9月20日，随着“奋进号”盾构机破土而出抵达三好街站接收井，公司承建的沈阳地铁三号线12标方型广场站-三好街站区间右线顺利贯通，标志着该区间实现双线贯通，项目正式进入附属工程施工阶段。
沈阳地铁三号线方三区间右线全长816米，最小转弯半径450米，纵断采用“V”字坡，最大坡度28‰。盾构机掘进过程侧穿辽宁省规划院、南湖大厦、人行天桥等多个建构筑物，并近距离下穿南运河和地下综合管廊等重大风险源。
为确保盾构机顺利掘进接收，项目部提前筹划，周密部署，狠抓过程，强化细节，多次组织召开方案研讨会和专家论证会，充分严判预控风险因素，扎实开展盾构平移桌面推演，不断完善安全保证措施和应急处置预案，适时开展针对性应急演练，确保施工全过程可控。同时，严格落实高危工序领导带班制度，严控管片拼装、同步注浆和二次注浆等关键环节工序质量，加强过程复测和监控量测，利用信息化平台全面盯控盾构掘进参数和姿态，及时进行技术分析和实时调整，确保盾构机安全平稳有序推进。
