THE CONDITION OF THIS OBLIGATION IS SUCH, that, if the Contractor, his or its heirs, executors, administrators, successors or assigns, shall in all things stand to and abide by, and well and truly keep and perform the covenants, conditions and agreements in the Contract Documents and any alteration thereof made as therein provided, on its part, to be kept and performed at the time and in the manner therein specified, and in all respects according to their intent and meaning; and shall faithfully fulfill all obligations including, if provided as part of the Contract Documents, the one-year guarantee of all materials and workmanship; and shall indemnify and save harmless the City, its officers and agents, as stipulated in said Contract Documents, then this obligation shall become null and void; otherwise it shall be and remain in full force and effect.

As a condition precedent to the satisfactory completion of the Contract Documents, unless otherwise provided for in the Contract Documents, the guarantee obligation shall hold good for a period of one (1) year after the acceptance of the work by City, during which time if Contractor shall fail to make full, complete, and satisfactory repair and replacements and totally protect the City from loss or damage resulting from or caused by defective materials or faulty workmanship the above obligation in penal sum thereof shall remain in full force and effect.

Contractor shall within five (5) Days of identifying any such delay notify City in writing of causes of delay. City shall ascertain the facts and extent of delay and grant extension of time for completing The Work when, in its judgment, the facts justify such an extension. Time extensions to the Project shall be requested by the Contractor as they occur and without delay. No delay claims shall be permitted unless the event or occurrence delays the completion of the Project beyond the Contract completion date.
d. No Damages for Reasonable Delay. City’s liability to Contractor for delays for which City is responsible shall be limited to only an extension of time unless such delays were unreasonable under the circumstances. In no case shall City be liable for any costs which are borne by the Contractor in the regular course of business, including, but not limited to, home office overhead and other ongoing costs.

Damages caused by unreasonable City delay, including delays caused by items that are the responsibility of City pursuant to Government Code section 4215, shall be based on actual costs only, no proportions or formulas shall be used to calculate any delay damages.

Contractor shall not be entitled to compensation, and the City will not compensate Contractor, for delays which impact early completion.
5) Contractor’s entitlement to an extension of the Contract Time is limited to City-caused extension of the critical path, reduced by the Contractor’s concurrent delays, and established by a proper time impact analysis. No time extension shall be allowed unless, and then only to the extent that, the City-caused delay extends the critical path beyond the previously approved Contract Time.
(a) Contractor shall not be entitled to an adjustment in the Contract Time for delays within the control of Contractor. Delays attributable to and within the control of a subcontractor or supplier shall be deemed to be delays within the control of Contractor.

Contractor must demonstrate that the delay arises from unforeseeable causes beyond the control and without the fault or negligence of both Contractor and any Subcontractors or Suppliers, or any other persons or organizations employed by any of them or for whose acts any of them may be liable, and that such causes in fact lead to performance or completion of the Work, or specified part in question, beyond the corresponding Contract Times, despite Contractor’s reasonable and diligent actions to guard against those effects.
(b) Each request for an extension of Contract Time must include a time impact analysis in CPM format to calculate the impact of the delay event.
7) Contractor’s failure, neglect, or refusal to comply with these requirements, or any portion thereof, shall bar Contractor’s request for extensions of the Contract Time. Such failure, neglect, or refusal prejudices the City’s ability to recognize and mitigate delay, and such failure, neglect, or refusal prevent the timely analysis of requests for extensions of Contract Time, and whether such extensions may be warranted. Contractor hereby waives all rights to extensions of Contract Time due to delays or accelerations that result from or occur during periods of time for which Contractor fails, neglects, or refuses to fully comply with the requirements of this Article. 8) Force Majeure: The time period(s) specified in the Schedule of Performance for performance of the services rendered pursuant to this Agreement shall be extended because of any delays due to unforeseeable causes beyond the control and without the fault or negligence of the Contractor, including, but not restricted to, Acts of God or of the public enemy, unusually severe weather, fires, earthquakes, floods, epidemics, pandemics, quarantine restrictions, riots, strikes, freight embargoes, wars, litigation, and/or acts of any governmental agency, including the City, if the Contractor shall within ten (10) Days of the commencement of such delay notify the Contract Officer in writing of the causes of the delay. The Contract Officer shall ascertain the facts and the extent of delay, and extend the time for performing the services for the period of the enforced delay when and if in the judgment of the Contract Officer such delay is justified. The Contract Officer's determination shall be final and conclusive upon the parties to this Agreement.

55 SECTION 02311 – SUBGRADE STABILIZATION
02311-1 GENERAL
The section provides specifications for subgrade stabilization and appurtenances which may be used during construction.

Variations of surface, soil moisture, and groundwater conditions will likely occur as a result of changes of precipitation, irrigation, runoff, land use, and other factors. The actual elevation or depth to groundwater at sites may fluctuate. It is the Contractors responsibility to control groundwater, where encountered, to provide stable subgrade for pipe laying, trenching and earth fill operations.

02311-2 SUBGRADE STABILIZATION
Unstable or yielding subgrade conditions will be encountered at the base of excavations due to the presence of moist soils and/or shallow groundwater.

For those conditions, the bottom of the excavation should be stabilized to provide a subgrade that is firm and unyielding.

The Contractor, after considering input from the Engineer, shall be responsible for design and implementation of subgrade stabilization techniques. Some methods that have previously been used to stabilize yielding subgrade conditions are described below. The actual subgrade stabilization method used could vary from those indicated below depending on the conditions encountered during construction:

A. to 1-1/2-foot-thick layer of 3-inch to 4-inch minus float-rock worked into the soft subgrade soils.

B. Geotextile fabric or geogrid placed on the yielding subgrade and covered with at least 2 feet of crushed rock or processed miscellaneous base (PMB) conforming to the requirements of Section 200-2.5 of the SSPWC and compacted to a minimum of 85 percent relative compaction.

Automatic controls shall conform to and be operated in accordance with the following provisions.

Unless approved otherwise, ski type devices, with a minimum length of 30 feet, shall be used to provide a reference for the grade sensor. Skis shall be constructed and installed in such a manner that a reference to the average elevation of the existing pavement, along the length of ski, is maintained at the sensor point. When placing surfacing adjacent to surfacing previously placed in conformance with these provisions, a joint matching shoe, of adequate size and type to properly sense the grade of the previously placed mat, may be used in lieu of the 30-foot ski.

The ski shall be mounted at a location which will provide an accurate reference for the surfacing being placed. This may require the ski to be mounted ahead of, and inside the outer limits of the screed. Automatic cross slope control may be accomplished by use of a ski and grade sensor on each side of the paving machine.

Automatic screed controls shall be installed in such a manner that the occasional manual adjustments necessary to maintain the attitude of the screed parallel to the underlying pavement are readily accomplished.

Automatic screed controls shall be installed so that with little or no delay, use of the automatic controls can be discontinued and the screed controlled by manual methods.

Should the automatic screed controls fail to operate properly during any day's work, the Contractor may use manual control of the spreading equipment for the remainder of that day, provided the quality of the work conforms to the requirements of Subsection 302-5 of the SSPWC. Should the methods and equipment used for automatic control fail to result in the quality of work required by said Subsection 302-5, the paving operations will be temporarily discontinued, and the Contractor shall make the necessary changes to the equipment, or furnish other equipment conforming to the requirements herein, before paving is resumed.

Where two overlays of different thickness abut at a longitudinal joint, the Contractor shall add to the thinner section to match the thicker lift and provide a smooth transition and uniform cross-fall. Cold milling of ridges or other rises in the new pavement surface may be required by the Engineer to correct these irregularities.
