1. A method for forming a concrete member comprising:
a) assembling a first concrete form having first and second ends;
b) assembling a first tendon for a first concrete section, the first tendon including a first anchor, a second anchor, and a first tension member affixed to the first anchor and the second anchor;
c) affixing a connector anchor to the first anchor;
d) affixing the first anchor to the first concrete form first end and affixing the second anchor to the first concrete form second end;
e) pouring concrete into the first concrete form so as to form a first concrete section in which the first anchor and the second anchor are embedded;
f) removing at least the first concrete form first end from the first concrete section;
g) assembling a second tendon for a second concrete section, the second tendon including a coupler, a third anchor, and a second tension member affixed to the coupler and the third anchor, the coupler including a coupler body and a connector, wherein the coupler body is disposed in the connector and the connector is mechanically coupled to the connector anchor,
h) affixing the third anchor to a second concrete form; i) pouring concrete into the second concrete form so as to form a second concrete section which is adjacent to the first concrete section and in which the coupler and the third anchor are embedded;
j) stressing the first tendon at the first anchor; and
k) stressing the second tendon at the third anchor; wherein step g) is carried out before step j).
