What is quality control?

Quality control ensures that completed work meets the expectations agreed upon at the outset of a project. Whilst sometimes used interchangeably, quality assurance and quality control are separate terms:

  • Quality Assurance (QA): Refers to quality management assumptions and how these will be achieved.
  • Quality Control (QC): This concerns the plan and procedures you will follow to achieve high-quality outcomes, which are present throughout all phases of the project. Some methods of QC could include employing a quality management system (QMS), statistical process controls (SPCs), or efficiency-driving software.

Why quality control in engineering matters

If quality control requirements are not met, projects often face complications:

  • Added costs: One study suggested that construction project design errors resulted in direct costs roughly equal to 6.85% of the contract valuewithout proper quality control, costs can quickly escalate.1
  • Safety issues: Incorrect pressure and velocity measurements can result in dangerous system failures.
  • Damaged reputation: Systems that don’t work are evidence of design failure. Not only is this damaging to the engineer’s reputation, but it is also damaging to the company.

Quality control improves client satisfaction, meaning the engineer is more likely to receive future work. 

Moreover, high-quality work can prevent rework times, which:

  • Reduces costs
  • Ensures your project remains on schedule
  • Keeps your team’s morale high
  • Boosts productivity

Remember, quality control and cost control are not mutually exclusive. When you plan and establish quality standards early on, you can substantially reduce the risk of mistakes, and their associated cost, further down the line.

 

Designing and calculating

Traditional design and calculation methods can be incredibly tedious. They typically involve markups, rulers, and transferring data to and from Excel, while continually sharing this information with other team members.

This design and calculation method puts several aspects of quality control at risk. Leaders may lack visibility of what changes are being made, and, in the process, lose track of their team’s progress. This can result in:

  • Abandonment of procedure: when visibility is lost, the next thing to go is almost always procedure. Team members might begin using informal calculation methods, exposing their designs to the risk of error.
  • Human error: just one mistake can have a catastrophic effect on a project, multiplying across the system design and leading to poor quality, and potentially dangerous results.
  • Time-consuming amendments: particularly if a design or calculation error occurs at the start of a project, it can take a long time to locate and resolve the issue.

h2x and compliant design

With h2x, this entire process is simplified. It allows users to easily calculate their system’s velocity, pressure and flow rates, ensuring compliance is maintained at all times. When using h2x, all a user has to do is:

  1. Input their design parameters
  2. Develop their design by inputting pipes, nodes, vents and more
  3. Review their results, adjusting the design according to design warnings

 

By eliminating the risk of human error, h2x allows engineers to save time, reduce costs, and produce high-quality designs.

Iterating the design

Iterations are an inevitable stage of any systems engineering process. Whether due to changing client specifications or architect redesigns, they can make it difficult for engineers to keep costs low, while maintaining design quality.

In traditional designing methods, engineers are faced with only two iteration options:

  1. Start the design process again.
  2. Be conservative in initial calculations, so that changes can be made more easily later on.

Neither of these solutions is perfect. The evolution of design iteration demands engineering processes that can cope with constant change, development, and adjustment. 

h2x: making iterations easy

Made by engineers, H2X is designed to make iterations quick and easy.

After receiving an iteration, all an engineer has to do is change the design layout, which will instantly update the system calculation results.

Without going through the tedious and often repetitive process of designing and redesigning, engineers have more time to focus on the quality and efficiency of their systems. 

 

Performing internal reviews

Performing internal reviews is an easy way to ensure quality control is maintained. Depending on the length of the project, teams might choose to take weekly, monthly, or six-monthly reviews, which allow team leaders to assess whether the quality of the work is meeting internal and external targets.

However, there is a right and wrong way to perform these reviews. Some common issues internal design reviews face are:

  • Lack of clarity: multiple versions of designs across different devices can make it difficult for teams to correlate inputs and results between spreadsheets and the design markup.
  • Simple mistakes: if designs are harder to access and review, final system designs will be more prone to error.
  • Miscommunication: if clear communication channels are not established early on, internal reviews will be governed by miscommunication, confusion, and potential conflict.

h2x and the review process

h2x is, first and foremost an engineering design tool made to ensure the quality, compliance, and accuracy of engineering work. 

However, it is also defined by its focus on collaborative working. 

h2x offers a CIBSE calculation software that helps to ensure consistent outcomes across teams. Results are shown on each component, and the calculations can be viewed for additional clarity.

With h2x, internal reviews can be managed more efficiently as lead engineers have direct access to their team’s designs, results, and calculations. Not only can this help prevent miscommunications and errors, but it can also help quality control procedures function more effectively.

 

Performing external reviews

Like internal reviews, external reviews are essential to maintaining quality control and ensuring that clients are happy with the progress of their design.

Typically, an external review process might look something like this:

  1. Send an excel file to a customer via email.
  2. Receive a response or multiple responses asking for more information.
  3. Respond with information, or amend the design according to client requests.
  4. Organise a face to face review or undergo a written review procedure.

It’s not uncommon for engineers to receive several requests for information (RFIs), meaning more time has to be spent sending documents with updated versions.

Although excel files may seem easy to understand for engineers, this is not always the case for clients. User-friendly and easily shareable designs are essential for improving customer-engineer communication and, in turn, improving quality control measures.

Improve customer satisfaction with h2x

h2x simplifies the process of external review by eliminating the need for RFIs. Customers can easily view the live design, as well as the calculations behind it; as a result, the external review process will look more like this:

  1. Notify the customer that their design is ready for review.
  2. The reviewer views the design, and gains a clear understanding.
  3. There are little to no RFIs because the reviewer can see the calculations have been undertaken to a high level of detail, with the accuracy verified by CIBSE.

With a user-friendly and visually impressive interface, customers can get a real idea of what their design will look like. They can offer more high-quality feedback that allows the final product to be delivered more quickly.

Getting consistent outcomes

Getting consistent outcomes is no easy task when working within a diverse engineering team. Each team member will have their own processes, methods, and standards, making it difficult for lead engineers to present work to clients in a uniform format. 

Though it might not be detrimental to present clients with inconsistently formatted files, it can reflect badly on the processes within your organisation.

Furthermore, inconsistent outcomes can make parts of quality control more difficult to follow, as team members alike struggle to follow the same processes in different programs.

h2x: Live, consistent designs

From calculations to exports, h2x allows engineers to ensure consistency across the board. This helps to:

  • Maintain quality control with uniform calculation and design procedures.
  • Improve communication across the team.
  • Impress clients with easy-to-understand layouts and process improvements.
  • Make it easier for clients to assess their designs.

 

Collaborating with your team

Collaboration and quality control are two sides of the same coin — quality control in engineering cannot be effective if there’s no clear communication on policy, compliance and team expectations. 

But with engineering turnover rates and skills shortages high, it’s important that collaboration isn’t just with your existing team, but with the team you expect to have in a year’s time.2

When a team member joins or leaves their company, lead engineers need to ensure that projects can continue to run seamlessly. The first step to improving the productivity of your engineering team is enabling long-term collaboration.

h2x and collaboration

Technology can enhance quality control management and monitoring by offering features such as automation, accessibility and visibility.

h2x simplifies the process of employee handover by holding designs within a shared, consistently formatted database. It becomes easier to train new employees according to straightforward and uniform processes, and keep track of when projects were last edited. 

If a team member leaves, it is easy for another engineer to pick up and continue the project without expensive rework.
