Aerni consulting was founded in 2001, its focus is
consulting in the system- and plant business
Our Goal is helping companies to become more
competitive
Support of companies and teams with proven
methods, innovations and ideas. But also with a pragmatic approach and a cross functional view of the company
Or with project-/program management of defined
improvement projects/programs
1
Aerni consulting has developed proprietary methods and tools in the
following areas:
• Plant optimization/development and cost reduction
• Knowledge management and reuse in the engineering process,
including more accurate cost estimating
• Prototype for cost estimation in Comos (piping mat, pref and erection)
• Process reengineering adapted to the plant business (6 Sigma)
• IT application benchmarks on Net Present Value basis
• Innovation (business, products and processes)

The thorough implementation of optimized/modularized/standardized plants/reused engineered solutions will allow to achieve significant more value for all stakeholders
Customer Plants, services, technologies Workflows Capabilities
Tools and methods (PLM, CAEs, 6 Sigma, DFx, etc)
Performance, cost consistency,quality and cost
Customer needs Best-in-class people Optimization/ modularization/ standardization 6 Sigma Experience– Life Cycle Cost (LCC) reduction in the plant building industry
Improvement of 10-20% in Net Present
Value for system/plant
Reduction of engineering hours and cycle time up to
50% and cost of poor quality by 25%
Only smart cost estimating and control models allow to support the LCC / cost reduction potential in the plant business industry
Major elements of a LCC optimization/ cost reduction program
1: Get cost transparency
– Plant / equipment / bulk cost structure – Baseline setting
2: Set targets and Priority setting
3: Optimize process and reduce costs (LCC reduction)
– Process optimization
– Key package units/equipment / commodity strategy – Low cost country sourcing (LCS)
– Redesign to cost and standardization
4: Measure and follow-up: Initiative monitoring and metrics 5: Apply to projects: compliance mechanisms
Our experience – R&D and cost reduction
Our experience is in the implementation of cost reduction and/or performance improvement of new products
Modularisation/Standardisation of wet cooling towers
The team (England, France, Germany, Belgium) developped a new family of wet cooling towers within 4 months with a cost reduction of
17%
Modularisation/Standardisation of waste heat recovery boilers for combined cycle power plants.
The team achieved a cost reduction of 25% within 8 months
Support in the development of a new pump family (conjoint Analysis, FMEA and modularisation)
Voice of the customer for combined cycle power plants
Development of a cost reduction methodology for the plant business and
development of new cost estimating workflow for piping and civil including new structures, unit rates and calculation of norm hours for erection services
Project management for the modularisation/standardisation of steam reformers Improvement of plant NPV by approx.15 % in 4 months
The various structures coexist for the necessity of order execution, the
relationship are not made explicit in a common data model and consistency is difficult

Piping BOM Current situation
Various tools and structures characterize often the cost estimating and cost control landscape
• One tool to consolidate the cost from various disciplines and to calculate final price to customer (own development, SAP, MS-excel or other).
• Each discipline quantifies their Material Take-Offs (MTOs) or Bill Of Quantities
(BOQs) with their unit rates (own developments, MS-excel) and enters the summary data into the above consolidation tool.
• Division of work is ensured by project management and discipline in a separate document or ev. in the cost consolidation tool.
• Data integrity between disciplines is more or less realized through equipment lists, PFDs and layout drawings
• Each main location often has its own tool/data
• Cost objects are not attached to engineering objects with the consequence that engineers would like to know the cost to optimize their plants but have seldom the information at their fingertips
• Purchase order positions in the ERPs often have a different granularity than the unit rates negotiated with the supplier
Economies of scope and scale, cost transparency and reduction of
complexity are also in the plant business important cost reduction drivers
• Plant optimization/cost reduction is not feasible without cost information
• Accuracy of cost estimation is better if a company can rely on data from past projects (BOQs and unit rates)
• Data consistency between disciplines and project phases (tendering, basic
engineering, detailed eng, etc) can best be achieved by using the least amount of databases and structures/data models which ensure consistency between discipline and project phases
• Avoid if possible data duplication and ensure that data are only entered once
• Start IT projects with the big picture in mind but with a limited scope and complexity to achieve quick results
Cost tools required by an EPC company
• The process and 3D configuration of the plant shall automatically produce the necessary
cost objects to ensure consistency of scope and cost (Reuse information from ongoing or closed projects in tendering and execution)
• Tool to achieve target cost in proposal and order execution
• Confidence in estimate (Goal +/- X% between as sold und as built)
• Allow management to compare BOQs and unit rates between the different projects for
estimates and as built projects
• Control BOQs and unit rates from tendering to as built (status as ordered, as engineered, as
procured and as built)
• Support for the optimization of technical solution( Allocation of cost to the structures of the
technical solutions (Process catalog and 3D catalog)) by allowing engineers to see the cost of what they have engineered
• Show quickly and quantify precisely the effects of changes to the supply- and work-split
• Flexibility with regard to price changes (project in a different country or with other suppliers
• Allowing Bids from key suppliers with slender resources and BOQs of most expensive items
• Allocation of cost to disciplines
• Seamless transition from old cost structure to new structure
