Understanding & Managing the Risks & Uncertainties (with Worked Examples)

» Qualified for 7 PDUs by PE Board


The construction cost estimating process is difficult and complex. Decisions have to be taken in the face of uncertainties relating to cost and quantities of production; the production period and foreseeable constructional problems. The difficulties in estimating are compounded in maintenance work due to the following distinguishing factors of the work:

- Small, generally non repetitive and multi-location jobs/tasks
– High labour content in the work; vulnerable to quality and productivity issues
– Higher material wastage due to small work parcels
– Little benefit of learning curve due to nature of work
– Lack of reliable cost standards and data to guide the estimator.

The higher ‘uncertainties’ in executing and managing maintenance work has led to higher variability in cost estimates. The variability is further amplified in maintenance tenders as contractors adopt different risk management approaches and commercial considerations in bid submission.

It is important that cost estimates are accurate. From an Owner’s viewpoint, the estimates form the basis of derivation of long life cycle budgets and shorter term budgets for work procurement. From a contractor’s viewpoint, the estimate will form the basis of a tender bid. For both Owners and Clients, the estimate forms the basis of approval of star rates for variations and non-standard work which often occurs in maintenance contracts.


The course will provide knowledge and skills to understand the:

  • Types of and Nature of Maintenance Work
  • Fundaments in Cost Estimating
  • Maintenance Cost Estimating: Managing the Risks and Uncertainty
  • Long Term Maintenance Cost Estimates
  • Medium and Short Term Maintenance Cost Estimates
  • Estimating Spot Items and Star Rates in Maintenance Work.

Dr Quah Lee Kiang FRICS

Dr Quah is the Director of the Real Estate & Construction Centre and the Real Estate & Construction Academy in Singapore. She has extensive regional and international experience in Project and Facilities Management & Maintenance research, advice and academia.

Dr Quah led the EU funded project BE4213 Condition Assessment and Maintenance Strategies for Buildings and Building Components, which among other things, sought to develop an objective building condition assessment system. This project formed part of ongoing research over the last 20 years which culminated in Dutch Standard NEN 2767 on Condition Assessment of Buildings, believed to be a ‘world first’.

Dr Quah’s professional and research affiliations include being Coordinator of the International Council for Research and Innovation in Building and Construction (CIB) Working Commission 70 on Facilities Management and Maintenance for a decade and past President of the Chartered Institute of Building Singapore Centre.  She was also a member of the Royal Institution of Chartered Surveyors (RICS) Asia Board, Singapore Board and Asia Pacific Sustainability Board.

Dr Quah was conferred an Honorary Fellow by Oxford Brookes University for her work in real estate and construction education and the unusual impact her career has had on this particular academic field in Asia.
