STRUCTURAL DETAILER RESPONSIBILITY ON BRIDGE DESIGN

STRUCTURAL DETAILER RESPONSIBILITY
Bridge Design Tutorial


The structural detailer is responsible for the structural plan sheets. The plans shall be neat, correct, and easy to follow and drawn to scale. The structural detailer may also assist the designer and design checker in such areas as determining control dimensions and elevations, geometry, and calculating quantities.

Some detailing basics and principles:

a. Refer to BDM for detailing practices.

b. Provide necessary and adequate information. Try to avoid repetition of information.

c. Avoid placing too much information into any one sheet.

d. Plan sheets should detail in a consistent manner and follow accepted detailing practices.

e. Provide clear and separate detail of structural geometrics. Use clear detailing such as “stand alone” cross sections or a framing plan to define the structure.

f. Avoid reinforcing steel congestion.

g. Check reinforcement detail for consistency. Beware of common mistakes about placement of stirrups and ties (such as: stirrups too short, effect of skew neglected, epoxy coating not considered, etc.). Check splice location and detail, and welding locations.

h. Use cross references properly.

i. Use correct and consistent terminology. For example, the designation of Sections, Views, and Details.

j. Check for proper grammar and spelling.

k. On multiple bridge contracts, the structural detailing of all bridges within the contract shall be coordinated to maximize consistency of detailing from bridge to bridge. Extra effort will be required to assure uniformity of details, particularly if multiple design units and/or consultants are involved in preparing bridge plans. This is a critical element of good quality bridge plans.

l. Refer to the Bridge Book of Knowledge for current special features and details used on other projects.
