Project Title:Research into Safety Audit in Small Construction Co. in Hong Kong Supervised by Dr. John HO Presented by Cecilia Fung
BACKGROUND the last governor commented the construction safety as deplorable in 1992 (Lam & Rowlinson 1997) the related public sectors made solutions mainly –Performance Auditing Scoring System (PASS) for Housing Department –site monitoring system for Building Department –pay-for-safety Scheme for Works Branch construction accidents still ranked at top over the past 5-yr. from 1993-1997
IMPORTANCE OF SAFETY AUDIT Belief: Safety Audit to review performance as a final step in H&S management control cycle can achieve success in H&S (HSE 1993) Availability: –Construction CHASE –International Safety Rating System –5-star Health and Safety Management System –SMA-CON –Independent Safety Audit System
LIMITATION OF SAFETY AUDIT May fail if: –inadequate or non-existent system of audit –the safety audit cannot identify the inadequacy –the safety audit gives a wrong indication of pass score –companies aim only at improving score rather than revealing improvement in safety (Booth 1997)
AIM: To evaluate the effectiveness of the safety audit as a final step to review performance in Health & Safety Management cycle in construction industry
OBJECTIVES: O 1 : To investigate how safety audit (ISAS) reflects the safety performance of small construction Co. O 2 : To identify the cause of problems and develop some control points to eliminate the problems O 3 : To develop a safety performance critical control Point Model to identify essential elements for safety audit O 4 : To illustrate the operation and function of the model as a sliding scale in the safety audit O 5 : To compare and evaluate the performance indicators of the proposed model and existing system as a final step to review H&S performance
O1O1 survey Interview with PM/ Expert O2O2 Literature review Sampling and analyzing by ANOVA To define the problem nature and common misunderstanding of the safety audit in the existing system To identify the relationship of safety score and weighing factor as well as the problem area in selecting performance indicator - safety elements in safety audit Project Objectives Approach/methods/ tools Outcomes
O3O3 HACCP O4O4 Sampling for testing HACCP with different weighing factors Example for testing a safety performance critical control Point Model to identify essential elements for safety audit a sliding scale for the safety audit to improve H&S performance Project Objectives Approach/methods/ tools Outcomes O5O5 System design software Result evaluation
KNOWLEDGE IMPORTANT TO COMPLETE THE PROJECT To understand the working principles of the ISAS in construction industry To review the performance indicator for the H&S researched by predecessor To familiar with the working principle and philosophy of the Hazard Analysis and Critical Control Point (HACCP) as advocated by the USA in 1973 to apply a nil-defect programme to the production of food for astronauts.
Q1 Do Preventative control measures exist? Yes Is control at this step necessary for safety? Is the step specifically designed to eliminate or reduce the likely occurrence of a hazard of an acceptable level? Could the identified hazard(s) occur in excess of acceptable level(s) or could these increase to unacceptable level? Not a CCPYes Modify steps in the process or work procedure No stopNoNot a CCP No Q2 yes Q3 Stop Yes No Will a subsequent step eliminate identified hazard(s) or reduce likely occurrence to acceptable level(s)? Not a CCP Stop No Critical Control Point (CCP) Q4 HACCP Decision Tree
ANTICIPATED PROBLEMS INCLUDE survey with insufficient number of small construction cos. to voluntarily participate the research samples may be affected by inteventing variables such as time, types and size of the target samples system design heavily relied on the software development the feasibility of HACCP into the field of H&S of construction industry
CHANCE OF SUCCESS There may be some chances of success as reviewed at the pilot study carried in November 1999 3 small construction cos. building 1 to 3 40-storey residential buildings under the Housing Department contract showed some encouraging results: –the pass score in the ISAS does not guarantee continuous H&S improvement over the past one-year audit report –the HACCP seems to be applicable in devising critical control point for H&S performance indicator for safety audit
EXPECTED OUTCOME SE1 SE2 SE3 SE12 SE13 SE14 The 14 safety elements are in parallel same weighing factor when average the average score for a passing grade SE1 SE2 SE4 SE5 SE3 SE6 SE7 SE8 SE9 SE10 SE11 SE12 SE13 SE14 Existing system Proposed model
