The government has announced significant advancements in the building safety system, notably the appointment of an independent Chief Construction and Scientific Adviser, coinciding with the introduction of the Building Safety Levy.
Appointment of Chief Construction and Scientific Adviser
Professor Sergio Cavalaro, an esteemed academic at Loughborough University’s School of Architecture, Building and Civil Engineering, has been appointed to this newly established role for a three-year term. This position is strategically aligned with the wider network of scientific advisers across government, highlighting the crucial contributions of the construction and scientific sectors to the reform of building safety.
This appointment is part of the government’s response to the recommendations from the Inquiry report following the tragic Grenfell Tower fire in 2017, which claimed the lives of 72 individuals and revealed significant shortcomings in building safety regulations.
In his capacity as Chief Construction and Scientific Adviser (CCSA), Professor Cavalaro will provide independent counsel on matters concerning the safety, quality, and resilience of buildings, as well as on enhancing productivity within the built environment sector.
Commitment to Building Safety Reforms
Baroness Blake, the Minister for Building Safety, Fire and Resilience, expressed her commitment to prioritising the delivery of safer buildings and shielding residents from financial burdens. She highlighted the Building Safety Levy as a pivotal element of this initiative.
Baroness Blake stated, “I am also thrilled to confirm the appointment of the Chief Construction and Scientific Adviser – Sergio will play a vital role in shaping our reforms to ensure safety, robust regulation, and high standards are at the core of the built environment sector.”
Additionally, the CCSA will assist in implementing the remaining recommendations from the Inquiry and support regulatory reforms, acting as a liaison between the government, regulatory bodies, industry stakeholders, academia, and residents.
Collaborative Efforts for Building Safety
Professor Cavalaro will assume his new role on a full-time basis, collaborating closely with the Interim Chief Construction Adviser, Thouria Istephan, over the forthcoming month to facilitate a smooth transition.
Expressing his enthusiasm for the role, Professor Cavalaro remarked, “I am delighted to join MHCLG as Chief Construction and Scientific Adviser. I am committed to working with the Building Safety Regulator and across the wider sector to improve the safety, quality, resilience, and productivity of the built environment.” He also looks forward to providing independent advice and constructive challenges while contributing to cross-government priorities through the Chief Scientific Advisers’ network.
Implementation of the Building Safety Levy
In conjunction with this appointment, the Building Safety Levy, which imposes a charge on new eligible residential developments comprising over ten units, came into effect on 1st October. The revenue generated from this levy is intended to fund essential building safety improvements, forming a crucial component of the government’s strategy to ensure the industry plays its part in addressing building safety defects while protecting leaseholders and taxpayers.
It is projected that the levy will raise approximately £3.4 billion over the next decade, providing critical resources to eliminate hazardous cladding and safeguard residents’ well-being.
Endorsements and Future Directions
The updates provided today are integral to the government’s mission to enhance the building safety system, instilling confidence in the safety of residential properties.
Professor Dame Angela McLean, the Government Chief Scientific Adviser, congratulated Professor Cavalaro on his appointment, noting his leadership in scientific research pertinent to the built environment. She expressed anticipation for the collaboration within the cross-government network of chief scientists, emphasising the value of his expertise.
Lord Roe, Chair of the Building Safety Regulator, welcomed Professor Cavalaro’s appointment to this essential role, looking forward to engaging with him on the work of the BSR to leverage his extensive experience in the built environment.
Background of Professor Sergio Cavalaro
Professor Cavalaro holds a PhD in construction engineering and has a robust background in civil engineering. His extensive experience includes advising the government and industry on issues of national importance, alongside a deep understanding of regulatory systems both within the UK and internationally. Notably, he contributed significantly to the structural evaluations of Reinforced Autoclaved Aerated Concrete (RAAC), enhancing the sector’s knowledge during the COVID-19 pandemic and aiding in the national response. His leadership in collaborative initiatives has advanced modern construction methods, repair strategies, and quality control techniques, all aimed at improving safety, quality, and productivity across buildings and infrastructure.
