing in the answer book being marked. Candidates are urged to record any interpretive assumptions with their answers. All seven questions are worked below, because the set is intended as a study resource rather than as a single exam sitting.
