PROJECT EXECUTION

1. General:

a. The general arrangement shall follow the layout shown on the created drawings as closely as practical. The reason for deviation from the design shown on the drawings shall be submitted to the Project Manager for evaluation before manufacture. The installation shall

B - 6 be neat and workmanlike.

2. Assemble:

a. Panel stiffeners shall be used to restore the stiffness to its original uncut rigidity where multiple equipment cutouts have reduced it.

b. All switchboard panels shall be electrically grounded individually, with provisions provided to bond each section solidly to the next and allow for connection with a #4 Copper to the outside Ground.

c. Others shall perform any required field assembly of the switchboard panels. The switchboard panels shall be structurally secured to the floor and set plumb and level.

d. During Transportation and Delivery, precautions shall be taken to ensure that Switchboards are covered and/or protected from any transportation hazards. Upon Delivery, Scratches or damage shall be restored to the original specified condition.

3. Shipping:

a. For transportation, each panel assembly shall be palletized on a 42” square minimum sized

Pallet (not to exceed 48”). The Pallet shall be made of material that supports the weight and stresses involved in shipping the panels in the upright position. Panels shall be bolted to the pallet, and additional support shall be added to keep the pallets upright during shipping.

A suitable substitution may be used, provided the Project Manager approves it.

b. The panel assemblies shall be covered with a 2-mil opaque plastic bag and then wrapped with shipping plastic wrap. Adequate foam and wooden protection shall be placed over the front-side components to protect them from hazards during shipping. A suitable substitution may be used if approved by the Ocala Engineer.

4. Testing:

a. Factory Test – Each switchboard or control panel shall be completely fabricated, assembled, and wire-checked against AC and DC schematics that the winning bidder will engineer.

Testing shall include, but is not limited to:

i. Point-to-point wire continuity testing.

ii. Current and voltage input testing for each input.

iii. Insure proper current trace from each shorting block through each relay and its return path.

iv. General control testing of manual controls, shorting test switches, and trip disconnects.

Failure by the City of Ocala to return shop drawings within fifteen (15) days due to actions or omissions on the part of the Contractor shall not constitute grounds for an extension of the proposed delivery time.

b. A maximum of two reviews for each submittal will be allowed to establish conformance with the specification. In the event an item has been determined by the City of Ocala not to be in conformance with the contract requirements after two reviews, the Contractor shall pay the City of Ocala an amount equal to the cost incurred by the City to perform additional submittal reviews required to establish conformance with the specification. These costs will be deducted from the Contractor's retainage before final payment.
