Addendum to the M. Stephens Rehab and Addition

1.0 Background

1. This project will be completed as a partnership with the Valley Forge Park Alliance. Proposals for this project shall include all Base bid items as well as Options A through D. Option E will not be bid as a part of this project and will be solicited and awarded separately by the Valley Forge Park Alliance. This addendum document will serve to provide the separation between the two additional options this will create. Options D will include only the foundations, underground utilities, sitework, and stonework for the new addition and deck. Option E will include the construction of the new addition and deck above the foundation walls completed in Option D.

2.0 Scope

1. Option D shall include all footings, foundations, drainage, stonework for the foundation walls, and routing of all utilities to the new addition.

2. Option E shall include the deck framing, decking and handrails, and construction of the new addition on top of the Option D foundations. Construction of the new addition includes all finishes, utilities and fit out as shown in the project documents.

3.0 Objectives

1. The objective of this addendum is to separate out options D and E from the base bid for bidding purposes.
