About this file

Written by GovTribe AI · Jan 22, 2025

This is a Questions and Answers document for a lightning protection system project at Building 1, accompanied by technical specifications for surge protective devices and electrical plans. The Q&A addresses specific technical requirements including the absence of an existing counterpoise ring, location of surge protection devices, bonding requirements for water services, and specifications for lightning arrestors on telephone, radio and TV antenna services.

Key technical details include the need for approximately 700 feet of 3/0 copper and conduit in the basement for bonding three water services, installation of surge protection devices on two Siemens 208/120 2500A electrical service panels, and telephone service connections in room B108A. The accompanying specification section 26 43 13 details requirements for Type 2 Surge Protective Devices, while electrical plans 01EA-EP101 and 01WA-EP101 show equipment locations and demolition details. The project requires bid bonds per FAR 52.228-1(b), and allows high-compression crimps as an alternative to exothermic welds for underground grounding connections.

631-25-001 Building 1 Lightning Protection

Questions and Answers

1. Does Building 1 have an existing counterpoise ring? If not, will one need to be installed for this project or will ground rods at each downlead suffice?

Answer: There is no existing ground ring for the building and no new one is proposed, downleads should suffice. Final drawings shall be provided after field verification by the lightning system designer.

2. Note 4 on drawing 01-EP112 mentions a one line diagram showing where surge protection devices are to be installed. Can this drawing and specs for the surge protection devices needed be provided?

Answer: Drawing 01EA-EP101 and 01WA-EP101 added for reference. Only SPD is required from these two drawings. Spec section 26 43 13 added.

3. Note 13 on drawing ESS503 calls for bonding to domestic and fire waterlines, can a drawing showing the location and quantity of lines needing bonded be provided?Answer:

PDF added for reference. Water services will need bonded. This needs to be field verified and add. Approximately 700’ of 3/0 copper and conduit will be needed in the basement.

This includes bonding the 3 services together.

4. Note 14 on drawing Ess503 calls for lightning arrestors on the telephone service, radio and TV antennas, can a drawing be provided showing the location of these items?

Answer: Telephone service is in room B108A and the radio antenna is located on the flat roof in the center of the building.

5. Are bid bonds required with quotes.

Answer: Per FAR 52.228-1(b), the bidder shall furnish a bid guarantee in the form of a firm commitment, e.g., bid bond supported by good and sufficient surety or sureties acceptable to the Government, postal money order, certified check, cashier’s check, irrevocable letter of credit, or, under Treasury Department regulations, certain bonds or notes of the United States.

6. Will surge protection devices be required for the communication and low voltage lines entering the building? If yes, please confirm the type of system, maximum operating voltage and amperage, number and size of wires, method of connection, data speed, and length of run.

Answer: Yes, Phone service is in room B108A

7. Please provide the quantity of main electrical service panels requiring surge protection.

Answer: 2

8. Please provide the manufacturer of the electrical service panel, and the voltage configuration.

Answer: Siemens 208/120 2500A

9. Will high-compression crimps, listed for the purpose of underground grounding connections be permitted as an alternative to exothermic welds?

Answer: Yes

10. Will services need to be bonded?

Answer: Yes, building 1 has 3 services and they will need to be bonded together with a 3/0 copper. The 700’ in question 3 includes the water and electric services.
