INITIATING MEDIATED SETTLEMENT CONFERENCES A. Purpose of Mandatory Settlement Conferences. Pursuant to G.S. §143-128(f1) and 143- 135.26(11), these Rules are promulgated to implement a mediated settlement program designed to focus the parties’ attention on settlement rather than on claim preparation and to provide an opportunity for orderly settlement negotiations to take place. Nothing herein is intended to limit or prevent the parties from engaging in settlement procedures voluntarily at any time prior to or during commencement of the dispute resolution process. B. Initiating the Dispute Resolution Process 1. Any party to a County public construction contract (referred to herein generally as the “Contract”) governed by Article 8. Ch. 143 of the General Statutes and identified in G.S. § 143- 128(f1) and who is a party to a dispute arising out of the Contract and the construction process in which the amount in controversy is at least $15,000 may submit a written request to the County for mediation of the dispute. 2. Prior to submission of a written request for mediation to the County, the party requesting mediation should give notice of any and all claims in accordance with their respective contracts, obtain decisions on the claims as required or allowed by their respective contracts, and attempt to resolve the dispute according to the terms and conditions in their respective contracts. The Mediator may adjourn any mediated settlement conference if the Mediator believes, in his or her sole discretion, that the parties have not satisfied all of the terms and conditions of their respective contracts and that doing so will enhance the prospects for a negotiated settlement. C. Condition Precedent to Litigation.

B. Joint Priming: Prime joint substrates where indicated or where recommended by joint sealer manufacturer based on preconstruction joint sealer-substrate tests or prior experience. Apply primer to comply with joint sealer manufacturer's recommendations. Confine primers to areas of joint sealer bond, do not allow spillage or migration onto adjoining surfaces. C. Masking Tape: Use masking tape where required to prevent contact of sealant with adjoining surfaces which otherwise would be permanently stained or damaged by such contact or by cleaning methods required to remove sealant smears. Remove tape immediately after tooling without disturbing joint seal. 3.3 INSTALLATION OF JOINT SEALANTS A. General: Comply with joint sealant manufacturer's printed installation instructions applicable to products and applications indicated, except where more stringent requirements apply. B.

DocuSign Envelope ID: 51195338-6F17-4D2B-B990-4A82329E7F4E OC DSS -Hillsborough Commons Skylight Replacement Smith Sinnett / 2020054 Hillsborough, NC Orange County JOINT SEALANTS 07 92 00 - 6 a. Do not leave gaps between ends of joint fillers. Bond ends of gaskets together with adhesive of "weld" by other means as recommended by manufacturer to ensure continuous watertight and airtight performance. Miter-cut and bond ends at corners unless molded corner units are provided. b. Do not stretch, twist, puncture, or tear joint fillers. c. Remove absorbent joint fillers which have become wet prior to sealant application and replace with dry material. 2. Install bond breaker tape between sealants and joint fillers, compression seals, or back of joints where adhesion of sealant to surfaces at back of joints would result in sealant failure. 3. Install compressible seals serving as sealant backings to comply with requirements indicated above for joint fillers. D. Installation of Sealants: Install sealants by techniques, that result in sealants directly contacting and fully wetting joint substrates, completely filling recesses provided for each joint configuration, and providing uniform cross-sectional shapes and depths relative to joint widths which allow optimum sealant movement capability. 1. For sidewalks, pavements and similar joints sealed with elastomeric sealants and subject to traffic and other abrasion and indentation exposures, fill joints to a depth equal to 75% of joint width, but neither more than 5/8" deep nor less than 3/8" deep. 2. For normal moving joints sealed with elastomeric sealants but not subject to traffic, fill joints to a depth equal to 50% of joint width, but neither more than ½" deep nor less than 1/4" deep. 3. Install fire-rated sealants or sealants used in fire-rated joints or assemblies in a accordance with manufacturer's recommendations and as acceptable to Code authorities to achieve the required rating. E. Tooling of Non-sag Sealants: Immediately after sealant application and prior to time skinning or curing begins, tool sealants to form smooth, uniform beads of configuration indicated, to eliminate air pockets, and to ensure contact and adhesion of sealant with sides of joint. Remove excess sealants from surfaces adjacent to joint. Do not use tooling agents which discolor sealants or adjacent surfaces or are not approved by sealant manufacturer. 1. Provide concave joint configurations per Figure 6A in ASTM C 962, unless otherwise indicated. 3.4 CLEANING A. Clean off excess sealants or sealant smears adjacent to joints as work progresses by methods and with cleaning materials approved by manufacturers of joint sealants and of products in which joints occur. 3.5 PROTECTION A. Protect joint sealants during and after curing period from contact with contaminating substances or from damage resulting from construction operations or other causes so that they are without deterioration or damage at time of Final Acceptance. If, despite such protection, damage or deterioration occurs, cut out and remove damaged or deteriorated joint sealants immediately and reseal joints with new materials to produce joint sealer installations with repaired areas indistinguishable from original work.
