Hi, I'm Tom Stevenson and welcome to my YouTube channel.

Today we're going to be looking at seven ways reading construction drawings makes you invaluable.

I'm a professor of construction management, have a long history of training people in construction,

and I can tell you firsthand your ability to really be valuable to your employer,

valuable in your career, and actually move and shake things is how well you can read and understand construction drawings.

So let's dive into these seven points that we'll cover today.

So there's this point that I like to bring up in a lot of my videos, and it comes from Cal Newport.

He's written a lot of books like

Deep Work and other ones, and be so good they can't ignore you.

And one of the ways that you can be so good

that your employer can't ignore you is if you have rare and useful skills such as print reading really well,

understanding specifications, contract documents, and being able to translate that into actual construction practices.

So construction drawing literacy is a really powerful thing.

And we're going to talk about knowledge, understanding, judgment, trust, all of those aspects and how they flow together.

When we think about reading drawings, there's things on drawings that you might not pay attention to,

you know, if you're not really aware of it like this little corner here

if you look at it it's got this little aspect

that points out right and it's like sometimes people doing form work they could miss something like

that and just make it square the corner i've blown it up like i'm looking at it in close

and it says like there should be a hundred millimeters there

but you should be able to see this round dot here here

and say well what is

that what is this well this is a steel beam that's going to go into a beam pocket, but this round dot, what is that?

You could actually look at the reference in the construction notes and it'll give you an indicator of what it is.

That's in the basement.

You look on the first floor, you see it here.

Oh, over here, the round dot goes right across and there's a steel beam on top of it.

Oh, and it's got 180 millimeter by 10 millimeter thick plate, right?

Right.

That could be like an eight inch by three eighths inch thick steel plate,

if you will, that is welded to the beam.

So you have to pick these little things up when you see it and you have to try to visualize.

Well, why is that there?

Right.

Why is that there?

Well, that goes from floor plan to elevation drawing.

Oh, this sticks out.

Right.

This is sticking out.

The second floor is not sticking out.

It's brick.

So the house is brick veneer, face brick.

Okay, so something has to support the brick going across the front of the house because this sticks out, right?

And we look back here.

Oh, this is going to be what supports the brick.

So we have to be thinking about how all these things connect and being able to look at the different drawings.

And then we have to be thinking about, you know, the special requirements.

If we're managing the project of procuring the steel the special

requirements from the form work to installing the steel the brick

work how the joists are going to tie in these all require skills in reading drawings

or you don't see it and then you're reacting to things

that aren't correct so like in the basement there's that part

that sticks out you have to visualize what we're looking at

and that's a real strong tool all right so basically

that it nib that was 100 millimeters four inches sticking out there's the steel beam it's resting

if you looked up number 38

you see it talks about the thickness of the steel beam it's an astm such and such

and basically it's going to have a steel plate

that's a certain size here's the other steel beam that's intersecting into the beam pocket here is

that steel plate you can kind of tell by basically it looks like there was some mud on this

but basically it's welded on here the post is welded to the steel beam

and there's the brick that's sitting on top of it.

And here's coming up through the floor.

You have to be able to visualize all these things.

And then there's going to be some things that you probably have to improvise on the project with the framer,

because you're going to make sure that you don't have a joist coming in here.

And the framer is going to make sure that this is going to be room for the steel.

So they basically put a double header in here just to support that space there.

So it's not interfered with.

So there's a whole bunch of little steps that go that's involved with this.

So you really want to review the drawings, visualize the finished building.

Not everybody's always that good at that.

And one of the reasons is these are orthographic drawings.

They're flat.

You don't see depth.

I have to look at a floor plan, side elevations, plan view to see the depth.

And that's a tool that you have to, when you get a new set of drawings, really sort of...

systemize like you're walking through the building you're walking around the building BIM can help BIM can help

if you've got a 3D model of something

that can help you can see it 3D you can remove layers

so that you could see it at different stages depending on the level of BIM

that it has does it have mechanical systems in it etc duck runs plumbing pipes etc to what level

and of course if you get into things like data centers

and things like that there'll be BIM drawings will be a digital twin where you can see everything

because you got to work out all the interferences in the digital twin before

you do it on site all right so that can be really helpful

but you also have to understand that the map is not always the territory

so you got to sort of be looking ahead for possible problems possible interferences possible things that could trip you well.

And if you really understand drawings really well, then that's going to be really helpful from that perspective.

And you're visualizing, as I said, like what does the finished building look like?

What does this finished building actually look like?

It looks pretty close, right?

There's going to be some differences.

There's a difference here.

There's a few differences, but it looks pretty close.

So that's what you're trying to get clear in your mind

so that you can construct it

but you also have to think through the different layers

that are involved and so the difference between reading a drawing i guess the difference between knowledge

100

and understanding that's a thing all right that's a thing

101

it's one thing to know the name of something

102

it's another thing to really understand what it does how it

103

goes in some of the restrictions some of the constraints right

104

so you know reading symbols memorizing symbols notes and things like

105

that that's great and that's really good

106

but we've got to understand well what does

107

that mean to me like it might mean something

108

if it says duplex outlet height as noted all right

109

so they'll put the height of the outlet well where are they going to do

110

that they're most likely going to do that like above kitchen cabinets above vanities

111

because you want to plug that's above the splash of the countertop

112

so whatever height it is it has to work out

113

or it could be in the back of a cabinet

114

or a microwave shelf or something of that nature

115

so you have to understand okay great

116

this is a outlet duplex receptacle duplex receptacle outlet different words meaning the same thing

117

and this is a height oh and then

118

if it's not doesn't say anything

119

it's going to be the standard height basically 12 inches off

120

the floor these little nuances of space between the spaces that you got to really kind to start to anticipate, right?

121

And applying it, anticipating these constraints,

122

anticipating these interference things that are going to cause ripple effects in your ability to manage the project.

123

If you're able to do that and stick handle around it, you are valuable.

124

You are really, really valuable from that perspective, all right?

125

So I use this Richard Feynman quote, he was this

126

Nobel laureate physicist, renowned teacher too, professor, and there's a difference between knowing something and understanding something, right?

127

There's a difference between knowing something and understanding something.

128

Okay, you know that it is called a lintel over a doorway.

129

In Canada, we call it a lintel.

130

Everywhere else, they call it a header, but a lot of people here, they call it a header.

131

The problem with that is the building code only has headers

132

and floors okay fine so you just should know the difference in the terminology

133

so you can look stuff up you understand the building code

134

you can talk to a building inspector on their language those kind of things are important

135

but then if you really understand it you know what function it's performing

136

and it's distributing loads off to the sides and it's carrying live

137

and dead loads and basically how you frame it is important

138

and all of these other aspects now you're understanding it now you're getting it

139

and it's coming through so that's that's helpful from that perspective

140

if you can spot problems early whatever the problems might be differences between architectural structural especially

141

when you get into commercial work we've got separate drawings done by different consultants

142

and are they in alignment with each other

143

because sometimes we're all human nobody I've never seen a set of perfect drawings ever

144

I've never seen a perfect trade work without even the slightest mistake there's always room for improvement right

145

and so if you can spot something there's little things

146

that probably aren't going to be a big deal but

147

if you can spot something oh we better do something about this right

148

now that'll save us hours weeks of rework later on you have value when you do that right and so never over.

149

Never assume the drawings are 100 % correct, because they aren't.

150

And there's this old saying, I don't know if you've heard it, but when you assume, you make an ass out of you and me, right?

151

So it's just this little play on words that when I was a kid that used to always say.

152

So we don't want to assume, we want to know, and we want to understand.

153

We want to go from knowing to understanding.

154

See the big picture.

155

So looking at it, basically, when you're looking at, you're looking at how does all these parts fit together?

156

And you're looking at the different drawings.

157

You're looking at from a floor plan.

158

And then there might be a section detail.

159

And then you're looking at the section detail.

160

And what does this tell me?

161

And sometimes when you look at the floor plan, you're kind of like, okay, there should be a detail on this.

162

Like here, this is like a close -up of a stairs going into a basement

163

and you see this little cutting plane line and it's saying E and so that tells me there's a detail somewhere.

164

I'm also seeing the steel.

165

I know when I see a stairs on an outside wall there's going to be some reinforcing in

166

that concrete because it's laterally unsupported typically.

167

All right so typically there's going to be some reinforcing in there

168

so my spidey sense is kind of saying oh what's the rebar?

169

Oh what's this line?

170

It's rebar.

171

Oh where's the detail?

172

Oh E.

173

Okay, so then I go and I look for detail E.

174

And of course, it says laterally unsupported foundation wall.

175

And then it's telling me, oh, 320M rebars, so 20 millimeter diameter rebar, right?

176

Basically like a three quarter inch rebar at four inches on center, foundation wall, right?

177

And then it's saying how far to extend the rebar beyond.

178

This is kind of like a standard detail here.

179

And it's saying one and a half inches of cover.

180

So that's talking about you got to have it covered by at least one

181

and a half inches it's going to be under tension this wall right

182

because the garage slab is over here this earth has been backfilled

183

but there's nothing like there's no floor framing to support

184

that area so that puts this wall under tension and concrete

185

when it's under tension it's very weak

186

so you put rebar in there it's going to be under tension near the top of the wall

187

you put rebar in there it's going to hold it in place it's not going to have a problem

188

and basically that's to offset that section not being laterally supported by like a sill plate

189

and floor joists etc

190

so it's just being aware of something like okay

191

i see this my i'm starting to think where is something else

192

and that's that difference between you know just knowing

193

that okay this looks like something but understanding why what's behind it

194

and then being proactive about not having it be a problem.

195

Watch what, catch what others miss.

196

So that's what I'm saying too, right?

197

Catch what others miss.

198

If basically we miss things, you know, that's going to, in estimating that causes a problem in,

199

if there's something in the specifications that we miss, well, did we account for that in the estimate?

200

Did we order that ahead of time so that we have it?

201

Because a lot of things today have very long lead items.

202

You know, you order something today, you might not get it for three, four months or longer, right?

203

Some advanced equipment, sometimes it can take eight months, a year or plus in a certain amount of projects.

204

I'm thinking again, data center scene, that seems to be the buzz of the day, right?

205

Plan and schedule better.

206

Well, I can break things down.

207

I can look at it and I can, I always think about when I teach project management and planning and scheduling, you can check my playlist.

208

I've got a whole bunch of courses on my playlist of different topics that may fit with what you're after.

209

One of them is understanding construction drawings, residential construction.

210

They're all there.

211

And plan and schedule better.

212

If I look at a set of drawings, I can start to break it down.

213

What are the steps to actually construct this project?

214

And I can figure out then by each step, looking at it when I understand what's being done, how long it's going to take.

215

So I can work out durations.

216

I can work out sequences, predecessors and successors, but I have to know how to read the drawings

217

and I have to understand what's on the drawing so I can figure out who needs to do what.

218

But at that core, if you develop that really good being able to read and understand construction drawings, again, great value coming for you.

219

Ask better questions.

220

Well, there's going to be a lot of stuff.

221

We call it an RFI, request for information a lot of times in low -rise

222

you might say i work in low -rise residential i've never heard of rfi

223

if you work in institutional commercial industrial

224

and all the other sectors you'll have heard of it

225

and you may in residential um

226

but it's not sometimes it's a little bit more wild westy

227

if we if you want to use the term regardless rfi just means request for information it's documented

228

so that if there's any dispute later on you've got the documentation in place and if you're going to ask questions,

229

you want them to be detailed enough because you don't want this back and forth nonsense, right?

230

Because it just wastes time.

231

So if you can be clear on what's missing on the drawings, because very often there's, you know,

232

a dimension missing, a speck on something, what it should be.

233

You want a clarification.

234

If you can be very clear and specific, then you'll get a clear and specific response.

235

And that wastes less time.

236

It wastes less of the consultant's time.

237

It wastes less of your time.

238

And because you're so good at reading drawings, when you are asking a question, it is for a valid reason.

239

You shouldn't be asking the consultant to try to teach you how to read drawings by asking a gazillion questions.

240

You should be not wasting their time, respect for others, and working as diligently as you can to get better at reading drawings.

241

Prevent costly mistakes.

242

Yeah.

243

So with reading construction drawings, there's a lot of detail.

244

And if you look at a detail like this, okay, and this is like a section detail for a house.

245

This was a Toronto Area Chief Building Officials Committee detail,

246

but it really illustrates well the different components that are involved in this house,

247

right you've got a concrete foundation wall you've got a brick veneer

248

it's got a lot of details in what you can

249

and can't do these are pretty much referenced

250

because chief building officials they've got a lot of references to

251

code minimum code requirements of the time vented soffit the hatchings

252

you know therefore in this case it's showing it like it's bad insulation probably more than likely be blown insulation

253

but bad insulation brick airspace understanding what these things are you

254

know the anchor bolt for the sill plate the dash line meaning a continuous air barrier

255

which is also serving as a vapor barrier in this case

256

so that's why it says continuous air vapor barrier

257

and then over here this would be what we call a header wrap

258

that goes around on the inside the vapor barrier would actually come up on the inside over here

259

there it would be acting as an air barrier there's a whole bunch of technical knowledge that goes into

260

understanding these components and reading drawings and understanding what the hatchings are for this.

261

This tells me that's styrofoam.

262

I can see styrofoam.

263

I can see styrofoam.

264

I can see bad insulation in here.

265

So you're looking at it and you're picking up things very quickly,

266

but then you're also thinking about the construction process and some points of problems that may come up,

267

may or may not come up, but you're anticipating them.

268

You want to become the go -to person.

269

Know where to find answers and when to ask, right?

270

You're good at, nobody knows everything.

271

So I didn't mean to scare you by saying, you know, you're not to be asking the consultant a million questions

272

because they're not going to want to see you coming if it's stuff that's just kind of wasting their time.

273

But on the other hand, if it's stuff that you're asking now

274

that makes both of you look good down the road because it hasn't really gone too far, that's a big positive.

275

And if there's things happening on the site, the trades, if they know that you really, really understand how this works,

276

it gets you a ton of respect.

277

It gets you a ton of respect.

278

So building this core skill really helps you and it helps everyone.

279

And of course, in an industry that is cyclical, which construction is, there's good times there's not

280

so good times there's average times

281

and in tough times your employer is not going to want to let you go they may let others go

282

but they're not going to want let you go

283

because you're basically the knowledge center that everybody turns to and

284

if they do let you go that's at their peril

285

because the industry is a big industry

286

but it's a small industry it won't

287

you won't have much trouble getting another job that's kind of been my experience in construction.

288

And I've seen it play out thousands of times with different students over the years.

289

So I'm going to suggest that you practice this daily for the next month.

290

Because if you listen this far, you're into this.

291

If you haven't, you're gone.

292

Okay.

293

Start with a set of drawings.

294

Try to get access to a set of drawings.

295

Visualize the finished building.

296

And if you're saying, well, how can I get a set of drawings?

297

Sometimes it's not that easy depends where who you're working for etc

298

but sometimes it's pretty very easy all right other times

299

if that's the case i'm coming up the next slide

300

i wrote a textbook you can look in the description where you can get it it comes with drawings questions

301

that you can work through knock yourself out with

302

that watch a lot of my videos you'll pick

303

that up from the playlist but really you got to practice this is requires like I think.

304

determine practice and the more consistent you are at it the quicker it comes

305

and the quicker it comes the more valuable

306

you you are sooner right why why take 10 years to really be able to get this down

307

when you could do it in five with some discipline visualize the finished building

308

imagine what makes up the walls floors layer by layer trade by trade

309

so visualize the finished building want pretend you're walking around the outside pretend you're walking through it

310

and then imagine how this is going to come together and what's behind these components.

311

Start looking through the details, the construction notes.

312

Think of the sequencing, what order things could do, what things could happen at the same time, right?

313

Look at the references that you see on the drawings to the notes

314

and try to see how they connect and what makes sense and what maybe doesn't.

315

We're living in a world of AI now.

316

Something doesn't make sense.

317

Take a picture of it.

318

Ask some questions of AI.

319

I'm not saying it's going to be 100 % right, but it can help get you there.

320

It can help get you there.

321

Pay particular, can you explain the process to someone else?

322

That's the best way.

323

You start teaching someone else this process.

324

If you're a student and you help other students to learn it, you figure it out even better along the way and more quickly.

325

So as I said, I've written a textbook.

326

This is in its fifth edition currently there'll be another one coming out down the road at some point

327

so we're basically i'm just saying whatever edition you actually get your hands on it's fine

328

if that's this is a self -learning pace uh from

329

that perspective and it's based on the national building code of canada

330

but you know wherever you are

331

if you do wood frame construction this book would be helpful and be helpful as a foundation.

332

So learn to see what others miss.

333

Use knowledge, use judgment, build trust that people feel that you actually know what you're doing.

334

This over time, that builds trust, that builds relationships, that really solidifies your value with companies, your value in the industry.

335

All right.

336

And again, you can watch a lot of the videos on the playlist and I want to hear from you.

Wat is de Shadowing-techniek?

Shadowing is een wetenschappelijk onderbouwde taalleermethode die oorspronkelijk is ontwikkeld voor professionele tolkentraining en gepopulariseerd door polyglot Dr. Alexander Arguelles. De methode is eenvoudig maar krachtig: je luistert naar native Engelse audio en herhaalt het onmiddellijk hardop — als een schaduw die de spreker volgt met slechts 1–2 seconden vertraging. In tegenstelling tot passief luisteren of grammaticadrills, dwingt shadowing je hersenen en mondspieren om echte spraakpatronen tegelijkertijd te verwerken en te reproduceren. Onderzoek toont aan dat het de uitspraaknauwkeurigheid, intonatie, ritme, verbonden spraak, luisterbegrip en spreekvaardigheid aanzienlijk verbetert — waardoor het een van de meest effectieve methoden is voor IELTS Speaking-voorbereiding en echte Engelse communicatie.
