What to look for in terms of construction, traffic, and noise:

  • Del Rey and Glorietta school campuses will be closed to the public all summer.
  • Entry for construction vehicles and equipment will be from Glorietta Blvd. at Glorietta Elementary.
  • Heavy equipment will be moving onto the job sites beginning June 12th.
  • The week of June 12th will be noisiest due to the demolition work of the old portables.
  • Excavation for the building foundations, conduit, and underground boring will be going on through the end of July.
  • The modular units will be trucked through the streets on the dates shown in the schedule, around July 26th.
  • Asphalt paving and slurry coating will be done largely in July.
  • NOTE: The City of Orinda will be paving Martha Road, likely in mid-June, after school closes.

American Modular Systems, Inc. (AMS), manufacturer of the Gen7 21st Century modular classroom building, will complete factory production and installation of the buildings on their newly constructed concrete foundation walls before the start of school on August 22, 2017.

Electrical, plumbing, data, and fire alarm subcontractors will hook-up to the building after it is placed.

In the week prior to the start of school, teachers will be able to set up their classrooms. Minor "punch list" may also be done this week, if needed.
