TEHOMIC TC-1
Confined-Space Drilling Platform.
A modular electric drilling system for the urban subsurface. Engineered specifically for access-restricted environments where conventional rigs cannot operate.
Section 01 · The operating envelope
System specifications.
The TC-1 is designed backward from the industry's strictest access constraints. If a standard two-person crew can access the space, the TC-1 can drill it.
CODENAME · TC-1
Confined-Space Drilling Platform.
Modular electric drilling system. Disassembles into components a two-person crew can carry through a 32-inch doorway. Reassembles inside the work zone. Drills cased vertical shafts under sensor-assisted, closed-loop control with the operator outside the immediate hazard zone.
Fixed design constraints
Access requirement
32 in / 80 cm Standard doorway · stair-capable in modules
Portability
Modular, hand-carried No crane, no forklift, no vehicle access required
Power source
100% electric Mains or battery pack · zero combustion exhaust
Emissions
Zero Compliant with OSHA 29 CFR 1926.800 for enclosed-space operation
Safety control
Sensor-assisted, closed-loop Operator manages the system from outside the immediate hazard zone
Bore product
Cast-in-place concrete Direct contact with foundation · no steel needles required
Target drilling specifications · validating in POC
Bore diameter
300–500 mm range Accommodates ASME A17.1 cylinders and standard micropile classes
Design depth
Up to 40 m POC unit currently targeting 4 m
Setup time
~1 day Door-to-drilling, single two-person crew
The fixed design constraints are core engineering parameters set by the access
constraint itself. The target drilling specifications are design-intent values
currently being validated on the prototype. The first POC unit becomes operational
in summer 2026; specifications publish as they are measured, not before. The
device itself is not shown at this stage.
Section 02 · Primary applications
Three urban environments.
The platform is engineered to execute precise vertical bores in three specific access-restricted environments. Elevator pit re-drilling is the first commercial application. The other two follow in sequence.
Application 01 · First commercial target
Elevator pit re-drilling.
Modernization of pre-1971 single-bottom hydraulic cylinders to meet ASME A17.1 (NA) or EN 81-80 (EU) codes. Legacy holes fail the re-drill 10–20% of the time. Conventional workarounds require structural roof removal or lobby demolition.
The Tehomic application
The TC-1 assembles directly inside the existing elevator pit. It drills a fully cased, plumb bore sized for modern PVC-lined assemblies — without requiring building demolition or extended facility downtime.
Application 02 · Pilot track
Inner-city underpinning.
Conventional underpinning relies on perimeter-inward excavation, which is ineffective for zero-lot-line buildings, party walls, or settling interior load-bearing columns.
The Tehomic application
Deployed directly onto the basement floor or via a discreet exterior pit. The system drills and installs cast-in-place concrete micropiles precisely under the interior structural elements that conventional equipment cannot reach. Multi-mode: interior basement, exterior access pit, or both — whichever the site geometry permits.
Application 03 · Exploratory
Confined-space drainage.
Retroactive hydrostatic pressure relief in occupied buildings — parking garages, transit stations, deep basements — is limited by ceiling clearances and strict ventilation codes that prohibit diesel rigs.
The Tehomic application
The TC-1 navigates standard building corridors to reach gravity-low points. It drills deep, perforated relief shafts to punch through impermeable clay and relieve lateral soil pressure on the surrounding structure — all while the facility remains open.
Section 03 · Company status & roadmap
Where the hardware is, where it is going.
We are a specialized engineering team based in Israel, combining mechanical, controls, and field-construction disciplines. We are not building a general-purpose construction robot. We are building a specific tool to solve a specific physical constraint.
Current stage
The TC-1 is in active engineering build. Our first operational POC unit is targeted for summer 2026, and we are actively scoping pilot conversations for Q4 2026.
Roadmap
- Q1–Q3 2026 Engineering specs locked. Prototype in active build. Bench validation against concrete, rebar, and bedrock.
- Summer 2026 First operational POC unit.
- Q4 2026 First commercial pilot in elevator pit re-drilling. Per-shaft pricing benchmarked against demolition avoided. Currently scoping pilot conversations.
- 2027–2028 Scale to 3–5 modernization partners. First underpinning pilot with a structural-engineering partner.
Long-term, the platform is built for autonomous operation. Today, the operator runs it from outside the pit.

Section 04 · Engage
Two channels. Same address.
We operate on a per-shaft service model to capture the value of demolition avoided. If you are an elevator modernization contractor facing the re-drill bottleneck, or a potential partner looking for a deeper technical brief under NDA, we are actively scoping Q4 2026 pilot projects.
