The construction of gabion structures shall be in accordance with the specifications and in close conformity with the lines and grades shown on the construction plans and cross-sections The base, end and sides of agabion basket are to be of single unit construction or one edge of these members connected to the base section of the unit in sucha manner that strength and flexibility at that point of connection is at least equal to that of the mesh. Where the length of the gabion basket exceeds its horizontal width, the gabion basket is to be equally divided by diaphragms of the same mesh and gauge as the body of thegabion, into cells whose length does not exceed the horizontal width The gabion basket shall be furnished with necessary diaphragms, secured in proper position on the base section in such a manner that no additional tying at this junction is necessary.
