Company Background

Incorporated in 1998, Putrajaya

Perdana Berhad is an investment

holding company and is recognised

as one of Malaysia ’ s most

innovative and reliable construction

groups.

It has successfully delivered several

prominent award winning and large

scale projects on a turnkey design-

and-build basis as well as pioneering

energy efficiency in construction.

PPB’s Green Efforts

We have always held this beliefthat putting a stop to globalwarming and climate change isjust as important as ensuring ahealthy bottom line. In the withthis, we have since 2002, made acommitment to ensure energyefficiency, and now, green in ourprojects.

List of Green Buildings undertaken by PPB

PPB is the LEADER in Designing & Constructing Energy Efficient & Green Buildings.

1. We built the LEO (Low Energy Office) Building for the

Ministry of Energy, Green Technology & Water

(KeTTHA), a 2006 ASEAN Energy Award Winner

3. We built the HQ for Suruhanjaya Tenaga, a Green Mark

and GBI Platinum certified building.

2012 : ASEAN Energy Award Winner

2012 : Emerson Cup for India & SEA (Champion)

2013 : ASHRAE Technology Award (2nd Place)

2013 : Green Apple Award

Energy Policy Maker

Energy Sector Regulator

ENERGY EFFICIENT & GREEN BUILDINGS

2. We built the GEO (Green Energy Office Building)

(formerly known as ZEO) for Pusat Tenaga Malaysia

(PTM).

GEO is Malaysia’s 1st GBI certified green building

• Develop a strategy to reduce and manage

waste

• Assign a Coordinator to implement, monitor

& report

• Identify & estimate the types of waste (

think of reducing waste measures, reuse and

recycle)

• Provide method statement for segregation

of waste during construction.

• Provide list of construction haulers and

recyclers to redirect waste.

• Indentify handling & transportation

procedures

Challenges of implementing Construction Waste Management

Challenges of implementing construction waste management

Challenges Action Plan

Lack of education & awareness • Training on awareness on staff and site team

Upfront cost • Allow in tender budget

• Cost savings from better managing the material

supply/storage & recovery/disposal

Insufficient environmental officer • Training

• Appoint a designated person

Challenges of implementing construction waste management

Challenges Action Plan

Resistance to change to adopt the

eco-friendly construction practices

• Company policy and objectives

• Sub contractual requirement

•3Rs•ISO 14001

Challenges of implementing construction waste management

Challenges Action Plan

All relevant requirements for the specific ratings of Green Buildings shall be complied

• Adopt the GBI guideline : provide dedicated areas where on

site sorted waste material can be stored for recycling

• Adopt the GBI guideline : Recycle and/or salvage ≥ 50% (75% for 2 points) volume of non-hazardous construction debris.

Challenges of implementing construction waste management

Challenges Action Plan

Limited space to provide waste bin for segregation

• Early planning i.e. put into the PQHSE Plan

Sourcing waste contractors • Preplanning

Ditto recyclers e.g.. Some manufacturer s refuse to take back timber pallet

• Establish the contractual agreement

• Carry out 3R effort internally

Handling, monitoring & recording • Have standard CWMP & work instructions

/ practices and reports.

Sample of GBI Report by Contractor

•Waste Disposal

- 3Rs: reduce, reuse & recycle.

During Construction

Dedicated area and storage

for collection of non-

hazardous materials for

recycling. Make

arrangement with licensed

waste collector to provide

segregation bins for metal,

tiles, timber, concrete,

glass, bricks and plastic.

Challenges of implementing Construction Waste Management

GREEN PRACTICES: Calculating Construction Waste

Calculations

1. Calculations are based on the amount of waste diverted from landfill or

incineration compared with the total amount of generated waste at site.

2. Convert all materials to either weight or volume to calculate the

percentage. Exclude excavated soil and land clearing debris.

3. Hazardous materials should be excluded from calculations and should be

disposed of accordingly to relevant regulations

GREEN PRACTICES: Calculating Construction Waste

Material Density (lbs/cy) Density (kg/m3)

Steel 1,000 590

Wood/timber 300 180

Rubble 1,400 830

Mixed Waste 350 210

Cardboard 100 60
