Prefabricate Your Design & Calculation Process

'Prefabrication' is a word that has positive connotations, and rightly so. The word associates with quality, efficiency, innovation, and organisation. Prefabrication within the construction industry naturally makes you think of the construction phase of a project

‘Prefabrication’ is a word that has positive connotations, and rightly so. The word associates with quality, efficiency, innovation, and organisation.

Prefabrication within the construction industry naturally makes you think of the construction phase of a project. However, a major part in the overall project duration is the design phase, which tends to be around 40% of the overall project duration.

There are a lot of interesting and innovative approaches being taken in the construction phase of the project to cut time out of the program and to increase the quality of the installation. However, the design phase is lagging behind significantly on this front.

It is interesting and quite surprising to read that 32% of construction defects in buildings come from the design phase of a project. 3D drawing software programs indirectly have a major role to play in this.

The reality is that 3D drawing and coordination software programs are detrimental to the design phase if started and prioritised too soon. Unfortunately, this is often the case.

There is too much emphasis placed on minor components of each discipline looking pretty and coordinated in a 3D model long before it should be a priority. Focus is taken away from the system design and ensuring that the design is compliant, fit for purpose, and most importantly provides the best value to the client.

Providing a well thought through design takes the back seat; riding in shotgun is the pretty looking coordinated model.

Processes need to be incorporated into the design phase that tick the same boxes as ‘prefabrication’ – organised, quality, efficient, and innovative. The traditional process of drawing and measuring, inputting into various spreadsheets, looking up tables, and searching for manufacturer’s data online has become outdated.

At H2X, some of our core features, like pipe volume calculator, pressure drop calculator and Pipe Velocity calculator helps automate the tedious calculations that take up a significant amount of the engineer’s time and are susceptible to human error. By automating calculations, we are freeing the engineer’s time to focus on assessing and solving the fundamental design options that provide the best value to that project.

New call-to-action

In addition to that, we offer a platform that creates standardisation across the office and is very easy to audit internally or externally. This is an incredibly important part of the design phase that can often be overlooked or even rushed due to time constraints.

Having time to focus on the design rather than coordinating too early in the project will go a long way to decrease the 32% of defects that are attributed to the design stage.

Award-Winning Heating Design

"Using h2x was pivotal, allowing for precise heat loss calculations, pipe sizing and flow rates for each room.

This level of detail ensured that the heating load accurately matched each space's requirements, minimising energy waste and maximising comfort.

The strategic placement of heat pumps and careful sizing of pipework were crucial in maintaining minimal pressure drops over an 18-metre distance."

"I would estimate over the length of this project, I have spent 50% less time designing than I would on our previous software.

The ability to output the design straight into Revit assisted clash detection and coordination."

Salon Republic, USA

"The quality of the designs saw significant improvement with the adoption of h2x."

"The software offers precision through detailed result outputs and advanced options for efficient pipe sizing, allowing heating engineers to optimise based on parameters like maximum velocity and pressure drop."
