The Commonwealth Heritage Skills Training Programme officially commenced at the Oak Ray Hotel, on Second Rajasinghe Mawatha, Kandy, led by the Vellore Institute of Technology (VIT), India, and the University of Peradeniya.
Running for six days from October 05 to 10, the programme brings together Sri Lankan heritage management professionals, architects, engineers, archaeologists, researchers, and conservation experts. It aims to strengthen scientific approaches to preserving historical buildings, bridges, and traditional construction materials across the island.
The participation of key national and international stakeholders highlights the programme’s significance in enhancing scientific knowledge, professional skills, and institutional collaboration for Sri Lanka’s heritage conservation.
Supported by the Commonwealth Heritage Forum UK, the initiative focuses on the scientific preservation of colonial-era structures and traditional materials, using the Mawanella Bridge as a primary case study. Built across the Maha Oya, between 1832 and 1833, the bridge serves as a vital component of Sri Lanka’s historical infrastructure and colonial engineering legacy.
Sri Lanka possesses a rich and diverse built heritage, encompassing ancient monuments, religious architecture, colonial buildings, historic bridges, and traditional construction systems. Beyond acting as physical evidence of the country’s history and cultural evolution, these structures form essential elements of the landscapes and places that define Sri Lanka’s identity. Consequently, their preservation holds value far beyond individual monuments. Safeguarding the authenticity, natural character, and integrity of historical sites reinforces cultural continuity for local communities while elevating the value of heritage destinations for domestic and international travellers.
In this context, the initiative provides a crucial platform for strengthening local professional capacities in scientific heritage conservation. By connecting Sri Lanka’s heritage managers, conservation architects, archaeological officers, engineers, and researchers with international academic expertise, it facilitates the exchange of practical skills and knowledge directly applicable to local heritage resources.
The programme emphasises understanding how historic structures were originally built, how their materials degrade over time, and how to design conservation interventions that ensure structural stability, while protecting heritage value.
Through lectures, technical sessions, case studies, and practical field demonstrations at the Mawanella Bridge, participants are introduced to methodologies for investigating historic brick and stone masonry, mortar, and other materials, assessing degradation, identifying root causes of damage, and selecting compatible repair materials. Special focus is given to common decay mechanisms such as cracking, mortar weakening, moisture ingress, salt-induced deterioration, and surface damage.
A foundational principle emphasised throughout the training is that conservation interventions must be rooted in accurate diagnostics rather than superficial damage symptoms alone. Furthermore, it highlights that heritage preservation is deeply linked to the long-term vitality of historical sites and surrounding communities. Well-preserved heritage structures can retain their cultural authenticity while serving as vital spaces for local residents, education, interpretation, and responsible tourism.
The programme is led by Prof. Thirumalini Selvaraj of the Vellore Institute of Technology and Principal Investigator of the Commonwealth project. She stressed the importance of adopting a scientific, evidence-based approach to the conservation, restoration, and revitalisation of historical structures and materials. As an expert in building biology and multi-scientific biological data analysis, she also highlighted the role of bio- and plant-derived materials in traditional construction and heritage conservation.
Dr. Selvaraj underscored the necessity of systematic documentation and digital technologies in heritage preservation. During her session, she explained how integrating 3D scanning, photogrammetry, and Geographic Information Systems (GIS) with scientific condition assessment enhances structural documentation, decay detection, and long-term monitoring.
Additionally, leveraging expertise in Artificial Intelligence (AI), she focused on potential applications of AI in evaluating and managing heritage structures, introducing how Large Language Models (LLMs) and other AI tools can be utilised for heritage documentation, knowledge management, and conservation efforts.
Led by VIT, this initiative bridges expertise across civil engineering, heritage conservation, architecture, building biology, materials science, digital technology, and artificial intelligence. Beyond technical training, the programme marks a significant step forward in strengthening India–Sri Lanka knowledge sharing in heritage conservation, opening new avenues for restoring Sri Lanka’s extensive colonial architecture and expanding its tourism sector.
