SECTION 10-6.8 BLASTING – 10-6.801 PART 1 – GENERAL – BLASTING SYSTEM DESIGN Page 556, second paragraph. "Blasting shall conform to the following:
The particle velocity limits from the time of batching will conflict with the shotcrete placing required in Categories I, II and III as the placement of shotcrete is required to be completed for each round excavated prior to blasting the next round in the heading advance. The 13 mm/sec, the 25 mm/sec, and the 50 mm/sec peak particle velocities may be impossible to achieve unless the next blast in the heading is delayed until the time limits have been achieved. As a given delay could be as long as 3 to 7 days per round, is this delay time part of the intention of the specifications? This specification requirement is not present in SEM tunnel excavation specifications that require blasting for excavations. |
Item C has been deleted from SP 10-6.801. However, page 9 of Addendum #2 erroneously refers to Section 10-6.308. Addendum #2, page 9, third paragraph should read: "In the Special Provisions, Section 10-6.801, "PART 1-GENERAL," subsection, "BLASTING SYSTEM DESIGN," in the second paragraph, item C is deleted." |

Occupational Safety and Health Qualifications Section:
If this section is not deleted, please specify which insurance modifier will be used for this criteria, the National Council on Compensation Insurance (NCCI), the California State modifier, or some other modifier. Note that many contractors do not have a California specific modifier. Please consider deleting the words "may be determined to be nonresponsive and" from the above requirement. In particular, placing this requirement on all subcontractors of any tier is onerous. It will create an extreme burden on the bidding contractor at bid time to and will cause bidders to include contingency in their bid if they must replace a subcontractor who is deemed nonresponsive. The language should allow for the Owner to accept an additive change order if a subcontractor has to be replaced. Please consider amending this language to require only those with modifiers greater than 1.25 to be subject to this requirement for additional information. The 1.0 threshold will create a burden to the contractor, the owner, and the OCIP administrator due to the number of contractors and subcontractors who have a modifier exceeding 1.0. This requirement could also cause the number of bidders to decrease as firms are discouraged from bidding to avoid the burden of this requirement. |
A Self-Insured Contractor will provide its certificate of consent to Self-Insure in place of its Experience Modification Factor, as clarified in Addendum 4. The Contractor and Subcontractor of all tiers shall submit their current Experience Modification Factor as calculated by the California Workers Compensation Insurance Rating Bureau (WCIRB) or the National Council on Compensation Insurance (NCCI), whichever is applicable for the work, as clarified in Addendum 4. Government Code 4420 requires the Owner to consider Contractor’s and Subcontractor’s Experience Modification Factor for participation in the OCIP program but does not specify a threshold level before a contractor is considered non-responsible. The determination of the threshold is at Caltrans discretion. Addendum 4 clarifies that “non- responsive” in the section refers to the failure of the contractor to submit supporting documentation only. The Contractor’s obligation to replace a non-qualified subcontractor will be at its own expense, as indicated in Addendum 4. Addendum 4 changed the experience modifier from 1.0 to 1.25. |

Contractor Insurance Cost Identification Section:
"Department expects the Contractor's insurance costs included in their bid and then detailed on CT OCIP Form 1 to be also based upon first dollar coverage rates. The Contractors and subcontractors of all tiers with insurance programs shall use the following for their calculations:..." |
Refer to Addendum # 4 for revised language. Self- Insured contractors and contractors with high retentions have access to manual rates charged by their insurance company with no deductibles. Manual rates (or "base rates") can be provided by the contractor's current Workers' Compensation carrier or accessed via the CA Dept. of Insurance website. The OCIP Administrator can help with unusual situations where such manual rates may not be readily available to the contractor. |
|

"A. Deductible or self-retention credits or self-insured amounts may be identified in the contractor's credit calculation but will not be allowed for inclusion in the contractor's and subcontractor's of all tiers OCIP deduct rates." Please consider deleting or amending this language. If such credits are not allowed in the calculation of the deduct credit, the results of the savings that the OCIP provides is not accurate. If a contractor were awarded the project without an OCIP in place, their retentions and credits would potentially reduce the cost of insurance for the project. Therefore, all this language will do is increase the bid amounts by the same proportion as the deduct rates will be increased. |
Refer to Addendum # 4 for revised language. The Department is providing workers’ compensation, general and excess liability coverage with no deductibles (except the potential GL obligation) for the Contractor and subcontractors of all tiers. Contractors shall identify their costs and rates for equivalent coverage. |
|

"Corporate allocations will not be allowed. The same format for calculation as shown for composite rates must be shown on CT OCIP Form 1." Please consider deleting this section in its entirety an accept all costing submissions provided by the contractors. Evaluation and acceptance of the deduct credit should be done on a case by case basis after the bid process. Many large contractors are not subject to standard rating and each loss sensitive program has its own rating and cost structure. |
Refer to Addendum #4 for revised language. Contractors with corporate allocations have access to manual rates charged by their insurance company with no deductibles. Corporate allocations will be identified but not allowed in place of the insurance company rates. The OCIP Administrator is familiar with loss sensitive rating and cost structures and will evaluate and accept each Contractor’s deduct credit on a case by case basis. |

"Any rate credits, other than credits for deductibles or self-retention or self-insured plans, or surcharges shown on the declaration or rating sheets will be used to verify the Contractor's actual cost and determine the OCIP deduct rates."

"The Contractor shall show 4 percent of its total subcontract value for each subcontractor's estimated insurance costs that are unknown at the time of the bid." Please clarify this section to confirm that this 4% in no way affects the bid amount nor does it serve as any deduct or other effect in the contract value, unless the Contractor or any listed subcontractor does not furnish the required information and documentation. |
As clarified in Addendum 4, the 4 percent default deduction does not affect the bid amount for bid evaluation and award. It will serve as a default deduct if the Contractor does not furnish the required information. |

Insurance Provided by the Department: "B.3. Deductible Assessment: $25,000 each occurrence: The Contractor or subcontractor primarily responsible for causing any loss shall be responsible for payment of the deductible assessment as determined by the OCIP insurance company." Such a deductible assessment can lead to a moral hazard with regard to nuisance claims. The contractor must be included in the claims notification and settlement process and must give approval prior to any settlement. Without this check and balance, the Owner may be inclined to settle claims at an amount just below the assessment and deduct from the contractor without due diligence to mitigate the claim. |
As clarified in Addendum 4, the responsible contractor or subcontractor will be notified of such claims and its input sought for claims investigation, but final determination of liability and payment will be made by the OCIP insurance carrier. The OCIP has been designed to ensure this “notification and settlement” protocol is observed. |

Contractor-Furnished Insurance: "For any work under this contract and until completion and final acceptance of the work, the Contractor shall furnish Certificates of Insurance to the Department, for itself and subcontractors of all tiers, evidencing the following coverages are in force on a primary basis. Please amend this section as enrolled contractors and subcontractors will not be providing on-site general liability, workers compensation, or excess liability insurance. These coverage requirements should be identified as off-site only. Only with this amendment can the coverages be in force on a primary basis. |
In Addendum 4, the OCIP specifications have been amended to require these certificates of insurance for coverages that are not provided under the OCIP insurance policies. |
|
123.0 |
"The Certificates of Insurance...shall set forth deductible amounts... and all exclusions that are added by endorsement to each policy." Please consider deleting the words "and all exclusions that are added by endorsement to each policy" as such a requirement will be overly burdensome to contractors with large insurance programs spanning many states and operations. The Owner is indemnified by the contractor and is providing the primary on-site insurance for the program. Such a requirement is disproportionate to the exposure. |

"E. Professional Liability...Professional liability insurance shall be maintained during the term of the contract and for so long as the insurance is reasonably available as specified, for a period of 10 years after completion of the services."

Current market conditions indicate that a total term of 10 years is the maximum available. |
Addendum 4 changed the required 10 years to 5 years. |

The following requested clarifications are from OCIP Manual: Page 3 General Liability Deductible Assessment (Obligation) & Page 10 - General Liability Obligation Although not unusual, such a deductible assessment can lead to a moral hazard with regard to nuisance claims. The contractor must be included in the claims notification and settlement process and must give approval prior to any settlement. Without this check and balance, the Owner may be inclined to settle claims at an amount just below the assessment and deduct from the contractor without due diligence to mitigate the claim. Please consider adding language to these sections indicating that the responsible contractor or subcontractor will be included in the notification and claim management process. Agreement to settle from the responsible contractor or subcontractor should be a requirement to settlement of a claim. |
As clarified in the revised OCIP Manual (October, 2006 Edition), the responsible contractor or subcontractor will be notified of such claims and its input sought for claims investigation, but final determination of liability and payment will be made by the OCIP insurance carrier. The OCIP has been designed to ensure this “notification and settlement” protocol is observed. |

Page 19 Safety Guidelines "The Contractor shall maintain total control of safety to ensure that its employees and the general public will be provided an environment free of recognized hazards during construction activities." Although making the Contractor responsible for safety is an obvious choice, including an incentive program for achieving safety goals would be beneficial to the success of the program. Since the Caltrans OCIP program may ultimately encompass many projects and Contractors, perhaps the best incentive plan would be a flat dollar bonus based on each day worked incident free. This incentive could possible apply to any enrolled contractor or subcontractor. For example, if a subcontractor worked on project for a total of 100 days incident free, that subcontractor would receive a bonus of $5,000 representing $50 per day for each incident free day. |
The Department is considering an incentive plan for this project; however, it is not obligated to do so. |

The textures and geometric shapes of the scallops at portals of the tunnels will require custom form liners with non-industry standard reliefs at over 11,000 M2 of surface area. Due to the fact that the textures vary at each end of the tunnel and the geometric shapes of the scallops are not typical, very little of the form liners will be able to be re-used. We feel the textures will add an estimated 3 to 4 million dollars of cost to the project. Does the owner intend to keep the aesthetic features as designed?

While soliciting painting contractors we have been told the specifications for the painting of the textured surfaces at the portals contains vast uncertainty. Most companies are not willing to bid the project. Painting professionals have stated the requirement to match the existing rock formations utilizing combinations of stain and paint while showing discolorations, cracks, and oxidation is impossible to predict with accuracy. Does the owner intend to keep the paint scheme as designed? Will the owner clarify with addendum the color scheme and provide a list of acceptable manufacturers of specified colors of the paint at the portals, inside cross passages, and equipment chambers as a good faith effort to remove uncertainty of this scope to allow more bidders to participate. | No further information will be provided.

The staining specifications require the stained concrete to be rinsed until the rinse water runs clear. We anticipate using a large magnitude of water to accomplish this. Due to the environmental concerns and bid specifications this water must be collected and treated. May the water be collected as it begins to run off from the area where staining is being applied and before it leaves the tunnel or must all water be collected before it lands in the invert? If the owner does not want any water to land in the invert while staining and rinsing then this will have major implications on cost of staining, temporary ventilation, and the overlap of other construction activities adjacent to staining operations. Will the owner clarify the level and method of collection desired with addendum? | No further information will be provided.

Refer to SP 10-5.02, "Tunnel Fire Protection". The Fire Protection piping specification section on page 436 requires the pipe exterior to be coated with a coal tar epoxy per AWWA C210. This cannot and will not be done. Our experience has proven that bonded coatings applied to the exterior of ductile iron pipe for buried service, for the most part, do not work. They are very expensive, problematic, and often lead to premature pipe failure. This is a severe enough matter that U.S. pipe has taken the stance that we will not provide pipe for buried service with any special bonded exterior coating. Nor will we provide pipe to others where we know a special coating is to be applied. Further, any unauthorized application of an exterior bonded coating will render our pipe warranty null and void. | Please see Addendum No. 6 dated 11/03/2006. |

The Leach Water system also requires the C210 coal tar epoxy coating. Since this system is an exposed installation it is understandable that you want a special coating. However, the C210 coating is designed for steel pipe, not ductile iron pipe. The common way to coat exposed ductile iron pipe (such as for gallery piping in a water treatment plant) is that the manufacturer can ship pipe to the job with a factory applied primer. Then, a finish coat of a variety of options is applied by painting contractor in the field. Field application of the intermediate and final coats is the only way to go, so that transportation, handling, and shipping damage that will occur is eliminated. | Please see Addendum No. 6 dated 11/03/2006. |

Occupational Safety and Health Qualifications: The specifications indicate that "The Contractor and subcontractors of all tiers shall submit their current Experience Modification as calculated by the ...(WCIRB) or the ... (NCCI), whichever is applicable for the work." Who determines which is applicable for the work and when will this determination be made? What if the bidder is a newly formed joint venture or a self-insured entity performing work solely in the State of California, thus having no rating modification from either of the above rating bureaus? |
The bidder determines which Experience Modification applies, depending on the payrolls he includes in his bid. If the bidder proposes to use California payroll, the California Experience Modification promulgated by the Workers' Compensation Insurance Rating Bureau (WCIRB) applies. If the bidder proposes to use payroll from states participating in the National Council on Compensation Insurance (NCCI) rating plan (for example, Arizona and Nevada), the NCCI Experience Modification applies. If the contractor proposes to use both California and NCCI state payrolls, then both Experience Modifications apply. If the bidder is a newly formed joint venture or a legally self-insured entity performing work solely in the State of California, and thus has no rating modification from either rating bureau, its Experience Modification will be assumed to be 1.00. |

Contractor Insurance Cost Identification: The specifications indicate that "...Corporate allocations must include the actual insurance company rating. ..." and that "Corporate allocations shall be identified but not allowed." This language appears to be contradictory and is confusing. Will corporate allocations be allowed as a means of identifying insurance costs if they include allocations for claims and fixed cost premiums to represent coverage with no deductible or retention? Will premium quotations from insurers meet the requirements for identifying insurance costs? (For example, a newly formed joint venture for the purposes of bidding this project would have no historical or current insurance policy from which to pull this information.) |
Bidders with corporate allocations shall identify both their corporate allocations (e.g. for paid and incurred claims and fixed cost premiums) and their insurance company manual rates with no deductible. The purpose of including both types of information is so that the OCIP Administrator can compare the allocations to and verify the bidders' insurance company rates. The Department's philosophy is that the OCIP provides workers' compensation, general and excess liability coverage with no deductibles (except the potential GL obligation). Corporate allocations may represent a different type of program (for example, based on paid claims only) whose structure is not equivalent to the Department's OCIP program. Therefore bidders are required to identify their costs and rates for coverage equivalent to the Department's OCIP. For a newly formed joint venture or other entity with no historical or current insurance policy from which to obtain rates, the bidder shall use the manual filed rates charged by its insurance company with no deductibles. Verified premium quotations from insurers meet the requirements for identifying insurance costs so long as the insurer's quotation includes the insurer's actual rates with no deductibles for every work classification. If no insurance company quotation is available, the bidder may use the rates filed by the California State Compensation Insurance Fund (SCIF). |

Failure to “…substantiate improvement in loss experiences…” being a cause for non-responsiveness is extremely onerous. The criteria is subjective and cannot be evaluated by the contractor. Therefore, all bidders (subs) with ERMs greater than 1 will have to be disqualified and this could cause reduction of bidders and increase in costs. | Prospective contractors and subcontractors with an insurance Experience Modifier greater than 1.25 (not 1.0, see Addendum # 4) are subject to scrutiny by the Department but not disqualified. If such contractor or subcontractor submits additional safety documentation that explains 1) why their Experience Modifier is greater than 1.25 and 2) the contractor's plan for substantiating improvement in loss experience, the responsiveness requirement is met. |

The structure of the deduct calculation does not allow for loss sensitive programs to be appropriately accounted for and since we must produce policies/copies for verification, obtaining project specific quotes on a guaranteed cost basis will not work. Please revise this section. | Addendum 4 provides guidelines for how contractors are to calculate their deducts under loss sensitive programs. The Department is providing workers’ compensation, general and excess liability coverage with no deductibles (except the potential GL obligation). Contractors are required to identify their costs and rates for equivalent coverage. Contractors need not obtain project specific quotes on a guaranteed cost basis. Contractors will usually have access to manual filed rates charged by their insurance company with no deductibles. The OCIP Administrator can help with unusual situations where such manual rates may not be readily available to the contractor. |

We respectfully request that you consider a material substitution away from the acid stain. The specified stain calls for the surface to be acid etched, followed by water rinsing to completely remove acid material. The water would all have to be captured and disposed of. We strongly suggest that you do not use an acid etch process for subject project. Acid washing is normally limited to floor projects. The process of acid cleaning overhead is tenuous at best. Workers would be at risk of serious injury. The ability of the acid etching to actually work properly is questionable. For the acid process to do its job overhead, the surface would need to remain wet long enough for the acid to actually etch the surface. The acid solution could work it’s self into the subsurface through the natural pores. The acid would not be easily removed by water rinsing. The remaining acid in the substrate could than start to attack the substrate over time, possibly making the surface unstable. Finally, the acid base material that is specified is recommended only in well -ventilated or open areas. The use of the acid stain in the tunnel could be problematic for all personnel. The look you wish to achieve can be obtained by using water based stain. We recommend the use of Series 617 Conformal Stain WB. This product can be used on all vertical, above grade concrete, precast, GFRC, exposed aggregate, stucco, terra cotta, brick, and block masonry. The substrate only needs to be clean and dry prior to application. The substrate should be cleaned to remove dirt and other contaminants by whatever means feasible. The Conformal Stain Series 617 has excellent moisture vapor transmissions, meaning it allows moisture to pass through the substrate. |

Refer to SECTION 10-7.402, "Overhead Coiling Doors". Please clarify the need for Sectional roll-up doors as specified or go with an alternate door type, i.e. Overhead Coiling Door. The basis for this question is that the sectional door as specified has over 200 moving parts (i.e. rollers, hinges, track & exposed tension springs & retainers, wall & components fasteners) that cannot be hot-dipped galvanized, leading to accelerated rust problems that will lead to early disrepair of the doors well before even the warranty period is over. We recommend using an overhead insulated coiling door with the slat type curtain in aluminum, nylon endlocks, hood & bottom bar in aluminum, hot-dipped galvanize end brackets, and due to the large sizes, stainless steel guide rails.
