Practices HLM and Stride Treglown behind trio of shuttered schools break silence as government launches investigation into collapsed contractor

The architect behind two of the schools closed due to structural defects left the projects because of concerns it had with contractor Caledonian Modular, 好色先生TV can reveal.

HLM said it developed a 鈥渘umber of concerns with Caledonian鈥檚 approach鈥 as the projects progressed and parted ways with the firm as it was 鈥渦nable to resolve [its] differences鈥.

Sir Frederick Gibberd College in Harlow

Original designs for Sir Frederick Gibberd College in Harlow were drawn up by HLM, which said it left the project due to concerns with Caledonian Modular

The practice was the design architect for the 1,200-place Haygrove School in Somerset and the 630-place Sir Frederick Gibberd College in Essex, which have been advised not to reopen for the autumn term by the government.

A third school built by Caledonian Modular, the 50-place Buckton Fields Primary School in Northampton, has also been advised to close because of similar structural issues.

Yesterday the Department for Education (DfE) said it had launched an investigation into Caledonian Modular and had warned other government departments about issues with the firm, which also worked in the residential sector before its collapse in 2022.

The department blamed poor workmanship for the closures and said technical surveys of the three schools had found fire safety issues and a weakened ability to withstand high winds or heavy snowfall.

Philip Watson, head of design at HLM, said: 鈥淗LM Architects were initially employed by Caledonian to design Sir Federick Gibberd College and an extension to Haygrove School. 

鈥淎s these projects progressed, we began to have a number of concerns with Caledonian鈥檚 approach to the technical delivery of the design to meet the DfE鈥檚 high quality output specification. 

鈥淯nable to resolve our differences, we parted company with Caledonian and the projects were delivered by others.鈥

Watson added: 鈥淚t鈥檚 a great shame that these schools have not been realised in the way that the DfE intended, and we hope the impact on staff, pupils and the communities in which these schools sit, can be minimised.鈥

The DfE has confirmed that the schools, which were all completed between 2020 and 2021 using a modular approach, had not been built in accordance with the design so could not be assured as safe to occupy.

Caledonian Modular built all three schemes through the government鈥檚 拢3bn modular schools framework, which launched in early 2020.

The firm remarked at the time that it would use offsite completion to 鈥渞educe risk, save time and optimise speed and efficiency of school design and delivery鈥.

HLM, which was named 叠耻颈濒诲颈苍驳鈥檚 architectural practice of the year in 2022, said it does not believe that the closures should 鈥渢arnish the whole MMC framework or indeed the MMC sector鈥. 

鈥淲e have successfully delivered very many high quality MMC schools with other contractors and will continue to do so,鈥 Watson said.

Danny Harris, regional director and head of schools and Colleges at Stride Treglown, the architect which designed Buckton Fields Primary School, told 好色先生TV that the practice was 鈥渟addened鈥 by the disruption caused.

鈥淥ur involvement centred around the architectural and design aspects of the projects rather than factory or site inspections.

鈥淲e鈥檙e deeply concerned that the schemes weren鈥檛 constructed as designed and we will work with the DfE towards a positive resolution if invited to do so,鈥 he said.

The government鈥檚 technical assessments of the schools were ordered after defects were discovered at two partially completed Caledonian Modular schools in Cornwall.

The surveys at the two schools, carried out after the firm鈥檚 collapse, are understood to have raised significant concerns. Both schools have since been demolished.

The DfE said it is working with its technical advisors on a strategy to either repair or replace the three completed schools and will share more information as soon as possible.

Caledonian Modular owner JRL Group has been contacted for comment.
