Supply Chain Advice Pack: Project Management Understanding Design Intent On-Site

Introduction

Delivering successful retrofit projects relies not only on good design, but on how well that design is understood and delivered on site.Under the PAS framework; PAS 2035 defines the design, coordination and whole-house approach and PAS 2030 sets out the installation requirements, workmanship standards, and compliance criteria for measures on site. These standards are interdependent. PAS 2035 defines what should be achieved, while PAS 2030 ensures it is installed correctly in practice.
