Concealed or Unknown Conditions If the Contractor encounters conditions at the site that are (1) subsurface or otherwise concealed physical conditions that differ materially from those indicated in the Contract Documents or (2) unknown physical conditions of an unusual nature, that differ materially from those ordinarily found to exist and generally recognized as inherent in construction activities of the character provided for in the Contract Documents, the Contractor shall promptly provide notice to the Owner and the Architect before conditions are disturbed and in no event later than twenty-one (21) calendar days after first observance of the conditions. The Owner will promptly investigate such conditions and, if the Owner determines that they differ materially and cause an increase or decrease in the Contractor’s cost of, or time required for, performance of any part of the Work, will authorize an equitable adjustment in the Contract Sum or Contract Time, or both. If the Owner determines that the conditions at the site are not materially different from those indicated in the Contract Documents and that no change in the terms of the Contract is justified, the Owner shall promptly notify the Contractor in writing, stating the reasons. If the Contractor disputes the Owner’s determination, the Contractor party may assert a Claim as provided in Article 15.
No Hazardous Materials (A) have been disposed of or otherwise released from any Real Property of the Company or any of its Subsidiaries in violation of any Environmental Laws; or (B) are present on, over, beneath, in or upon any Real Property or any portion thereof in quantities that would constitute a violation of any Environmental Laws. No prior use by the Company or any of its Subsidiaries of any Real Property has occurred that violates any Environmental Laws, which violation would have a material adverse effect on the business of the Company or any of its Subsidiaries.
Hazardous Conditions Whenever the Contractor’s operations create a condition hazardous to traffic or to the public, the Contractor shall provide flagmen and furnish, erect and maintain control devices as are necessary to prevent accidents or damage or injury to the public at Contractor’s expense and without cost to the County. The Contractor shall comply with County directives regarding potential hazards. Emergency lights and traffic cones must also be readily available at all times and must be used in any hazardous condition. Emergency traffic cones must be placed in front of and behind vehicles to warn oncoming traffic. Signs, lights, flags, and other warning and safety devices shall conform to the requirements set forth in Chapter 5 of the current traffic manual, Traffic Control for Construction and Maintenance Work Zones, published by the state of California Department of Transportation. The Contractor shall take proper safety and health precautions to protect the Work, the workers, the public, and the property of others. The Contractor shall also be responsible for all materials delivered and Work performed until completion and acceptance of the entire construction Work, except for any completed unit of construction thereof which theretofore may have been accepted.
Contamination The presence in, on or under land, air or water of a substance (whether a solid, liquid, gas, odour, heat, sound, vibration or radiation) at a concentration above the concentration at which the substance is normally present in, on or under land, air or water in the same locality, that presents a risk of Environmental Harm, including harm to human health or any other aspect of the Environment, or could otherwise give rise to a risk of non-compliance with any Statutory Requirement for the protection of the Environment.
Hazardous Material Contractor shall not permit any Hazardous Material (as defined below) to be located, used, incorporated into the Work or brought onto the Job Site in connection with the Work unless (i) absolutely necessary because no alternative is available, (ii) the precise nature and quantity of the Hazardous Material is specified in writing to Owner, (iii) the prior written approval of Owner is obtained, and (iv) Contractor complies with all Laws and prudent business practices concerning the Hazardous Material required. If Contractor encounters any material it reasonably believes to be Hazardous Material, or becomes aware of any incident involving Hazardous Material at the Job Site, Contractor shall immediately stop the Work in the area so affected and shall immediately report the same to Owner. Contractor shall also immediately notify Owner of any notice Contractor receives concerning the presence or use of Hazardous Material at the Job Site. Contractor shall be liable for all on and off-site disposal or transport of Hazardous Material (and shall sign any manifest for the transport or storage of such Hazardous Material), and for any discharge, release, injury to any person, or injury or damage to any property resulting from use of Hazardous Material in the performance of the Work. Contractor shall, at its expense, cause the removal of the Hazardous Material and remedy any associated problems in accordance with applicable Laws and prudent business practices. "Hazardous Material" shall mean (1) any Hazardous Material as defined under the Comprehensive Environmental Response, Compensation and Liability Act of 1980, the Resource Conservation and Recovery Act, or under any applicable state or local Laws, (2) any substance or matter that results in liability to any person or entity from discharge of or exposure to such substance or matter under any statutory or common law theory, (3) pesticides, asbestos, formaldehyde, polychlorinated biphenyl, solvents, petroleum and motor fuel hydrocarbon material, and (4) any other substance or matter that becomes subject to any federal, state or local agency order or requirement for removal, treatment or remedial action. To the extent permitted by Law, and without in any way limiting any other indemnity obligation under this Agreement, Contractor shall indemnify, defend (at Contractor's sole cost and with legal counsel acceptable to Owner) and hold Owner and their respective officers, directors, agents, employees, representatives, shareholders, partners, affiliates, successors and assigns harmless, from and against any and all claims, losses, costs or liabilities arising out of an incurred connection with removing or remediating any Hazardous Materials on or about the Job Site or transported on, to, from or about the Job Site by Contractor. This indemnity shall be effective during and after completion of the Work.
