Type 4 Fire Risk Assessments - Devonshire Tower & Eglington Tower

Description

The appointed contractor shall be required to carry out a suitable and sufficient assessment of the fire resisting elements and compartmentation lines of specified multi-occupied residential buildings. Each intrusive survey and fire risk assessment of the fire resisting elements and compartmentation lines shall consider a number of factors, including the following: • The type of evacuation strategy adopted in the building, i.e. simultaneous, staged, phased or ‘stay put’. • The height of the building. • The vulnerability of occupants. • Fire protection measures within the building (e.g. compartmentation, automatic fire suppression, automatic fire detection). • Apparent quality of construction, or presence of building defects. • The combustibility of the building structure and the use of modern methods of construction, such as timber framing. • The number and location of escape routes. • The complexity of the building. Intrusive surveys and sampling will be required to provide suitable and sufficient information on: • The construction and condition of the fire resisting elements and compartmentation lines within the buildings. • The construction and condition of any interactions or connections of two or more fire resisting elements within the buildings, including inspection of service penetrations both above-ceiling, below-floor, or within risers. • The construction and condition of any current fire stopping within the buildings. • The construction and condition of any risers within the building, including those internally within flats. • The construction and condition of any cavity barrier located around window openings (located under window sills). • The construction and condition of any hidden voids, ceiling/floor voids, or inaccessible areas. The appointed contractor shall undertake a visual survey of each building in scope on appointment. The appointed contractor will undertake intrusive surveys within the common parts of each building and within the residential flats. The appointed contractor shall develop a suitable sampling strategy for each building which considers: • The extent of intrusive surveys recommended within the common parts of the buildings. • The extent and number of intrusive surveys recommended within the residential flats of each buildings. • Any requirements for specialist access equipment to fulfil the requirements of this scope. • Any requirements to seek independent, third-party test data on any materials used in the construction of the buildings • Areas where the integrity of fire resisting elements and compartmentation lines is critical but cannot be confirmed visually. This includes assessing: • Construction that separates individual flats from the escape route. • Compartmentation between individual flats. • Separation between common areas and other parts of the building. • The specific risks of the building, including: • The quality of existing information, such as building plans. • Signs of potential defects found during the previous type one fire risk assessment. • The age and construction type of the building. The appointed contractor will provide the Group with details of all the areas that are required for access within two weeks of appointment. The appointed contractor shall immediately notify the Group’s Client Representative of any significant defects or concerns it identifies during any intrusive surveys and sampling. Communication with the Client Representative will be via telephone and email and all significant defects or concerns must be reported within 48 hours.

The appointed contractor shall prepare a written report detailing the findings of each fire risk assessment of the fire resisting elements and compartmentation lines. The appointed contractor shall determine the exact format and content of their report, however each report shall include at least the following information: • An executive summary highlighting the key findings and recommendations. • An outline of their methodology for undertaking the assessment, including the rationale for the sampling strategy used including which flats were selected and what areas were opened up. • A clear outline of the significant findings of the assessment, written in plain English with appropriate definitions for any technical terminology. • A cross-sectional drawing, issued as a .dwg file, of the construction of the fire resisting elements and compartmentation lines. • An assessment of the fire risk associated with the construction, using a clearly defined methodology for assessing the likelihood and consequence(s) of fire. • A list of recommendations for remedial actions that the Group should consider taking to mitigate any risk associated with the construction of each buildings. The recommended remedial actions shall be ranked using a clearly defined priority scale. • Relevant photographs and other supporting evidence, this shall include floor plans showing the location of all areas sampled and location of any significant findings. • A statement of any assumptions and limitations that the Group must consider when interpreting the findings of the report.
