Inquiry #4: 1. Bid Item 20 Reconstruct Metal Sidewalk (Bridge) is unclear as to the scope of this work. Is the sidewalk being removed for access to the roadway grading & then reinstalling the existing sidewalk?

2. Sheet 10 of 27 shows detail A, view C-C and section D-D but does not show where the sections were taken from.

3. The description of the counter weight block is very vague, can a drawing be provided?

4. Can a contractor site visit be arranged to see the extent of repair to the counter weight & condition of the existing counter weight balance blocks?

5. Spec. Page 7 states (do not start work before July 1, 2013 however in the information handout Caltrans Letter to the Coast Guard states work to commence June 15, 2013 & completed by Sept 15, 2013 please clarify.

6. The fabrication & delivery of the counter blocks & roadway grading is approximately 5 months, as such we would not be able to complete the contract in 100 Working Days. Please increase the contract duration to 200 Working Days to allow for the fabrication & installation time.

7. Please postpone bid date by at least 1 week.

Inquiry #5: On page 30 of the Special Provisions, section 59 Painting, Add to section 59-2.01A states "Paint new & existing steel members and blast clean and paint undercoat at locations shown on the plans"

This seems to require painting of the entire bridge, as existising steel members, and the plans do not indicate any specific members or areas to paint, which would narrow the scope.

The engineers estimate of $1.5 Million seems very low to paint the entire bridge. Please clarify what is to be included in Bid Item #25 - Clean & Paint Structural Steel.

Inquiry #6: Sheet 5 calls out the main grating bars as 2-1/2 x 3/16. A grating supplier noted that this product is NOT recommend for rolling loads and is no longer in the product line. Will 2-1/2 x ¼ be acceptable? This obviously would add more weight.

Inquiry #7: Per the specs, the grating panels are to be galvanized after fabrication. This will pose a problem with the E panels called out on sheet 4 as there is no way to access to tighten the bolts. Is it permissible to weld the grating on after installation of the supporting plates?

Inquiry #8: There is a conflict with the steel bridge deck specification.
Plan sheets 12 and 13, Part Plans call out bridge decking with 3/16"x 2 1/2" bearing (main) bars.
Special Provision 55-4.01D dictates compliance with ANSI/NAAMM MBG 532-09. This manual covers bearing bars between 1/4" and 3/8" thick. 3/16" bearing bars are not covered by this manual.
Should we bid 3/16" bearing bars and not comply with MBG 532 or should we bid 1/4" bearing bars?
1/4" bars will add about 11,000 lbs. of weight to the lift span.

Inquiry #9: Sheet 10 of 27 states that the “Sidewalks must be reconstructed to facilitate steel bridge deck grate replacement” and calls out “reconstruct” on all of the individual components of the sidewalk structure. Section 15 of the Special Provisions states the sidewalk is to be "refabricated". We assume this reconstruction/refabrication is nothing more or less than painting as required and new hardware required for reassembly. Is this correct?

Inquiry #10: Sheet 14 of 27 calls out the replacement of the C12X20.7 skid rail. The existing rail to be replaced has an attached stiffening castellated WT section welded to it. Is that also to be matched on the new skid rail? If so please provide detail.

Response #2:3/21/13: On sheet 7, the Skid Rail Detail shows the C12 X 20.7 is bolted to a 3/8” bent plate. The plans do not show stiffening castellated WT section welded to the C12 X 20.7. Bid per the current contract documents.

Inquiry #11: As can be seen in the field, everything is welded to everything else:

-All of the sidewalk components are welded to each other (A-A & B-B on Sheet 10)
-Channels welded to Sidewalk support plates (B-B on Sheet 10)
-Some panel channels to stringers (Sheet 9)

Some of these welds will have to be removed to accomplish the work. 15-4.03C states that burning rivets will not be permitted, however weld removal is not addressed. Can the air arc gouging method be used in removing the required welds?
