Agenda
Project IntroductionMaterials InformationOriginal Construction PhotosUsing Old Pictures for New Construction3D Modeling
Project Introduction
Original dam built in early 1930’sLocated in area with many damsFast-track type project for era l l fBuilt in only a few years
4 units planned, initially built 2 unitsThird unit added in late 1950’sCurrent project requires expansion in
area of fourth unit
Plan Drawing - Original
Dam Cross-Section Materials Information
Concrete in main dam had 1:2:4 (cement:sand:rock) ratioStrength probably around 3000 psi
initiallyReinforcement was deformed ASTM
A15 Intermediate Grade SteelYield strength of 40 ksiThis is a pretty early use of this grade,
normal a few years prior was “Structural” grade which was a 33 ksi yield strength

Using Old Pictures
Show how original construction was doneCan use similar methods for new
constructionconstructionAble to see areas which are now
underwater or inaccessibleProvides confirmation where drawings
differ on callouts
Using Old Pictures (cont.)
Draft tubes are currently underwater
3D Modeling
Original drawings are not always clearNumerous upgrades and changesDeveloping a 3D model from original
d i h l th d idrawings helps the design processUsing historic and modern pictures to
verify details work wellContract drawings are derived from
the 3D model
3D Modeling (cont.)
3D Modeling (cont.) Summary
Old pictures are really neat to look at!Pictures can help with modern
constructionAble to view areas inaccessible todayAble to view areas inaccessible todayCan see original construction techniquesHelps with spatial conflicts
3D is helping to solve some similar issues
