Barriers to Quality

• Design related:

– largely intricate and impractical details, poor design

coordination and unrealistic specifications

• Procurement related:

– price and preference, not functionality (or quality)

– fraud and corruption, or “political interference”

– institutional barriers (inadequate procurement and/or

monitoring capacity)

– procurement and delivery model on complex projects

(“design by employer” model)

• Construction related:

– inability of contractor to deliver required quality

Summary

• Clients were neutral or dissatisfied with construction quality on 16% of projects

• 14% of projects had unacceptable levels of defect

• Contractors were neutral or dissatisfied with construction documentation on 22% of projects

• Key barriers include;

– client / client agent monitoring capability

– procurement capabilities & competence standards

– procurement based on price and preference, not functionality (or quality)

– matching capabilities to the requirements

– fraud and corruption

cidb Project Assessment Scheme:

contractor performance

cidb Act; Project Assessment Scheme

1) The Board must …. establish a best practice project

assessment scheme, based on the best practices identified by

the Board …..

2) After a date determined by the Minister … all construction

contracts above a prescribed tender value are subject to an

assessment ….. of compliance with best practice standards

and guidelines published by the Board

cidb Project Assessment Scheme

Enterprise Development (February 2013)

• cidb Standard for Developing Skills through

Infrastructure Contracts (August 2013)

• cidb Standard for Contractor Performance

Reports for use on Construction Works

– time, cost and quality management

– health and safety management

– management of site conditions

– management of subcontractors (including

payment)

CONQUAS®

• Construction Quality Assessment System

• Architectural works:

– floors

– internal walls

– ceilings

– doors

– windows

– components

– basic mechanical and electrical (M&E) fittings

CONQUAS®

• Walls meet at right-angles – not more than 4mm over 300mm

CONQUAS®

• No visible cracks from a distance of 1,5m

CONQUAS®

• No stain marks or any visible damage

CONQUAS®

• No hollow sound when tapped with a hard object

CONQUAS®

Summary

• Contractor Performance Reports provide for a uniform

assessment of a contractor’s performance:

– will be mandatory on public sector contracts from mid-2016

– will in time be available to clients for procurement purposes

• CONQUAS® is a simple and effective scheme to obtain a

consistent evaluation of quality:

– cidb is investigating introducing CONQUAS® for General

Building Class of Works

– included in Contractor Performance Reports

cidb Contractor Recognition Scheme:

towards functionality

CIDB Act

The Board must … establish a best practice contractor

recognition scheme which:

a) enables organs of state to manage risk on complex contracting

strategies

b) promotes contractor development
