We are industry leaders in providing a range of tools, techniques and software to enhance our client’s estimating accuracy and visualisation of potential efficiencies . With more accurate estimating capabilities our clients can make more intelligent and information-driven business decisions, reduce cost uncertainty across the project lifecycle and ultimately lower solution delivery costs.  \nIncreas ing c l ient data maturity  \nCost Modelling  \n(Process)  \nHigh Level Benchmarking  \nParametric Models  \nCost Modelling  \n(Equipment)  \nMachine Learning  \nTraditional CAPEX BU Estimating  \nParametric Models  \nUnit Cost Benchmarking  \nConcept design and optioneering Design development and ATC Tender evaluation  \nVisualisation and estimating software  \nWe offer estimating solutions for infrastructure clients across multiple sectors, including: water, rail, highways, aviation and nuclear. Our approach is to tailor the estimating solution to the project life cycle stage, available design scope and the bespoke client needs rather than universally apply traditional bottom up estimating or a standard top down solution.  \nDue to the scale and-for most infrastructure sectors—the need to operate under a regulatory framework, the existing collation of structured historic and estimate cost data presents a unique opportunity for clients to transform this cost data and leverage it into more accurate estimating tools for future projects. Our classleading experience in this field and the combination of our estimating and cost intelligence teams mean weare well-placed to assist our clients with a range of innovative solutions.  \nConcept design and optioneering  \nHigh level cost modelling (CAPEX and OPEX)  \nEarly stage cost modelling provides an auditable method of rapidly establishing budgetary figures in the absense of project scope, and when based on a client’s own historical data is a robust approach to developing future business plans.  \nAssemblies  \nInfrastructure clients may not always hold or have access to a historic dataset of project costs from which to create models for estimating purposes. Assemblies accept the bare minimum of asset details to provide an auditable cost estimate based on a rates library, allowing for the creation of repeatable and consistent costing across programmes.  \nBenchmarking  \nBenchmarking is an essential service for infrastructure clients to establish early stage funding requirements and to ensure contractor returns and estimates align with market expectations. AECOM as one of the largest multi-disciplinary consultancies in the world is uniquely placed to assist clients with benchmarking, especially international and pan-sector analyses.  \nHigh level cost modelling (CAPEX and OPEX)  \nKey services  \nEarly-stage whole life estimating using top-down industry models under flexible processes to accomodate varying client requirements, applications or data.  \nCost data capture: Understanding the value of consistent data capture against a well-defined breakdown structure can support both the creation of a breakdown structure to facilitate the future estimating and/or the mining of data against an established structure.  \nSelected experience  \nTo assist Affinity Water in the creation of auditable cost models for their PR19 Business Plan, AECOM created a range ofcapex and opex cost models from historic company data and third party sources to enable accurate top down estimates to be created for a range of project solutions.  \nRegulatory business plan support, Anglian Water  \nAECOM are providing a range of PR19 analytics and cost intelligence  \ncommissions which have included client data auditing and production of hundreds of capital cost models.  \nAssemblies  \nKey services  \nAECOM are the market leaders in the creation of bespoke assembly templates for infrastructure clients.
