## 4.1 Sheet Numbers for Bridges and Walls

A. Bridge plans are usually a component set of plans and includes walls. Projects with minor bridge work may include these features on sheets in the roadway plan set or detailed on roadway sheets. When prepared as a component set of plans, assemble the drawings as a separate plans set complete with a key sheet and all bridge and wall sheets, including the existing bridge plans. Number the sheets consecutively with the sheet numbers prefixed by the letter and letter/number combinations “B” for common sheets, “B1” for the first bridge, “B2” for the second bridge, “B3” for the third bridge, etc., “BW” sheets, if necessary, for all walls, and ending with the existing bridge plans, “B1E”, “B2E”, “B3E”, etc., if necessary.

B. Start the sheet numbering with the Key Sheet numbered “B-1”. Continue to use the “B” prefix for all sheets with common details to all the bridges including Structures Standard Drawings. Begin the sheet numbering for the first sheet of the first bridge with “B1-1”. Continue to use the “B1” prefix for all sheets with details pertaining to the first bridge (“B1-2”, “B1-3”, etc.). Number the second series of sheets for the next bridge, if included, “B2-1”, “B2-2”, “B2-3”, etc., continuing to use the “B2” prefix for all sheets of the second bridge. Continue incrementing sheet prefix numbers, “B3-1”, “B4-1”, etc., for each additional bridge included in the plans. To further divide bridge sheets on complex bridge projects, use a Drawing Number box in the upper right hand corner of the sheet (see Section 4.5).

C. After all the bridge plans, place all the wall drawings (including cast-in-place retaining walls, proprietary wall control plans, temporary walls, and sound barriers) using a “BW” sheet prefix. To further divide wall sheets by wall number or type, use a Drawing Number box in the upper right hand corner of the sheet (see Section 4.5). At the end of the plan set, place all existing bridge sheets in one PDF file, using the sheet prefix B1E for the first bridge (number sheets sequentially “B1E-1”, “B1E-2”, etc.) and, if necessary, “B2E” for the second bridge, etc.

D. Number other miscellaneous structures (signs, signals, lighting, etc) for the appropriate component set (see PPM Volume II, Chapter 2) but place the drawing files in the Structures folder (see CADD Production Criteria Handbook, Chapter 18).

E. The preferred sheet order along with the file naming conventions and other CADD requirements are shown in the CADD Production Criteria Handbook, Chapter 18. All the sheets given in the Table may not be required in a given set of plans, while, in others, additional sheets may be necessary. The sheet order should correspond to the work sequence.

## 4.2 Sheet Titles

If more than one sheet is required for a particular sheet type, add sheet numbers in the Sheet Title Block; ex: “General Notes (1 of 2)”, “General Notes (2 of 2)”.

## 4.3 Sheet References for Multiple Bridges and/or Structures

The drawings for a specific bridge may refer to other drawings with sheet numbers beginning with the same prefix letter and number or with the letter "B". Do not use reference from one bridge to plan sheets for another bridge (i.e. “B1-XX” sheets should not reference “B2-XX” sheets).

## 4.4 Sheet Numbers on Projects with Alternate Structure Types

On projects with alternate structure types, designate each alternate for each bridge with a unique number following the "B" prefix (e.g. "B1" and "B2" for bridge 1 alternates; "B3" and "B4" for bridge 2 alternates, etc.). Since the sheet number will no longer correspond to the bridge number, cross reference each alternate with the bridge number in the List of Drawings.

## 4.5 Construction Sequence

A. Construction sequence drawings for phased construction or bridge replacement supplement but do not replace Traffic Control Plans.

B. Show systematic construction stages including:

1.) Construction Joints.

2.) Critical temporary walls (MSE or sheet pile.)

3.) Temporary traffic barriers.

4.) Removal of existing structures.

## 4.6 Optional Drawing Number Box

When developing complex bridges or multiple wall systems, place an additional Drawing number box on the plans to separate components and help in the development of cross references. Drawing letter/number combinations are assigned at the discretion of the designer and should include prefix combinations that correspond to the details on the drawing. When used, place the drawing number box in the top right hand corner of the sheet. The information in the Drawing Number box is only used for cross referencing and plan preparation; no data from the box will used in the electronic Delivery process. For drawing letter/number combination suggestions, see the CADD Production Criteria Handbook, Chapter 18. Optional Drawing Number Box is required on all bascule bridges or bridges with multiple wall types. For projects with alternate designs, follow the Drawing Number with the alternate designation (e.g. Drawing No.: 45, Alt. B).
