Building Services- Detailed Design

Plumbing Design

Sanitary Design

Sanitary drainage systems need to minimise risk of blockage and still be ventilated properly to external atmosphere.

With accurate demand calculations we then specify equipment, stack and branch pipe runs and provided full 2D or 3D spatial drawings if required.  This can save in reducing amount of soil and ventilating stacks and ease the routing of other services. 

Compliant design results in quick approval at building warrant stage and when applying for utility connections. It can also save money in installation costs. 

Surface Water Design

Rainwater is generally collected and passed to surface water systems with gutters and rainwater pipes. 

The sizing and determination can need special calculations especially for larger buildings or for aiding in recycling systems.

"Designing for summer storms creates a few surprising figures. For instance, summer rainfall in London is nearly twice as heavy as in Glasgow. Generally the southeast of England has the heaviest rainfall; the further north and west you travel in the UK, the more design rainfall decreases"


Independent Service Engineers

How We
Can Help

Traditionally heating/services were a standard work package handled by the trades and architects but buildings, regulations and the needs of the client have become more complex over time, and rightly so. Heating is integral to the comfort and well-being of your home/work and is only now been given proper consideration in the build. Also, often it can have the largest impact on operating cost for you in terms of bills and carbon impact over the long-term. In addition, there are a multitude of options available with renewable technologies in a fast-changing market. There can be a considerable cost benefit to have input from specialist independent building service engineers at several stages.
