The concept of modular solutions is currently one of the most popular trends in construction. Due to market expectations and the limitations of manufacturers and contractors, the slogan of modular solutions together with the slogan 'prefabrication' are currently declined in all possible cases and numbers.

The use of BIM technology in projects by Walraven
BIM technology and dedicated tools are currently found in most implementations. Every major project is currently implemented in the BIM environment – for this reason, visualization of solutions is one of the most common expectations. Based on visualization and initial solution models, it is possible to meet another expectation, such as developing an accurate cost estimate that will allow control over the investment process. The cost estimate should be completed in the shortest possible time while maintaining high accuracy.
The modular approach, apart from the design and cost estimation stage, is supported by the expectation of reduced implementation time, which has a measurable impact on the final value of the investment. The design and specification stage in the case of modular solutions is seamlessly connected with subsequent stages and production processes and with the final assembly of solutions.
Walraven has repeatedly delivered solutions developed using the RapidStrut® and Maxx fastening systems for the construction of support frames for equipment in recent years. Very often, the delivery of the device fastening structure was the beginning of further work related to ensuring safe access to machines and equipment for service purposes. Technical guidelines for the access to machines and equipment are presented in the PN-EN-ISO-14122 standards.
Many years of experience in meeting individual needs, each time developed for a specific order, resulted in the development of unified modular blocks that allow very quick configuration for most cases that would be a design challenge for individual analysis and development. The concept of Walraven modular platforms includes several groups of basic functional groups, which, based on unified geometry and characteristic points, allow them to be freely combined into a configuration that fits into the provided "design" guidelines.

Why is it worth choosing modular communication platforms?
The final argument in favour of the modular approach to communication and service platforms is the possibility of delivery in prefabricated form.
The above arguments as:
- quick quote,
- detailed cost estimate,
- flexible adjustment to the actual situation.
It can be expanded to include further aspects related to the delivery, assembly and operation stages:
- adaptation of base modules to unexpected changes,
- possibility of delivery of ready-made modules,
- saving time, design, production and assembly,
- measurable financial savings,
- ease of assembly,
- resistance to weather conditions,
- adaptability to new functions,
- safe use of the roof,
- better environmental parameters due to fewer thermal bridges,
- very short implementation time (vs other solutions).
The possibilities of applying the modular platform concept can be presented in two basic cases:
- Comprehensive communication projects enabling access to multiple roof levels and passages over the facility's infrastructure elements,
- Individual local solutions for communication and access to devices,
Comprehensive developments usually include a “service path” concept that connects, for example, the roof entrance with a device that requires periodic servicing.
In this approach, between the beginning and the end of the path there are objects such as:
- Changing the height of roofs with attics,
- Passage over cable trays,
- Passage over ventilation ducts,
which must be overcome in a safe manner for the person performing the service but also without damaging these elements as well as the roof membrane.

Solutions may include access to the entire roof or to selected areas depending on the design guidelines adopted.
Local solutions often focus on a problematic location that requires a dedicated solution taking into account boundary conditions such as:
- Location of support points,
- Height/distance of accessible ground areas,
- Other location-specific requirements.
Possibility of modification in projects using Walraven
A significant group of solutions can be configured solely from ready-made modules, providing access to a given height, distance, etc.
In this case, the final solution is compatible with the base modules without the need for further modification.
More complex cases can be easily solved using 90% ready-made modules, equipped with specific elements developed individually for a given case.
The concept of modular communication and service platforms enables fast, reliable and cost-effective development of service paths on most facilities. Both for newly designed facilities as well as for modernization and expansion of functionality for existing structures. Solutions using Yeti® roof supports transfer loads in a way that is safe for the roof membrane, without the risk of damage due to the need for service technicians to move around roof connections.
In the event of a change in the concept related to the change of devices or their location, the adaptation of existing structures does not affect the roof layer, which is an additional economic advantage.
