Construction

Conduct site inspections to check the construction quality of contractors:Throughout the construction process, environmental monitoring is performed at each stage, and site inspection frequency is supervised and documented according to regulations. Inspection records are documented on a project-by-project and personnel basis on the construction team’s high-level inspection webpage, ensuring that inspections are conducted frequently. Issues identified during inspections are promptly reviewed, corrected, and coordinated, with follow-ups to track project execution.

Construction Traceability Record:Each of our projects includes a “construction history,” which serves as an important proof of material quality provided to customers during the handover. The history includes details such as third-party testing reports, the types and frequencies of tests, and sample inspection standards (e.g., radiation-free steel bars, chloride content in concrete, tensile strength of steel bars, concrete compressive strength, steel bar coupler pull tests).

According to a 2021 International Energy Agency report, the building sector accounts for approximately 38% of global greenhouse gas emissions. Greenhouse gas emissions throughout the building lifecycle include both “operational carbon emissions” and “embodied carbon emissions.” Operational carbon emissions during the daily use phase account for approximately 28%, while embodied carbon emissions during construction and renovation/demolition phases account for approximately 10%. In response to Taiwan’s 2050 net-zero emission pathway and strategy, it is projected that by 2050, 100% of new buildings and 85% of existing buildings will need to be transformed into “near-zero carbon buildings.”

To reduce energy consumption and carbon emissions in buildings, Ruentex Development has made “green building” and “environmentally friendly materials” key design elements. This approach aims to reduce energy use and carbon footprint, optimize the utilization and management of buildings and resources, and improve the quality of both indoor and outdoor environments, thus minimizing negative environmental impacts and contributing to sustainable development. Over the past decade, all of Ruentex Development’s buildings have been designed to meet the Silver-level Green Building Label standards. Starting from 2024, all new buildings by Ruentex Development will apply for green building certification, and all commercial projects will obtain intelligent building certification, with Ruentex Yucheng Office Building additionally applying for diamond-level intelligent building certification. 

Precast Construction Method
The vast majority of work items originally performed on-site are moved to the factory, including main structural components such as beams, columns, and slabs. Compared to traditional on-site construction, this method significantly reduces labor and construction time costs. Additionally, precast products have a high degree of completion, minimizing the need for scaffolding and temporary supports, eliminating the need for surface finishing, and allowing for mold reuse. This method also helps alleviate labor shortages, promotes environmental sustainability by reducing carbon emissions, and shortens construction periods.
First, second, and third-generation technologies have been developed, with 11 new patent applications submitted.
This method involves using a propulsion device to shape steel bars into spirals. Multi-spiral stirrup columns have excellent seismic performance, can replace traditional square stirrups with 50% less stirrup usage, increase column deformation resistance by 60%, reduce on-site stirrup work hours by 70%, and help reduce carbon emissions.
This method has already been applied on construction sites.
Aluminum templates are stronger than traditional wooden templates. In addition to being reusable multiple times, they have several positive characteristics: they do not absorb water, which helps maintain the concrete mix ratio, the metal surface is smooth and easy to demold, they are non-flammable, and have high residual recycling value. Therefore, after the mold is removed, there is no need for traditional masonry work, saving labor, improving construction quality, and reducing carbon emissions.
This method has been applied on construction sites, with 10 new patent applications submitted.

A structural system composed of reinforced concrete columns and steel beams, where the beam-column connections in the structural system use steel-reinforced concrete composite joints. The application advantages include not only the benefits of general precast methods but also maximize usable space due to different structural design, with more attractive appearance than general precast components.

Compared to traditional SRC, it can reduce the use of high-carbon column steel and pre-cast beam-column connections, not only reducing construction interfaces but also significantly shortening structural construction periods. With smaller phased construction intervals, it can shorten the startup time for work item interfaces, reduce on-site construction work, and lower construction site carbon emissions.

The PCS method has obtained recognition from the Construction and Planning Agency as "New Construction Technology, New Methods, New Equipment and New Materials," and was used in the "Ruentex Yucheng Section Commercial Building New Construction Project." This project also obtained "Seismic Design Certification" from the National Taiwan University Earthquake Engineering Research Center,  and added one new patent application.  National Center for Research on Earthquake Engineering
