Arm's length rental or lease transactions are those in which the firm involved in the rental or lease of such equipment is not associated with, owned by, have common management, directorship, facilities, and/or stockholders with the firm renting the equipment. Submittal by a Contractor of a rental or lease invoice from the lessor will be prima facie proof of compliance with the above.

Except as noted herein below, this equipment hourly rate plus the estimated operating cost per hour from the Cost Reference Guide will be paid for each hour the equipment actually performs work. Daily records listing the equipment units and their respective operators, identification code, and actual usage, as certified at the end of each workday (or work shift if the work is being performed in multiple work shift sequence) by the Inspector shall be the record upon which actual equipment use shall be based. For multiple shift work sequences, the ENCINO-TARZANA BRANCH LIBRARY GENERAL CONDITIONS PAGE-26 allowable equipment rate shall not exceed the hourly depreciation and operating costs listed in the Cost Reference Guide, for second or third shifts. b. Equipment necessary to be on the site to complete the Work, but not in actual use, shall not exceed fifty percent (50%) of the ownership hourly rate set forth in the Cost Reference Guide, provided that its presence and necessity on the site has been documented by the Inspector, and further provided that the equipment was idled solely by actions of the City. Idle equipment time will only be paid as a function of delays specifically directed or caused by the City's actions. In no event shall the idle time claimed in a day for a particular piece of equipment exceed the normal work schedule established for the project (usually eight (8) hours per day or forty (40) hours per week, and excluding Saturdays, Sundays, and Holidays). For multiple shift work sequences, the allowable idle equipment rate shall not exceed fifty percent (50%) of the hourly depreciation cost listed in the Cost Reference Guide, for second or third shifts. 3.

Underground man-made structures which could not reasonably have been discovered by the Contractor during the period of advertising for bids. 3. Existing fill, unstable soil, or soil that has been disturbed through no fault of the Contractor, any of which requires removal and replacement, compaction, or additional concrete and backfilling. 4. Unknown physical conditions at the job-site of an unusual nature, differing materially from those ordinarily encountered and generally recognized as inherent in the work of the character provided in this Contract. 5.

(c) If the work of the Contract is suspended or delayed by an act of the City, or by failure of the City to furnish required information or if the critical path is affected by the suspension and the Contractor thereby incurs expenses or sustains losses which could not have been avoided by the judicious handling of forces and equipment, and if by a diligent prosecution of the Work, Contractor could not have completed the work before such suspension, the Contractor will be paid such amount as the Board may find to be fair and reasonable compensation for such part of the Contractor's actual loss as was unavoidable and could not have been reduced. In no case shall any compensation be made to cover any loss other than actual cash, paid for wages, rental of equipment, and materials used in protection of the Work, all of which must be supported by satisfactory written evidence. Such wages shall not include the wages or salary of any individual not necessary to the protection of the project. The Contractor shall not be entitled to mark-up of overhead or profit on damages or extended duration. DEFAULT - SUBLETTING - INSURANCE SECTION 41 - SUSPENSION OF CONTRACT (a) If the Contractor should be adjudged bankrupt or if Contractor should make a general assignment for the benefit of his creditors or if a receiver should be appointed on account of insolvency, then in any such case the Board shall have the power to suspend the operations of the Contract. (b) Should the Contractor fail to begin Work within the time required in such a manner as to ensure full compliance with the Contract within the time limit or if the Work to be done under this Contract be abandoned by the Contractor or if at any time the City Engineer is of the opinion that the said Work is unnecessarily or unreasonably delayed or that said Contractor is willfully violating any of the terms of the Contract or is not executing the Contract in good faith or is not following the instructions of the City Engineer as to additional force necessary in the opinion of the City for its completion within the required time or if at any time the Contractor is not properly carrying out the provisions of the Contract in their true intent and meaning, then in any such case, notice thereof in writing will be served upon the Contractor.

Any excess of costs arising there from over and above the Contract price will be charged against the Contractor and his sureties, who will be liable therefore. (d) In the event of such suspension, all moneys due the Contractor or retained under the terms of the Contract shall be forfeited to the City; but such forfeiture will not release the Contractor or Contractor's sureties from liability for failure to fulfill the Contract. The Contractor and Contractor's sureties will be credited with the amount of money so forfeited toward any excess of cost over and above the Contract price arising from the suspension of the operations of the Contract and the completion of the Work by the City, as above provided, and the Contractor will be so credited with any surplus remaining after all just claims for such completion have been paid. (e) In lieu of the exercise of the authority hereinabove given, to employ workers, purchase tools and materials, and complete the Work, the City reserves the right and option instead thereof, to annul and cancel the Contract and to relet the Work or any part thereof, and said Contractor shall not be entitled to any claim for damages on account of such annulment nor shall such annulment affect the right of the City to recover damages which may arise from such failure on the part of the Contractor, to fulfill the terms of the Contract. And in case of such annulment, all moneys due the Contractor, or retained under the terms of the Contract, shall be forfeited to the City; but such forfeiture shall not release the Contractor or Contractor's sureties from liability for failure to fulfill the Contract; and the Contractor and Contractor's sureties shall be credited with the amount of moneys so forfeited toward any greater sum they may become liable for to the City on account of the default of the Contractor. (f) In determination of the question whether there has been such non-compliance with the Contract as to warrant the suspension or annulment thereof, a hearing shall be held before the Board and the decision of the Board will be binding on both parties.

(b) Upon receipt from the Contractor of the names of proposed Subcontractors and Subsubcontractors, the City Engineer will investigate the record, ability and capacity of each, and proof of qualifications and references, and will issue written approval if found to be in the best interest of the City.

Predicated upon the results of the City Engineer's review of monthly submissions of updated Network Diagrams and Reports, and/or the joint City/Contractor review in any given month, the Contractor may be required to revise the Contractor's Construction Schedule. Conditions under which a revision will be made are as follows: a. When a delay in completion of any work items or sequence of work items results in an indicated extension of the project completion or interim milestone dates detailed herein by 30 calendar days. b. When delays in submittals or deliveries or work stoppages are encountered which make replanning or rescheduling of the work necessary. c. When the schedule does not represent the actual prosecution and progress of the project. All revisions and additions to the Contractor's Construction Schedule are subject to the review of the City. DELAYS AND RECOVERY A. If at any time during the project, the Contractor fails to complete any activity by its latest scheduled completion date, the Contractor shall, within five (5) working calendar days, submit to the City, a written statement as to how and when Contractor will reorganize the work force to return to the current Contractor's Construction Schedule. B. Whenever it becomes apparent from the current monthly progress evaluation and updated schedule data that any milestone date(s) and/or Contract completion date will not be met; the Contractor shall take some or all of the following actions: 1. Increase construction manpower in such quantities and crafts as shall substantially eliminate the backlog of work and meet the current Contract completion date. LIBRARY BOND PROGRAM ENCINO-TARZANA BRANCH LIBRARY PROGRESS SCHEDULE AND REPORTS 01311-9 2. Increase the number of working hours per shift, shifts per workday, workdays per work week, or the amount of construction equipment, or any combination of the foregoing sufficient to substantially eliminate the backlog of work. 3. Reschedule work items to achieve concurrence of accomplishment or; NOTE: The City may elect to withhold progress payments until the Contractor's progress indicates that the Milestone date(s) and/or completion will be met. C. 1.12 Under no circumstances will the addition of equipment or construction forces, increasing the work hours or any other method, manner, or procedure to return to the contractually required completion date be considered justification for a Change Order or treated as an acceleration. SCHEDULE TIME EXTENSIONS A. When Change Orders or delays are experienced by the Contractor and a time extension is requested, the Contractor shall submit to the City Engineer, a written Time Impact Analysis illustrating the influence of each change or delay on the current Contract schedule completion date utilizing the approved current Record Schedule. Each Time Impact Analysis shall include a Fragment demonstrating how the Contractor proposes to incorporate the Change Order or delay into the current Record Schedule. A Fragment is defined as a sequence of new and/or activity revisions that are proposed to be added to the approved Baseline Detailed Project Schedule or Current Record in effect at the time the change or delay is encountered to demonstrate the influence of the delay and the method for incorporating the delay and its impact into the schedule as they are encountered. B. Each Time Impact Analysis shall demonstrate the estimated time impact based on the events of the delay, the date of the Field Order, Change Order or the Unilateral Change Order was given to the Contractor, the status of construction at that point in time and the event time computation of all activities affected by the change or delay. The event times used in the analysis shall be those included in the latest update of the Current Record Schedule, in effect at the time the change or delay was encountered. C. Time extensions will be granted only to the extent that equitable time adjustments for the activity or activities affected exceed the total or remaining float along the critical path of activities at the time of actual delay, or at the time the Field Order, the Change Order, and the Unilateral Change Order was issued. Float or slack time is not for the exclusive use or benefit of the City Engineer or the Contractor but is an expiring resource available to all parties as needed to meet Contract milestones and the Contract completion date. Time extensions shall not be granted nor delay damages paid until: 1. A delay occurs which is beyond the control and without the fault or negligence of the Contractor and its Subcontractor or Suppliers, at any tier; and, 2. Which extends actual performance of the work beyond the applicable current Contract completion date and the most recent date predicted for completion of the project on the approved schedule update current as of the time of the LIBRARY BOND PROGRAM ENCINO-TARZANA BRANCH LIBRARY PROGRESS SCHEDULE AND REPORTS 01311-10 delay or as of the time of issuance of the Field Order, the Change Order, or the Unilateral Change Order. 1.13 1.14 D. Each Time Impact Analysis shall be submitted in two (2) copies, within ten (10) days after the delay occurs or issuance of the Field Order, Change Order or Unilateral Change Order, in accordance with Section 15 - TIME FOR COMMENCING AND COMPLETING WORK of the General Conditions. If the Contractor does not submit a Time Impact Analysis for a specific Change Order or delay within the specified period of time, the Contractor shall be deemed to have irrevocably waived any rights to additional time and cost. E. Since float time within the Detailed Project Schedule and the Record Schedule is jointly owned, it is acknowledged and agreed by the Contractor that City caused delays on the project may be offset by City caused time savings (including, but not limited to: critical path submittals returned in less time than allowed for in the Contract, approval of substitution requests, which results in a saving of time along the critical path for the Contractor, etc.). In such an event, the Contractor shall not be entitled to receive an extension of time or delay damages until City caused time savings are exceeded and the Contract completion date also exceeded. F. Approval or rejection of each Time Impact Analysis by the City Engineer shall be made within [fifteen (15) days] after receipt of each Time Impact Analysis, unless subsequent meetings and negotiations are necessary. Upon approval, a copy of a Time Impact Analysis signed by the City Engineer shall be returned to the Contractor for incorporation into the schedule. G. Upon mutual agreement by both parties, fragnets illustrating the influence of Change Orders and delays shall be incorporated into the Detailed Project Schedule or Record Schedule during the first update after agreement is reached. COST LOADING A. In addition to the above network requirements, the Contractor shall furnish cost estimates for each activity which, cumulatively equal the total Contract cost. Mobilization may be shown separately however, other costs i.e. profit, insurance and bond shall be prorated throughout all activities. The cost (loading) allocation shall be included in the review of each application for progress payment. The approval of cost loading or schedule of payment values does not represent approval of true cost of each item. The schedule of payment value shall not be used in Change Order. Contractor shall submit detail estimate for each proposed Change Order. B. The cost loading shall be based upon the Contractor's Construction Schedule and shall equal in total, the Contractor's bid price plus Change Order. C. The Contractor, at the pre-construction conference, shall explain in detail the procedure to be used to develop the schedule cost loading. This procedure is subject to review by the City. Failure to submit an acceptable schedule cost loading shall be considered cause for withholding any progress payments due or that may become due under this Contract. MANPOWER A. The Contractor shall submit with the initial Contractor's Construction Schedule a LIBRARY BOND PROGRAM ENCINO-TARZANA BRANCH LIBRARY PROGRESS SCHEDULE AND REPORTS 01311-11 histogram depicting total project craft manpower and that for each of his principal Subcontractors.

Caustic paste application and use shall be in accordance with manufacturer’s instruction for each product. Prior to beginning the application, all accumulated dust, dirt, and visible oil and grease shall be removed with a five percent non-phosphate and water solution or other equally effective cleaning agent. When a caustic stripping agent is used as the abatement agent, the Abatement Subcontractor shall provide and ensure the use of the following items: - Full-body coveralls with hood impervious to caustic substances; - Gloves impervious to caustic substances; - Glove extenders; - Face shield; - Appropriate boot or shoe covers; - An eyewash station; - A suitable and unrestricted wash area in the event of inadvertent exposure. a. Paint Removal - A caustic stripping agent may require multiple applications, depending on a variety of circumstances. When this type of material is used, care should be taken to avoid drying of the agent. It may become necessary to lightly mist over area with water to keep it moist. Surfaces that come in contact with the stripping agents used in this methodology during washing or neutralizing shall be completely cleaned before the waste dries. (1) Each worker, in order to be allowed in the work area, must have received specific instructions on the procedures to remove material that inadvertently comes in contact with skin, and eyewashing procedures, together with information on the nature of the danger. This can be accomplished by general safety meetings that are regularly scheduled and with a "right- to- know" booklet that is in a location that is known to all persons and is readily accessible. (2) In addition to standardized work area preparation, to protect surrounding areas, polyethylene sheeting shall be placed flush to the surrounding walls for a firm seal to avoid leakage of waste below the polyethylene sheeting, and the joint shall be caulked. The Abatement Contractor may place absorbent pads or material below the surface being abated and/ or place waterproof duct tape on the surface adjacent to that being abated, to prevent damage to the adjacent wall or floor surface. The Abatement Subcontractor is responsible for repairing any adjacent surfaces harmed by the chemical removal process. This includes contamination of these surfaces by chemical residue. LIBRARY BOND PROGRAM ENCINO-TARZANA BRANCH LIBRARY LEAD-BASE PAINT ABATEMENT (DEMOLISHED BUILDING) 02052-27 2. (3) A dwell time may be a specified by the manufacturer. The Contractor shall run a series of test patches to determine the optimal amount of time for the chemical to work on a particular component. (4) Removal of the caustic stripping agent after dwell time shall be performed by scraping the waste off the substrate onto the paper, using a metal scraper. Application process shall be repeated if, in the opinion of the Consultant, complete removal of the paint is not attained. At no time shall dry scraping be used. (5) Once removal of paint from the abated surface is complete, cleanup procedures shall then follow and include wash- down of the surface and neutralization. (6) Once the neutralizing process is complete, the surface shall undergo normal clean- up procedures of HEPA vacuuming, wet wash and repeated HEPA vacuuming. (7) All worker protection equipment as specified shall be left within the work area during all phases of the work. This equipment may be transferred between work areas using double six (6) mil polyethylene bags to prevent contamination of clean areas. (8) All accumulated debris resulting from removal of caustic paste shall be treated as hazardous and shall be properly stored and disposed of according to EPA, DOT, and all other applicable federal, state, and local regulations. (9) Any wood flooring contaminated by the absorption of lead caustic shall be replaced by the Abatement Contractor at his/ her expense. Application and Removal a. Spray or hand trowel paste according to manufacturer’s specifications (no less than -" thick). The caustic stripping agent should be applied with recommended special spray equipment approved by the manufacturer to ensure proper application of product, if spray application is used. (1) b. During spray application no more than two workers (one person applying and one helper) shall be allowed in the work area. Security of work area is absolutely essential. Never remove material with personnel below, or in a manner that would allow caustic to fall on, splatter or contact personnel in the vicinity of the removal. - Minimize the fall distance of the paste/ paint. LIBRARY BOND PROGRAM ENCINO-TARZANA BRANCH LIBRARY LEAD-BASE PAINT ABATEMENT (DEMOLISHED BUILDING) 02052-28 3. 4. 3.09 c. Work area shall be properly heated so as to meet temperature requirements outlined in the manufacturerÆs specifications. Heating procedures shall be subject to the approval of the Consultant and City, and shall be supplied by the G. C. d. Abatement Contractor shall make certain that during the application, dwell time and removal of caustic paste, the work area is secured. Clean Up a. Collect caustic paste cloth with paste/ paint along with remaining residue and put into six (6) mil polyethylene bags and dispose of in compliance with all regulations and specifications. b. Spray surface lightly with water spray. Then with a nylon scrub brush, agitate surface to loosen all residue. Thoroughly scrub surface, being sure to get all crevices, grooves, cracks, etc. c. Lightly spray clean water on surface, removing remaining residue. The use of a wet vacuum to assist in the clean- up is suggested. Make certain that entire surface is clean of any paint/ paste residue. d. Treat residue (paste, paper, water, etc.) as hazardous waste until results of TCLP and TTLC tests are available. Disposal will be dependent upon these results. Neutralization a. Apply caustic stripping agent neutralizer in accordance with manufacturer’s recommendations. Wash neutralizer off with clean water, per manufacturer’s recommendations. b. Apply second application of caustic stripping agent neutralizer if needed and allow to dry. After one to three (1- 3) hours, wash neutralizer off with clean water and allow surface to dry completely. c. Abatement Contractor should use pH paper to determine if neutralization is adequate. A dry surface showing a pH of between 6 and 8 after the proper drying out period, is ready to be recoated. A pH over 8 should be treated to another application of neutralizer and left to dry before retesting. It is most important that the surface properly dry out before recoating. DAILY CLEANUP At the completion of each workday, the Abatement Contractor shall clean the inside of the work area. At a minimum, the following procedures shall be adhered to: A. Cleaning 1. End of Day Cleaning. Thirty (30) minutes or more if necessary prior to the end of each work day, the lead work area must be cleaned of all debris.
