A telescoping concrete form assembly is provided. The concrete form assembly includes a hollow, first member assembly with an elongated hollow body and a generally planar vertical first sidewall, as well as a second member assembly including an elongated body with a medial portion having an outer cross-sectional shape corresponding to the first body inner cross-sectional shape. The second member assembly is slidably disposed within the first member assembly and is structured to move between a retracted first position, wherein the second member assembly is substantially disposed within the first member assembly, and a second position, wherein the second member assembly extends from the first member assembly. |

1. A concrete form assembly comprising:
a hollow, first member assembly including an elongated body with a first end, a medial portion, a second end, an inner cross-sectional shape and a generally planar vertical first sidewall; a second member assembly including an elongated body with a first end, a medial portion, a second end, said second member medial portion outer cross-sectional shape corresponds to said first body inner cross-sectional shape; wherein said second body is slidably disposed within said first body and structured to move between a retracted first position, wherein said second body is substantially disposed within said first body, and a second position, wherein said second body extends from said first body; a number of utilization assemblies, said utilization assemblies selected from the group consisting of: a longitudinal measuring system, a support rod enclosure disposed with said second body, a level disposed on said first body, an elastic coupling structured to extend between one of said first or second bodies and a support assembly, and a number of handles disposed on said first body; said first body has a generally rectangular cross-section including a second vertical sidewall, an upper sidewall and a lower sidewall; said second body has a generally rectangular cross-section including a first vertical sidewall, a second vertical sidewall, an upper sidewall and a lower sidewall; said first body upper sidewall is substantially planar; said second body upper sidewall is substantially planar; said first body second vertical sidewall includes a key; said second body second vertical sidewall includes a key; and wherein, when said second body is in said first position, said second body key is disposed in said first body key. |
