1. A method for using an intermediate anchor assembly, comprising:
a) providing a first concrete form assembly, the first concrete form assembly including a first concrete form, a first anchor affixed to the first concrete form, and a tension member extending through the first concrete form and the first anchor;
b) installing an intermediate anchor assembly on the tension member, the intermediate anchor assembly comprising:
an encapsulated anchor having a front encapsulation extension and a rear encapsulation extension;
a cap, the cap having an outer surface;
a front tube having a proximal end, a distal end, an outer surface, and an inside diameter that is greater than the outer diameter of the tension member;
a front adapter having a proximal end and a distal end,
a rear tube having a proximal end, a distal end, an outer surface, and an inside diameter that is greater than the outer diameter of the tension member;
a rear adapter having a proximal end and a distal end;
c) affixing the encapsulated anchor to the first concrete form;
d) coupling the rear tube to the rear adapter, coupling the rear adapter to the rear encapsulation extension, and inserting a split seal between the tension member and the distal end of the rear tube;
e) placing concrete in the first concrete form so as to embed the first anchor and the encapsulated anchor in a first concrete pour;
f) removing the first concrete form from the first concrete pour;
g) inserting wedges into the encapsulated anchor, coupling the cap to the front encapsulation extension, coupling the front adapter to the cap, coupling the front tube to the front adapter, and inserting a second split seal between the tension member and the distal end of the front tube;
h) providing a second concrete form assembly adjacent to the first concrete pour; the second concrete form assembly including a second concrete form and a third anchor affixed to the second concrete form, wherein the tension member extends through the third anchor and the second concrete form;
i) placing concrete in the second concrete form so as to embed the cap, front adapter, front tube, second split seal and third anchor in a second concrete pour; characterized in that the first anchor is a stressing-end anchor, further including stressing the tension member in the first concrete pour after step i).
