1.0.1 The Specifications are specially established with a view to adapting to the demand of construction of drainage engineering for airfield area of civil airports in China, strengthening the construction management and safety production, improving construction technique level and ensuring engineering quality, economy and rationality, materials conservation and economic benefit promotion.
1.0.2 The Specifications are applicable to the quality standard, inspection frequency and method for construction of drainage engineering for airfield area of newly-built, extended and rebuilt civil airports (including the civil parts of civil and military airports). General airports and heliports may be implemented by reference to the Specifications.
1.0.3 Corresponding technical measures shall be taken for the construction of drainage engineering for airfield area of airports according to design document in combination with local climate, hydrology, geology, tools, equipment etc. so as to ensure engineering quality and construction safety.
1.0.4 New technique, technology, material and equipment which are mature and approved by competent departments shall be actively popularized during construction of drainage engineering.
1.0.5 Quality requirements in the Specifications are established according to practical experience in civil airport construction over the years by reference to the current relevant national standards. The construction of drainage engineering for airfield area of airports shall not only meet the requirements stipulated in the Specifications, but also comply with those specified in relevant current national standards and specifications.
