We brought BSE3D on board to help with our new office designs and planning reports, and honestly, the whole team blew us away. They’re not just experts - they’re genuinely enthusiastic and involved every step of the way. Everything they delivered was top-notch, down to the tiniest detail. Hope we get the opportunity to work with them again!

We work quite closely with BSE3D as a provider of ventilation equipment. BSE3D specify us where they can for their projects. Very professional company to be associated with, their engineers know what they are looking for and are happy to have suggestions made too.

I (as a team member of Bubble Architects) recently had the pleasure of working with BSE3D on a flatted scheme and I can confidently say their input and knowledge has been outstanding. From start to finish, their team demonstrated professionalism and expertise. They provided innovative solutions for mechanical and sustainable challenges the design team encountered during the project. The quality of their work is very good, and Mark Anderton and his team took the time to explain everything clearly and ensure the other disciplines were satisfied with the design. I highly recommend BSE3D for M&E engineering or Sustainability needs—whether it's for large-scale projects or smaller, specialized tasks.

Beckman Coulter have worked with BSE|3D for 4 years now and I personally have worked with BSE|3D during this time to successfully deliver numerous business critical projects. Beckman Coulter has a close working relationship with BSE|3D’s who have an open mind to new ideas/solutions, diligent approach to deliver cost and time effective solutions within their M & E designs for our projects.

Facilities Manager, Beckman Coulter

BSE3D were recommended to us by the former head of project management at Mace to advise us in relation to a number of areas relating to the Great Northern Hotel’s mechanical & electrical systems. Over a period of almost two years, BSE3D have helped us enormously through a combination of their vast technical knowledge and their ability to diplomatically drive forward our agenda without fear of upsetting the incumbent teams.

Chairman & Founder, RAM

Huge thanks and congratulations to BSE 3D on completing your recent cycle challenge. Most of you have been back already, and I hope you are starting to get over your jetlag and getting back to normality. It’s always a bit difficult settling into the swing of real life! I have had a report about the challenge from the local crew, whom spoke extremely highly of you all while on the challenge, so well done – you’ve also all done a phenomenal job raising funds for such a worthwhile cause!!!

Operations Manager, Charity Challenge

We have been delighted with the performance of BSE 3D. They were able to take our requirements, develop our brief and prepare a design all within a tight timeframe. They then tendered and managed the entire build process to budget. I would not hesitate to recommend them.

Facilities Manager, Holiday Inn Express

Our company employ many consultants, to develop design specifications and act as Lead Designer. Over the last two years we have worked together on a new data centre design. On a project of this size there are always areas to be developed and I was particularly pleased with BSE 3D’s response to any issues that arose by providing solution options and making sure the results matched our requirements. BSE 3D produced the Test Specification document used to test the full infrastructure and during the busy commissioning and test phase they were in attendance to witness and sign-off the test documents which confirm the test results fully meet the design standards and test specification.

Senior Programme Manager, Colt Data Centres

QData QFZ LLC hired the services of BSE3D for the MEP Design, Consultation and Supervision works of two Data Centers at the Qatar Free Zones of located in Ras Bu Fontas (capacity of 6MW) and Um Al Haul (capacity of 4MW), both of which were customized to the End ?User’s requirements and were successfully delivered. In addition to this, both Data Centers applied for Uptime Institute Tier III Certifications for Design, Construction and Operation in which BSE3D was also involved.

Both projects were well designed, executed and delivered within the agreed time-frame despite many challenges locally and internationally. BSE3D were a key figure in assisting and supporting us as a client to overcome all obstacles, leading to the success of both projects. Their performance and technical support were critical.

We would recommend BSE3D for future projects, given their commitment and their expertise in dealing with regulations within Qatar and the GCC region in general.

QData / Doha Venture Capital LLC

We at Colt have worked with BSE3D many times over the years and have always had a brilliant experience with them. The BSE3D team always go above and beyond to ensure designs and projects run smoothly.

In particular as an example; their assistance over the last 3 years on a complicated Generator and switchboard sequencing project has been brilliant. This project was a challenge due to the Data Centre being fully populated and live with customer loads but key switchboard and generator works needed to be completed seamlessly. They created the in depth design brief which was of a very high standard that allowed the project to be completed smoothly with no issues whatsoever.

They are a great team to work with and all members of the team have a very high level of technical knowledge and all work to a very high standard too.

Colt Data Centre Services

BSE3D have been an unbelievable find for Quantum Switch their contribution to our growth and success in expanding market places coupled with their diligent well experienced certified Data Centre professional engineers has made this possible. What we value most about our relationship is the personal service and technical knowledge available when required. We would have no hesitation in recommending BSE3D Limited for any type of Data Centre projects as long as it’s not in competition.
