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 巴特克格鲁特克S systems for precast column connections, Dextra ensured the structural integrity of this significant industrial facility.

 

巴特克, renowned for its mechanical splicing capabilities, and 格鲁特克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’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

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.
