2 Outline Who is Golder? Sustainable Development (SD) and Value Engineering (VE) Concepts Project Overview with GoldSET GoldSET Benefits How it Works Case Study (online) Conclusion

3 Who is Golder? Employee owned since our foundation in 1960 Most respected global group specializing in ground engineering and environmental services Highly-skilled engineers, scientists, project managers and other technical specialists committed to our clients success 6,000 clients across multiple industries 12,000 projects each year, both large and small 7000 employees in more than 160 offices

4 Definitions Definition of Value Analysis for Engineering Projects (VE) A systematic and function-based approach to improving the value of products, projects or processes. Definition of Sustainable Development Development that meets the needs of the present without compromising the ability of future generations to meet their own needs. Similarities Many definitions Abstract notions Involves choices Our Common Future, WCED (Bruntland Commission), 1987 November 19,

5 Sustainable Development The Evolution of Decisions Development that meets the needs of the present without compromising the ability of future generations to meet their own needs. (Our Common Future, WCED, 1987) PEOPLE Social PROFIT Economics Decisions PLANET Environment

6 Sustainable Development Successful Sustainable Businesses Development that meets the needs of the present without compromising the ability of future generations to meet their own needs. (Our Common Future, WCED, 1987) It s about maintaining the delicate balance between Profit, People and Planet: the new corporate Triple Bottom Line PROFIT Economics PEOPLE Social PLANET Environment

7 Sustainable Organizations : What are the Drivers? Development of sustainable projects and organizations requires the management and cohesion of conflicting priorities: Profit: Corporate and shareholder value, stakeholders, industry, bankers People: Employees, Consumers, Communities, Countries (governments) Planet: Meeting global and local agreed-upon environmental standards Rising Stakeholder Expectations Growing Complexity of Sustainability Issues ORGANIZATION Multiplication of Principles, Indicators, Guidelines, etc. How to manage the pressure?

8 Sustainability: Two Levels of Application 1. To integrate sustainability principles in organizational management: Benchmarking Sustainability corporate plan Carbon-neutral strategies Community involvement Eco-efficiency 2. To integrate sustainability at the project level: Decision support tools Life-cycle analysis GHG inventory Eco-efficiency Evaluation of social impacts

9 GoldSET : a Tool to Help Integrate SD at the Project Level GoldSET A Sustainability Support Decision Tool developed to help project managers and engineers: 1. Embed the Triple Bottom Line principles at the project level (bottom-up approach) 2. Manage conflicting pressures from various stakeholders 3. Make transparent and impartial decisions 4. Reduce the overall economic impacts through optimization

12 GoldSET: Step 1 Project Description Objective(s) Definition Site Specific Conceptualization of Site Conditions Stakeholders mapping

13 GoldSET: Step 2 Generating Ideas Options Description Fatal Flaw Analysis: Objectives Cost Duration Technical Legal

14 Indicators Strategic Issues: Environmental Social Economics Rigorous Selection process: e.g. GEMI Metrics Navigator Linking to Stakeholders through: International Standards & Best Practices Corporate Objectives Legal Requirements GoldSET: Step 3 Criteria Selection and Definition

15 GoldSET: Step 4 Ideas Ranking Scoring Quantification of Indicators: Specific to Client Requirements Evaluation of Options based on Triple Bottom Line : Eco-efficiency Cost Benefit Analysis Stakeholder Concerns Structured System for Ranking Options: Tailored Scoring & Weighting Ternary Diagrams OPTION A OPTION B OPTION C OPTION D Recommendations to support decision making: Tangible Transparent Optimized Automated Reporting

16 GoldSET: Step 4 - Weighting Scoring Scoring Quantification of Quantification Indicators: of Indicators: Specific to Client Specific Requirements to Client Requirements Evaluation of Options Evaluation based of on Options Triple based Bottom on Triple Line : Bottom Line : Eco-efficiency Eco-efficiency Cost Benefit Analysis Cost Benefit Stakeholder Analysis Stakeholder Concerns Concerns Structured System Structured for Ranking System Options: for Ranking Tailored Options: Scoring & Tailored Weighting Scoring & Weighting Ternary Diagrams Ternary Diagrams Interprétation des résultats

19 GoldSET: Step 5- Present Ideas Interpretation & Reporting OPTION A OPTION B OPTION C OPTION D Recommendations to support decision making: Tangible Transparent Optimized Automated Reporting OPTION A OPTION B OPTION C OPTION D Recommendations to support decision making: Tangible Transparent Optimized The best approach from a sustainability standpoint is based on: The biggest, most balanced triangle. Highest performance in each dimension Balanced performance between all dimensions Automated Reporting Local specificities must be considered in selecting the option

20 Case Study : Contaminated Yard Project Description Presence of a diesel plume covering approximately 20,000 m 2 Apparent thickness ranges from 5 cm to 2 m Potential for off-site impacts Free phase product located in fractured bedrock Objectives & Concerns 1. Minimize expansion and migration of LPH and dissolved phase plumes 2. Prevent off-site migration 3. Avoid potential litigation Contaminate d Area Yard

21 Case Study : A First Paradigm Shift! The path that led to new investigations: Unsatisfactory results from the Extraction program (cost vs. results) Client s desire to go forward with sustainability activities The performance of five different remedial technologies were explored with GoldSET: 1. Interceptor Sumps 2. Interceptor Trench 3. MPE (Multi-Phase Extraction) 4. Well-Based Hydraulic Barrier 5. In-Situ Treatment by Oxygenation Barrier

22 Case Study : The classic approach (objective based)! Step 4: Option Evaluation (Indicator Scoring) INDICATOR Interceptor Sumps Interceptor Trench MPE (Multi-Phase Extraction) Well-Based Hydraulic Barrier In-Situ Treatment by Oxygenation Barrier Free Product Off-Site Migration Public Safety Worker's Safety Standards, Laws and Regulations Net Present Value of Options' Costs Potential Litigation Environmental Reserve Service Reliability and Performance TOTAL:

Step 4: Option Evaluation (Indicator Scoring) CODE INDICATOR Interceptor Sumps Interceptor Trench MPE (Multi-Phase Extraction) Well-Based Hydraulic Barrier In-Situ Treatment by Oxygenation Barrier ENV-1 Soil Vapour Intrusion ENV-2 Groundwater Quality ENV-3 Free Product ENV-4 Water Usage ENV-5 Off-Site Migration ENV-6 Greenhouse Gas Emissions ENV-7 Energy Consumption ENV-8 Wastes ENV-9 Soil Quality SOC-1 Public Safety SOC-2 Worker's Safety SOC-3 Duration of Work SOC-4 Quality of Life (During the Project) SOC-5 Local Job Creation and Diversity SOC-6 Response to Social Sensitivity SOC-7 Standards, Laws and Regulations SOC-8 Management Practices ECONO-1 Net Present Value of Options' Costs ECONO-2 Potential Litigation ECONO-3 Financial Recoveries ECONO-4 Environmental Reserve ECONO-5 Service Reliability and Performance ECONO-6 Reliability (Maintenance and Repair) ECONO-7 Technological Uncertainty ECONO-8 Logistics WEIGHT

24 Case Study : A First Paradigm Shift! The performance of the technologies in each aspect results from the integration of the scores for each indicator Three options seem to perform better based on the results from the first iteration

25 GoldSET: A First Paradigm Shift! Second Iteration GoldSET allows the refinement of the evaluation by deselecting options When comparing only the three best options from the first iteration, it became obvious that the Hydraulic Barrier was underperforming when compared to the other two options The option was ignored and testing took place with the other two

26 Case Study : A First Paradigm Shift! A detailed analysis of the indicators showed that the differentiation came from an underperformance in seven different aspects It s the integration of the performance for each of the indicator that sums up the overall performance of each option CODE INDICATOR MPE (Multi-Phase Extraction) Well-Based Hydraulic Barrier In-Situ Treatment by Oxygenation Barrier ENV-1 Soil Vapour Intrusion ENV-2 Groundwater Quality ENV-3 Free Product ENV-9 Wastes ENV-10 Soil Quality SOC-6 Response to Social Sensitivity ECONO-5 Reliability (Maintenance and Repair) WEIGHT

27 Pilot Test Findings and a Second Paradigm Shift Data analysis from MPE testing showed erratic behaviour of the LNAPL thicknesses (well screen submerged and increase in LNAPL thick.) This observation challenged the way we interpreted diesel transport with a water table fluctuating between the overburden and the fractured bedrock Pilot Testing for the oxygenation of groundwater showed that biodegradation activities were occurring underneath the site Based on the new conceptual model, the monitoring for natural attenuation was considered in the subsequent evaluation of options

28 Pilot Test Findings and a Second Paradigm Shift The natural attenuation option was evaluated and considered to be the preferred remedial option, pending collection additional data November 19,

29 A Tiered Approach with GoldSET Data Requirements Uncertainty Tier 1 Preliminary evaluation Qualitative criteria Indirect stakeholder involvement Tier 2 Semi-quantitative evaluation First order of magnitude estimations Stakeholder consultations Tier 3 Detailed evaluation Quantification of key criteria based on modeling, life-cycle/cost-benefit analyses Extensive stakeholder consultations Sensitivity analyses
