12 GeV Upgrade

Work continues on the few remaining areas of civil construction for the 12 GeV CEBAF Upgrade project.  On the accelerator tunnel air conditioning contract, Warwick Plumbing & Heating continues exterior work in preparation for the chillers to be delivered in May and the summer accelerator shutdown to commence.  The concrete slabs for the chillers are complete.  Electrical work to power the chillers is near complete.  The contractor started the exterior chilled water piping that will run from the chillers to the tunnel enclosure.

Records and Information Management Month Fact of the Week
In 1953, the cost for a gigabyte of storage was $2M.  Today, the cost is less than $1.  However, just because it's cheap to store all of our records on servers forever, doesn't mean we should do it.  In recent years, e-discovery has been on the rise.  Electronic discovery (or e-discovery) refers to searching, finding, and securing of electronic data with the intent of using it as evidence in a civil or criminal legal case.  Although relevant records are frozen and held from the destruction process in the event of legal proceedings, it is a best practice to observe and follow the lifespan of records in retention schedules.  Destroying records too soon is unwise and may result in legal sanctions, but keeping records beyond their mandatory retention periods also poses a liability to an organization in the event of lawsuits in which all records are required to be produced as evidence.  For more information about records retention, contact Kim Edwards at kindrew@jlab.org.
 

RIM Trivia Question of the Week
On the popular television series "Gotham," what is the name of the official record keeper of the Gotham City Police Department?  All responses must be received by Kim Edwards by noon on Friday, when a random drawing will take place of all correct answers. One person will win a Starbucks gift card! (Winners will be notified via email no later than 5 p.m. Friday following publication. Limit one gift card win per person.)

Last week's winner:  A random drawing was conducted and Carl Zorn won the Starbucks gift card.  The answer to last week's trivia:  Minority Report.

Facilities Management and Logistics

Lab-wide Cleanup Continues Through April 30
Jefferson Lab is conducting a lab-wide spring cleanup this week – through Thursday, April 30, in advance of a site visit on May 5 by members of the Commission to Review the Effectiveness of the National Energy Laboratories. The cleanup involves all divisions and all employees. All managers are responsible for ensuring the participation of their individual staffs. The goal is to clean up individual work areas, as well as to remove scrap wood, cardboard, metals, trash and any excess items that may have piled up over time both indoors and out. See memo for details: https://www.jlab.org/memo/lab-wide-cleanup-set-april-27-30

TED Building Entrance to Close Intermittently While Brickwork is Sealed
The Technology and Engineering Development Building main entrance will be closed intermittently for a couple more days as work is finished on cleaning and sealing the masonry brick walls at the exterior display case. To avoid over-spray on personnel, the TED Building entrance will be blocked during the work activities. Inside the TED Building, temporary signs will be placed for re-routing egress paths. Building Managers will be notified of exact dates. If you have any questions about this work, contact Rebecca Yasky at x7507 or Maynard Brown at x6162.

Beginning Week of May 4: CEBAF Center Parking Lot Will Be Impacted During Infrastructure Upgrade Project
A section of the CEBAF Center parking lot adjacent to the east side of the F Wing (facing Hadron Drive) will be fenced off for the contractor's lay down area throughout the Utilities Infrastructure Modernization (UIM) Computer Center Cooling and Power Upgrade project.  The contractor will delineate the area with fencing; 18 parking spaces will be impacted.

A temporary chiller and trailer will be staged inside the fence.  The upgrade work will take place in the CEBAF Center mechanical room and data center.  The work is scheduled to start the week of May 4 and continue until March 31, 2016.

Questions about this project may be directed to Michele Solaroli, Facilities Management, at x7751.

Environment, Safety, Health and Quality

MS4 at JLab
Many readers of this brief may not know what is meant by MS4. It is shorthand for Municipal Separate Storm Sewer Systems. This is our network of ditches, drains, ponds, etc. It doesn’t include the sanitary systems from restrooms.

The MS4 system is the means to control and direct the stormwater runoff generated from whatever does not soak into or infiltrate the ground and instead flows overland through natural and man-made conveyance systems (i.e., ditches, drains, ponds). These systems serve a vital function by helping to keep our drinking water and other water bodies clean. These systems help regulate the surges of water from major storms and help control soil and chemical run-offs into the rivers and bays.

Major factors that work in concert to help protect the Hampton Roads environment include: types of land use, amount and frequency of precipitation, natural versus constructed drainage systems and stormwater control measures. JLab is doing its part and you can help too by reporting anything that doesn't belong in our ditches. Call ext. 7308 for more information or to report concerns.
