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
