Overview

The correct remediation process is quite different to any other architectural or construction process that has been developed in the construction industry to date. The challenges these failing structures present to the individual professionals (building surveyor, designer, builder and quantity surveyor) are quite unique. These challenges require a learned experience in risk management, liability management and strategy planning.

Behind these initial higher level filters we must then have an intimate and superior understanding of …

• the common failures of current marketed products and processes
• the common failures of historical marketed products and processes
• past and present codes and standards
• the Weathertight Homes Resolution Service's (WHRS) policies and processes
• the Department of Building and Housing's policies and processes
• the legal, evidential and information gathering processes
• lateral remedial design, risk assessment and risk management processes
• the performance aspects of water and the effects of wind speed and wind pressure
• performance aspects of developed alternative solutions
• other team members' professional responsibilities, liabilities and processes
• the confidence and skill to drive specific documentation and solutions through local government institutions and contracted certifying consultants

 

Due to the recession and fall of new construction numbers there has been an exodus of designers and trade professionals from the regular construction industry into the specialist field of remediation. Consequently, the lack of experience and knowledge base for remedial design and the unsuitably skilled workforce is becoming alarmingly obvious. We are already seeing the results of this and history is repeating itself with secondary failures of recently 'remediated' buildings.

 

A successful remediation process involves a small group of professionals working together towards a common goal. This will typically involve a client, a registered building surveyor, a remedial designer, a quantity surveyor and a building company. Needless to say, all members of the team must have remedial design experience to effectively contribute to a fast and efficient process. It is important that while all team members individually contribute to the process we also work within the scope of our expertise, qualifications and insurance. Too often we see remediation processes that involve individuals stepping outside of their own area of expertise, creating additional risk and added liabilities.

 

With good teamwork, communication, research, assessment, detailing and workmanship the results will be weathertight solutions and structures that will perform well in excess of the 50 years required from the NZ Building Code.
