Office Buyer's FAQ: Caterpillar Parts, Caterpillar Nests & Other Real Requests

When I took over purchasing in 2020, nobody warned me the job would include Caterpillar machines, tent worms, and a classroom game called Blooket. I'm the office administrator for a 150-person construction services company, managing roughly $2.4M in annual purchasing across 8 vendors. The "office buyer" title covers a lot more than ordering paper clips. These are the questions that actually show up in my inbox—with the answers I'd give someone starting this job.

Here's what this FAQ covers:

• Ordering Caterpillar parts without overpaying
• Caterpillar nests in trees near job sites
• What a cinnabar caterpillar is (and isn't)
• Why we don't buy a Bentley GT for the company
• Whether Eddie jackets are worth the cost
• How to get the Wise in Blooket

How do I order Caterpillar parts without getting burned?

First rule: don't compare sticker prices alone. In 2022, I saved the shop $340 by ordering a cheaper "compatible" hydraulic filter for our Caterpillar loader. It failed four weeks later. Between diagnostics, downtime, and the replacement part, that filter cost us about $2,900. The genuine part wasn't that much more expensive—but it didn't fail.

That's not to say every aftermarket part is bad. It means the savings weren't worth the risk on a critical component. What I do now: confirm part numbers through the dealer network first, get a written quote with freight and availability, and verify the invoice shows line-item detail. The vendor who can't produce a proper invoice is a red flag. I once ate $2,400 in rejected expenses because a supplier gave us a handwritten receipt, and finance wouldn't touch it.

Base price, freight, installation labor, downtime risk—all of it belongs in the comparison.

The real calculation is total cost of ownership. When you're scheduling maintenance around a shutdown, the value of a guaranteed delivery date isn't speed, it's certainty. A part that "probably" shows up is not a plan. We applied this thinking in our 2024 vendor consolidation project: cut 20 suppliers down to 8, and ordering time dropped by about six hours a month.

Caterpillar nests in trees near our job site—do we need to act?

If your crew spots thick, silky webs wrapped around tree branches, that's a tent caterpillar nest. Not an emergency, but it needs a decision.

In 2023, our site supervisor flagged a cluster of nests along an access road we were clearing. I called an environmental consultant before we did anything. Cost: $180. Reason: if those were nests of a locally protected species, removing them could mean a fine in the $5,000 range. It took one call to confirm we were clear.

The process that works for us: identify the species first, then act. If it's unprotected and on your own land, cutting out the affected branch is usually fine. If the site borders wetlands, public land, or a conservation area, get the assessment first. State extension services publish the local species list, and most of them answer email within a day.

One thing I'll add: don't let a panicked site manager push you into spraying before you know what you're dealing with. Most of these issues are preventable with proper identification. Spraying an active nest without checking the species is how you turn a small problem into a regulatory one.

What is a cinnabar caterpillar, and should we worry about it?

Short answer: it's the orange-and-black striped larva of the cinnabar moth, and it's actually a helper. It feeds on ragwort, a weed that's toxic to grazing animals. If you find cinnabar caterpillars on company land, they're eating the problem for you.

The cinnabar moth is common in the UK and parts of Europe, and it's been introduced in North America as a biological control for tansy ragwort. So if someone in the Pacific Northwest sends you a photo of striped caterpillars on a weed, that's what they're looking at.

No action needed for the caterpillars themselves. Their hairs can irritate skin, so we keep gloves in the field kits and tell crews not to handle them bare-handed. What's worth doing is checking for ragwort in grazing areas. If you have livestock or lease pasture, ragwort control is a real issue. County extension offices publish fact sheets on both ragwort and cinnabar moths—useful when a site manager sends you a mystery bug photo at 7 a.m.

Can we buy a Bentley GT as a company vehicle?

In 2024, one of our managers requested a Bentley GT as his company car. I had to say no—and it wasn't just about the sticker price.

Here's the thing: a company vehicle is a business asset, and the question isn't only "what can we afford?" It's "what does this say to the client when you pull up?" For a construction services company, a six-figure luxury coupe reads as overcharging customers. It damages the exact impression we work hard to build.

This is the quality perception issue that people miss. Clients remember the small stuff. A clean, logoed work truck does more for your reputation than a flashy personal vehicle ever will. And running a Bentley GT—insurance, maintenance, depreciation—costs triple what a properly equipped pickup costs per mile.

We didn't have a formal vehicle request process at the time, so the request bounced between operations and finance for two weeks before landing on my desk. That was the moment I built a simple approval chain: business case, budget check, sign-off from both departments before I talk to any dealer. The third time a request like this came in, the form was ready. Should have built it after the first.

Are Eddie jackets worth it for field staff?

When people say "Eddie jacket," they usually mean Eddie Bauer's guide or fleece-lined jackets. They keep showing up on our field crew's wishlist—and for good reason.

I used to buy budget workwear to save maybe $15 per piece. Then a crew member wore a cheap jacket on a wet job, got soaked, and we lost productive hours anyway. That $40 jacket cost more than the $90 one, if you count the failed day.

Now I order better jackets in smaller batches each season and issue them to senior field people first. Two things happened. First, they last roughly twice as long. Second, clients started treating our crews differently on site. Clean, consistent gear changes first impressions.

Workwear is one of those decisions that looks small until you see it on a client's site. The logo on the jacket is your brand walking around. If the gear looks cheap, people assume the work is cheap—and that's a perception you can't fix with a discount.

Look, I'm not saying budget options are always bad. But after five years of watching the cheapest option fail, there's something satisfying about finally having a system that works.

How do you get the Wise in Blooket—and why does an admin need to know?

Yes, this is a real procurement question. Our receptionist's daughter needed help, which meant I needed help, because I'd never heard of Blooket.

Turns out, to get the Wise character, you buy Blook boxes from the Medieval pack using tokens. Tokens come from playing and hosting games—correct answers earn them, and winning matches pays a bonus. The practical strategy: save tokens and buy boxes in batches instead of one at a time, sell duplicate Blooks to recycle tokens, and keep going until Wise drops. The drop rates are published, so you can calculate your average cost before you start.

Why does this belong in an office buying FAQ? Because it's the same principle as parts ordering. Small repeat purchases with random outcomes waste budget unless you understand the mechanics. Whether it's Blooket boxes or hydraulic filters, know the drop rates and the real cost before you spend.

And honestly? Being useful on the weird requests builds more goodwill than any formal process I've implemented. Not a bad outcome for an afternoon of research.
