Advice Pack The PAS2035 stages - Stage five – Construction Coordination

Construction Coordination in the PAS2035 process

In the PAS 2035 process, construction coordination involves overseeing and managing the implementation of retrofit measures to ensure they meet the specified standards and requirements. This role is typically handled by a Retrofit Coordinator. Construction coordination is the fifth stage of the PAS2035 process:

1. Preliminary work
2. Retrofit assessment
3. Pre-stage coordination
4. Planning permission
5. Construction coordination
6. Post-stage coordination

Engage with installers

The first step is to engage with installers who might carry out the proposed retrofit works. For each part of the retrofit works, you should obtain multiple quotes from installers to ensure the best quality and value.

Some key considerations when engaging with installers are:

• Early engagement: involve installers early in the planning process, allowing them to provide input on project scope, realistic timelines, and potential challenges.
• Clear communication: maintain open and clear communication throughout the project. Regular meetings and updates help keep everyone on the same page and address any issues promptly.
• Certified and registered installers: work with certified installers who are PAS 2030 certified and TrustMark registered (or equivalent). This ensures high- quality work, compliance with standards, and provides guarantees on installations.
• Detailed briefing: provide installers with detailed project briefs, including specifications, timelines and any constraints. This helps them understand the project requirements and expectations.
• Monitoring and support: regularly monitor the progress and provide support as needed. Address any issues or changes promptly to avoid delays and ensure the project stays on track.

Retrofit design validation

Retrofit design validation ensures that the planned works achieve the desired improvements in energy performance and environmental impact. It safeguards against poor design and confirms compliance with the PAS 2035 standards. The Retrofit Coordinator is responsible for this validation. If designs are not compliant, the Retrofit Coordinator collaborates with the Retrofit Designer to align the plans with the required standards.

RAMS review

Before any physical work begins, the Risk Assessment Method Statements (RAMS) review is conducted to identify potential risks and outline safe working practices. During the design phase, the Retrofit Coordinator ensures that the RAMS are aligned with the retrofit design. As the retrofit works are carried out, the RAMS are continuously reviewed and updated as necessary. This ensures that any new risks identified during the construction are managed effectively. Post-construction, the RAMS are reviewed to ensure that all safety measures were adhered to and to evaluate the effectiveness of the risk management strategies implemented.

Installation to PAS2030:2023

PAS2030 is the standard which focuses specifically on the installation process of retrofit processes. PAS2030 and PAS2035 have been designed to work in tandem. PAS2030 includes requirements on installation processes, process management and service provision.

PAS2030 registered installer have demonstrated their compliance with the requirements for installing energy-efficiency measures. Two of the key reasons that it is recommended that installers used are PAS2030 registered are:

• Access to funding: government-funded energy efficiency schemes require installers to be PAS2030 registered.
• Quality assurance: this certification ensures that installers follow best- practices, reducing the risk of poor workmanship.

Commissioning and project handover

In the PAS 2035 process, commissioning and project handover are critical stages that ensure the retrofit measures are correctly implemented and fully functional. Here’s a breakdown of each:

Commissioning

• Functional testing: Checking that all systems (e.g., heating, ventilation) are working correctly
• Performance verification: Ensuring that the installed measures achieve the expected energy savings and improvements
• Adjustments: Making any necessary adjustments to optimise performance

Project Handover

• Documentation: Providing detailed records of the installed measures, including manuals, warranties, and maintenance instructions.
• Training: Offering guidance to the building occupants on how to use and maintain the new systems effectively.
• Final Inspection: Conducting a final walkthrough to ensure everything is in order and addressing any last-minute issues.

Air testing/thermography

If air testing or thermography is part of the retrofit strategy, and a baseline test was conducted prior to any works, then this should be carried out prior to any works to ensure that targets have been met and there is no detriment caused by the works.

What happens next?

Following construction, post-stage coordination is the final stage in the PAS2035 process.
