Bidder___________________________________ Signature:________________________________ Date:________________ Title:_____________________________________ Page 2 of 185 ATTACHMENT 1 RESPONSE TO QUESTIONS ITEM# RFI QUESTIONS ANSWERS The Contract Documents (General Conditions 5.25 and Special Provisions Section 6), require contractor to indemnify the City without any exclusion for the indemnitee’s sole active negligence or sole willful misconduct (See California Civil Code Section 2782(b). Please confirm that the City’s intent is that the Indemnity provisions of the contract comply with applicable Section 5.25 clearly exempts claims “caused by law and please modify the Contract Documents the active negligence, the sole negligence, or the 1 accordingly. willful misconduct of the City.” Please clarify if USL&H Workers Compensation Insurance (US Longshore Insurance) will be a requirement for this project? Please further clarify if landside contractors will be required to Refer to 2-8, CONTRACTOR'S CERTIFCATE 2 carry USL&H Insurance, as this is not typical. REGARDING WORKERS COMPENSATION Are there any geotechnical reports available to review? Do bidders need to provide the See Addendum #3. No, this has been provided by 3 geotechnical engineering services? GHD and paid by the City. Regarding the design-build nature of the floating dock system, the project specifications and drawings show prescriptive design details for the floating dock system. The drawings show specific design details including waler sizing, etc. that will not take into account the float manufacturers standards and own engineering creativity to meet the performance requirements of the floating dock system. In addition, the specification provided contains several differences from the float manufacturer’s standards (wall thickness, etc.). The specifications state that the dock manufacturer is required to submit stamped, signed Design Drawings and Design Calculations sealed by a Professional Engineer for the floating dock system (i.e. Float Designer). Since the floating dock manufacturer is responsible to design the final product, we would like clarification that the drawings and specifications are provided for reference to The bid documents present performance describe performance requirements and the float specifications for the floating docks and are not manufacturer shall be responsible for the final intended to be prescriptive. The dock design and performance of the floating dock manufacturer will be responsible for final design 4 system. Please clarify. and performance of the system. Page 3 of 185184 The engineer of the floating dock system would like to propose an alternate match-cast, post-tensioned robust concrete floating dock system as opposed to the 58’ long x 24’ wide x 5’-6” deep steel berthing dock. Will the berthing dock system be allowed to be constructed of a series of precast, match-cast, EPS foam-filled concrete modules, which are held together using a bonded post-tensioned strands or bars so they create a continuous concrete beam? This technology is exactly what has been constructed on several other projects with a long proven history. This includes most recently, the USS Arizona Memorial Ferry Dock in Pearl Harbor where GHD was the Owner’s Engineer. Will the City accept an alternate concrete match-cast, post- tensioned dock system designed by the dock system engineer, while complying with the design criteria? The match-cast, post-tensioned concrete dock system is a better solution for the following reasons: a. The concrete dock system is an unsinkable structure. The steel platform is hollow, therefore, upon a heavy impact incident, it runs the risk of a hole being punctured into the hollow pontoon and subsequently sinking. b. The concrete dock system does not require the maintenance of a steel platform. The steel platform would need to be removed from the location at unknown intervals for maintenance. The concrete dock system would be a permanent structure equivalent or better to a steel barge with a designed service life of up to 50 years. c. The match-cast, post-tensioned alternate dock system would realize greater longevity and durability when compared to a steel barge system for a lesser cost. By utilizing the alternate dock system, the Contractor would be responsible for the design and construction (without pointing fingers to manufacture a prescriptive design). Match-cast, post-tensioned construction has a long history of successful use worldwide, and is common in the construction of large bridge projects where fatigue resistance and environmental durability are crucial. The post-tensioning elements will be protected from corrosion by filling the PT duct with an appropriate grout or grease product. Concrete shear keys are used to provide continuity and shear transfer at the float joints. This configuration forms a continuous floating structure where the post-tensioning force is sufficient A concrete float would be acceptable provided all to prevent the float joints from opening at the tension performance and service life requirements are face during the design vertical and lateral loading events.
