Work Sequence

There are no construction phases shown. The Contractor must keep the access between the playground and school open. The kiss and ride must remain open during school arrival and dismissal times. A major school entrance #2 must be maintained.

The project perimeter, storage and laydown areas must be maintained with 6 foot chain link fencing.

Parking is extremely tight.

The school has requested that one basketball hoop remains accessible during the

construction. The South West corner has been chosen for this and will not be included

in the staging area limits.

There is a 2hr fire wall crossing the modular. Any penetrations through this barrier must

be in accordance with specification section 07910 Through Penetration Protection

Systems.

Since playground access must be maintained during construction, extra attention needs

to be given where this path intersects with the construction entrance. The construction

entrance can be opened for access but must remain closed while not in use to avoid

intersecting the students’ path to the playground.

All contract revision, prior to bid, shall be made by addenda ONLY.

All bid related questions shall be made in writing to Subhash Gambhir

([email protected]) or by fax at 571-423-2237; or to the Senior Buyer at fax number

Deadline for Contractor questions is Friday, November 16 @ 4:00 p.m. Any questions

after the 16th may or may not be responded to. Only contract changes will be issued in

an addendum.
