I've been handling elevator service and modernization orders for about seven years now. In that time, I've personally documented over 40 significant mistakes across our team, totaling roughly $180,000 in wasted budget and delayed projects. This isn't something I'm proud of, but I've learned to maintain a checklist to prevent others from repeating my errors. Today, I want to walk you through a comparison that I think is one of the most important for anyone dealing with a thyssenkrupp escalator or lift project: the difference between planning for the 'pitless' and the 'traditional pit' installation.

We're going to compare two specific projects from 2023. One was a textbook, well-planned installation for a new office building. The other was a retrofit for a client who wanted a 'quick fix' without dealing with the full structural implications. The comparison isn't about which brand is better—it's about the cost of not knowing what you're getting into.

The Two Approaches: A Quick Framework

Before we dive into the nitty-gritty, let's set the stage. We're comparing two different ways of installing a new elevator system in a mid-sized commercial building:

• Project A (The 'Traditional Pit'): A full-scale, planned installation of a thyssenkrupp passenger elevator that included a new concrete pit, proper overhead clearance, and a machine room.
• Project B (The 'Pitless' Retrofit): A thyssenkrupp pitless elevator model, designed for buildings without the room—or budget—for a traditional, deep pit. This was a retrofit for a building built in the 1980s.

The key question for both wasn't just 'which is better,' but 'which hidden costs will kill your budget and timeline?' Honestly, I wasn't sure which one would end up being the bigger headache when we started.

Dimension 1: Speed of Installation vs. The 'Hidden' Prep Work

This is where the Pitless project initially looked like a huge win. The sales pitch is straightforward: less digging, less concrete, faster install. In theory, you can go from order to operational in a few weeks instead of months. And for Project B, that was mostly true. The actual installation of the thyssenkrupp unit itself was remarkably fast—about 5 days from delivery to first test run.

But here's the surprise. The 'pitless' part doesn't mean 'no work.' For Project B, the structural requirements for the new pitless elevator system were actually more stringent in some areas. The existing subfloor wasn't strong enough to handle the new loads without significant reinforcement. We spent three extra weeks and about $18,000 just beefing up the slab. On Project A, this was all part of the upfront planning. The pit was dug, poured, and cured according to the spec. The elevator install was delayed by a month, but it was a scheduled delay from the start. The Pitless project's delay was a nasty surprise.

"Never expected the 'quick' install to be the one that needed the structural fix. Turns out, a 'traditional pit' is a known quantity. A pitless retrofit often involves discovering what's underneath your floor."

Dimension 2: The Long-Term Cost of Maintenance

I've seen many people (including my former self) assume that a pitless elevator is cheaper to maintain. The logic is: fewer moving parts in the pit, less to go wrong, less water ingress issues. After running the numbers on these two specific projects for about 18 months post-install, the picture is different than I expected.

Project A (the traditional pit elevator) had its standard quarterly maintenance contract. It was predictable. We budgeted $4,200 per year for full maintenance, and we spent $3,950 in actual service calls. It was boring, which is exactly what you want.

Project B (the pitless unit) was a different story. The first year, the maintenance contract was actually more expensive—$5,800. Why? Because the specific thyssenkrupp pitless drive unit required a technician with specialized training that wasn't standard for our local crew. The surprise wasn't the price difference. It was how much hidden value came with the 'expensive' option—in this case, the traditional system had a more standard, easier-to-service setup. We ended up paying a premium for specialized labor on the 'modern' system.

It's kind of like buying a car with a unique engine. Parts and labor are harder to find.

Dimension 3: The 'Baseboard Trim' and 'Pocket Door' of Elevators (Aesthetics & Space)

Let me get a bit off-topic for a moment. You mentioned keywords like 'baseboard trim' and 'pocket door'. Those are things you worry about when you're finishing a space. They're the last 10% of the project that takes 50% of the mental energy. Elevators are the same way, but most people get distracted by the machinery and forget the finish.

On Project A, the traditional pit setup gave us a perfectly level, flush landing on each floor. The alignment was perfect. We could install the baseboard trim right up to the edges with no weird gaps. It was clean.

On Project B (the pitless build), we had a 1/2-inch difference in floor height at one of the landings because of an existing structural beam that we couldn't move. The elevator cabinet was flush, but the threshold had a slight ramp. To fix the visual, we had to cut custom baseboard trim and build a transition piece. It wasn't a functional issue, but it drove the interior designer crazy. It took three visits from the finish carpenter to get it right, adding another $2,000 to the project. In the world of commercial construction, that's a deal-breaker for some architects.

Dimension 4: The 'Hidden' Cost of Doors & Emergency Access

Speaking of pockets, a lot of people ask about 'pocket door' setups for the hoistway. That's a niche application, but it highlights a crucial comparison point. In our traditional pit project, the hoistway was a standard masonry shaft with swing doors. It was cheap, simple, and the fire inspection passed in one go.

For the pitless project, we had a space constraint inside the building. We considered a 'pocket' style hoistway door system. The cost wasn't just the sliding door hardware—it was the additional wall structure needed to house the pocket. We discovered that retrofitting a pocket-style door into an existing wall for a non-standard pitless system required custom framing and a more complex fire suppression system. The fire marshall made us add a sprinkler head inside the 'pocket' area, which was an oversight in our initial planning.

That single sprinkler head, plus the pocket framing, added $3,500 to the budget and a 2-week delay in our schedule.

The Bottom Line: Which One Should You Choose?

So if you're trying to answer, 'how much does a garage door cost?' you're asking the wrong question. The garage door itself is just the start. For an elevator, the unit is just the start.

• Choose the traditional pit (Project A approach) if: You have the structural freedom and budget for the traditional install. It is more predictable, easier to service, and generally leads to fewer aesthetic surprises. It is the 'boring' choice, which is the best choice.
• Choose the pitless option (Project B approach) if: You have no other option. The building physically cannot accommodate a pit, or the cost of digging one is prohibitive. But you must budget for an extra 15-20% contingency fund for structural surprises, custom maintenance contracts, and finish carpentry details.

The truth is, on Project B we saved the client about $25,000 on the initial installation work. But we spent nearly $30,000 on the hidden costs we didn't plan for. In the end, both projects cost about the same, but one was a predictable, low-stress timeline, and the other was a headache.

In my first year (2017), I made the classic mistake of ignoring the pit requirement and assuming a 'pitless' job would be easier. After the third rejection of the final inspection in Q1 of 2024, I created our pre-check list for elevator installations. The biggest lesson? Always budget for the unexpected, and never assume one system is inherently cheaper than another until you've run the full comparison.
