What we do; Planning
Matrixed organization
Same specilized workers involved indifferent projects teams leaded bydifferent project managers
Predefined Standard ScopeDetailed jobs, with estimation of times,
costs and spares. Used as a baseline forthe definition of the final scope.
Involvement of technicians asapThrough work teams complying withmatrixed organization where detailed
scope and planning is propposed.
Consolidation by managersProjects are merged into a consolidatedplanning by team managers with onlyone overhaul coordinator.

What we do; Measuring
Economical MeasurementsControlling by projects. Each project corresponding to a main system:1. Boiler2. Generator & Turbine3. Secondary Air Preheaters4. ESP and Ducts
5. Cooling Water System6. Mills and Combustion7. Fly-ash and Bottom-ash Handling System8. Main Fans (IDF & FDF)9. Condensate and Feedwater System10. Main transformers and power distribution
11. HV Motors12. Control System13. FGD14. Others
This allows to compare developing of OPEX between overhauls.Spares and materials, tools and equipment, fungibles and labour are
considered separatelly.
