ROSA – Distinguished by versatility

From pre-engineering to the start-up.

There are a great variety of definitions for the term “project”, for example according to DIN, IPMA, PRINCE2. All definitions have something in common: a project is a targeted, one-time undertaking that consists of a starting and finishing date and is carried out in order to achieve an objective (e.g. a product or service) taking into consideration requirements in connection with time, resources and quality.

Hence, according to DIN 69901, project management is defined at the complete set of management tasks, organization, techniques and tools for the initiation, definition, planning, control and conclusion of projects.” A project manager is responsible to the customer for the project and has a duty to report. To carry this out, he requires knowledge of project management, product-specific or domain knowledge, endurance and resilience, interpersonal and communication skills as well as “common sense.”

Plant engineering and construction differentiates between the different phases in a project.

Pre engineering
The technical, financial and administrative boundary conditions are determined and compared to the requirements of the customer. Different concepts are compared in a feasibility study, and there is a decision as to whether or not the plant will be built.

Basic engineering
The decision for the technically and economically most advantageous concept is made by basic engineering, and it starts the development phase with the first determination of the costs and revenues for the pipelines needed for a power plant. At the end of this phase is the procedural basis and planning, 3D model and conceptual design, specialized design planning (e.g. pipeline construction, electrical systems, instrumentation and control technology, construction, technical building equipment and much more), the concept for the health and environmental protection, safety protection, a concept for procurement and the structure for the next steps of project management. All the necessary decisions for the construction of the plant are made here.

Detail engineering
The exact description and detailed design of the individual technical components happens here. In the process, all the documents are prepared for the various trades that allow the construction of the plant. The individual trades are process engineering, construction (building construction and civil engineering and the structural steelwork), systems engineering (piping, apparatus construction and mechanical engineering), electrical engineering (high and medium voltage), technical building equipment as well as procurement.

This phase of the project addresses the specific request for the specific components for the individual trades described in detail engineering. Different offers are collected for this and checked for cost, quality and on-time delivery performance and then selected. The respective components are then ordered.

Construction phase
The plan that was developed is executed at the construction site with the ordered components in this construction phase. Green-field (in the open countryside) or brown field (e.g. in a chemical park) are differentiated here. The individual trades of the plant are gradually built, starting with the building construction and civil engineering, foundation construction and structural steelwork.

The commissioning of the new plant takes place at the end of a project management cycle. The first use of a plant for which clean documentation can be demonstrated (e.g. EC directives, EU declaration of conformity, CE marking) is called a cold start-up. Water is mostly used as a medium in order to give the machine an initial trial run. This is followed by the hot start-up with the actual medium, and the plant begins its service.

This may be for building a new plant or re-engineering or retrofitting an existing one.

Project management in plant engineering and construction comprises:

  • project coordination and assistance
  • scheduling and tracking
  • project development
  • site management
  • claim management
  • document management

On the path to Industry 4.0.

As a concept, systems engineering describes the machinery, equipment and apparatus that are systematically combined in a spatial interconnection. Here, individual components are linked into a system in a functional, control and safety respect.

The systems engineering market has been on a growth path for years due to the topic of Industry 4.0 and networking of the development, production, installation and maintenance of technical components or alternatively systems. ROSA has outstanding expertise in this environment and has filled many projects with experienced specialists. If you are looking for a systems engineering expert or are interested in project orders or a permanent position as such an expert, then you’ve come to the right place. Seeking? Finding! Reliably and quickly.

From electrical components up to Industry 4.0.

Malfunctions of any kind are an expensive proposition for plants in all areas. For this reason, E-I&C technology usually represents the heart of all plants, and is enjoying special attention.

Electrical engineering is a separate area of ROSA that comprises engineers for research and development as well as production technology of electrical equipment. Due to the increasing proliferation and implementation of plant engineering and construction with electrical components over the Internet of Things with production data put in the cloud, up to the Industry 4.0 model, ROSA can fall back on already existing know-how and its pool of experts in the area of electrical engineering for its customers in plant engineering and construction.

Cost and technology – under control right from the draft.

Construction technology is a common generic term in construction for the technical-design aspects of civil engineering. Many areas of teaching, training and research at universities address this term.

One of the crucial tasks of the area of construction engineering, particularly in the area of projects in plant engineering and construction, includes taking technically economical aspects into consideration at an early stage in the design. It is decisive for minimizing the subsequent construction costs. Experienced engineers and technicians accompany these projects from the planning phase to the implementation phase. We provide experienced specialists from the construction industry both for basic/detail engineering as well as for engineering for public authorities and subsequent construction and commissioning.

ROSA has longstanding expertise in the area of construction engineering and has filled many projects with experienced specialists. If you are looking for a systems engineering expert or are interested in project orders or a permanent position yourself as such an expert, then you’ve come to the right place.

Compliance with the legal approvals framework.

In addition to the technical requirements and the financial and organizational conditions, environmental approval procedures and safety considerations play a central role in the construction of a process plant.

The increasingly complex environmental and administrative principles must be observed in the highest degree in order to meet the legal and official requirements. The legal approval framework and requirements as well as the site-specific conditions of use must be determined and included as early as possible.

The foundation for the approval process includes the following laws, among others:

  • Federal Emission Protection Act (BImSchG)
  • Water Resources Act (WHG)
  • Equipment and Product Safety Act (GPSG)
  • Recycling and Waste Management Act (KrW- /AbfG))
  • Construction law (BauGB)

In the area of engineering for public authorities and safety engineering, the ROSA service portfolio covers the following areas:

  • safety management
  • emissions plan
  • reporting and consulting
  • process audit

ROSA has decades of experience in the use of freelance experts or its own employees in the area of safety and public authorities engineering.

In the transformation from paper to bits.

Database-driven management of electronic documents is what is meant by the concept of document management. Today, we find ourselves in a stage of transformation from purely paper-based documentation to fully-electronic documentation. Hence, documents that were originally paper-based are currently being entered electronically into a digital database. This huge amount of data forms the basis for the new digital and modern plant engineering and construction.

The documentation can have different forms:

  • “As-built” documentation
  • CE-compliant documentation
  •  revision of existing plans
  •  editing of supplier documentation

ROSA has extensive experience and good placement results in the area of documentation, whether for freelance professionals or employees. Hence, ROSA has established itself as the point of contact both for specialists looking for new projects and challenges and for customer companies, and brings the right experts and projects together. Are you looking for a new challenge or a capable document controller? We will find the right project for both sides. Reliably and quickly.
