Diseno – Designing More Competitively with Trimble

Based in Bangkok, Thailand, Diseno Co Ltd has over 10 years of experience, proving their BIM capabilities throughout a varied range of projects involving different types of structures. As Thailand’s design and build industry continues to move towards BIM, their adoption of Tekla Structural Designer made perfect sense – recognising the solution’s ability to seamlessly integrate into their BIM processes as well as to provide key competitive advantages for the young firm.


As per the industry norm, Diseno Co Ltd works with a number of diferent BIM software and tools for a single project throughout its design life cycle. Their decision to add Tekla Structural Designer (TSD) to the mix was primarily to realise greater productivity, improve interoperability, and to lower the occurrence of clashes during the modeling stage.

While having only adopted TSD recently, its ease of use has proven itself within a few short months, with the team’s junior designers being able to quickly master and utilise the software efficiently. One aspect that the team has banked on for TSD to deliver has been to execute structural designs quickly and accurately. TSD is used to model, analyse, design, report and generate drawings.

For Diseno, integration tools are essential to implement the BIM process throughout a project’s lifecycle. Trimble’s integrator tools were perfect for its ability to spot and fix clashes on every single element – from jointings, boundary elements and analysis errors. Models are initiated in TSD, are easily validated, and can be seamlessly passed to other BIM software. Drawings can then also be generated from TSD, saving time for the team.


One project where TSD proved its worth was the Nikkei Siam Aluminium Limited Warehouse. Diseno’s involvement was to provide structural engineering and
to be the BIM-engineering operator. The main challenges for this project were in terms of time and cost, with only approximately 5 months for the entire project duration.

With the structure made up of concrete and steel, during the design phase, TSD was used to estimate materials and optimise the design output. Models were initiated in TSD for design and calculation, before they are handed of to another BIM software to add architectural and piping details. TSD was then used to create the assembly
drawings that were sent to the CNC machining and fabrication processes. During the construction phase, TSD once again proved highly useful, with its ability to generate shop drawings.

In its 10 years of operations, Diseno are no strangers to the various software tools for structural design. One of the main issues has always been interoperability between software programs, many of which claim to easily integrate with others but in reality, fall short. For the Diseno, one of TSD’s greatest comparative advantages is in its ability to easily move a model to a BIM software program, and to pass it back to make adjustments, while sharing it with other stakeholders throughout the design process. “TSD comprehensively supports almost all the general requirements of BIM for structural design, and the integration tools ensured that we do not have to worry about matching quantities take-of. TSD also allowed for quick revisions and optimisation, and with the short learning curve of the software, we are convinced that it is the ideal software for our needs,” said Panithi Brahmasakha, Chief Executive Officer, Diseno Co Ltd.



Diseno were the structural engineers, structural designers, as well as the BIM operator for two other notable projects employing Trimble Solutions – the Garage Studio and Chememan Public Company Limited Quick Lime Plant Extension.

For both projects, the key priority and challenge was to be highly competitive and nimble in the area of cost controls throughout the design stage. This required a fast, highly efficient and accurate design process, with both projects having a tight 3-month design stage.









TSD was used alongside an industry standard BIM application to achieve the required results – with TSD providing the team the ability to quickly resolve clashes and errors between structural and architectural models as well as to provide early quantity reports. This provided the clients with information on incoming costs quickly.
Alongside TSD, Trimble Connect and Trimble Sketchup were also used to ensure inter-communication and updates between other stakeholders were as seamless as possible. TSD models were easily transferred to Sketchup to visualise the models in 3D, which helped the team to effectively collaborate with the client and contractor during team meetings.












TSD’s value to the team has been an eye-opener for us – allowing us to solve many typical design development processes with BIM integration problems and producing optimised models for each specific requirement. TSD proved more than capable for the structural design process with its high compatibility models, and even in the conceptual stage, allowed us to accurately estimate real quantities and costs required for the construction stage. The information provided by TSD went beyond just accurate analysis and design. The time savings proved to be invaluable especially where lean costs were critical. The TSD models also provided highly accurate information for all parts of the building, down to the tiniest detail, something which the customers really appreciated.
