Recommendation Recommendation a) Review the joint list of project submissions for architects and engineers as agreed by the two professional boards, Board of Architects and Board of Engineers, providing clear lines of authority and responsibility between architects and engineers in respect of designs involving structural elements. a) Selection of contractor for complex works should be based strictly on the contractor’s experience, support of skilled technical staff and financial standing. b) PEs must have a minimum number of years of relevant experience (e.g. in engineering consultancy services) before being allowed to act as a Submitting Person for structural plans to the Local Authority. - select consultant based on Quality Based Selection (QBS) process such as International Federation of Consulting Engineers’ (FIDIC) guidelines to ensure that only competent consultants with relevant experience are selected. - Design of complex structures or geotechnical works must be vetted by accredited checkers registered with BEM. c) Review UBBL to require submission of structural plans to be accompanied by a soil investigation and geotechnical report by PEs with relevant geotechnical engineering experience for works in a geotechnical setting. d) Take stern action against any PEs who practice beyond the field of engineering that they are competent in. Procurement Process Stage b) Costing should be included into the ‘Preliminaries -’ of the contract for the cost of ensuring safety and complying with the provisions of the Occupational and Safety Act 514 (OSHA), Factory and Machinery, Act 139 and the Rules on requirements on Site Safety Supervisors under Factories and Machinery (Building Operators and Works of Engineering Construction) (Safety) 1986. Construction Stage a) Incompetent Clerk of Works as a Site Supervisor or Inspector of Works A Clerk of Works (COW) was formerly engaged for construction work to act on behalf of either the consultant or contractor. There were several cases of failures that were attributed to the incompetency of supervisors. CIDB now registers them as Site Supervisor (SS) and BEM registers them as Inspector of Works (IOW). Since engineers cannot be on site full time for most projects, it is therefore important that an SS or IOW possesses the right competency to undertake the task to ensure structures are constructed according to plans and engineering principles. Some developers second their office staff who might not be qualified to act as an IOW nor have sufficient time for site supervision. a) Incompetent and inexperienced contractors b) Insufficient Site Supervisors As contractors are the persons who actually carry out the construction works, it is important that they are qualified to handle the job depending on its complexity. There are prevailing requirements for the registration of contractors depending on their classification by CIDB. However, in practice, many contractors do not seem to possess the necessary qualifications and experience as evident by the number of structural failures due to contractor negligence since the consulting engineer cannot be on site full time. It is common for Government projects to be supervised by a skeleton strength of SSs. The case of structural failures at SM Majidee Johor Bahru in 1988 points to the lack of supervision where a technician had to supervise four schools under the ‘Projek Segara‘ scheme and concreting was allowed at night. During the investigation by JKR HQ, for a similar project across the Causeway, a Jurong Town Corporation housing flats in Jurong had allocated four technicians for a single project. 29
