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 #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 #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.
