  1. Project Title: Research into Safety Audit in Small Construction Co. in Hong KongSupervised by Dr. John HOPresented by Cecilia Fung

  2. 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

  3. 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

  4. 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)

  5. AIM:To evaluate the effectiveness of the safety audit as a final step to review performance in Health & Safety Management cycle in construction industry

  6. OBJECTIVES: • O1: To investigate how safety audit (ISAS) reflects the safety performance of small construction Co. • O2: To identify the cause of problems and develop some control points to eliminate the problems • O3: To develop a safety performance critical control Point Model to identify essential elements for safety audit • O4: To illustrate the operation and function of the model as a sliding scale in the safety audit • O5: To compare and evaluate the performance indicators of the proposed model and existing system as a final step to review H&S performance

  7. Project Objectives Approach/methods/tools Outcomes To define the problem nature and common misunderstanding of the safety audit in the existing system survey O1 Interview with PM/ Expert 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 Literature review O2 Sampling and analyzing by ANOVA

  8. Project Objectives Approach/methods/tools Outcomes a safety performance critical control Point Model to identify essential elements for safety audit O3 HACCP Sampling for testing HACCP with different weighing factors a sliding scale for the safety audit to improve H&S performance O4 System design Example for testing O5 Result evaluation software

  9. 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.

  10. HACCP Decision Tree Do Preventative control measures exist? Q1 No Modify steps in the process or work procedure Yes Is control at this step necessary for safety? Yes No Not a CCP stop Is the step specifically designed to eliminate or reduce the likely occurrence of a hazard of an acceptable level? yes Q2 No Could the identified hazard(s) occur in excess of acceptable level(s) or could these increase to unacceptable level? Q3 Yes No Not a CCP Stop Will a subsequent step eliminate identified hazard(s) or reduce likely occurrence to acceptable level(s)? Q4 Yes Critical Control Point (CCP) No Not a CCP Stop

  11. 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

  12. 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

  13. Existing system EXPECTED OUTCOME SE1 SE2 SE4 SE5 Proposed model SE1 SE2 SE3 SE3 The 14 safety elements are in parallel same weighing factor when average the average score for a passing grade SE3 SE6 SE7 SE8 SE9 SE10 SE12 SE13 SE14 SE11 SE12 SE13 SE14
