Engineering services

We support our customers both in the design and planning of energy infrastructure systems, as well as in the construction of new (or optimization of existing) process and energy facilities.

Following are our individual services in engineering:

Planning of process and energy facilities:

Infrastructure planning:

Detailengineering in 2D/3D 


ICB conducts detailed planning in 2D or 3D and creates the desired documents for the individual project phases:


  • Procurement
  • Assembly
  • Commissioning


The individual documents are either derived from 3D modeling or created directly as 2D elements:


  • Production, assembly and installation drawings
  • Pipe and steel building plans
  • Bill of materials (BOM)
  • P&I diagrams
  • Isometry


Documents are drawn up in close coordination with our customers and/or with the contracting company.

Pipe Planning


Pipe planning represents a particularly sensitive aspect of 3D planning. Various legal, normative, technical, and customer-specific requirements need to be harmonized. For this reason, pipe planning significantly influences the design, construction, as well as the stable, efficient, and economically successful operation of a facility. Services in the field of pipe planning include:


  • Design review
  • Layout planning
  • 3D routing, including collision and escape route analysis
  • Material take-offs
  • Creation of hook-ups
  • Service life calculations
  • Calculation and design of custom components
  • Pipe support planning
  • Secondary steel structure planning

Pipe classes and standards


By defining pipe classes and company technical guidelines—so-called plant standards—planning, setup, operation and maintenance of a plant can be made considerably more efficient.

The main factors to be defined are:


  • Applicable regulations
  • Application
  • Operating medium and operating parameters
  • Operational and occupational safety
  • Service life


Based on your individual specifications and taking into account current legal requirements and standards, ICB creates pipe classes and/or plant standards specifically tailored to your business so that you reach your target more quickly, smoothly and efficiently.

Pipe stress calculation – pipe statics


Pipe stress analysis guarantees that piping is not stressed beyond permissible limits by loads from operation and external influences. It also provides the required design parameters for pipe suspensions and the forces and deformations caused by interfaces and pipe sockets.


We conduct the required pipe stress analysis and provide you with suitable alternatives if a given piping layout does not work, i.e. would lead to overloading. Pipe stress analysis is conducted in accordance with standards. The most well-known are:


  • EN13480
  • ASME B31.1 and B31.3


The use of standard calculation software guarantees that all the relevant factors involved are taken into account logically and in compliance with regulations.


  • Internal pressure
  • Static and dynamic loads
  • Load cases
  • Type of installation


We prepare the following documentation in response to the order and according to the customer’s requirements:


  •  Classification according to EC directive 2014/68/EU (Pressure Equipment Directive)
  •  Documentation for the preliminary inspection
  •  Bearing concept and bearing loads

As-built recording and engineering in existing facilities


The life cycle of industrial plants is generally designed to last several decades. As-built plans of plants and factory buildings are often out of date, no longer match the current conditions or are simply no longer available.


The recording of pipe routing on site by our experienced employees as well as measurement with 3D laser scanning ensures a rapid and precise survey that is indispensable for upcoming adaptations. Furthermore, all other existing documents are reviewed and evaluated to obtain additional information for the as-built assessment.


In addition, this procedure offers great advantages in efficiency and planning security for documenting parts of plants that are difficult to access.


The most common applications are:


  • Edge detection
  • Collision analysis
  • As-built documentation
  • Planning of structural changes
  • Replanning of technical modifications


The advantages of these methods for plant manufacturers and operators are obvious:


  • Short plant downtime
  • Implementation during operation
  • Digital processing
  • Reliable foundation for documentation and planning

Steelwork construction and statics


ICB takes over the static design of steel structures and constructions (e.g., stages, catwalks, platforms, bridges, bearing supports) according to current regulations, for example Eurocode.


The task is to verify adequate structural safety under defined load scenarios (e.g., static and dynamic mechanical loads, environmental stress, earthquakes, combined stresses) and the optimal design from an economic perspective (e.g., weight, setup costs, operating costs, service life, possible upgrades).


The scope of static design (e.g., profiles, structural system, node type) is agreed upon with the customer in relation to the project. Verification is provided by a calculation report that may be reviewed if desired, i.e. prepared for review and approval by a third party.

In addition, we implement the design of steel structures for you according to EN 1090-2:


  • Material and parts lists
  • Individual component drawings including NC or DXF files
  • Assembly drawings
  • Installation drawings


We use standard software systems for implementation.

The result is a complete steel construction design as the basis for tenders, orders, manufacturing and setup.

Pressure vessels and accessories


ICB completes the design and calculation of pressure vessels and parts of pressure-retaining equipment according to the following recognized European and foreign standards and regulations:


  • EN12952, EN12953
  • EN13445
  • EN12516
  • AD2000
  • ASME B16.34
  • Other


Examples of pressure vessels are:


  • Process containers, equipment, tanks
  • Separators, collectors, filters
  • Containers under external excess pressure
  • Gas storage containers (fluid gas tanks, cryotanks for liquified gases)
  • Heat exchangers (condensers, heat exchanger)
  • Pressure reservoirs


Pipes are not strictly regarded as pressure vessels and thus are designed and calculated according to separate standards/regulations. Valve bodies can be calculated—depending on how they are constructed—according to current regulations for pressure vessels or pipes or according to other specific standards.


Since 2002 pressure vessels with a maximum permissible operating excess operating pressure of over 0.5 bar have also been subject to EC directive 2014/68/EU (Pressure Equipment Directive).



Plant documentation is commonly referred to as “as-built” documentation. In the course of assembly or installation, the following documents must be provided to the operators:


  • Plant description
  • Functional description of the entire plant and its constituent parts
  • Operating and maintenance instructions
  • Technical drawings and plans
  • CE marking, manufacturer’s recommendation, certificate of conformity
  • Inspection results and inspection reports


There are different reasons for why customers are missing documents or these documents are no longer valid:


  • Changed government regulations
  • Changed government requirements and/or standard requirements
  • Old plants with undocumented modifications
  • No prior as-built documentation
  • Loss due to force majeure
