The GBCSA can confirm that the 20% less concrete and reinforcing steel (by mass) is a combined reduction and does not mean 20% less Concrete AND 20% less Rebar as separate items.
The GBCSA provide the following clarification relating to this issue: One of the following needs to take place:
(1) 20% less structural steel
OR
(2) 20% less concrete + reinforced steel
OR
(3) 20% less timber

This Technical Clarification is applicable to Mat-3 Reused Materials, Mat-6 Steel, Mat-7 PVC Minimisation, Mat-8 Sustainable Timber, Mat-9 Design for Disassembly, Mat-10 Dematerialisation and Mat-11 Local Sourcing.
Where the ‘Documentation Requirements’ (for Design and As Built) request a ‘Short report’ and a ‘Quantity Surveyor report’, if the ‘Short report’ is prepared by the Quantity Surveyor, it is permitted that one consolidated report satisfying both ‘Documentation Requirements’ be submitted instead of two separate documents.
Where the ‘Short report’ is not prepared by the Quantity Surveyor (e.g. green building consultant, Accredited Professional, structural engineer etc.), both the ‘Short report’ and ‘Quantity Surveyor report’ must be submitted independently.
The purpose of the ‘Quantity Surveyor report’ is to validate data (e.g. quantities, costs, Project’s contract value etc.) referenced within the ‘Short report’.

Roof hardscape

Guidance

A roof garden consists of vegetated area. If there is a patio area for use by occupants or serving another purpose, the project team may submit documentation demonstrating a dual purpose. It is important that the roof cladding has not simply been replaced by another material but that the other material serves a second function not typically served by roofing. Assessors will evaluate projects against the credit aim of reducing the total amount of material used.
