The phases of planning
Basic analysis
In the HOAI, this phase is only available as an preliminary work. Requirements are determined here. At this point you should find a team that understands your project. We like to say, “Form follows function”. This phase is very important in order to get to know and shape your vision.
Planning
The vision turns into a construction project. But only in draft form. If you do not plan carefully with a sense of craftsmanship you will definitely get some problems later. Maybe at terms of awarding, concrete implementation, time or even the budget. These three phases are usually summarized under the term design: Depending on what kind of project, now it is our internal planners and/or architectural firms and specialist planners turn.
Permission
Whether it's a conversion, extension or new building: It's time to get approval from the authorities. We have persons authorized to submit building proposals who can now also submit the design but we also hand it over to architecture or planning firms at work phases 5 to 7.
Execution
Implementation planning starts. Dimensions and properties should be determined. It is also about tendering practices set by the client. As a general contractor we can lead to very pragmatic solutions during this phase. Depending on the construction site, individual structures result in different ways, which can lead to enormous complications in phase 8.
Construction supervision
This phase is generally referred to as "construction management" but actually "property supervision" is the correct term. It is about coordinating the trades and meeting time and financial goals. Especially for architecture firms from other federal states who need a company in Rhineland-Palatinate or Saarland for complex construction projects, due to our own craftsmanship expertise and market knowledge in the craft sector we are a reliable cooperation partner.

Realised together
In a Europe-wide architectural competition, our client, DBCO from Münster, prevailed against around 80 applicants. We had the privilege of accompanying the winning design as a local construction manager. Despite challenges such as corona, supply bottlenecks, steel shortages and the effects of the Ukraine war, the construction site never stood still in the years 2021 to 2023. The combination of glass, wood and concrete as well as the curved elements also made this project particularly demanding in terms of craftsmanship.


Alugas Bad Sobernheim
On behalf of Novocont, we have planned a comprehensive expansion of the area. As a result of this measure and the construction of a tent hall, including new paving areas in-house and planned the roof of a degassing plant, this project was sustainably functionally and usefully optimized.
