The preconstruction and construction services are generally described below. Subcontracts including Plumbing, Fire Protection, HVAC, and Electrical trades will be awarded by the DB to prequalified vendors using a competitive process. The parties will engage in an "open book" pricing method in which all subcontracted work shall be based upon competitive pricing that will be reviewed by the Contracting Authority and the Owner, the Criteria A/E and the DB. The Contracting Authority and/or Owner shall have access to all books, records, documents and other data in the DB's possession related to itself, its subcontractors and material suppliers pertaining to bidding, pricing or performance of the Agreement. Preconstruction Services: The DB will work cooperatively with the Contracting Authority and/or Owner, Criteria A/E and Project Team, and will provide, among other services, schedule development, estimate development, program verification, schematic design, design development, Guaranteed Maximum Price (“GMP”) proposal, subcontractor prequalification and bidding, construction documents preparation, constructability review, permits, budgeting, value engineering, and preconstruction planning throughout the preconstruction stages. When the drawings and specifications are at a stage of completion specified in the Agreement, such partially completed documents (the “Basis Documents”) shall be provided to the DB, together with the Architect/Engineer of Record’s (“AOR”) detailed listing of any incomplete design elements and the AOR’s statement of intended scope with respect to such incomplete elements (the "Design Intent Statement"). Contingent upon the Contracting Authority’s approval of the GMP, the parties will enter into an amendment to the Agreement establishing the Contract Sum (“GMP Amendment”). If the proposed Contract Sum exceeds the Project Budget established for construction, then the Contracting Authority may terminate the agreement with the DB and seek proposals from other firms for completion of the Project. Construction Services: The DB shall construct the Project pursuant to the construction documents and in accordance with the schedule requirements. The DB shall hold all subcontracts and shall be fully responsible for the means and methods of construction, weekly progress meetings, testing and inspections, project safety, project completion within the schedule agreed upon in the preconstruction phase, compliance with all applicable laws and regulations including monitoring compliance with all EDGE, equal employment, and prevailing wage requirements, and submitting monthly reports of these activities to the Contracting Authority. All subcontracts shall be on the subcontract form prescribed by OAC Section 153:1- 03-02. The Contracting Authority reserves the right to approve DB’s selection of subcontractors and any supplemental terms to the subcontract form.
