This collection contains over two thousand plans of structure designs, renovations, and additions to buildings, mostly in and around Columbus, Georgia. Other unique drawings are also present in the collection, including a bookcase design and cannon ball mounts. A number of surveys and maps have been integrated within the collection. At times this appears to be an odd match, but it was determined to be the best method of storage and tracking of these items so they were included. Most of the works were made under T. Firth Lockwood Jr. and James Joseph Walton Biggers Sr., but several other architects, draftsmen, and surveyors appear and include: Charles F. Hickman, John C. Martin Jr., Roy D. Murphy, Lorin D. Raines, E. Orin Smith, Ross O. Baldwin Jr., Lewis A. Scarbrough, Edward W. Neal, Donald G. Crisp Jr., Hugh McMath, M. J. Blackmon Jr., and others. The dates for the plans range from the 1910s to the 1980s.

The collection is divided into several groups:

Lockwood- These drawings use the original numbering system that starts around 500 and are sequentially numbered. The dates roughly correspond with the number.

Biggers- These drawings use their original numbering system. This collection works with four digit numbers. The first two numbers represent the year while the second two numbers roughly correspond to the order drawn or created.

FB- These are the drawings and surveys relating to Fort Benning.

JB- These drawings are connected with J. J. W. Biggers Sr., but did not possess the original numbering system. These drawings include many of the joint efforts Biggers was involved in as well as firms labeled by multiple architects.

M- The Miscellaneous grouping contains many unnumbered plans and material that does not relate to other groups. Some drawings from Biggers and Lockwood as well as other architects can be found in this section as well as many surveys by McMath and Blackmon Jr.

MS- The maps and surveys comprise this group. A considerable amount of this group contains maps that have the schools and districts labeled as well as varying other statistics and information about the schools written on maps.

SD- The Muscogee County School District has its own group. These are plans and drawings for schools, administrative buildings, and surveys of plots.

TL- These drawings are connected with three architects from the Lockwood Family, T. Firth Sr., T. Firth Jr. and Frank. Frank and T. Firth Sr. worked together briefly as a firm known as Lockwood Brothers.
