MAN-7 WASTE MANAGEMENT

Technical Clarification

Clean building rubble

MAN7-T-OB1-1480

Guidance

2016-06-24

 

The GBCSA confirm that the use of ‘clean’ building rubble to fill quarries is deemed to be an acceptable means of re-use, and therefore an acceptable means of diversion from landfill for the purposes of credit Man 7: Waste Management.

Project teams are to demonstrate that the building rubble is ‘çlean’ in terms of demonstrating that the waste will not pose any environmental risk in the future. The project teams are to provide written confirmation that the waste is compliant with the requirements of the   NATIONAL ENVIRONMENTAL MANAGEMENT: WASTE ACT, 2008 (ACT NO. 59 OF 2008) and all sub-referenced standards to demonstrate this. In addition the waste management service is to confirm that all necessary assessments and permitting of the quarry in question have been duly completed and approved for the purposes of rehabilitation.

Waste Management Plan

Credit Interpretation Request Number
MAN7-T-OB1-781

Ruling
2014-04-14

The project team’s proposal to submit existing quarterly reports issued to the building owner from the 1st and 2nd quarter of the project’s construction programme along with a confirmation letter from the Contractor confirming commitment to continue to issue quarterly reports through the full construction period of the project is approved. The GBCSA note that this documentation is submitted in lieu of contract/specification requirements for quarterly reports to be provided to the owner.

Technical Clarification

Construction rubble (e.g. crushed concrete) used to stabilise landfill sites

Technical Clarification Number
MAN7-T-OB1-658

Guidance
2013-10-02

The GBCSA confirm that the use of construction rubble on stabilising landfill sites is not acceptable in terms of diversion of waste for the Man-7 Waste Management credit.

The GBCSA note that whilst some uses of construction rubble at landfill facilities may replace virgin material typically used in construction (e.g. road construction), many of the uses relate to addition to the landfill itself, e.g. cover material etc.

The GBCSA note that the aim of the Man-7 credit is to minimise the environmental impact associated with landfill sites by reducing the amount of construction material contributing to these landfills. The use of construction rubble to stabilise landfills therefore does not align with this aim.

Guidance

Documentation Requirements, Documentation Description, Short Report, final sentence, remove and replace with “The short report must summarise and reference all receipts demonstrating the waste types, waste recipients, total amount (by mass) of waste and dates removed from site within a table. The actual appended receipts to verify the reporting methodology only need to be the very first and final waste removal receipt (with dates indicated), one waste receipt for each waste recipient and one receipt per waste type in order to justify the inputs into the summary within the short report. It is not necessary to append all receipts within the submission, provided that all receipts are however summarised within the short report.".

Technical Clarification

Project site's tar and sub-base layer as part of demolition and construction waste for reuse/recycling.

Technical Clarification Number
MAN7-T-OB1-0516

Guidance
2012-06-07

The GBCSA has determined that asphalt and sub-base used on a project site’s roads’ layerworks (incl car park(s)), can be considered in the scope of demolition and construction waste for the credit aim of Man-7. Therefore, it can be deemed to contribute towards the percentage (by mass) of all demolition and construction waste for reused / recycled waste.

Technical Clarification

Green Star SA: Contractual documents and Appendices

Technical Clarification Number
MAN7-T-OB1-460

Guidance
2012-05-17

The Extract(s) from the contract(s) document must contain the contract conditions between the contractor and either, the developer of the building, or the building owner, stipulating the full criteria for reuse/recycling of the stated proportion of construction and demolition waste.
It is acceptable that these conditions are contained in Appendices to the principal contract document, given that the conditions and the Appendices in which they are contained, are referenced in the principal contract document.

Demolition Waste Management
(REVISED from TC issued 2010-10-13)

Technical Clarification Number
MAN7-T-OB1-0109

Guidance
2012-01-20

Where demolition activity is undertaken on the project site within 2 years from the date of practical construction commencement (the date upon which the clean project site is handed over to the main contractor), the demolition waste generated throughout the scope of the whole demolition contract must be included in calculations demonstrating compliance with the credit criteria. Projects registered prior to the 13th October 2010 and projects where demolition commenced prior to the 13th October 2010 may elect to include or exclude the aforementioned requirements. Projects registered after the 13th October 2010 must comply with the aforementioned requirements unless demolition commenced prior to the 13th October 2010.

Technical Clarification

Volume to weight conversion

Technical Clarification Number
MAN7-T-OB1-0045

Guidance
2009-09-10

For any materials which are not listed in Table Man-7.2 of the Green Star SA - Office v1 Technical Manual, 'Densities to be assumed for different solid waste types,' project teams may submit their own densities along with accompanying calculations in their Green Star SA submission. Project teams must demonstrate how the density was arrived at and how calculations were done (incl. the starting point of assumed density of the material/ product). The density of some materials can vary widely depending on their composition and manufacture (e.g. concrete could include asphalt, gravel, or many other materials). Projects must also demonstrate that calculations have taken into account the difference between the density of the material in transport/ crushed form, rather than in solid form/ in situ.

Technical Clarification

Land Reclaimation

Technical Clarification Number
MAN7-T-OB1-0018

Guidance
2009-02-06

Land clearing debris and soil are not considered construction and demolition waste and are excluded from the calculations of Man-7. Other types of waste sent to land reclaimation and used as clean fill or foundation/road sub-base contribute to the reused or recycled material quantity for the credit.
