Project
Following a series of leaks, we have been asked to provide a cost for replacing the LTHW pipework that serves the CSSD plantroom and a DHWS Calorifier.
The existing heavy steel pipework had reached the end of its operational life, necessitating a transition to stainless steel pipework. This replacement had to be executed while ensuring continuous heating to the air handling units and domestic hot water, with the operation constrained to a single 24-hour downtime window.
The Solution
We undertook the replacement of the existing steel trench pipework, which ran from the plant room to Theatre 3. Works began with the establishment of a safe working area, including the removal of existing flags and cross-member beams within the trench to allow for the installation of new bracketry and stainless steel pipework.
The new pipework was routed through the trench, along the roof and down to the Theatre 3 AHU and external connection points feeding the heater batteries. A new BigFoot system was installed over the Theatre 3 roof to support the pipework infrastructure.
To minimise service disruption, the paperwork swap was completed over a weekend. All new pipework was insulated using Rockwool insulation with a PIB finish, and standalone trace heating was installed to maintain temperature control across the service.
Redundant pipework was stripped out and disposed of appropriately. The new pipework was then balanced, dosed and re-energised. On completion, the flags were reinstalled to their original location.
The Benefits
The replacement of the aged pipework will reduce, if not completely eliminate, future leaks, ensuring consistent heating performance and uninterrupted theater operations.
Benefits
Due to the fast response and the multi-skilled team available, we were able to assist the facility in gaining a heating solution in a very short turnaround time.
This fast response ensured the facility could remain open and avoid closing —preventing huge losses.
