Inquiry #7: Special Provision Section 55 “Steel Structures” lists the galvanized catwalks as being included in this section. There are many Section 55 requirements that do not apply to this type of construction (i.e. all welding per D1.5 Bridge Welding Code, inspection requirements, etc.). Requiring the catwalks to be fabricated per Section 55 unnecessarily increases the cost of the project. We feel the catwalks should be included in Special Provision Section 75 “Miscellaneous Metal”. Please advise.

Inquiry #10: Special Provision Section 57-4.01C(4) requires the fiberglass reinforced grating installer to provide documentation of at least 5 completed installations in the last 5 years. This requirement is highly unusual and would severely limit the number of contractors / subcontractors able to bid this project. The FRP grating installation on this project is very simple as there is no field cutting or modification of the grating required. We request that this experience requirement be removed.
Inquiry submitted 12/15/2017
Response #1:Please bid per current contract documents.
Response posted 12/15/2017
Inquiry #11: This project currently has a 12% DBE goal. Typically on bridge painting projects we can use non-painting items like traffic control to meet DBE goals. This project does not need enough traffic control to even come close to meeting the 12% goal. Our DBE searches have not yielded a DBE structural steel fabricator/installer that can handle the structural steel/catwalk portion of this project. Painting cannot be subcontracted to a DBE painting contractor unless they are also SSPC QP1 and/or QP2 certified. We will hopefully be able to find DBEs for the other miscellaneous non-painting work, but all of that combined does not come close to representing 12% of the contract value. We request the DBE goal should be significantly lowered to something reasonably achievable. Please advise.
Inquiry submitted 12/21/2017

Inquiry #30: Sheet 4 of 33 of the drawings shows a 20' wide access area under Location 3. There is a tenant on both sides of that access area from Bent 207 to Bent 211. We have to have temporary areas of access at each bent for forklifts and manlifts in order to install the temporary platform. It cannot be done by only using a 20' wide strip of land under the middle of the bridge. When we are installing platforms, we need to cordon off the areas on the ground under the leading edge of the platform for safety so that if something were to accidentally drop, no one on the ground is injured. Additionally, doing a large complete abrasive blast lead abatement job like this takes a huge amount of equipment (dust collector, vacuum, compressors, generator, blast pot, shipping containers for secure storage, etc) and staging/storage for new abrasive and waste storage for hazardous waste spent abrasive. We need more accommodation at the site than the specified 20' wide strip. We request that the specified area for temporary use be expanded to Bent 210 and Caltrans secure agreement from the tenant that the contractor can coordinate temporary access to the rest of the yard as needed for platform installation, including isolating areas directly under the leading edge of platforms being installed or removed for safety reasons. Please advise.
Inquiry submitted 01/25/2018
Response #1:The designated work area shown at Location 3 was established for the exclusive use of the Contractor during the construction of the project. The size of this area has been intentionally limited to allow the existing airspace lease tenant to be able to continue with business operations during the construction of the project. Within airspace lease areas that are outside of the designated work area, temporary clearing of the ground area under the leading edge for platform construction may be arranged with the Engineer. At location 3, additional staging areas or storage yard space that is exclusive to the contractor will not be provided.
An area outside of the contract limits, for the exclusive use of the contractor, as show in the information handout drawing included in Addendum No. 5, may be made available subject to the conditions identified in the drawing.
Response posted 01/26/2018
Inquiry #31: Sheet 5 of 33 of the drawings shows a 20' wide access area at Bents 239, 244, 247 and 251 under Location 4. This is not nearly enough space to accommodate our needs for staging platforms and scaffolding parts, blasting and painting equipment, paint storage, new abrasive storage, hazardous waste storage for spent abrasive etc. Additionally, we have to have temporary areas of access at each bent for in order to install the temporary platform. It cannot be done by only using these 20' wide strips of land that are spaced so far apart. When we are installing platforms, we need to cordon off the areas on the ground under the leading edge of the platform for safety so that if something were to accidentally drop, no one on the ground is injured. Additionally, doing a large complete abrasive blast lead abatement job like this takes a huge amount of equipment (dust collector, vacuum, compressors, generator, blast pot, shipping containers for secure storage, etc) and staging/storage for new abrasive and waste storage for hazardous waste spent abrasive. We need more accommodation at the site than the specified 20' wide strip. We request that the specified area for temporary use at Bent 239 be expanded to include an area on the West side of Bent 239 approximately 50'x200'. We request that the staging area at Bent 244 be expanded by an adjacent area approximately 50'x200'. We request that additional staging area be provided as well at Bents 247 and 251 and that Caltrans secure agreement from the various tenants that the contractor can coordinate temporary access to the rest of the areas as needed for platform installation, including isolating areas directly under the leading edge of platforms being installed or removed for safety reasons. Please advise.
Inquiry submitted 01/25/2018
Response #1:The designated work areas shown at Bents 239, 244, and 247 at Location 4 were established for the exclusive use of the Contractor during the construction of the project. The size of these areas have been intentionally limited to allow either the railroad yard or the airspace lease tenants to be able to continue with business operations during the construction of the project. Within the railroad yard or airspace lease areas that are outside of the designated work areas, temporary clearing of the ground area for construction of the platform leading edge may be arranged with the Engineer.
At Bents 239, 244, and 247, additional staging areas or storage yard space that is exclusive to the contractor will not be provided. Temporary staging or temporary storage of equipment and materials on State property outside of the railroad yard or airspace lease areas, may be arranged with the Engineer, subject to the prior needs of the State and to other contract requirements.
The designated work area shown at Bent 251 was also established for the exclusive use of the Contractor during the construction of the project. Since this designated work area is not within a railroad yard or existing airspace lease property, additional temporary staging or temporary storage of equipment and materials on State property may be arranged with the Engineer, subject to the prior needs of the State and to other contract requirements.
An area outside of the contract limits, for the exclusive use of the contractor, as show in the information handout drawing included in Addendum No. 5, may be made available subject to the conditions identified in the drawing.

Inquiry #42: Bidder inquiry #38 confirms that new fasteners cannot be galvanized. One option is to use black bolts and abrasive blast and prime bolts and nuts after installation. This is not an attractive option because bolts and nuts have be blasted from a lot of different angles and the overblast will damage nearby previously applied coatings on structural steel as well as galvanizing on new catwalk members. Additionally, it will add a significant cost to the project due to the labor cost of doing this and fixing the collateral damage it will cause in the vicinity of bolted connections.
To avoid this issue during construction of the new Self-Anchored Suspension Span of the San Francisco-Oakland Bay Bridge, fasteners coated with Geomet-500 were used. After installation, a Geomet coated fastener simply needs to be solvent cleaned prior to being finish coated with the bridge coating system. Geomet is a chrome free alternative to the older Dacromet 500 high strength fastener coating.
Geomet provides corrosion protection to high strength fasteners where galvanizing cannot due to the hydrogen embrittlement associated with galvanizing high strength steel.
Please confirm that Geomet-500 coating of high strength fasteners will be acceptable for this project.

Inquiry #43: Ref. Sheet 24 of 33, “Partial Girder Plan”; Section C-C is called-out at the locations where there is no existing L4x4 cross frame member and a new W6 cross frame member is to be added. Section C-C on sheet 25 of 33 calls-out Detail A at the left end of the new W6. Detail A does not apply here as there is no existing L4x4 member or horizontal gusset plate at this location. We assume the section C-C call-out at the left end of the W6 should instead be Detail B (Sim), Sheet 26 of 33. Please confirm this is correct
Inquiry submitted 03/07/2018
Response #1:Bid per current contract documents. Reference plan sheets 21 and 22 of 33 for locations of removing and replacing existing with new cross-frame members, and placing new cross-frame members. Reference plan sheets 24, 25, and 26 of 33 for different cases of new W6x12s attachment details.
Plan sheet 25 of 33, Detail A applies when a new W6x12, with respect to section C-C, is attached to locations that have existing wind bracings.

Inquiry #52: Please clarify Caltrans response to Inquiry #47. Define the term "Steel Collar". Also, is it Caltrans intent to abrasive blast and paint the steel column casings? If the steel casings are required to be painted, please provide the quantity of columns that have steel casing around them, the size of the columns as there are multiple configurations of columns, the height of the columns that would require to be painted as each one is different. Caltrans has denied the contractor access to assess or inspect the majority of columns. Due to the limited access, it is impossible to determine which columns are concrete and which have steel casings without getting immediate access. Caltrans has not provided any of the column or "steel collar" details or quantities on the drawings and specifications which would be needed to bid responsibly. Furthermore, is it Caltrans intent to abrasive blast and paint the seismic retrofit appurtenances too? If so, the same details would be needed as listed above for the columns. If the casings and retrofit appurtenances are required to be painted this bid needs to be postponed until quantities, details, and/or access is provided to assess these items.
