지침 개정에 따른 경과 조치

이 지침은 발간시점부터 적용하며, 이미 시행중인 설계용

역이나 건설공사에 대하여는 발주기관의 장이 필요하다 인정

하는 경우에는 적용할 수 있습니다.

머 리 말

국도는 국가 간선도로망의 중추적 역할을 수행하며, 지역 간 연결성 강화와 균형 발전을

견인하는 핵심 기반시설입니다. 이에 따라 국도건설사업의 설계 단계는 단순한 도로 선형

결정에 그치지 않고, 기능성·경제성·안전성 등을 종합적으로 고려한 고도화된 기술적 판단을

요구하고 있습니다. 이러한 배경 속에서, 『국도건설공사 설계 실무요령』은 다양한 현장에

맞는 설계 판단을 가능하게하여, 국도 건설사업의 설계 품질을 확보하는데 큰 기여를 해

오고 있습니다.

이번 개정은 「국도 설계업무 매뉴얼」, 「2+1차로 도로설계지침」, 「국도건설 실무 매뉴얼」

등 국도 설계 업무원 관련된 간행물을 설계실무 요령에 흡수·통합한 점에서 그 의의가

큽니다. 이로써 간행물간 중복·상충 문제를 최소화하고 보다 전반적인 국도 설계 업무

전반을 파악하고 수행할 수 있는 실무체계가 마련되었습니다.

이를 통해 본 설계실무 요령은 단순한 설계 안내서의 기능을 넘어, 계획, 설계, 시공

간의 연계성을 담보하는 통합형 지침으로 자리매김할 것입니다. 또한, 앞으로는 개정시

국도건설공사에 대한 전반적인 내용이 검토되어 기준의 정합성이 더욱 높아질 것으로

기대하고 있습니다.

앞으로도 국토교통부는 설계 현장의 목소리를 반영하여 본 실무요령을 지속적으로 개

선해 나갈 예정이며, 본 지침이 국도건설공사의 품질과 효율을 높이는데 실질적인 도움이

되기를 기대합니다.

마지막으로 본 지침을 마련하는데 참여하신 한국도로협회와 한국건설기술연구원 연구진,

자문위원 그리고 국토교통부 관계공무원 여러분의 노고에 깊은 감사를 드립니다.
