Standards, guidance and reference documents provide an opportunity to clearly specify expectations around minimum levels of service, consolidate practical experience gained by the organisation and disseminate specific specialist knowledge relating to highway construction operation and maintenance so this knowledge can be applied efficiently and consistently across the organisation. In some cases we have designed specific tools to capture proven methodologies so they can be consistently and widely applied to state highway work.

In order to ensure value-for-money and consistent environmental impact assessment and mitigation across the state highway network, the Environment and Urban Design team works closely with project managers to collect best practices, identify relevant international trends and develop New Zealand specific standards, guidelines and tools.

In order for a new standard, guideline or reference document to be implemented, its purpose and content is scrutinised through a consultation and formal ratification process.

Environmental and social responsibility standard

The ESR Standard tells you what you need to do at each project phase from programme business base through to operation and maintenance. The ESR Standard is a practical application of legal requirements within state highway activities. The ESR Standard should be referenced in contract documents.

Environmental and social responsibility standard (ESR Standard)

Assessment and design guidance and tools

Use these to help you follow and achieve the ESR Standard. Guidelines contain recommended good practice suitable for use on state highways and become legally binding when invoked in contract documents. Use these documents when improving, operating or maintaining the state highway network.

Refer to guidelines in contract documents where relevant.

Impact assessment during early stages of project development

The ESR Screen is an important tool to help identify the environmental and social issues and risks at the early stages of project development.

Environmental and social risk management

Use it as early as possible in project development but as a minimum complete during the indicative business case. Find the screen and supporting information here. The ESR Screen results will help with developing and applying mutli criteria analysis for options assessments.

Other specialist tools can be found under the tools section of HIP or in relevant technical disciplines pages.

Specifications and procurement

Specifications, also referred to as principal requirements or minimum requirements, when included in contracts are contractually binding. The specifications along with more specific project requirements contained in contractual documents set the minimum standards and requirements the Waka Kotahi expects in relation to the delivery of contracts related to state highway improvement (or maintenance) projects.

A list of all the standards, specifications, guidelines and reference documents which relate to environmental and social responsibility and are sponsored by the EUD team manager is contained in the HNO environmental and social responsibility manual. The standards, guidelines, tools and references included in this manual are applicable to all network capital works and maintenance operations.
