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. However, such invoices are not conclusive proof; if questioned, the
burden of proof remains with the Contractor. In no event shall the leased
equipment rate billed to the City be at rates exceeding those prescribed in
the following table:
Payment Category Blue Book Actual Usage
Less than 8 hours Hourly Rate,
8 or more hours but less than 7 days Daily Rate,
7 or more days but less than 30 days Weekly Rate,
30 days or more Monthly Rate.

shall be the basis that the equipment was on and utilized at the project site.
In addition to the leasing rate and the markup negotiated above, equipment
operational costs shall not exceed the estimated hourly operating rate as
set forth in the Blue Book. The hours of operation shall be based upon
actual equipment usage as recorded by the Inspector. For multiple shift
work sequences, the allowable equipment rate shall not exceed fifty percent
(50%) of the base rate, for second or third shifts.
c.
Idle equipment is equipment on site and necessary to perform the work
under the change but not in actual use. Idle equipment time, as
documented by the Inspector, shall be paid at the rate determined above.
Idle time shall include a reasonable time allowance to and from the project
site.
2. Owned and Other Equipment:
a.
Equipment rates for owned equipment or equipment provided in other than
arm's length transactions will not exceed the total hourly cost listed in the
Cost Reference Guide. 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. Equipment Shipment and Set Up Costs: Documented and actual equipment
shipment and set up costs shall be paid for.
4. In the event that a piece of equipment used on a "Change Order" is not listed in
the Blue Book or the CRG, costs may be derived from the AGC Equipment
Ownership Guide, the Associated Equipment Dealers Guide, or the Equipment
Rate Guide published by the U.S. Army Corps of Engineers.
SECTION 39 - UNFORESEEN CONDITIONS

Contractor. This includes, but is not limited to labor strikes or inclement weather.
(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

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. Should
ENCINO-TARZANA BRANCH LIBRARY
GENERAL CONDITIONS
PAGE-28
the Contractor neglect or refuse to provide means for a satisfactory compliance with
the direction of the City Engineer within the time specified in such notices the Board
shall have the power to suspend the operations of the Contract.
(c)
Upon receiving notice of such suspension said Contractor shall discontinue said Work
or such parts of it as the Board may designate. Upon such suspension the Board
may employ other parties to carry on the Contract to completion, employ the
necessary workers, substitute other machinery or materials, purchase the materials
contracted for in such manner as the Board may deem proper, hire such forces and
buy such machinery, tools, appliances, materials, supplies and equipment at the
Contractor's expense, as may be necessary for the proper conduct of the Work and
for the completion thereof. 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.

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)

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.

any payment) or substitute any portion of the Contract without consent of the Board in writing.

submitted.
j. Severability of Interest: Except with respect to the insurance company's limit

affords City. Further, Contractor shall immediately take all reasonable and
available steps to restore such aggregate limits or shall provide other insurance
protection for such aggregate limits, City may at its option, specify a minimum
acceptable aggregate for each line of coverage required.
4. Self-Insurance and Self-Insured Retention: Self-insurance programs and selfinsured retention in insurance policies are subject to separate approval by City

protection from liability and defense of suits as would be afforded by first-dollar
insurance.
5. Modification of Coverage: City reserves the right at any time during the term of
this Agreement to change the amounts and types of insurance required
hereunder by giving Contractor ninety (90) days advance written notice of such
change. If such change should result in substantial additional cost to Contractor,
City agrees to negotiate additional compensation proportional to the increased
benefit to City.

market at reasonable cost as determined by City. Non-availability or nonaffordability must be documented by a letter from Contractor's insurance

required insurance or a self-insurance program during the entire term of this
Agreement shall constitute a material breach of this Agreement under which
the City may immediately suspend or terminate this Agreement or, at its
discretion, procure or renew such insurance to protect City's interests and
pay any and all premiums in connection therewith, and recover all monies so
paid from Contractor.

Failure to submit adequate and accurate content, in the opinion of the City, in the
Contractor's Construction Schedules, or failure to submit on the dates established by
the City will result in cost to the City; therefore, the Contractor will pay the City a
liquidated damage of $400 for the first day the schedule(s) is late or lacks sufficient
adequacy and $200 per day thereafter. This amount shall be subtracted from any
monies due the Contractor.
C.

1.10
The Contractor shall prosecute the work in accordance with the Contractor's
Construction Schedule. Changes made to the Contractor's Construction Schedule for
accomplishing the work shall be subject to review and acceptance by the City
Engineer for conformance to the requirements of this Division.
B.
Upon approval of a Change Order or issuance of Proceed Order with a change, the
approved change shall be reflected in the next schedule submittal by the Contractor or
other schedule update submittal "X" by the City Engineer.
C.
If the Contractor desires to make a change to the Contractor's Construction Schedule,
he shall notify the City Engineer in writing stating the reasons for the change at the
job-site. If the City Engineer considers the change to be of major nature, the City
Engineer may require the Contractor to revise and submit for acceptance, at the
Contractor's sole expense, all or the affected portion of the Detailed Network Diagram
and analysis to show the effect on the entire project. The proposed revision and
analysis shall be submitted to the City Engineer within fifteen (15) days after the City
Engineer notifies the Contractor the revision is of a major nature. A change will be
considered of a major nature if the time estimated to be required for an activity or the
sequence of activities is varied from the original plan to a degree that there is
reasonable doubt that the Contract completion date will be met or if the change
impacts the work of other Contractors at the job-site. Changes to activities having
adequate float shall be considered as minor changes, except that an accumulation of
minor changes may be considered a major change when such changes affect the
Contract completion date. Revisions to the Contractors Construction Schedule shall
not be made in the same submittal as the monthly updates. They must be submitted
separately in a separate Primavera file.
PROGRESS REPORTS
A.
Once each week on a date established by the City Engineer, the Contractor shall
submit a report/schedule listing the activities, started, completed and in progress for
the previous week and the activities scheduled for the succeeding two weeks. This

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

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

REOCCUPANCY CRITERIA
During all stages of the exterior abatements, dwelling units will be reoccupied after final cleanup and
visual inspection completed by the Consultant at the end of each work day. Two sets of postabatement wipe samples analyzed by atomic absorption spectroscopy (AAS) will be collected for
confirmatory purposes. A comparison will be made with preabatement wipe samples collected prior
to abatement. If the two sets of results are not statistically different, occupancy shall be maintained.
However, if a unit is cleared and re- occupied based on the Consultant’s visual inspection and it
then fails to meet the clearance criteria based on the laboratory results, the cost of the cleaning of
the occupants’ household furnishings will be borne by the Abatement Contractor. U.S. HUD
Guidelines for the Evaluation and Control of Lead- Based Paint Hazards in Housing will apply for
lead wipe results.

Where applicable, no excavation shall commence until the Contractor has
demonstrated to the satisfaction of the Consultant or City Engineer that the groundwater level has been
lowered. De-watering and that the soils inside the excavation are in the de-watered condition that was
assumed in the Contractor's shoring design and submittal.
3.3
INSTALLATION
A.
All trench and excavation openings shall be lighted and fenced or barricaded during
nights, weekends, and other times as necessary and meet CAL/OSHA safety requirements.
B.
All shoring shall be installed to the lines and elevations shown on the Contractor's
review working drawings. No component of the shoring shall infringe on the minimum
dimensions of any permanent structure shown in the Contract Drawings.
C.
The excavation shall be staged as shown in the Working Drawings and in such a
manner as to provide a stable system of support at all times.
D.
Should the shoring system utilize steel H-beams, piles, or other similar vertical
supports, driving of said vertical supports will not be permitted in proximity of existing
structures except for the last 4-feet. The vertical supports shall be placed in holes drilled to a
depth of 4-feet above the proposed bottom of pile, except where this procedure is
impracticable. The vertical support may then be driven to the required depth, not to exceed 4feet. During the drilling and driving operations, the Contractor shall take care to avoid damage
to utilities.
At locations where the drilling of such holes is impracticable because of the existence
of obstructions or rocks, running sand, or other adverse condition, and provided said
impracticability is demonstrated to the satisfaction of the Engineer by actual drilling operations
by the Contractor, the Engineer may, upon request of the Contractor, approve the use of means

Measurements shall be referenced from an initial
position of the shoring, as jointly established and agreed upon by the
Contractor and the City Engineer.
Horizontal deflections into the excavation at any
location on the shoring shall be limited to a maximum of 1-inch. If at any time
this deflection exceeds 1-inch, immediate corrective measures shall be taken
by the Contractor to prevent any further deflections.
The Contractor shall stop the excavation work until
corrective measures have been taken and the deflections have been reduced
to acceptable limits as specified.
Monitor adjacent ground and structures on both sides of excavations to verify that no
settlement is occurring or has occurred as a result of the Contractor's construction activities.
3.5
REMOVAL
A.
Shoring shall be removed as necessary under the direction of the City of Los Angeles
Building and Safety inspector and the Soils Engineer to allow backfill to be placed and
compacted. If in the opinion of the Inspector it should not be possible to remove any
components of the shoring without disturbance of damage to adjacent structures, properties, or
facilities, the Contractor shall leave them in place, except for the shoring that is within the
limits of future construction or within 5-feet of the final surface elevations. This upper portion of
the shoring shall be cut and removed from the site. All voids existing behind the shoring which
remains in place shall be backfilled as specified in Section 02200 - EARTHWORK.
B.
Shoring shall be removed as backfilling progresses. Removal shall be conducted in
such a manner so as to avoid any damage to the tunnel structure, adjacent facilities, or to

E.
Horizontal joints shall have full mortar coverage on face shells. Butter head joints well for
the full width of the face shell and shove these joints tightly so that the mortar bonds well
to both concrete block.
CLEANING AND PROTECTING
Remove mortar and grout stains from concrete block surfaces immediately upon their discovery. Clean
exposed concrete block surfaces with one of the specified cleaners used in strict accordance with the
manufacturer's printed instructions. Take all necessary precautions to avoid staining the concrete
block and adjacent surfaces. Cover sills and top course of unfinished work with waterproof coverings
and tie securely in place to prevent its accidental displacement. Dampen (but don't saturate) the
surface of the concrete block masonry with a light fog spray when the atmosphere is excessively dry
and keep it damp for approximately three days to permit the mortar to thoroughly cure.
