Collaboration Over Competition: The Power of the Supreme Solution for Precast Hybrid Connection

In today’s rapidly evolving construction industry, collaboration is key to delivering cutting-edge solutions that address the growing demands for efficiency, safety, and sustainability. This philosophy is at the heart of the collaboration between Dextra and Peikko, two global leaders who have come together to create a hybrid precast connection system that combines the best of both worlds: Dextra’s Groutec Couplers e Peikko’s Column Shoes.

This innovative system was successfully implemented in the Triumph Motorcycle Office and Factory project in Thailand, showcasing how collaboration can drive excellence.

The Hybrid Advantage

The hybrid precast system merges the strengths of column shoes and grouted sleeves to maintain the continuity of reinforcement in precast structures. This system has proven especially valuable in seismic zones and heavily reinforced elements.

Column shoes e Acopladores Groutec are well-known products used to create connections between precast columns. A combination of the two – referred to as ‘hybrid precast connection’ has been utilized in several markets, particularly those with seismic requirements.

From a structural viewpoint, column shoes e Acopladores Groutec are both designed to maintain the continuity of reinforcement through the joints of precast elements. In the case of heavily reinforced elements, it might be challenging to accommodate all necessary column shoes within the column cross-section. In such cases, combining column shoes with Acopladores Groutec may prove to be a cost-effective alternative.

With this solution, column shoes are intended to secure the stability of the column during the erection stage, while Acopladores Groutec complement the column shoes by transferring loads applied to the structure in the final stage. The term ‘erection stage’ refers to the stage when the joint has not been grouted, and ‘final stage’ refers to when the joint is fully grouted and hardened.

Column shoes enable precast columns to be erected without props or braces, which improves the speed of erection and allows for other construction activities to proceed unimpeded, as braces and props do not obstruct corridors, thus ensuring the continuity of the construction process without distraction. Groutec ensures rebar continuity at the “final stage” of erection.

Key Benefits of the System:

  • Faster Installation: Columns were installed without props or braces, reducing the installation time significantly.
  • Enhanced Safety: Eliminating bracing minimized site hazards.
  • Neat Finish: The method ensured a clean, professional result with no need for additional tidying.
  • Cost-Effective: Fewer materials and faster processes saved time and money. Groutec contributes reliable connections while saving costs on material and labor.


Triumph Motorcycles Office and Factory: A Case Study in Success

Completed in December 2024, the Triumph Motorcycle Office and Factory spans an impressive 89,077 sq.m and features 128 precast columns installed in a record-breaking time. Dextra and Peikko’s hybrid solution played a critical role in achieving these results.

This collaboration enabled Thai Obayashi, the project’s contractor, to achieve exceptional speed, safety, and quality.

 

A Future Built on Collaboration

O Triumph Motorcycles Office and Factory project exemplifies what can be achieved when industry leaders combine their strengths. As Dextra and Peikko, we believe that partnerships like ours are the future of construction innovation. Together, we can deliver solutions that exceed expectations and set new standards for the industry.

Let’s continue to lead through collaboration, making the construction industry stronger, safer, and more efficient for all.

Neo Factory Phase 1, Thailand

 

Neo Factory Phase 1, Thailand

 
 

Dextra has played a key role in the construction of the Neo Factory Phase 1 in Pathum Thani, Thailand, one of the country’s leading consumer product manufacturers. By supplying essential Bartec e Groutec S. systems for precast column connections, Dextra ensured the structural integrity of this significant industrial facility.

 

Bartec, renowned for its mechanical splicing capabilities, and Groutec S., designed for secure and easy installation of precast elements, were crucial in making the construction process efficient and reliable. Dextra’s involvement in the Neo Factory project underscores its commitment to providing high-quality, innovative products that support the demands of modern construction, contributing to the continued growth of Thailand’s industrial sector.

Jal Jeevan Mission Water Reservoirs, India

 

The Jal Jeevan Mission of the Government of India is a flagship initiative where attempts are made to ensure adequate supplies of quality drinking water at affordable rates on a long-term basis. It emphasizes the importance of proper water management, infrastructure development, and community participation to achieve the ambitious goal of ‘Har Ghar Jal’ (Water to Every Household).

Considering the widespread geography of India, uneven terrain, and human settlements in remote locations, access to continuous water is a challenge. Therefore, overhead tanks are a good option for efficiently storing and distributing water, particularly in areas with inconsistent water supply patterns. Construction and infrastructure development are yet another key factors that have a direct influence on development.

Precast construction is one such method that has gained tremendous momentum in recent times due to its advantages, such as accelerated productivity, better quality control, environmental friendliness, and optimized material and labor usage. Although this method incurs high initial setup costs, its attractiveness is enhanced by large-scale projects with standardized designs. In the project, our team worked in close coordination with Larsen & Toubro (L&T) from the design stage, carefully selecting Groutec and Bartec couplers to connect the H and U frames of the overhead tanks.

Our range of Groutec couplers is arguably the most reliable mechanical splices, specially designed to connect two precast elements with no requirement for in-situ wet concrete joints. These couplers have been successfully qualified and tested over the years on several major infrastructure projects, including process plant pipe racks, residential and commercial buildings, and data centers, among others.

 

Nestlé LEO Factory, Thailand

Nestlé LEO Factory’s reliance on precast elements necessitated a reliable, efficient method for joining the precast structure of the building. The construction utilized Groutec F, a well-known splicing system engineered by Dextra, to meet the exacting demands of the precast building. Groutec F allows for the connection of rebars without the need for bar end preparation and was used for the precast joint connection of beam and column in this project.

Groutec F is a fully grouted connection solution, ensuring robustness and durability in the face of dynamic operational environments. Engineered and manufactured in compliance with industry-leading standards such as Eurocode 2, BS 8110, ACI 318, IBC, and AASHTO, Groutec F guarantees adherence to rigorous structural specifications. It is compatible with major non-shrink grout brands readily available on the market, reducing logistical complexities and procurement lead times.

 

Uniqlo & Hive Indonesia Warehouse

 

Uniqlo & Hive Indonesia Warehouse

 

Indonesia’s building construction has spurred a need for rapid and efficient construction methods capable of meeting the demands of a burgeoning population. Precast construction has emerged as a solution to these challenges as it helps minimize on-site labor requirements, accelerates project timelines, and ensures consistent quality.

At the heart of successful precast construction lies the seamless connection between structural elements. Dextra supplied Groutec precast couplers for projects around the world, including Indonesia. Groutec in size 20mm were used in the Uniqlo & Hive Indonesia warehouse building project for joining precast columns, facilitating rapid and reliable assembly while ensuring structural integrity.

The couplers have minimized on-site labor requirements and accelerated project milestones. This not only translates to cost savings but also ensures timely delivery, allowing the building to fulfill its intended purpose sooner. Additionally, the couplers’ high-strength steel composition and stringent quality control measures guarantee robust connections that withstand the rigors of dynamic structural loads.
