SI RFI # QUESTION RESPONSE

1 “A. Projects – Provide three projects of similar size and complexity where the Offeror was the Prime Contractor. Referenced projects should be less than five years old.” Could this time period be extended to the last 8 years?

Due to the extremely demanding nature of this project we cannot extend the relevant time period.

2 Please provide the wage scale. The wage scale for this project is dictated by the requirements of the Davis Bacon Act. The location and type of project dictates use of Wage Decision DC180002 dated 05/11/2018. Offerors are hereby put on notice that the Smithsonian, in compliance with relevant federal law, will update the wage decision in the event that WD DC180002 dated 05/11/2018 is superseded during the bid period and if superseded prior to award. Please monitor www.wdol.gov for updates.

3 Please advise if the AE Team has modeled the project? If so? Can the model be made available to “Bidders” as soon as possible?

The project has been modeled. The model isn’t part of the construction contract documents, but will be made available to the

Contractor that is awarded the contract.

4 In Specification Section 131300, section 2.20. Please clarify if it is the intent of this section that all the Pool Style Pump motors, fractionator injector pump motor, regenerative blower parts (motor, housing, intake filter, intake silencer & pressure relief valve) are to have the factory coatings removed, blast cleaned, and a new High Solids Epoxy coating which complies with 2.20, G, 1 a/b applied?

Pool Style Pump motors, Fractionator Pump motors, Blowers and

Blower system components should all follow the specifications under each specific equipment section. Selections should follow brand requirements.

5 The LSS Process Flow Diagram on Drawing sheets LS-603 to LS-607, please provide further information and/or a detail on the aeration fittings shown on the bottom of several of the ponds.

Please refer to detail 6 on drawing LS505 for specific information related to the aeration fittings in the ponds.

6 Please confirm the following items on Drawings A302,A500,A520 are a part of the contract: Mural in the Aviary; Natural sand at beach

(Aviary areas); Pelican shell mulch; Painting of shotcrete rockwork

It is the A/E teams' understanding that the A sheets listed in this question are actually referring to the EX series drawings and have been responded to with this understanding.

1.) The Aviary mural wall noted on sheet A302 as "by other" is the graphic wallpaper image and will be by others. The mural wall structure and finishes are part of the base building and identified in the architectural drawing sheets.

2.) The natural sand at the beaches in the aviary areas is part of the contract as noted on sheet EX520 and EX431.

3.) There is no reference to Pelican Shell mulch on these sheets or in the documents to the best of our knowledge. Please provide detail reference for us to better respond to your question.

4.) All painting and texturing of shotcrete is part of the contract.

See shotcrete spec. 033713.

7 In the Specifications there is a specification section 225201 “Fog

Production System”, section 2.4A.3 calls for a skid mount pump. The pump for the Fog Production system is not indicated on the plumbing schedule on Drawing P601. Please provide location for the fog production system pump.

The fog production system Skid mount pump and controls equipment is located in room Mech 017 along the east wall. Refer to note 14 on drawing P402. The RO system associated with the

Fog Production system is located in Dirt Room 027 notated as "Fog production RO system and tank" on Drawing 1/P402.

8 On Drawing P501 Detail 6 does not show the fog production machine but does show the brine tank and water softener. On the isometric plumbing drawing P601 the fog production machine is shown next to the water softener and brine tank. Please confirm the location of the fog production machine.

The water softener and brine tank detail on drawing P-501 is meant to be only for that system. The Fog production machine, while it is one of the items served by the softened water (TRW), is a separate entity and is physically located on plan adjacent to the water softener system.
