Specifications include, but are not limited to: a. The Construction Task Catalog® issued with this Solicitation will be in effect for the first six (6) months of this contract. b. For each subsequent six (6) month period, a new Construction Task Catalog® will be furnished. The new Construction Task Catalog® will be effective for the six (6)month period following the date of issuance and all previously issued Construction Task Catalogs® will become invalid. Each Construction Task Catalog® shall only apply to Job Orders issued after the effective date of that specific Construction Task Catalog® and shall have no impact on Job Orders issued prior to the effective date of that specific Construction Task Catalog®. c. The contractor will be issued the new Construction Task Catalog® for review and acceptance prior to accepting new work. The Contractor shall use the Construction Task Catalog® in effect on the date that the Job Order is issued. However, the Contractor cannot delay the issuance of a Job Order to take advantage of a scheduled update of the Construction Task Catalog®. In that event, the Contractor shall use the Construction Task Catalog® that would have been in effect without the delay.d. Material price spike adjustment: For the purpose of this clause, a “major spike” is defined as a spike in a specific material cost of more than 25% above what the cost of that material was on the date the Construction Task Catalog® was issued.1. In the event a major spike occurs in a specific material cost, the Contractor may submit a request for a price modification to a Unit Price or individual Job Order. In order to initiate such a request, the Contractor shall,a) identify the specific material that has experienced a major spike, b) identify Pre-priced Task(s) or Job Orders that require the material experiencing a major spike, and c) demonstrate that the spike exists by submitting a minimum of three quotes on material supplier letterhead to show that the current price meets the “major spike” definition above.2. HDOE, after review of a request, may elect to adjust the Unit Price or Job Order by considering it a NPP item. The adjustment will be for the difference between the material cost at the time the Construction Task Catalog® was issued times the quantity stated in the Job Order. The adjustment will not include any other markup, and the NPP adjustment factor will not apply. 3. HDOE at its option may also determine that a drastic decrease in a material cost warrants the same NPP adjustment downward in the Unit Price or a Job Order
