This new joint detail may be said to constitute the state of the art, insofar as it has been recommended for the above project by the two American consulting firms that have designed the large majority of steel tunnels in the U.S.A.
这种新的接头详图可谓是构成了当今技术的发展现状，有两家美国咨询公司已经推荐上述工程采用这种方式，这两家公司设计了绝大多数在美国的钢壳隧道。
如何翻译出 insofar as 这个连接关系呢？查字典的意思是 “在。。。之内”，“到。。。的程度”
请大家指点一下~
