LCLS Construction Begins, SLAC Closures Listed
Since 2000 and before, SLAC has been gearing up for the Linac Coherent Light Source (LCLS). Now, after years of preparation and planning, the time for construction has finally arrived. Employees should keep an eye out for a number of accessibility and traffic changes around SLAC.
SLAC crews have finished a number of preparatory construction projects in the last few months, such as the removal of the FFTB and demolition of the high bay and other structures to clear the way for LCLS construction. Now that the research yard and other areas have been cleared, Turner Construction Company will take over managing the 28 month LCLS construction project, which is scheduled for completion in 2008.
"We appreciate everyone’s help in this process," said Tom Malloy, senior project manager for Turner Construction. "We're very excited about helping forward the science that everyone at SLAC is involved with."
Specific changes and closures that will impact SLAC employees are listed below.
The official hand-off to Turner occurs on Sept. 11, with the closure of the Alpine Gate entrance to regular traffic. SLAC employees will not be allowed to use this gate during LCLS construction. All construction workers and related vehicles will use the Alpine Gate entrance exclusively between the hours of 6 am and 6 pm. Please note, after 6 pm a minimal amount of construction traffic (20–30 cars a night) will be routed through the main gate.
PEP Ring Road will be bisected and closed to through-traffic at two points: just past the Collider Hall from the north, and at the intersection of Alpine Gate Road from the south. The area in between will be a restricted area maintained by Turner for construction activities.
On October 1, Turner will erect a fence bisecting the research yard. The north and south sections of the research yard will be accessible separately.
Gate 17 will be open 24 hours, seven days a week, allowing access the north side of the research yard and interaction region 2 (IR2).
Gate 30 will remain open 24 hours a day, 7 days a week, allowing access to the south section of the research yard and interaction region 4 (IR4).
The antenna tower / overlook road will remain open exclusively for emergency vehicles to access both sides of the research yard.
Turner Construction Company will be responsible for controlling access to the restricted construction areas during the LCLS construction period.
