Project Name: 911 Electrical

Agenda & Notes

1. Introductions

2. Background/Purpose

· Replace all Medium-Voltage switchgear

i. Includes coordination with PPL for any/all utility requirements; PPL requirements shall be included in base contract award

· Replace all Main Distribution Panels, Unit Substations and Switchboards

· Replace all Motor Control Centers (MCC)

· Replace Emergency Generator System (including day tank & Automatic Transfer Switch (ATS)) In order to increase the functionality & connectivity of the emergency generator system, Contractor shall:

i. Design & construct an upgraded, code compliant emergency power system

ii. System shall include a main distribution switchboard, with (3) properly sized breakers (plus 1-spare section for future) to connect to (3) new/additional properly sized ATSs

1. 1 ATS shall feed Life Safety System (NEC Art 700) loads

2. 1 ATS shall feed Legally Required Emergency (NEC Art 701) loads

3. 1 ATS shall feed Optional Standby Systems (NEC Art 702) loads

4. Each ATS shall be 4P (switched neutral) and shall include maintenance bypass option

5. Connect each ATS to an associated/dedicated distribution panelboard, properly sized and complete with breakers, to distribute the Contractor-separated NEC loads properly throughout the facility

6. Interface ATSs with the elevator controls to ensure they are coordinated with the facility’s new regenerative drives

iii. To facilitate rewiring and reconnecting the system loads to the appropriate ATS and associated distribution panelboard, provide (8) additional emergency panels, to be located in the Center Core electrical closets. Four (4) shall be 480V, 3-phase; four (4) shall be 120/208V, 3-phase; all complete with breakers. In addition, provide (4) additional 15kVA, 480-120/208V, 3-phase dry-type transformers.

iv. Provide properly sized load bank for system testing (per PBS P-100)

v. For purposes of initial estimating and bidding, Contractor shall assume that a 500kW, 480/277V generator (which is an increase over the 250kW indicated in the 2013 PDS) along with a 250kW fixed load bank shall be required, and that all downstream equipment and devices shall be sized accordingly. Contractor shall size the actual generator per calculated loads during Design phase. The 500kW generator size is a current/common estimated size based on existing generator (circa 1978) rating, increased building loads (including future/planned HVAC freeze protection requirements, increased tenant/occupant requirements, etc.) and to provide reasonable future load/growth.

· Replace all Lighting and Power Distribution Panelboards

· Replace/Upgrade Office Tower Distribution System

i. Office Tower has (3) sets of stacked electrical closets – “East”, “West” and “Center Core”

ii. East Closet – Provide (2) 800A bus duct risers, entire tower height

1. Provide (2) 175A/3P Plug-In Breakers, (1) normal & (1) isolated ground/computer power, each closet

iii. West Closet – Provide (2) 800A bus duct risers, entire tower height

1. Provide (2) 175A/3P Plug-in Breakers, (1) normal & (1) isolated ground/computer power, each closet

iv. Center Core Closet – Provide (1) 1200A bus duct riser, entire tower height

1. Provide (1) 200A/3P Plug-in Breaker for bus tap, each closet

· Upgrades/repairs to all East & West Electrical Closets (2 closets per tower floors 2-8)

i. Install 1-hr fire rated doors (2-doors required per closet)

ii. Install 1-hr rated separation (wall) between power and adjacent data/LV sections

iii. Extend access floor to panels in electrical power closet side of closets, to facilitate standing room over/directly in front of panels/equipment.

iv. Install fire stopping under access floor at entry to electrical power closets to establish 1-hr rating/separation from tenant occupied space

· Repair/upgrade Electrical Grounding System

i. Install copper grounding pads in each Center Core electrical closet, basement switchgear rooms, and the mechanical spaces (basement, sub-basement & penthouse)

ii. Bond all grounding pads together using properly sized copper cable

iii. Bond all grounding pads to building ground in the switchgear room (incoming service lateral space)

· Contractor shall field verify all loads and provide updated panel schedules and labeling for all equipment

i. Includes a requirement for the proper ganging of all multi-wire branch circuits to be operated by common 3P circuit breakers per NEC

· Install new sub-metering (including connection to the Building Automation System; PC workstation to be provided by GSA) at the following facility locations:

i. Lighting Panelboards

ii. Power Distribution (Plug load/Receptacle) Panelboards

iii. MCCs (at MCC Level Only; don’t need to sub-meter each bucket)

iv. Elevator Panels

v. Major Equipment

· Provide Electrical System Model, including arc flash system study, post-construction, with proper arc flash hazard labeling (calculated incident energy, PPE required, etc.) on all new equipment

· All penetrations shall be fire stopped

· Provide rubber matting in all electrical rooms (including electrical closets), to include mat markings indicating appropriate/proper NEC clearance/floor space requirements

· Provision for any/all temporary construction, infrastructure, power equipment, etc. necessary to maintain full building operation (including electrical system and other non-electrical systems, e.g. mechanical/HVAC, telecommunications, fire detection & alarm systems, mass notification, etc.).

· Enhanced Commissioning, including thermal imaging

In addition to the base bid items/scope described above, the project also includes the following additive bid item:

· Design & construct a Lightning Protection System (LPS) for the facility

· System shall comply with NFPA 780 and all other applicable Codes and Standards

· LPS down conductors shall be installed internal to the facility; exterior (on building façade) down conductors are not acceptable
