MRc2.1 / Construction 2.2: Construction Waste Management Waste Management (2 credits) (2 Points) Objective To divert construction and demolition waste from disposal in landfills and incinerators with a view of achieving 50-75% diversion for the project scope.

Objective MRc4: Recycled Content Content (2 credits) (2 Points) To use building materials with high recycled content with a view to achieving 20% recycled content by cost for the scope of work. Methodology and Systems Identify civil & architectural building materials (CSI Master Format 1995 division 2-10 only) cost. Focus on the high value items; need to have high recycled content (post consumer and pre-consumer) Refer to contract specification with regard to specification for related items to ensure compliance to project requirements including LEED requirements. Confirm availability of materials with procurement schedule. A preliminary cost base with the available BOQ. Exclude labour and MEP component to get the baseline. For consistency, we propose using the LEED default value of 0.45 (hardcost for CSI Master Format 1995 division 2-10 only)

MRc5: Regional Materials Materials (2 credits) (2 Points) Objective To use building materials with high regional content (both extracted and manufactured) with a view to achieving 20% regional content by cost for the scope of work. Methodology and Systems Identify civil & architectural building materials (CSI Master Format 1995 division 2-10 only) cost. Focus on the high value items; need to have high regional content. Refer to contract specification 1-? with regard to specification for related items to ensure compliance to all project requirements including LEED requirements. Confirm availability of materials with procurement schedule.

MRc6: Rapidly Renewable Materials (1 Point) Objective To use building materials with high rapidly renewable materials and achieve 2.5% rapidly renewable contents by cost as per LEED criteria for works within for the scope of work. Methodology and Systems Design team from Qatar Foundation to specify application and use of rapidly renewable materials. Identify and use rapidly renewable materials from the design documents in the project. Refer to contract specification 1-? with regard to specification for related items to ensure compliance to all project requirements including LEED requirements. Confirm availability of materials with procurement schedule.

Objective MRc7: Certified Wood Wood (1 Point) (1 Point) To use 50% wood-based materials and products certified by FSC by cost in the building materials for the scope of work..
