牛津城堡区b翼

The medieval castle and prison complex 牛津城堡区 offers a rich historical experience in Oxford. 它由牛津城堡组成, 建于11世纪, 豪华的Malmaison酒店, 以及现代住宅和商业开发的混合.

The B-Wing is known for its contemporary design, which stands out from the historical buildings. 这座住宅楼由33套公寓组成, spanning three levels in the north building and two upper levels in the south building, 顶层公寓提供复式生活.

南北两个街区的高度保持在18米以下, but the presence of combustible materials on all elevations required a full external wall assessment. 因此, our team evaluated the building's external wall construction to assess the extent of combustible elements and evaluate the risk these hazardous materials would pose to the life of its occupants.

To carry out a full Fire Risk Appraisal of External Walls (FRAEW), our team conducted a holistic assessment of the risk associated with external fire spread in the context of the use, 入住率, façade configuration and fire safety arrangements of the building. This helps provide a more pragmatic and risk-proportionate approach, and it categorizes the risk on a scale ranging from Low Risk to Medium Risk (Tolerable or Non-Tolerable) to High Risk. 记住这个框架, the investigation into B-Wing's external walls system (EWS) evolved over three comprehensive stages:

• Stage 1: Desktop Assessment: The first stage involved a meticulous examination of the external wall design. It was the initial step in understanding the potential risks posed by the wall construction.
• Stage 2: On-Site Intrusion: The second stage took the investigation to the actual site. Here, an intrusive examination of the external walls was carried out. This hands-on approach allowed for a more thorough understanding of the materials and their implications.
• Stage 3: Risk Appraisal: The third and final stage encompassed a holistic appraisal of risk factors. It extended beyond the walls themselves and included a visit to the communal and external surrounding areas. This comprehensive evaluation factored in façade configuration, 消防安全措施, 以及潜在的火灾隐患.

在调查的这些阶段, it became clear that the overall risk was deemed a medium risk, necessitating remediation work to reduce the items that were posing a risk.

编制了详细的修复工程清单, with the primary aim of transitioning from a Medium to a Low-Risk designation. 随后, our team was assigned to review the proposals from the contractor and closely monitor the works on-site. The objective was simple yet paramount – to reduce the risk to a level where the building could achieve an EWS1 B1 rating in the EWS1 form. 原则上, this signifies that the presence of combustible materials in the external wall no longer posed a significant fire risk, 进一步的补救措施是没有必要的.
