Immediate Space Challenges
•Collections Yard (0.8 ac) and staff support facilities
•Displaced staff from P1 Headworks project (28 staff)
•Impacts of OCTA Front Entrance Modifications
•Admin Building parking (loss of 70 spaces)
•Wastehauler location (unresolved)
•Construction staging areas (especially Plant 2)
•Aging Plant 1 trailer complexes
•Engineering Trailers A, B, E, and F (111 staff)
•Risk Management (11 staff)
Long Term P1 Space Issues
•Headworks replacement
•Primary clarifier replacements
•Activated Sludge Plant 1 replacement
•Advanced treatment facilities for future regulations
Conclusions
•Space limits impacts
•Multiple facilities involved
•Interim provisions
•Require long construction sequences
•Major expenditures
•Property acquisition costs could be offset by
significantly reduced project costs
•Contractor costs for off-site staging
•Interim facilities
•Premature demolition to open required process areas
