Project

Two Linac Rooms

Problem

• Limited Site Access
• Limited Building Space  

Solution

Ledite  Construction
Ledite allows construction of two rooms without disturbing existing structures. With fixed structures, in particular a pedestrian walkway, and limited space, San Carlos Hospital turned to Atomic and Ledite to build their new Linac bunkers. With the flexibility of a moveable block, Ledite allowed for egress into the construction area without the need to remove an existing walkway (which would have been necessary with concrete construction). With significant space savings compared to concrete, the standard maze entry Ledite rooms were able to be constructed within the confines of the existing courtyard, and did not rise above the existing second floor windows of the hospital. Significant time savings were achieved with the elimination of concrete deliveries, while the project was taken off the critical path.

Ledite Room construction:

• Easily fit inside existing courtyard
• Did not block second story windows
• Eliminated the need to tear down existing pedestrian walkway (the main artery for movement between buildings) for construction area access.

After calculating the amount of concrete that would have been required, as well as the problems associated with the site access and its limited area, the client decided on using Ledite block for bunker construction. Not only did it allow them to build the new bunkers where they had space, but it also eliminated any need to alter the existing buildings. The same could not have been said for concrete construction.

They could not be happier with the overall savings and speed of construction, as well as the trouble-free installation.

Problem

• Fast Track Schedule
• Cold Weather Installation

Solution

Ledite Construction
Ledite takes room construction off critical path, allowing convenient winter installation.

Faced with a fast track installation schedule, Fox Chase selected Ledite designed rooms in order to meet critical timelines.

With construction schedules dictating installation in cold winter weather, the facility was faced with serious challenges building with concrete in cold weather. The timetable did not allow for the long curing times needed with concrete which would have caused major delays with equipment and utility installation. Ledite was selected due to its ability to be installed at virtually any point in the construction timeline. By taking the room installation off the critical path the contractor was able to schedule the Ledite installation to meet their needs.

The cost of the Ledite installation was within 1% of the cost to build the rooms in concrete. But, ultimately the facility realized a savings of over $1,000,000. After seeing how the installation of concrete rooms would significantly disrupt their installation schedule, the client decided to use Ledite for their room construction.

By taking the rooms off the critical path and allowing installation when most
beneficial, the rooms were completed on time and at a cost virtually the same as concrete.

The client was pleased the deadlines were met and also relished the additional long term savings afforded by Ledite.

Two Linac Rooms

Problem

• Second Floor Space
• Limited Site Access

Solution

Ledite Construction
Ledite allows construction of two rooms on second floor with no service disruption.

Ledite modular block allowed for the construction of two linear accelerator suites on the second floor of the hospital. By eliminating the need for costly structural supports necessary with concrete, Ledite was easily installed within the second floor structure with no disruption to the occupied space below.

With site access located right off the main entrance, the ability to transport Ledite in and up to the worksite was a major logistical benefit. No structural changes were necessary for access. This saved approx. $100,000 as the hospitals main fibre optic communications lines did not have to be relocated.

An additional benefit of the modular Ledite was its ability to be temporarily removed to provide a door into the room to allow for equipment placement without transporting it through the hospital. This eliminated structural changes and rigging expenses, saving another $100,000. After the equipment was placed, the Ledite block was simply reinstalled and the rooms finished. A second floor location posed significant problems for traditional concrete room construction. By selecting a Ledite room design the client was able to build on the second floor without serious structural complications.

They were impressed with the ability to conveniently move block up to the site, and its ability to be temporarily removed and then reinstalled.

Not only did Ledite solve the problem of building on the second floor, but the client was especially pleased with the added savings of not having to perform work that would have been necessary with concrete.
