To whom it may concern,
My team first engaged Tetris Group in 2021 after we were having delivery issues in NSW with previous suppliers in respect to design and execution. The first project involved finalizing our internal concept by conducting a detailed site survey, then producing a 3D model of the new Crusher, Grizzly plates, support steel, and conveyors. The project was modelled, fabricated, and installed on time with zero safety issues and within budget.
Following the success of this project, we then contracted Tetris Group to complete additional major components over the following three years through their mechanical and electrical divisions in QLD and NSW.
I would highly recommend the team at Tetris Group for large, medium, and small projects. They have a professional team of engineers, draftsmen, and highly skilled tradesmen. Their attention to safety and quality is consistent with the highest standards we’ve come to expect. Our plant is now up and running, and the maintenance team continues to use Tetris Group for day-to-day projects, shift coverage, and fabrication works in NSW and QLD.

To WHOM IT MAY CONCERN
I have been working with Tetris for over five years. During this time, they have demonstrated a deep understanding of our engineering issues and used it to provide innovative and cost effective solutions ranging from finding highly abrasion resistant materials to providing specialised skills for time critical repair jobs.
They have assembled a dynamic team with a “can do” attitude and Tetris have become a strategic partner for my engineering team. They are responsible for all steam system maintenance for our mill and are a major resource for other shutdown maintenance and Project activities.
Tetris have used their extensive network and industry knowledge to become a major solution provider and are our “go to” people for a number of engineering and project related issues.
I will recommend Tetris to anyone looking for innovative engineering solutions in manufacturing environment.

BOC engaged Tetris Group PLC as main contractor to undertake installation works of the recently completed Automated Sort & Pick System at our Wetherill Park Facility in Sydney. BOC held responsibility for delivering the initial Prototype System, Phase 1, under the close supervision of Cimcorp OY.
Tetris Group PLC provided all technical trades, tools and heavy lifting equipment to BOC for the duration of this highly challenging project. The scope of supply for Tetris Group PLC was as follows:
Following the successful implementation of Phase 1, BOC had no hesitation in once again engaging the services of Tetris Group PLC to assist with implementation of Phase 2 of the project, a scope which was almost double Phase 1. Tetris Group PLC management worked closely with BOC to ensure OH&S processes and procedures were followed without exception. The result for all parties involved was a highly complex system completed without incident on time to budget within a major operating hazardous facility.
BOC commends Tetris Group PLC for their professionalism in completing this project without incident and would have no hesitation in recommending them to prospective customers.

To whom it may concern,
The purpose of this letter is to give reference to the excellent quality of welding of the repairs and the replacement LP pipe work done by the company Tetris Group, who work at 13-15 Somerville Circuit, Emu Plains NSW 2750.
I was engaged by Visy as a technical welding expert regarding the recent Visy boiler shut down at Visy works, 13 Reo Crescent, Campbellfield Victoria. The work I refer to was the removal and the replacement piping, which was thermally post-weld heat treated and 100% radiography of all the joints revealing nil repairs.
The Tetris team carried the bulk of the welding and the repair of a Hora reducing Valve at their works. All the welding was done using the GTA W process with great care and attention to preheating carried out.
The quality of the welding was of the highest standard to match anywhere in the world. The traceability of the welding consumables and the pipe work was done in a very professional manner leaving no room for errors.
By way of this reference based upon this recent repair and replacement exercise I have to commend the Tetris Group for the quality work they did under the pressure of Visy to get the boiler back on line.

To whom it may concern
I am writing to commend the Tetris Group for their exceptional work on the major repairs of the Evaporator at the boiler in VP8, Brisbane. Their performance throughout this breakdown was exemplary and demonstrated the highest standards of professionalism and expertise. From the outset, the Tetris Group exhibited outstanding planning, coordination and execution. Their meticulous approach to planning was evident in every aspect of the project.
The job began as a breakdown with a tube leak and quickly escalated to a major repair with multiple tubes needing to be replaced due to the number of tubes that had reached end of life. The Tetris team quickly pivoted and resourced adequately to ensure the plant downtime is minimised. The team faced significant challenges due to access restrictions and the necessity to cut tubes to access the section of tubes that were failing. Despite these obstacles, the Tetris Group executed the job to perfection. The team meticulously performed multiple welds, ensuring each weld met the highest quality standards. The fact that the repairs passed hydro testing, with zero failures, is a testament to their exceptional skill and attention to detail.
Furthermore, the reporting, documentation, supervision, and execution of the works were conducted to an exceptionally high standard. The Tetris Group's commitment to maintaining thorough and accurate records, coupled with their diligent supervision, ensured that the project was executed flawlessly. Their documentation included detailed daily progress reports, weld maps, and inspection records, all of which were completed to an industry-leading standard.
In my experience, their level of professionalism and quality of work is unparalleled in the industry. The Tetris Group completed the project within the scheduled timeframe and under budget, demonstrating their efficiency and cost-effectiveness. I have no hesitation in recommending the Tetris Group for any future projects. Their dedication to excellence and their ability to deliver outstanding results make them a valuable asset to any team.

This letter shall serve as a recommendation to employ TETRIS GROUP PTY, based on their work history within the Visy Cogen Facility in Coolaroo, Victoria and at Pratt Industries Facility in Conyers, Ga.
Since 2012 Tetris has performed modifications to the Coolaroo Boiler as well as emergency repairs. Their work includes:
1. Superheater replacement in TP310S. Difficult material to weld and they were on budget and on time with no weld reject from radiography.
2. Increased Fuel Feed opening in the boiler. This required demolition and rebuild of the opening to a larger size using offset tubes. This job was on time and on budget.
3. Added 26 combustion airports to the boiler. This job was on time and on budget.
4. Tetris has made numerous repairs to the unit. In which all passed radiographic examination. Their work was completed timely and economically.
Since 2012 Tetris has performed extensive modifications and repairs to the Boiler in Conyers, GA. Their work includes:
1. Replacement of all superheat tubes on the entrance and exit of superheaters 2,3 & 4. Using TP310S.1000. The work was done on time and on budget.
