Design, documentation and digitalisation for telecom, power, water and gas networks, with project management at every stage.
Every network rollout follows the same stages, whether fibre, power, water or gas. We can take on the full engineering of the project or support your team at a specific stage.
Viable, buildable networks, designed with the site in mind.
Your external technical office to close out every project.
Your network information as reliable data.
Permits (street works, traffic orders and utility coordination) are currently offered for projects in Germany.
Alongside engineering, we have carried out civil works for fibre rollouts in Germany: trenching, ducting and surface reinstatement, including in historic town centres. That is why our designs start from the trench.




Fibre, power, water or gas: every linear infrastructure shares the same cycle of design, construction and documentation. Our experience comes from telecoms and applies to each of them.
We help you move from drawings, spreadsheets and manual processes to reliable digital information about your network: information you can consult, share and keep up to date.
From PDF drawings to a GIS network inventory that anyone in your organisation can consult. With the network as built, not as designed.
We move your network information from one system to another without losing it on the way: from CAD or legacy platforms to your current system, or between different operators’ formats.
Software for day-to-day project work, adapted to the way you work and connected to the data you already have.
We identify the processes that take time without adding value and replace them with AI-based tools.
We identify the processes that take time without adding value and replace them with AI-based tools tailored to the way you work. We run our own company on tools we have built: contract generation, invoicing and reporting, and our own CRM.
We connect the right companies in the German network sector and support subcontractors who want to work there or grow their business.
For companies in Spain working with German clients. We act as your project manager and are your face to the client, in their language.
CAS Telecom is an engineering and consulting company based in Seville, specialised in the deployment of infrastructure networks. We started in telecom network rollouts, including more than five years of FTTH projects in Germany, and now apply that experience to infrastructure projects in Germany and Spain.
We design with the builder in mind, because we have built too.
Years of projects in Germany, working in Spanish, German and English.
One contact person for the whole project, from start to finish.
Our own tools and artificial intelligence to work faster and with fewer errors.
