Written inquiries regarding the IFB may be email to OSBM-DR (Tylor Dockery, Senior Project Manager) at tylor.dockery@osbm.nc.gov up until 5:00 pm on February 9, 2023. OSBM-DR will post an addendum of answers to those inquiries or questions presented at the pre-bid meeting by February 10, 2023. The bid opening has been scheduled from 2:00 pm to 3:00 pm. Bidder attendance at bid opening is not mandatory and all bidders will receive a copy of the bid tabulation. OSBM-DR will make a preliminary statement at the opening that will identify all bidders that submitted timely bids and a statement for each bid as to whether it technically complied with the IFB's instructions. OSBM-DR will issue a bid tabulation to all bidders within one or two business days following the public opening and the tabulation will provide an average price for each bidder, an average price per square foot for the demolitions, or the total lump sum price of each bidder subject. The bid tabulation will also be posted on the North Carolina Interactive Purchasing System's website by the State Construction Office for OSBM-DR. OSBM-DR reserves the unqualified right to reject any and all bids. After the opening of bids, no bid may be withdrawn, except under the provisions set forth in Section 143-129.1 of the North Carolina General Statutes. A bidder's pricing shall remain valid for a period of forty-five (45) days unless otherwise specified in bid or an addendum to the IFB. Should the successful bidder default and fail to execute a contract, the contract may be awarded to the next lowest and responsible bidder, and OSBM-DR reserves the right to seek compensation from the original successful low bidder to cover any increased costs between the two bids. It is a condition of this Contract that the work may be subject to inspection by the local authority having jurisdiction ("AHJ"). OSBM-DR will also conduct quality assurance/quality control ("QA/QC") inspections of the demolition work and final inspection to close out the contract. OSBM-DR will also make inspections to approve progress payments. Contractor shall permit all inspections at the project site during normal working hours and during any time work is in preparation and progress by the AHJ, OSBM-DR, homeowner and/or those persons required by state law to test special work for official approval. The Contractor shall therefore provide safe access to the work at all times for such inspections. OSBM-DR does not expect any changes in the work, but there may be unknown or concealed conditions discovered by Contractor during demolition. Contractor shall provide timely notice of such conditions and submit a request for change order based on the actual net costs of all work at the Project site plus a reasonable markup for overhead and profit that shall not exceed a combined total of 25% of actual costs. OSBM-DR will pay approved change orders in the next scheduled progress payment after the change order work has been completed and accepted by AHJ and/or OSBM-DR. No change order will be allowed for any concealed underground utility if Contractor failed to "Call Before You Dig."
