What Boll Engineering Build & Construct does

Boll Engineering Build & Construct BV is a privately held Dutch custom steel and mechanical engineering firm founded in 2001 by Gijs Boll and headquartered in Giessen, North Brabant. The company designs, engineers, and fabricates bespoke steel structures, spud pole systems, winches, and specialized machinery, operating as an SBB-recognized training company for welding and metalworking. Its service offering spans engineering, welding, machining, assembly, testing, and painting, all executed in-house within a facility that supports a stated 40-ton weekly steel throughput.

The firm's flagship proprietary product is a rack-and-pinion spud pole system launched in 2013, positioned as the first of its kind for dredging and offshore applications, with subsequent variants extending to larger diameters (Ø711, Ø914) and hydraulic configurations. It holds EN 1090-1 EXC 3 (structural steel execution class 3) and EN ISO 3834-2 (fusion welding quality) certifications, qualifying it for load-bearing maritime and infrastructure work across the EU. Customers span maritime and shipbuilding (e.g., Neptune Marine, Holland Shipyards), heavy industry (e.g., Tata Steel), dredging and offshore contractors, and public infrastructure (e.g., Gemeente Amsterdam).

Revenue is generated through project-based contracts for custom-engineered steel fabrications and serial-built spud pole systems sold to maritime, dredging, construction, and machine-building clients. Go-to-market relies on direct B2B sales, technical specification-driven quoting, and reputation within niche dredging and shipyard segments. The firm employs 11 staff (6 full-time, 5 part-time), operates without external funding, and has reinvested in two facility expansions (2015 new build, 2018 capacity doubling) to scale integrated production.

Core offering

Boll Engineering Build & Construct BV designs and manufactures custom-made spud pole systems (including the proprietary rack-and-pinion system), spud pole winches, towing winches, steel structures (industrial buildings, bridges, crash decks, architectural steelwork), and bespoke machines for maritime, dredging, construction, and industrial clients. Every project runs through full in-house capability: 3D design (Solid Edge, Tekla Structures), engineering and CE certification, in-house production using an extensive CNC-equipped machine park, and optional on-site assembly with company-owned transport. The company is certified to EN 1090-1 EXC 3 and EN ISO 3834-2 and operates from a purpose-built facility in Giessen, Netherlands.

Product overview

Boll Engineering Build & Construct BV is a specialist in custom-made steel and machine construction since 2001. The company operates a platform-based business model offering multiple integrated products and services: (1) Spudpaalsystemen (Spud Pole Systems) - including the proprietary Tandheugelspudpaalsysteem (rack and pinion spud pole system), Spudpaallieren, and Verhaallieren; (2) Staalbouw (Steel Construction) for industrial buildings and large structures; (3) Machinebouw (Machine Building) for custom machinery; and (4) Engineering Services using Solid Edge and Tekla Structures 3D software. The company also provides Assembly Services and maintains a comprehensive Machinepark workshop. The core differentiator is their innovative, fully custom spud pole systems with modular segments, alongside full-service capabilities from design through production to on-site assembly.

Products and services

• Tandheugelspudpaalsysteem (Rack and Pinion Spud Pole System) Proprietary custom-made spud pole anchoring system using a rack-and-pinion drive mechanism for positioning work vessels and pontoons. Modular segments connect via bolted joints, enabling spud poles up to 32 meters in length, and the design uses two pinions in a compact drive unit that each actuate a rack along the entire pole length with a maintenance-free internal freewheel coupling.
• Spudpaallieren (Spud Pole Winches) Powerful custom winches designed to raise and lower heavy spud poles, featuring a maintenance-free internal freewheel clutch for controlled and powered movement. Built in various sizes for maritime and dredging applications.
• Verhaallieren (Towing Winches) Custom towing winches available in capacities from 2-ton to 100-ton line pull, used for maritime towing, mooring operations, and vessel positioning.
• Staalbouw (Steel Construction) Custom steel construction service covering 3D design, production, surface treatment (galvanizing and powder coating), and on-site assembly for industrial buildings, bridges, architectural features, crash decks, and large steel structures. EN 1090-1 EXC 3 certified for CE-marked structural parts.
• Machinebouw (Machine Building) Custom machine design and manufacturing service combining 3D modeling, strength calculations, fabrication, and installation. Delivers one-off bespoke machines for maritime, dredging, and industrial applications.
• Engineering Services Engineering services including 3D design with Solid Edge, BIM design with Tekla Structures, custom control cabinet development, software programming for machine control, strength and stiffness calculations, risk analyses, and CE certification support.
• Montage (On-Site Assembly Services) On-site assembly and mounting service for steel constructions and machines using company-owned transport vehicles, two assembly vans, and mounting equipment, providing flexible and rapid installation at customer sites.

Direct peers

• Hoondert Staalbouw: Hoondert Staalbouw is a custom structural steel fabricator based in Terneuzen, Netherlands, serving industrial and maritime clients with EXC-certified fabrication and assembly — a directly comparable mid-sized Dutch specialist steel contractor.
• IHC IQIP: IHC IQIP is a Dutch-founded specialist in offshore foundation and marine piling equipment (hydraulic hammers, vibro drivers, lifters). It overlaps directly with Boll's spud pole / marine positioning business and serves similar European offshore and dredging contractors, though it is a larger, more globally distributed player.
• Kooiman De Gilde: Kooiman De Gilde is a Dutch shipbuilding and steel fabrication contractor serving the inland-waterway and offshore market from Zwijndrecht. Its combined steel-and-marine equipment focus makes it one of the closest small-to-mid sized direct comparables to Boll.
• Alewijnse: Alewijnse is a Dutch marine electrical and automation systems integrator serving shipbuilders and offshore operators. It is comparable through its Dutch mid-sized maritime-customer footprint and engineering-driven custom-systems model, even though its discipline is electrical rather than mechanical fabrication.
• Victor Buyck Steel Construction: Victor Buyck is a Belgian custom steel fabricator for bridges, industrial buildings and architectural steelwork with EN 1090 EXC 3-4 certifications. Comparable to Boll on custom structural fabrication, certification level, and project-based delivery into Benelux heavy-construction markets.
• Bakker Sliedrecht: Bakker Sliedrecht is a Dutch marine-electrical and automation specialist that designs and integrates custom systems for Dutch shipyards including winch-control and positioning systems. It is comparable on engineering-driven, project-based, Dutch maritime-systems deliveries.

Broad incumbents

• Damen Shipyards Group: Damen is the largest Dutch shipbuilder with a broad portfolio including workboats, tugs and specialized vessels that use spud poles and winches. While not a direct fabricator competitor, its scale and integrated equipment sourcing make it a broad incumbent reference point for Boll's maritime customer base.
• Royal IHC: Royal IHC is the largest Dutch builder of dredging vessels and integrated dredging equipment. It addresses many of the same Dutch and international maritime customers as Boll but at vastly greater scale and scope, including shipbuilding and turnkey dredging systems rather than focused fabrication.
• Hollandia Structures: Hollandia (part of VDL Groep) is one of the largest Dutch structural steel fabricators for bridges, lock gates, and large industrial structures. It is EN 1090-certified and operates in overlapping infrastructure verticals to Boll's steel-construction arm but at significantly larger scale.
• Mammoet: Mammoet is a Dutch heavy lifting and transport specialist with deep overlap to large maritime, dredging and infrastructure customers that Boll serves. It is a vastly larger broad incumbent whose customer list includes many of the same dredging and civil contractors.
