Inquiry #3: When the lift span is moving up and down can the work crew stay on or around the towers, on area's not related to active face?

What is the maximum wind load that can be applied to the lift towers?

There are areas on the bridge where a complete containment system, a system that meets the written specifications, cannot be installed due to shortened work times or unplanned interruptions(example the outer face of the tower where the lift span travels up and down). Will Caltrans allow a hand wash/hand clean in lieu of the specified steam clean, pressure wash, and or spot blast followed by the application of the specified PWB system?

Response #1:Your inquiry has been received and is being reviewed.
Response posted 07/21/2017


Response #2:
Your attention is directed to the "NOTICE TO BIDDERS" which states in part:

Prevailing wages are required on this Contract. The Director of the California Department of Industrial Relations determines the general prevailing wage rates. Obtain the wage rates at the DIR website, http://www.dir.ca.gov, or from the Department's Labor Compliance Office of the district in which the work is located.

The federal minimum wage rates for this Contract as determined by the United States Secretary of Labor are available at http://www.dot.ca.gov/hq/esc/oe/federal-wages.

If the minimum wage rates as determined by the United States Secretary of Labor differs from the general prevailing wage rates determined by the Director of the California Department of Industrial Relations for similar classifications of labor, the Contractor and subcontractors must not pay less than the higher wage rate. The Department does not accept lower State wage rates not specifically included in the federal minimum wage determinations. This includes helper, or other classifications based on hours of experience, or any other classification not appearing in the federal wage determinations. Where federal wage determinations do not contain the State wage rate determination otherwise available for use by the Contractor and subcontractors, the Contractor and subcontractors must not pay less than the federal minimum wage rate that most closely approximates the duties of the employees in question.


The wage rates are determined by the Department of Industrial Relations based on the classification of work being performed along with the county that the work is being performed in. Caltrans will enforce the wages required per classification of work being performed and the county the work is performed in.

Inquiry #15: Since the work staging is 2 bays at a time, does Caltrans consider work in each 2 bays a new balance condition requiring a Balance Test, Operational Test, and counterweight shift?
Inquiry submitted 08/11/2017

Response #1:Your inquiry has been received and is being reviewed.
Response posted 08/11/2017


Response #2:
If work staging is performed 2 consecutive bays at a time from one end of the span to the other, each stage shift will cause an unbalance condition and the answer is definitely yes.
If work staging is performed on 1 bay at each end of the span and each stage shifts inward one bay maintaining a balanced condition, then the answer is probably no depending on any loading changes.

Response posted 08/15/2017




Inquiry #16: Without knowing exactly what Caltrans is doing with the power recordings and how they are converting it to load, it is difficult to assess Caltrans method of Balance Testing. A concern of ours is that the nominal power to operate the bridge reflects the imbalance AND the friction, as well as any power losses. (a) If there are fluctuations in friction and/or power losses, are these being removed from the analysis? With the strain gage method, friction is quantitatively determined independent of imbalance, so that the result is in fact imbalance. (b) Will Caltrans consider using the strain gage method?
Inquiry submitted 08/11/2017

Response #1:Your inquiry has been received and is being reviewed.
Response posted 08/11/2017


Response #2:
Yes. The strain gauge method can be used for balance testing. Caltrans will still use the power meter method in concurrence with the strain gauge testing to double check the results.
Response posted 08/15/2017




Inquiry #17: Will Caltrans allow the Contractor to perform an independent balance check at the outset and the completion of the project using the strain gage method?
Inquiry submitted 08/11/2017

Response #1:You inquiry has been received and is being reviewed.
Response posted 08/11/2017


Response #2:
Yes, the Contractor may use the strain gauge method to perform an independent balance check at all four drive shafts at the outset and completion of the project. Strain gauges and connectors should be left in place for the entire duration of the project. (see inquiry 18)
Response posted 08/15/2017




Inquiry #18: Will Caltrans provide the balance test for the starting condition of the bridge to substantiate the end imbalances that are provided in the project specification in the contractor’s presence in order to demonstrate the initial balance?

Response #1:Your inquiry has been received and is being reviewed.
Response posted 08/11/2017


Response #2:
Yes, Caltrans will provide a balance test using the power meter method with the contractor present to verify imbalances as provided in the specification. The contractor may provide a concurrent strain gauge test if desired to verify Caltrans’s test results. (see inquiry #17)
Response posted 08/15/2017




Inquiry #19: With the project requiring night work and limiting the area where the contractor can work due to the SPA zones, will Caltrans recommend a different paint system, that can be applied to the bridge. We have reviewed the historic weather conditions for this area. The humidity and low temps are a concern with the PWB system.

Inquiry #24: Dear Sir:
I am afraid that I did not make my inquiry, Inquiry #22, clear. What I wish to have clarified is the following:

“By which trades, as described in the Davis Bacon Act, would the California Department of Labor determine that the following work should be performed?”

1. Erection and dismantling of the suspended work platform beneath the deck to contain the spent abrasives and lead debris. Should this work be performed by carpenters, painters, or laborers?
2. Erection and dismantling of systems scaffolding that is erected to access the structural steel and to support the tarps that contain the spent abrasives, lead paint, and paint overspray from repainting operations. Should this work be performed by carpenters, painters, or laborers?
3. Erection and dismantling of the tarps that contain the spent abrasives, lead paint, and paint overspray from repainting operations. Should this work be performed by carpenters, painters, or laborers?

Our firm is an open-shop contractor. On California Department of Transportation projects that we have performed for Caltrans, the California Department of Labor has required that we pay carpenter’s wages to those employees performing work items 1 and 2 above but has allowed us to use painters to perform work item 3. Pursuant to a Freedom of Information request, we have been reviewing the payrolls of Contractors signatory to painting union agreements and have discovered that almost none of the workmen on union contractor payrolls are paid the carpenter’s wage to their employees performing work in item 1 or 2, but are paid the painter’s wage instead. The painter’s Davis Bacon wage scale is nearly always significantly lower than the carpenter’s Davis Bacon scale. In addition, painting contractors that are also signatory to agreements with the Laborer’s Union often pay the workmen performing work as outlined in item 3 the Davis Bacon scale for a laborer, which is oftimes considerably lower than the painter’s scale.

It is very important that a decision clarifying the above questions 1-3 be issued before this project bids next Wednesday, 23 August, 2017. If the California Department of Labor is unable to clarify this before then, I request that the California Department of Transportation postpone the bid opening until it is clarified. The way that the California Department of Transportation unfairly treats open-shop contractors on these contracts is unfair to open shop contractors and gives a substantial competitive advantage to union contractors.

If we do not receive clarification of this matter, or if the bid opening is not postponed pending such resolution, we will be forced to file a pre-bid protest of seek injunctive relief, which is expensive for all parties involved.
