Taking NextGen Further: Working with Educators and Policymakers

Why We Expanded the Program

After reviewing the progress of the NextGen Engineering Program, we came to a simple conclusion: direct training is valuable, but it can only reach a limited number of people at one time.

If we want knowledge to remain useful for many years, we must also work with the people who teach future civil engineers. Lecturers can adapt what they learn, use it in their classes, and pass it to new groups every year. Government officials and professional engineers can carry technical knowledge into industry discussions, public requirements, and future policy decisions.

VCON therefore expanded NextGen in 2025 to include civil engineering lecturers, government officials, and members of Thailand’s professional engineering community.

Amplify Knowledge Through Educators

Strengthen Policy and Public Impact

Advance the Professional Engineering Community

Empower lecturers to bring new knowledge into the classroom and inspire the next generation of civil engineers every year.

Equip government officials with technical insights to support evidence-based decisions and future policy development.

Engage professional engineers to apply knowledge in industry practice, standards, and national development.

Building Tomorrow, Sustainability

American Concrete Institute Standards

Precast/Prestressed Concrete Institute

CIVIL ENGINEERING LECTURERS TRAINED IN 2025

The training covered Building Information Modeling (BIM), low-carbon construction, American Concrete Institute standards, and practical knowledge from the U.S.-based Precast/Prestressed Concrete Institute.

We selected these subjects because they connect classroom learning with the way modern construction projects are designed and delivered. BIM can help project teams coordinate their work, identify design conflicts before construction begins, reduce errors, and use materials more efficiently. ACI and PCI knowledge gives lecturers international references for structural safety, concrete quality, precast manufacturing, and prestressed-concrete applications.

Our role was not to rewrite or control the institutions’ formal curricula. Instead, we shared technical content, examples, and industry experience that lecturers could use to enhance what they already teach. Each lecturer can decide how the material best fits their courses and the needs of their learners.

Building Tomorrow, Sustainability

Reaching Beyond Bangkok and Beyond Universities

Training Locations outside Bangkok in 2025

In 2025, we made a deliberate effort to bring more training outside Bangkok.

Activities were held at Naresuan University in Phitsanulok, Thanyaburi Technical College in Pathum Thani, and Chonburi Technical College.

We also expanded our focus beyond

Naresuan University in Phitsanulok

universities because technical colleges are closely connected to Thailand’s construction workforce. Their educators

prepare people for practical roles in construction, production, drafting, site supervision, and related technical work.

Universities develop engineers, researchers, and designers, while

technical colleges prepare people who often apply construction knowledge directly on projects and in factories.

Working with both types of institutions allows NextGen to support a broader part of the profession and make BIM, international standards, and sustainable construction knowledge more accessible outside Bangkok.

Working with Government and the Engineering Profession VCON also trained a combined total of 48 government officials and engineering professionals through the Department of Public Works and Town & Country Planning and the Thailand Structural Engineers Association.

The sessions covered structural safety, BIM, low-carbon materials, precast and prestressedconcrete technology, and international engineering practices. We used practical examples to discuss how these approaches can contribute to safer buildings, more efficient construction, and lower environmental impacts.

The Department of Public Works and Town & Country Planning has an important role in Thailand’s construction and planning environment. Giving official access to current technical knowledge can support more informed discussions about public requirements, construction standards, and future regulations.

The Thailand Structural Engineers Association connects NextGen with practicing engineers. Its members can carry relevant knowledge into projects, professional networks, technical discussions, and continuing professional development.

We do not suggest that one training session will immediately change a regulation. That is not how policy develops. Our aim is to make practical knowledge available to people who participate in those discussions and decisions.

Turning Training into Measurable Impact Because the expansion to educators and policymakers began in 2025, it is too early to assess long-term changes in teaching practice or regulation.

We can, however, report what has been delivered and establish a clear framework for measuring future outcomes.

For 2026, we have established the following targets:

80%

At least 80% of trained lecturers will apply one or more NextGen topics in their teaching.

18

At least 18 existing courses or teaching modules will be enhanced with BIM, ACI, PCI, or low-carbon construction content.

3,000

Lecturer-led teaching will reach at least 3,000 people.

85%

At least 85% of participating educators and officials will report improved knowledge relevant to their work.

2

At least two follow-up technical sessions will be held with government or professional partners.

We will track these results through lecturer surveys, course-material reviews, institutional confirmation, attendance records, and partner feedback.

For VCON, success will not be measured only by attendance. It will be measured by whether lecturers continue teaching the knowledge, whether professional engineers apply it, and whether government partners use it to support better-informed discussions and decisions.

By working with educators, government officials, and professional engineers, VCON is helping knowledge travel further than we could achieve alone.

The use of low-carbon cement has also improved the environmental performance of VCON’s manufacturing operations. With precast production taking place in controlled factory settings, the integration of greener cement contributes to lower energy demand, minimized material waste, and more efficient curing and handling processes. These benefits compound across the construction cycle, reducing overall site emissions and helping to accelerate clean, precise installation at the project level.

This collaboration also reflects a shared commitment to long-term sustainability. Siam City Cement’s Sustainability Ambition 2030 outlines a bold framework focused on climate action, circular resource use, and environmental stewardship values that strongly align with VCON’s own sustainability roadmap. By working together, the two companies are advancing Thailand’s climate goals while setting a new benchmark for carbon-conscious construction across the region.

In today’s rapidly evolving construction landscape, VCON’s partnership with Siam City Cement demonstrates how deep, technical collaboration can lead to real environmental impact. Through this integration of low-carbon cement into precast systems, VCON is delivering not only efficient and reliable building solutions, but also contributing meaningfully to the future of sustainable infrastructure in Southeast Asia.
