Jason is responsive, cooperative and able to insert the role into the design team structure, and keen to prove the value of an independent overseer who understands well the workings of a design team and the weight of duty carried by each person.

Site Inspection


The PDBR role involves site meetings but inspections are outside of the responsibility which is limited to ensuring and finally declaring that the design alone is compliant with the building regulations.



As a testimony of competence through witnessing the build process, the gallery below evidences Jason’s site experience in the CDM2015 role as principal designer, and carrying out inspections through being novated and working together with a contractor to address design issues that at times require quickfire solutions, stakeholder agreement, and swift actions towards implementation.
