- 1. Chamath Wijeratne Work History Dec 2011 – Present Project Manager, Projects – High Density, Ausgrid • Responsible for delivering network assets (>$10M) through project planning, risk analysis, proposal, civil and electrical design, civil and electrical construction, testing, commissioning and closeout stages. • Managed the following projects: o Rebuilding Canterbury 132kV/33kV 194MVA sub-transmission substation ($45M brownfield) to replace equipment, which was reaching end of serviceable life and mitigate safety issues. § Relocating capacitor banks, ripple filters, underground services § Constructing new control and switch room § Replacing 132kV and 33kV outdoor yards with indoor gas insulated switchgear § 132kV (x4), 33kV (x19), 11kV and 415V feeder/circuit augmentations o Installation of 132kV Ring Main Circuit Breakers at Marrickville 132kV/11kV 72MVA zone substation ($18.6M brownfield) to minimize the risk of outages due to transformer faults (improved operation and reliability) of the associated transmission feeders. § Developed project proposal and execution plan § Demolishing existing amenities § Constructing new control and switch room § Installing 132kV GIS units § 132kV feeder (x4) connections § Green-field brownfield secondary systems integration o Installation of 132kV Ring Main Circuit Breakers at St.Peters 132kV/11kV 87MVA zone substation ($22.5M brownfield) to minimize the risk of outages due to transformer faults (improved operation and reliability) of the associated transmission feeders. § Provided project management, construction and commissioning advice for the. § Developed project proposal and execution plan § Demolishing existing structures, buildings § Relocating underground and overhead services § Constructing new control and switch rooms § Installing 132kV gas insulated switchgear § Installing 11kV/415V auxiliary substations § Augmenting 11kV and 415V services o Replacing switchgear at Dulwich Hill 11kV 62MVA zone substation, which is approaching end of serviceable life ($25.5M brownfield). § Underground service relocation § Construction of new switchroom § Equipment installation § Feeder transfers o Replacing Hurstville North 132kV/11kV 66.7MVA zone substation ($31.1M greenfield) to supply forecast demand increases in the area. § Defect rectification of electrical installation
- 2. § Commissioning all primary and secondary equipment § 132kV feeder augmentations § Decommissioning old substation o Kogarah 91H VT height platform to eliminate height safety risks to operating staff. o Canterbury No.3 Tx gantry replacement and refurbishment to eliminate risks from gantry failure to personnel, equipment and network load. Communication • Developed and implemented communications plans for each project phase. • Communicated to all relevant stakeholders complex work sequences required to commission brownfield assets via presentations, one-on-one information sessions, phone conversations, staging diagrams, commissioning plans and network access plans. • Ensured each workgroup understood expectations - questioned and regularly sought feedback from key workgroup members. • Communicated changes to complex commissioning programs via weekly meetings, commissioning plans, network access plans, staging diagrams, network switching/earthing/lock-out instructions, group discussions and one- on-one dialogs. Human Resources • Managed the changing requirements of key stakeholders, internal service providers, internal subject matter experts, internal clients, external consultants, external regulatory authorities (e.g. city councils etc.) and community members. • Managed competing demands from key stakeholders. • Resolved conflicts between staff, contractors, alliance partners and other stakeholders. • Managed up to four direct reports - project engineers, graduate engineers and project construction superintendents. • Identified and facilitated areas of development/improvement for engineers. • Completed six-monthly or annual performance reviews for graduate engineers. • Monitored the performance of Project Construction Superintendents. • Identified knowledge gaps for Project Construction Superintendents. • Provided training and mentoring to reduce knowledge and skill gaps. Procurement • Managed the procurement of equipment and services throughout the life cycle of the project. • Managed the evaluation and approval of variations and extensions of time. • Reviewed procurement plans and tender documents. • Evaluated tenders for civil construction work packages. Risk • Identified, controlled, monitored and managed project risks throughout the project life cycle. • Monthly review and update of risk registers. • Facilitated and lead risk and opportunity workshops.
- 3. Change Management • Managed changes to scope, schedule, network requirements and quality standards throughout the life of the project. • Practiced agile change management and minimized impacts from latent conditions, organizational restructures, changes in network standards and changes to client needs. Cost Management • Reviewed detailed project estimates and controlled project costs throughout the project life cycle. • Used Visual Basic for Applications, to automate the process of mapping cost center expenditures (exported via SAP and Microsoft Access) to project cost breakdown structures (Microsoft Excel) and performed earned value analysis and forecast costs to complete. • Facilitated value management workshops that delivered over $1M in cost reductions for the Marrickville and St.Peters 132kV ring main circuit breaker projects. Quality • Ensured key-deliverables at each project phase was completed to the required quality. • Ensured the Inspection, Test and Quality Plans were completed at the time of energisation. Safety and Environment • Identified, controlled, monitored and managed Work Health and Safety risks over the construction and commissioning phases. • Developed situation-specific Safe Work Method Statements. • Developed integrated Safety Management System to manage Work Health and Safety of local and remote work sites and implemented this system via Site Specific and Project Specific Safety Management Plans. • Updated Safety Management Systems to comply with legislation as new codes of practice etc. were released. • Completed at least two work site inspections and safety interactions each month for all active project sites. Integration • Developed project proposals for the Marrickville, St.Peters, Dulwich Hill and Kogarah height platform projects. • Provided monthly updates of key project performance indicators (schedule, percentage complete, actuals vs. forecast cost to complete, safety and environmental incidents etc.) to the board of directors. • Facilitated Value Management workshops to deliver value outcomes for clients and stakeholders. Engineering and Technical skills • Maintained detailed project schedules using the Primavera P6.
- 4. • Using Visual Basic for Applications, automated the process of mapping cost center expenditures (exported via SAP and Microsoft Access) to project cost breakdown structures (Microsoft Excel) and performed earned value analysis and forecast costs to complete. • Developed complex commissioning plans to construct, test and commission brownfield network equipment. • Wrote network element isolation, earthing and lockout instructions for the Sydney Control room to facilitate the construction, testing and commissioning activities. • Assessed and balanced project needs (delays, cost increases etc.) with risk exposure to personnel, equipment and customers (minimizing risk to network loads). • Trained project engineers to write network isolation work instructions. • Managed the logistics and sequence of modifying/commissioning network assets such as feeders, transformers, switchboards, ring-main-isolators, circuit breakers, reactors, overhead transmission spans etc. • Developed multi-variable optimization algorithms to sequence brownfield 132kV and 33kV feeder transfers.
