SOLICITATION: RFP F15SOL10010

SI RFI Number Date Company Request for Information SI Response

S001 4/9/2015 Grunley 1 Section L.13.5 (page 60) of the RFP indicates that submissions should be "tape bound only." We understand the Smithsonian Institution's desire to minimize the receipt of bulky proposals (i.e. three-ring binders) and maximize recycling potential. However, the specialized equipment required to perform tape binding is rarely owned in-house thus would require coordinating with outside printing vendors with long processing times (3-

4 days before the proposal’s due date). In order to tape bind the proposal volumes, offerors will have to complete their technical and pricing proposals several days prior to the submission date and deliver them to a reprographic company for binding. This process will drastically reduce the offeror's ability to select the most advantageous subcontractors and guarantee the lowest pricing for the Smithsonian. We respectfully request the ability to use one of the following alternatives in lieu of tape binding: spiral binding, comb binding, ACCO metal binding clips, and/or banker’s clips.

Spiral binding and comb binding are also acceptable.

4/9/2015 Grunley 2 Section L.13.9, section 2, indicates that the offeror should include fill-in information in

Sections G and H. Section G requests key personnel information, but Section H does not appear to have any fill-in information requirements. Please clarify these requirements.

The reference to Section H is an oversight on our part. Please be mindful that Section

K contains certifications on responsibility matters (pp.49-53) which do contain fill-ins.

4/9/2015 Grunley 3 Please reference the drawing table of contents. All of the mechanical drawings on the

TOC that have the “A” sequence and “Attic” title do not match the drawings provided.

The drawings all utilize either a “4” or “P” sequence and “4th Floor” or “Penthouse” title. Please confirm that the mechanical drawings are correct as issued.

The mechanical drawings are correct as issued. The drawing index sheets G-002 and G-

002A have been revised to match the mechanical drawing titles and are included in

Addendum #1.

S002 4/14/2015 Clark 1 Specification Section 211313 (Wet Pipe Sprinkler Systems) references Specification

Sections 211000 and 211100, which are not listed in the set of specifications provided.

Please provide or clarify.

The reference to 21 10 00 and 21 11 00 is not applicable for this project and may be disregarded. Delete specification section 211313, 1.01 B3 regarding the general requirements reference. Delete the last sentence of 211313, 1.04A since there is no exterior work required by this project

4/14/2015 Clark 2 Spec 093033 - Drawing A 1.43 general note B states ” Patch and repair marble floor tiles, reset loose or uneven tiles”. No qualifications which will tell the bidder how much would be required. 20% or 50% of the floor?

Assume 100% of the floor requires patching and repair.

4/14/2015 Clark 3 Spec 093033 - Drawings A 1.11- A1.14 note 4 refers you to 1/ A5.53 states” new base”, are all of the columns to receive new base or are we to salvage the existing and reuse?

Most of the original column surfaces are covered and are not visible. The presence and condition of the existing base cannot be evaluated. Some of the base may be salvaged, however the amount that may be salvaged is unclear at this time. Refer to specification section "Allowances" and "Unit Prices" for additional information.

Please see response to comment 5 for more information about column stone base.

4/14/2015 Clark 4 Spec 093034 - Drawings A 1.11- A1.14 note 60 states “patch and repair existing stone base, where missing replace per original building design”. Not quantified. Is the 1000 lnft going to account for the missing base? No quantity of repairs required on existing.

The quantity of stone base listed in the "Allowances" specification (012100, 3.3 A 2) is intended to estimate the amount of replacement required. Any quantity beyond the estimated allowance will be subject to the unit price. Please refer to specification section "Unit Prices."

4/14/2015 Clark 5 Spec - 093035 - Drawing I 1.00 general finish note 9 states” any existing stone to be salvaged for reuse, coordinate with COTR for any stone reinstallation”. The demo drawings do not indicate where marble base is to be removed. Is it correct to assume the base removal is in combination with the note 12 on Drawings A 1.2D- A1.7D? Note

12 states ”remove multi coat plaster on columns down to terra cotta”. The majority of the columns in this museum have stone base. Please clarify where the stone is to be salvaged from.

If stone base is present on the walls, it should not be removed. It should be repaired as required. If stone base is missing, new stone base to match the original should be provided and installed. Original columns may have existing stone base. The condition of the stone base is unknown at this time and cannot be evaluated since most of the original column surfaces are covered.

Removal of the multi-coat plaster will require the removal of the existing stone base if it is present. Once removed the stone base should be salvaged and reinstalled once the new plaster finish is applied. If no stone base is present once the original column surface is exposed, new stone base to match the original shall be installed.

4/14/2015 Clark 6 Spec - 093036 - Drawing I 1.00 general finish note 10 states “All concealed existing stone wall base to be cleaned & repaired to remain, including areas behind new partitions” Repairs not quantified. Please provide quantification for repairs.

Assume all existing wall base shall be cleaned and repaired to restore the finish to an acceptable level. Refer to specification sections "Allowances" and "Unit Prices" for new base.

4/14/2015 Clark 7 Dwg SG-0-01 states that the Seismic Design Category is B. Please confirm seismic restraints are not required for mechanical, plumbing, and sprinkler systems.

Seismic restraints of mechanical, plumbing, and sprinkler systems are not required for

Seismic Design Category B per Chapter 13 of ASCE 7-10 (as referenced by IBC 2012).

4/14/2015 Clark 8 Spec 211313 - Specification does not specify steel type for sprinkler pipe. Please clarify. Section 1.07 B 1 a calls for Piping is to be per: A53 Pipe, Steel, Black and Hot Dipped, Zinc-Coated, Welded and Seamless. Black steel will suffice.

Section 2.03 E calls for Schedule 40 steel for piping < 4-in and Sch 10 or 40 for larger pipe sizes. Also please note all exhibit space piping to be minimum schedule 40 per

General note 8 on drawing FP 0 01.

4/14/2015 Clark 9 Specification 211313 refers to the Fire Detection and Alarm System Specification as

Section 238111. Please confirm it should be Section 283111 in lieu of Section 238111.

Yes. This is a typo. “238111” should read “283111”. Revise specification section

211313, 1.01 B1

4/14/2015 Clark 10 Can a quantity of asbestos containing drywall be provided. See Specification Section 02

TEMPERATURE SENSOR FOR EVERY REHEAT COIL, FAN COIL UNIT, TRANSFER FAN, AIR

VOLUME CONTROL BOX AND FINNED TUBE RADIATION”, while on M805 detail 1 and

MP1102 (other floor plans as well), there are multiple AVBs and FTRs sharing common

“T” (thermostat/temperature sensor), “CO2” (carbon dioxide sensor) and “H” (humidity sensors). Is the intent to have one “T”, one “CO2”, and one “H” per AVB/VAV/TU and one “T” per FTR or are the sensors limited to those shown on the floor plans?

(a) The intent of this note is to require an individual temperature sensor for each listed device, except where floor plans or control diagrams specifically indicate that a single sensor is to serve multiple devices. (b) Only one space humidity sensor and one space CO2 sensor is required per exhibit Hall as indicated by Detail 1/M805.

4/29/2015 Consigli 7 On M808 detail 6 depicts a duct mounted temperature sensor, not a wall mounted “T”, for control of the TFs and FTRs that serve the “window pockets”/service corridors, while the floor plans, for example MP1102 indicates wall mounted “T” for control. Are the TFs & FTRs to be controlled by wall mounted or duct mounted “T”?

The TF's & FTR's serving the "window pockets" shall be controlled by the duct mounted temperature sensors as indicated by the associated control diagram. The wall mounted sensors shown in Service Corridor # 4D, 4E & 4F are to be eliminated.
