  2. DEFINE PHASE

  3. DEFINE PROJECT CHARTER Business Case The field offices and staging area of construction waste for Special Capital Budget Projects (SCBP) is located in the tennis court parking and each project is allocated with 200 m2 of space. This year, there are 4 projects to be implemented which will generate significant volume of waste. Parking space is a valuable resource and requirement is increasing to accommodate the staff growth in line with Strategy 2020. With the SCBP being implemented concurrently requiring a significant amount of space for the respective staging areas, the increasing demand for more parking slots and the heightened awareness on environmental safety hazards, disposal guidelines and procedure for construction waste should be reviewed.

  4. DEFINE PROJECT CHARTER Business Case Location of Field Offices and Staging Area Site Development Plan of the ADB Headquarters

  5. Legend: Circulation • No. of parking slots = 49 • with 2 Contractors at a time: • Usable parking slots = 27 Contractor 1 (200 m2) Circulation Contractor 2 (200 m2) DEFINE PROJECT CHARTER Business Case

  6. DEFINE PROJECT CHARTER Problem Statement • Based on the disposal requests filed for the SCBP from 2005-2007, it takes an average of 13 days to dispose construction waste which resulted in the following: • accumulation of waste in the staging area • encroachment to parking slots • creates an eyesore and is a potential • hazard.

  11. DEFINE PROJECT CHARTER Cost Implication A parking slot costs Php2,900 per month Assuming there will be 50% overspill per project or 8 parking slots = 8 x Php2,900 = Php23,200 per month Multiplied by 4 projects: Php92,800 or ≈ US$2,000/month or US$24,000 annually

  12. DEFINE PROJECT CHARTER Goal Statements 1. Review the guidelines and procedure for the disposal of construction waste to ensure a faster turn around time and a cost effective utilization of space. 2. Include this process as part of the EHSMS resource conservation program on waste generation/reduction and recovery.

  13. DEFINE PROJECT CHARTER Project Scope Construction Recyclable Waste (HMR) Reusable Asset (ADB) Construction Debris Wood scrap (wood planks, wood shavings) Metal scrap (disassembled ducting and trusses) Defective Equipment Obsolete Equipment Water Closet Lavatory Damaged lighting fixtures Doors and jamb Glass panel Locksets Lighting fixtures Kitchen Equipment Mechanical Equipment

  14. DEFINE PROJECT CHARTER SCBP to be covered This project will focus on the disposal procedures for the following SCBP: • Rehabilitation of the Building Facade and Roof Deck Project; and • Rehabilitation of the ADB Cafeteria and Kitchen Facilities Project.

  15. DEFINE SIPOC DIAGRAM Project Manager notifies Senior Engineering Officer on items for appraisal and disposal SEO sends email to OAFA-AB; OAFA-AB staff advises Project Manager to fill-up form OAFA-AB processes and approves request Disposal activity

  19. MEASURE PHASE

  20. MEASURE OPERATIONAL DEFINITIONS Recyclable Waste: materials that are not needed by ADB but can still be used by another entity. These items are hauled by a Service Provider. (ESAC Project) (MVAC Project)

  21. MEASURE OPERATIONAL DEFINITIONS Reusable Asset: materials that can still be reused by ADB. These items are retained for safekeeping and future use. Glass Panel Lighting Fixtures Furniture

  22. MEASURE OPERATIONAL DEFINITIONS Construction Debris: consists of unwanted materials produced directly or incidentally by construction/demolition activities. These are hauled by the Contractor as part of their project contract.

  23. MEASURE DATA COLLECTION • SCBP data available: • 1. Enhanced Security Access Controls to Bank Facilities (ESAC Project) • 2. Security Protection of Outside Air Intake for the Building Air-conditioning System (MVAC Project) • SCBP Job Orders from 2005 to 2007. • Collected data was subjected to normality test, process capability, determine current sigma level and pareto chart of processing time variations.

  24. MEASURE DATA COLLECTION Job Orders 2005-2007 Job Orders with disposal processing time 14 days and above

  25. MEASURE DATA COLLECTION Job Orders 2005-2007

  43. Recyclable Waste Recyclable Waste

  44. IMPROVE PROPOSED GUIDELINES • 1. Design and Planning Phase • Maximum material recovery • Minimization of waste generated at source • 2. Bidding Phase • Waste Management Plan • 3. Implementation and Monitoring Phase • Construction practices that can prevent waste • Purchasing practices that will prevent waste • Waste classification and segregation • Waste collection, handling and storage • Waste recording, transfer and disposal 4. Post construction Phase

  45. IMPROVE PROPOSED GUIDELINES 1. Design and Planning Phase • 1.1 Design Phase • Design with standard sizes for building materials. • Specify materials and assemblies that can be easily disassembled/deconstructed at the end of their useful life. • Identify materials’ reusability at the end of their useful life. • Choose durable and non-toxic interior finishes or materials. • Design spaces to be flexible for changing uses. • Consider reusing materials (on-site).

  46. IMPROVE PROPOSED GUIDELINES 1. Design and Planning Phase • 1.2 Planning Phase • Survey the site and identify reusable assets and recyclable wastes for the project. • Evaluate waste producing practices and propose alternatives • Compare the costs of reusing materials to purchasing new. • Require a Waste Management Plan for service contractors. See Waste Management Plan and Reporting Form. • Communicate your waste management plan and targets for the project.

  47. IMPROVE PROPOSED GUIDELINES 2. Bidding Phase • A Waste Management Plan should be included in the list of technical requirements. • A Bidder should identify potential waste materials generated from construction and appropriate disposal methods.

  48. IMPROVE PROPOSED GUIDELINES Form No. _____ ADB Waste Management Plan

  49. IMPROVE

  50. IMPROVE PROPOSED GUIDELINES 3. Implementation and Monitoring Phase • 3.1 Construction practices that can prevent waste • Orient the Service Contractor on the Waste Management Plan and monitor its implementation/ • Construction activities should be segregated onsite for ease of material segregation e.g. cutting areas should be separated from assembly areas, excess wood materials can thus be easily collected. • Reuse wood concrete forms or reusable metal forms. • Designate areas for waste prevention, such as the material storage, central cutting, and recycling stations. • Designate a storage area for materials and implement effective handling procedures to prevent loss or damage.
