The government is responsible for the wrapping, packing, and tagging of these items. They have been included in the set for coordination purposes.

Plan MD101 note 2 says the demolished equipment will remain property of the government. Contractor will consult with contracting officer for direction on proper disposal or storage of all demolished equipment. Please provide a list of equipment. Please advise – how should we bid this item of work if we are unsure if the government will want to keep or dispose of equipment? If the government wants to keep, who is transporting the equipment?

Where?

Demolished equipment noted on MD101 will not remain the property of the government and may be disposed of in accordance with 01 74 19 Construction Waste Management and Disposal and any other applicable specifications.

However, if material(s) that may be hazardous to human health upon disturbance are encountered during construction operations, contractor shall respond in accordance with 01 35 26." See paragraphs 3.1.3 of that section.

SD101 and S-501 – is the intent to protect the welded wire fabric in place when removing the existing 4” slab? Contractor cannot create a clean edge without removing reinforcing. Contractor cannon reinstall vapor barrier, base, piping, etc. without removing reinforcing.

Ref. 1/S-501. 12" minimum of existing slab reinforcement to remain on all sides of slab demo.

SD101 and S-501 – is the intent to protect the existing reinforcing and leave in place while removing the existing 6” slab? Contractor cannot create a clean edge without removing reinforcing.

Contractor cannon reinstall vapor barrier, base, piping, etc. without removing reinforcing.

Ref. 1/S-501. 12" minimum of existing slab reinforcement to remain. Note 3 on 1/S-501 indicates that at 6" (min) slabs, at Contractor's option, existing reinforcement may be removed and #4 dowels at 18" o.c. to be drilled and epoxied with 6" minimum embedment.

S-501 Detail 1 Note 3 – Confirm drill and epoxy dowl is at contractor’s option? So there is no requirement to drill and dowel?

Drill and dowel is not required when 12" minimum existing slab reinforcement is maintained as shown on 1/S-501.

S-501 Detail 1 Note 2 – there are sections on SD101 that are wider than 6’0”. Please advise – Note 2 states to contact Contracting Officer for Direction. We are requesting direction.

SD101.

S-501 Detail 1 – Does the 4” slab replacement require WWF when we replace or does it require #4 @ 18” O/C EW?

#4@18" O/C EW

SD101 – some of the 6” slab demolition areas are 1’ wide, it will be impractical to drill and epoxy dowels in these locations. Please advise.

Drill and epoxy dowels are not required. Maintain existing slab reinforcement per 1/S-501.

Please confirm retrofit measures in seismic evaluation report are reflected in the project drawings. Meaning, if retrofit measures are NOT part of the Design-Bid-Build drawings, but may be in the seismic evaluation report, then the Government will not require that measure as part of the project.

The plans show an existing 300 LB, (2) ¼ Ton, (2) ½ Ton monorail hoists. The keynotes on S-111 ask for a new 1/2T and 1T electric hoist. Can you clarify which monorail hoists are being replaced?

How are the existing monorail hoists being electrified?

The 1/2 ton and 1 ton monorail hoists identified with keynotes 3 and 4 on sheet S-111 are the two hoists to be replaced.

Existing monorail hoists to remain are not being electrified. The two new electric hoists are being electrified as shown on sheet E-103.

Chain hoists are more typical for such low capacities, most vendors sell a 2T minimum. The specifications look like they were pulled from a project with a higher capacity requirement.

Electric chain hoists can be provided at Contractor's option.

Electric chain hoist shall conform to ASME HST-1, NEMA ICS 8, NEMA MG 2, and NEMA ESPG. Hoisting chain shall be welded link load chain, include a chain stop or dead end connection to prevent the load chain from running out of the hoist at its fully extended position, and for chain hoists with 3 m (10 foot) lift or more provide a load chain bucket.

Local Concrete Ready Mix Suppliers do not stock or utilize Class N Fly Ash or Ultra Fine Fly Ash. Please revise this specification, as written currently, we cannot provide concrete that meets the specifications from local suppliers. This quantity is not large enough for them to bring in Class N or Ultra Fine Fly Ash, that would be cost prohibitive.

Specification does not specifically require Class N Fly Ash or Ultra Fine Fly Ash to be utilized in the concrete mix. Class N Fly Ash and Ultra Fine Fly Ash are not required.

Plans call for proper collection and offsite disposal of existing AFFF foam (reference FD001 Note 19, as well as Notes 4 & 18). This is a significant task. As it appears that the AFFF Concentrate Tanks are full (as well as potentially the closed-head overhead fire sprinkler systems), please describe the required method of preparing the piping for “clean pipe” demolition. If detailed specifications are not available (none are currently included in the bid documents), please confirm that draining all Tanks and piping of contents (AFFF Concentrate & Solution), followed by triple-rinsing of all piping now or formerly in contact with AFFF (basically all piping), followed then by Lab analysis of Concentrate and rinse water (all AFFF is already know to contain PFOA & PFOS), and finally offsite (out-of-state, since no in-state facility accepts AFFF) disposal, as otherwise outlined in Note 18 (note that this will require venting and draining of all branch lines as they are the highest piping components that do not readily / fully fill and drain).

The proposed procedure outlined in the question is acceptable.
