6.3.4 A copy of the Schedule shall be maintained at the job site and shall be updated (by

CONTRACTOR) as required to reflect any significant changes in the Sequence Of Work, completion times and/or extra work.

6.4 EXTRA AND UNIT PRICE WORK

6.4.1 It is recognized that the original scope of repair work might have to be revised as a result of conditions not fully apparent or accessible during the ENGINEER'S inspection.

6.4.2 Part T-2, STEEL REPAIRS, list several "suspect" areas which may require repair and/or replacement - dependent on the degree of structural damage caused by corrosion. The

CONTRACTOR’S BASE BID scope of work shall include blast cleaning these areas to allow access for inspection by the ENGINEER.

6.4.3 It is the intent of these CONTRACT DOCUMENTS that any required changes be addressed by all parties in a timely manner and completed quickly so as to not disrupt the PROJECT

REPAIRS, and on the PROPOSAL. The CONTRACTOR'S prices quoted on the PROPOSAL for Miscellaneous Welding and unit price work which, in the opinion of the ENGINEER, is excessively inflated over and above standard industry labor/equipment rates shall be grounds for disqualification of a BID.

General Conditions. Extra work performed by the CONTRACTOR which is not authorized in writing by the ENGINEER (and approved by the OWNER) shall not be allowed.

6.5 ENVIRONMENTAL PROTECTION

6.5.1 CONTRACTOR must be aware that the removal of the existing lead, chromium, and cadmium contained exterior paint system by abrasive blasting, the collection of blast debris and the possible on-site waste treatment are "environmentally sensitive" operations and subject to strict

State and Federal environmental regulations.

Subtitle D landfill. This work shall be included in the CONTRACTOR'S BASE BID scope of work.

6.7.3 If the classification indicates a lead content in excess of 5 ppm, then the waste shall be considered as hazardous and treated on-site by a qualified waste treatment SUB-

CONTRACTOR employing the best available technology in accordance with EPA guidelines.

The treated waste shall then be removed and transported to an appropriately licensed waste storage facility. The cost and additional completion time for the treatment and disposal of all hazardous waste, if required, shall be handled as an item of work as provided for on the

PROPOSAL.

6.7.4 The CONTRACTOR shall submit all transport manifests, test reports, chain of custodies, etc. to the OWNER and ENGINEER for all debris removed from the site.

6.8 WORK SCHEDULE AND TIME OF COMPLETION

6.8.1 The job site shall be made available to the CONTRACTOR for his work seven (7) days a week. The CONTRACTOR shall determine his own work schedule.

6.8.2 The work provided for in these CONTRACT DOCUMENTS shall be completed in the calendar day time stated on the PROPOSAL. A "calendar day" shall consist of 24 hours and measured from midnight to the next midnight.

6.8.3 Failure to complete the PROJECT on time shall result in the application of liquidated damages against the CONTRACTOR as defined herein.

6.8.4 CONTRACTOR must take into account their expected down-times due to typical weather conditions at the time the work is performed, equipment breakdowns, labor shortages, scheduling conflicts, material delivery delays, recognized holidays or any other incidents or conditions which can be expected to occur on a project of this size and magnitude. The

CONTRACTOR'S failure to properly staff the job, failure to manage the work or failure to allow for usual weather delays shall not entitle the CONTRACTOR to additional time.

6.8.5 No extensions of contract time due to weather delays shall be considered by the OWNER unless the OWNER is satisfied that the weather was significantly severe and unusual for long periods of time in which the work is performed and that the overall PROJECT completion time was, in fact, truly impacted by the severe and unusual weather. The burden to prove "severe" and "unusual" weather is upon the CONTRACTOR.
