No more than 12 inches may be removed from either girder end.

If more than 6 inches is removed from a girder end, include in the modification proposal stamped calculations from a Professional Engineer indicating the viability of the proposed modification. Calculations must include:

Required moment and shear capacity.
Actual moment capacity of the modified member, obtained using PGSuper or another acceptable analysis program.
Actual shear capacity.

In most cases equal amounts should be removed from each end if the total length to be cut exceeds 6 inches. However, that would not be a viable solution if a beam end is being cut in order to eliminate damage or when a beam end contains an anchor slot.

The Area Engineer and MTD Engineer must approve modifications. All parties, including the Fabricator, Contractor, and Engineer, must agree that trimming will not result in any unacceptable issues related to deck forming, slab or haunch thickness, camber, or plan profile deck geometry.

The girder must be modified as required for use in its new configuration, including but not limited to blockouts, inserts, hangers, and bevels.

When the strand pattern differs from the destination design, or if more than 6" is cut off one or both beam ends, a replacement shop plan for the permanent record must be provided that indicates all characteristics of the candidate girder that differ from the originally specified girder.

Include dual girder identification by permanently marking the inside face of the girder, clearly indicating which is the previous girder I.D. and which is the current I.D. Fabricator or Contractor must send written notification to the Area Engineer informing them of the circumstances of the dual marked girder for their information and records.
