1 OVERVIEW

The task is supporting the Independence National Historic Park The park operates multiple buildings including Independence Hall, the Liberty Bell complex and various offices thru a Central Chilled Water Loop installed in 1998. The loop is supplied from a chiller plant located at 3rd and Dock Streets in Philadelphia and is distributed through an insulated, buried carbon steel pipe network consisting of supply and return lines with a maximum diameter of 8”. The park is interested in determining the current condition of the pipe interior and remaining wall thickness in order to estimate remaining service life.

2.2 Assumptions and Constraints

This section defines the assumptions and constraints underlying this contract, which the Contractor has considered in developing their technical solution. The Contractor shall address the following Constraints at a minimum as well as their own assumptions and constraints. Note that Section 5, Security Requirements, below, covers specific regulatory security aspects.

This section lists laws, rules, regulations, standards, technology limitations and other constraints that the service and/or service provider must adhere to or work under.

2.2.1 Access Control

User will have access to piping from valves located within the chiller plant. It is assumed that all reading will be taken using device(s) inserted into the pipeline. Pipeline is buried. Manholes are considered confined space, permit required. Entry is assumed to not be required. If access to manholes is required, contractor should identify and detail access requirements in their proposal. Contractor personnel requiring entry into confined space will be required to document OSHA confined space entry certification.

2.2.2 Conditions

Piping is assumed to be installed per provided drawing (Attachment #1). Chilled water system is assumed to be filled with water, with no pumps running during the actual inspection. Contractor should indicate any special requirements in their proposal.

Time limit for shutdown of pumps is 72 Hours.

Excavation of any portion of the piping would require archaeological monitoring and tribal monitoring and is therefore to be avoided.

2.2.3 Data

All data (e-mail traffic, contact information, calendar contents, etc) is and shall remain the property of the government. The Contractor shall ensure that the government retains access and download capability of all data for research, investigation, transfer, or migration to other systems.

In addition to the provided drawing (attachment #1) some sectional drawings of the pipeline are available on request. If any additional drawings are required/desired during the proposal stage, contractor shall provide a written Request for Information (RFI).

2.2.4 Performance limitations.

This scope will be performed outside peak cooling season, between November 1st and April 1st. It is assumed that the system will not be required to be shutdown in excess of 72 hours at any one time without returning the system to normal operation and operated for a period of at least 24 hours. This system supports critical IT & security infrastructure year-round and provides critical climate protection to historic structures and objects including Independence Hall and the Liberty Bell.
