Today, more tall buildings are being planned and constructed Greater focus than ever before, with 438 towers – defined as those with needs to be more than 20 floors – proposed, in planning, approved, or under construction in London, according to the 2018 placed on survey by New London Architecture1. mitigating the As the number of tall buildings under construction in the UK increases, greater focus associated risks, needs to be placed on mitigating the associated risks, which can lead to project delays which can lead and significant reinstatement costs. to project delays While the forthcoming Brexit changes and uncertainty around building regulations could impact planned projects moving forward, we expect to see this trend continue and significant over the long-term. reinstatement This paper has been designed to highlight and bring greater awareness to the various costs. risks and insurance challenges associated with tall tower construction in the UK. Marsh • 1 London’s Tallest Buildings, Completed and Planned The graphic below (FIGURE 1) shows a selection of the tallest completed, under construction, and proposed buildings in London. Out of these buildings, 13 are proposed or under construction demonstrating how London’s skyline is set to be transformed over the next decade and the growing trend towards tall tower construction. The height of London’s skyline remained largely unchanged during the 1980s and 1990s, with only Tower 42, One Canada Square, and the Panoramic being completed at a height of more than 20 floors. In contrast, since 2000, 110 buildings with more than 20 floors have been built in London, with a further 52 under construction and due for completion over the next three years. The Shard is currently London’s tallest building standing at around 306 metres, followed by One Canada Square and 110 Bishopsgate. 22 Bishopsgate, which is currently under construction, will surpass all but the Shard when completed.

This year’s pipeline has seen an increase of 260 tall buildings compared to 2014, bringing the current number of those proposed, approved, and under construction to 510, according to New London Architecture (NLA)2 (see FIGURE 3). The NLA analysis also suggests that living in tall buildings is becoming increasingly accepted as a key part of our housing mix. Over 90% (458) of the tall buildings coming forward are residential and have the potential to deliver 106,000 new homes. Meanwhile, Mayor of London Sadiq Khan claimed, “our housing crisis is the biggest threat to London’s future,” in the London Housing Strategy 20183, which sets out to remove some of the existing constraints on resolving this issue2. 4 • Sky-high Risk: The Impact of Increasing Tall Tower Construction in the UK It is not just FIGURE Comparison of London Tall Buildings Pipeline 3 2016-2018 the number of SOURCE: NEW LONDON ARCHITECTURE, marsh.com/insights. these projects 500 that needs to be taken into 400 consideration, but also the fact 300 that the height 200 of the individual buildings seems 100 to be rising. 0 2014 2015 2016 Proposed (pre- and post-formal submission) Refused (since last review) Approved Under construction Completed Status unknown A number of tall building projects are also For example, out of the top five tallest underway in other metropolitan areas towers in London, two were built in the across the UK.

Marsh • 5 Heightened Risk Mitigation The increasing number of tall towers has given rise to certain perils before, during, and after construction. There are several risk and insurance challenges that developers and contractors need to consider and potentially transfer via insurance to remove unnecessary risk from the balance sheet. Post-construction, tall towers have proved to be targets for Fire and/or Escape of Water attacks in the past, such as the World Trade Center buildings The possibility of fire and/or the escape of water represents on 11 September 2001. significant risk to a project’s practical completion date. Either one of these events has the potential to cause severe damage The safety of workers is also of paramount importance. to the works and significant delays. This risk is multiplied in Contractors will likely have a large number of workers on site at a tall tower, due to the high concentration of value in a single any one time and need to think carefully about adequate safety structure. measures and what to do in response to terrorist threats. • Escape of water: Especially during the installation and testing phase of bathrooms, washrooms, and sprinkler systems, this can cause substantial claims if leaks go undetected, as water damage can impact several floors of the building and has the potential to damage equipment, such as generators and cables located in basements. The Construction Insurance Risk Engineers Group (CIREG), in conjunction with the UK Construction All Risks Underwriters Group, has produced a best practice guide that can provide valuable insight for avoiding water damage claims. • Fire: The Joint Code of Practice (JCOP) needs to be adopted and complied with for tall building construction. JCOP was first published in 1992 in response to two significant fires that resulted in a combined loss in excess of GBP150 million – a level where insurers were questioning whether the provision of insurance for construction sites could continue economically.
