PART 3 - EXECUTION

3.1 Use of Owner-furnished Stations, programming code and Stanford Standard graphics.

A. To ensure consistency of programming, consistency of database structure, and consistency of “Look and Feel” of User Interface, Stanford University FESO provides Niagara 4 template stations for new or AX-upgraded Niagara installations. These station templates are named BuildingWS.ntpl and BuildingJace.ntpl for new N4 projects and for projects that migrate existing AX sites to N4. Each include several preconfigured components key to a successful implementation of Stanford N4 Standards, namely; a Stanford Kerberos Authentication Scheme, Stanford Categories, Stanford Standard Prototypes and Roles, and a Stanford Tag Dictionary. Preconfigured objects also include Data Modeling examples in the form of Hierarchies typically used for a Stanford site, sample graphics for common equipment types, and a sample navigation scheme with core site pages, Alarm Classes, and representative alarm messages with correct Bformatting; one Modbus JACE station with representative Modbus points configured, and representative gfx code for each type of Distech controller.

B. The term “representative’ shall mean it is understood that the Stations, graphics and gfx code are copied from a project that is very close to, but may not exactly match, the requirements of this project. Upon receipt of Stations, graphics and gfx code, Contractor shall have 30 business days to thoroughly review and study the furnished Stations, graphics, Niagara wiresheets and gfx code, and to list, in writing, any reason why the furnished material cannot be adapted to this project. For each reason, Contractor shall include a proposed solution that is consistent with Stanford Standards and will not adversely impact the project schedule. Owner shall be the final judge of acceptance of proposed alternative programming solutions.



C. After 10 business days to thoroughly review and study the furnished Stations, graphics, wiresheets and gfx code, Contractor shall inherit full responsibility for the functionality and performance of the furnished Stations, graphics, wiresheets and gfx code.

D. Contractor is completely responsible for successfully passing all Functional Performance Testing (FPT) prior to project close out. The fact that Contractor is using a code template that was furnished to them, or the fact that code passed FPT at the beginning of the project, will not be considered acceptable reasons for failure to pass any commissioning FPT at project close out.

3.2 Compliance to Owner’s Computing and Security policies.

A. The Contractor shall at all times fully comply with all Stanford University Computer Policies.

B. Be forewarned that Stanford University Computer Policies are constantly evolving and may change to be increasingly restrictive during the execution of this contract.

C. Owner does not guarantee that Contractor will have remote (off-campus) access to the controls system.

D. Violation of Stanford University Computer Policies may result in revocation of User access to the Stanford University Computer Network and/or computing equipment physically removed from the Stanford University Computer Network.

E. Examples of controls system security policies include:1. Minimum password length.2. User access credentials cannot be shared. Each user accessing system must have unique

credentials. 3. User credentials may not be transmitted by email or text message. User credentials inside a

permitted.5. Contractor passwords shall be unique to Stanford site – passwords used at any other site are

not acceptable. Ubiquitous “Branch” passwords are not acceptable.6. Contractor to apply all software updates and security patches immediately (within 72 hours) as

they become available.7. Owner shall, at all times, have at least 1 Windows Operating System administrator account on

all servers, Niagara Super User Station accounts for all JACEs and Supervisor Stations, all Niagara Pass Phrases and credentials for access to all Platforms.

8. Any and all required IDs and passwords, including hardware locks for access to any component or software program shall be immediately provided to the Owner upon request, at no additional cost to Owner.
