7. Beamline Construction (Rev. July 21, 1998)
After the beamline Final Design Report has been reviewed and approved, the CAT can begin the installation of the beamline components on the experiment hall floor. The typical sequence of beamline installation is:
- experiment stations constructed,
- PSS and utilities installed,
- PSS and shielding validated, and
- beamline components installed.
Because access to the stations is needed to verify the integrity of the station shielding, in general, beamline components should be installed after the shielding has been verified or arrangements have been made with the beamline commissioning team.
Prior APS approval is required for all installations and modifications of permanent structures in the APS experiment hall and LOMs. If the facility design has not been explicitly approved via the beamline design review process described above in parts 3 and 4 and in the beamline design report guidelines in Section II, then the CAT shall submit its designs, including a written programmatic justification to the User Technical Interface Group Leader, who will coordinate the design review and approval.
For the installation of beamline and LOM facilities, the APS will make licensed and qualified electricians, pipe fitters, carpenters, and other "skilled trade" workers available to APS users for those beamline construction and installation tasks (hutch installation, electrical distribution, pipe fitting, etc.) that require these types of workers, and for any other tasks that users wish to have done by such workers. User institutions may not contract directly with contractors for any construction work on the APS site. (Refer to the User Policies and Procedures for Use of Third-Party Contractors at the APS for details.) Examples of construction work include:
- Changes to the physical plant, including any drilling into floors, walls or ceilings, or altering of any permanent structure.
- Use of industrial lifts, scaffolds or cranes.
- "Hard-wire" installation or tie-in to facility utilities, including electrical, plumbing, ventilation, or water systems.
Contact an APS Floor Coordinator to arrange for on-site time and materials construction support.
It is recommended that, early in the utility design process, the CAT designers contact an APS Floor Coordinator to arrange for a review of the conceptual layouts and installation plans. The APS engineering support will work with the CATs to address facility tie-ins, available utility options, and contractor services.
The CAT is responsible for keeping current beamline and facility drawings on file with the APS. Drawings should be kept updated to reflect as-built conditions and, as facilities change, should be submitted as design report updates.
