The Building:

At the spaces for the cyclotron and gantries, the walls were prepared, painted and the base coat of the epoxy floor was installed. The removable roofs were also constructed and set in this space. When the equipment is delivered, the roofs will be opened so the equipment can be lowered into the space (see photos of this process at the Scripps Proton Therapy Center in San Diego, CA). At the fixed beam rooms, walls were prepared and painted. Installation of the cooling towers and piping to service the spaces was done throughout the month. All this prep work paves the way for the future equipment arrival.

On the first floor, the main electrical room gear was installed and connected to be ready for power in May. Installation of the Varian and VIP/Ambulance elevators also began. On the second floor, overhead ductwork, plumbing and fire protection piping were completed. Design work began on the treatment corridor and recovery space. On the third floor, priority walls, overhead ductwork, plumbing, medical gas and fire protection were completed.

On the exterior of the building, the windows on the ground floor were installed. Roof detailing and flashing occurred as well as installation of the metal panel system at the curtainwall area and trellis began.

The Site:

During the month of February site crews began replacing the permanent roadway removed earlier during construction. The installation of permanent gas and electrical service continued through the month.

The Building: Concrete Structure:

In the concrete structure, mechanical and electrical the team continues installing cable tray, conduit and piping. At the cyclotron, the team placed topping slabs to make up the rest of the roof shielding thickness. Walls at the third level perimeter and interior walls of the cyclotron electrical room and related rooms were placed. Also, shoring throughout the cyclotron area was removed and concrete rub and patch will occur followed by painting.

At the gantries, the team formed and placed the filler slabs which make up the shielding thickness at the labyrinth and beam transport system areas. The bearing wall which supports the balance of the third floor structural steel was placed. Concurrently, the walls which make up the last layer of the Gantry 1 through 4 walls were placed.

At the fixed beam, formwork and rough in was completed at the roof slab. It was followed by placement of topping slabs which make up the balance of the shielding thickness. The shear walls which make up the northeast corner of the structural steel building continued to be placed throughout February allowing the balance of precast to be erected in mid-March.

The Building: Steel Structure:

Steel crews continue decking the third floor and roof over the retail spaces as well as the trellis steel on the southwest corner of the building. They will also erect and deck the third floor steel over the concrete bunker where various staff offices and toilets will be. Metal stud framing, plumbing and mechanical system piping, as well as electrical conduits, were installed on the first and second floors.The glazer continued building of the curtain wall system at the southwest façade of the building. Drywall crews worked with the glazer to frame the exterior column wraps that interface with the curtain wall. Windows on the north and west elevations were installed in precast.

On the interior, drywall crews continued framing priority walls at the south end of level 1 and throughout level 2 and will begin to frame/hang stair and elevator shaft walls. The mechanical and plumbing teams continued hanging overhead pipe, duct work on level one and begin hanging on level two.
