Several such drawings are necessary for the description of a building so complex as this one.

When the building is so large as to necessitate the drawing of the elevations at a small scale as shown on Plate 34, it then becomes necessary to draw portions of the elevation at a larger scale so as to describe its parts adequately. Plate 37 gives a scale detail describing a part of the south wall of the church. This shows accurately the shape, size and location of all features of this part of the wall. It locates vertically all windows, doors and other openings. The cut stone parts are accurately drawn and dimensioned as shown, all cut stone joints being located. The approximate size of the stones and general character of the ashlar walls is here indicated in a manner easily distinguished from the cut stone work.

Notice that vertical dimensions are given from the main floor level and the elevation of this floor (118.0) is noted. Attention is called also to the method of dimensioning the batter or slope of the tower wall.

The tower stair, which is built against this wall, is indicated by dotted lines and the risers are numbered for convenience in reading the drawing.

Enough scale details of this kind are drawn to describe all of the outside walls.

[This Section Is Taken Thru The Tower On The Center Line As Though The Observer Were Looking West. The Original Drawings Contain In Addition To This One A Section Thru The Center, Of The Tower And Looking North. These Two Tower. Sections Together.

Than The Architects Detail It Is Impossible To Show The Mouldings, Iron Balustrade Etc. As Accurately As On The Hale Inch Scale Working Drawing. Full Size Details Have Been-Made For. All Of The Mouldings And For The Ornamental. Iron Work. This Method Of Detailing Has Been Carried Out Over The Entire Building Making The; Drawings Very Complete And Easily Interpreted By The Builder.]

[The Partial Piling And Footing- Plans Given Are Sufficient To Indicate The Manner. In Which Such Drawings Are Usually Presented. On These Plans The Columns Are Located And The Footings Are Then Dimensioned From The Column Centers The Piling Which Was Necessary For This Building Is Described By Notes On The Sheet With The Piling Plan. These Notes Give Thee Exact Location Of Each Pile Core And The Depth To Which It Shall Be Driven. In Addition To The Larger. Footing Details Shown Here Are Detail Vertical Sectlons Through The Basement Walls.]

The lot upon which the Cleveland Discount Building Company's building is located is underlaid for some distance with earth of such a nature that it will not support the excessive weight of a building of this size. The depth to which this soft earth extends is so great as to make it impractical to carry the foundation walls down to the solid footing required. When such a condition is met it is necessary to provide some kind of supports down through the soft material to the solid rock or other good footing. These supports are called piles and are long wood or concrete posts. When concrete piles are used, a hollow sheet steel form is driven down as far as necessary and then filled with concrete. Concrete footings are next formed on top of the piling and the building rests on these footings.

It is necessary that each pile be located as accurately as possible and for this purpose a piling plan is made as suggested on Plate 39.

Notice that the elevation of the top of the driven piling is marked on each footing. Thus the contractor who drives the piles knows just where to finish off the top of each pile. The footing sections, see Type-A and Type-B, show how the concrete footings are built on top of the piling. The steel reinforcing rods and the steel girders are shown by solid black lines.

When there are a number of footings of each size and kind, they may be given type numbers or letters as in this case and only one of each type described in detail.

On Plate 43 is a typical small scale elevation and section of a very large building. The actual elevations of this structure are much larger than those of the Grace Methodist Church and consequently must be shown at a smaller scale so that the sheets may not become too large to handle. This makes it impractical to show so much detail and such drawings are therefore useful only in suggesting the elevation as a whole by simple lines and in giving the main vertical dimensions.

The transverse section shows the banking quarters on the first floor and the rental space and light court above.

Parts of the elevations are then detailed at a larger scale similar to that of the church on Plate 37.

Notice that the ornamental metal work and terra cotta is indicated in the simplest possible manner and sometimes only noted.

Plate 44 gives one of a number of large scale details showing the relation of the walls, floors, and ornament to the structural members. It is explained by the note on the plate.
