Break Down of Increments

•Increment 1: Foundation Only Package

•Increment 2: Architectural & MEP

•Increment 3: Exterior Curtain Wall Systems

•Increment 4: MEP & Medical Equipment Anchorage

•Increment 5: MEP Pipe, Duct & Conduit Bracing

•Increment 6: Major Structure Except Foundation

Scope of Increments 1 & 6

• Increment 1 originally contained the entire major structure including foundation and was divided into 5 segments

• The foundation was separated into it’s own increment, at owner’s request & became Increment 1

• Increments 2 - 5 were already designated & input into Logbook, OSHPD’s project tracking system

• Increment 6 added and includes the balance of the major structural system

The design team has requested the package be submitted and permitted on a floor by floor basis. This request is currently under review.

Phased Review - Lessons Learned

• Continual communication between OSHPD, contract reviewers and designers is essential in segmented review

• Coordination between disciplines on the design team is essential– Continuously updating team on changes in the design

• Submit long lead reviews, i.e. geotech reports, design criteria, AMC, material testing reports, etc., far in advance of plan review submittals

More Lessons Learned

• Deciding what to put into each increment is key – Including “unique” items may shift focus from major

portions of the work

• Use every tool in the box– Reminders and checklists– Review FAQs, PINs & CANs

• Flexibility by all parties is essential in resolving schedule conflicts and design changes
