[X-end]
  * Started the replacement of cables from 15th.
  * Dismounted the pre-isolator.
  * Removed the cables above the F1.
  * Removed some screws from the inside of F1.

[ITM]
  * The items from Akeno and Mitaka were delivered on 14th.
  * Transported the bridge frame from the X-end to the center area on 14th.
  * Lifting up the items to the 2nd floor by MESCO on 17th.

  * X-end: Reassembly of the EQ stop and the cabling from 20th.

 * Top rid of PR2 and PR3 vacuum tank were fixed
  * Note that the feedthrough flanges are not closed yet.
  * During the fixing, we accidentally moved the injection beam of the Oplev. Alignment was lost.
  * We need to re-align the main beam. So far, we are planning to do it in the week of the commissioning WS.
 * PR mirror position was measured by FARO.
  * The position of the mirror is off from the design by:
   * PR2: (-9.4, +0.5, -6.4)
   * PR3: (-3.5, -0.5, -4.9)
   * PRM: (+4.7, 4.6, -1.5) Note: PRM is fixed
     Note that these values are relative to the side flange of the vacuum tank at the HR side. x is the norm of the flange surface, and z is the norm of optical bench.
