Overview
From isometrics, bills of materials, bills of quantities or other quantity bases, ADLER derives traceable quantity, effort and cost assumptions. The work can be item-based, factor-based or weight-based, or follow a specified estimating scheme. Method, price basis, boundary conditions and output format are agreed before work begins.
Technical estimating from a traceable basis
A reliable estimate starts with clear quantities, methods and boundary conditions. ADLER evaluates technical documents and prepares the assumptions in the agreed structure. This applies to bids as well as to variations and comparison calculations.
Estimating can be commissioned as an individual task, on a project basis or on an ongoing basis for recurring tenders.
Required basis
Depending on the method, the work requires isometrics, bills of materials, materials, dimensions, welding and testing details, bills of quantities, factors, price bases or the client’s own templates. Missing or contradictory information is flagged as points for clarification.

Frequently asked questions
Can ADLER work to our estimating scheme?
Yes, provided the rules, parameters, templates and any required system access are made available.
Is an estimate possible without complete isometrics?
That depends on the method and the purpose of the estimate. Missing bases are named as points for clarification before or during the work.
