As mentioned above, accessing many of the rooms on site can be one of the biggest challenges. It means ensuring our 4-week plans are constant and up to date, to allow for access documents to be submitted early before works can take place. Any underground project poses its own challenges, particularly as contacting one another on site becomes an issue when mobile phones are just not an option. To overcome issues of communication, we use two-way radios.
Finally, the biggest challenge of all has been the installation surrounding fire stopping compartmentation. Because the original contractors who performed the fire stopping installation did a poor job, lintels have been retrofitted, by necessity, through the majority of walls. This means we have had to adapt our installation routes to suit, setting before and after most wall-lines.
