What g kracht does

G-kracht is a Dutch construction consortium that renews urban quay walls using a vibration-free method, primarily serving municipal clients in historic inner-city canal districts. Founded in 2019 as a joint venture of Aannemingsmaatschappij Van Gelder (a Dutch family-owned infrastructure group with 2,000+ colleagues), Gebr. De Koning (a 125-year-old geotechnical and hydraulic specialist with 130 employees), and Giken Europe (the European subsidiary of Japan's Giken Ltd., founded 1967), the company was established to respond to the Municipality of Amsterdam's Innovatiepartnerschap Kademuren (IPK) tender. The consortium emerged as one of three winners in 2020 and signed a 4–8 year framework contract with Gemeente Amsterdam on 21 April 2024.

The company's core product is the Gyropress™ Method, a vibration-free tube pile drilling technique licensed from Giken Europe. The method drills Ø 500 mm steel pipe piles to ~14 m depth through the existing quay wall, places smaller Ø 273 mm pipe piles at 750 mm spacing down to the canal bed, and finishes with precast concrete elements clad in cast-in-place masonry bricks that match historic appearance. Equipment travels over the installed piles, eliminating the need for a construction pit and allowing the adjacent road and waterway to remain open. The technique preserves trees (segmented drilling under crowns at ≥1.30 m clearance), halves the MKI environmental cost indicator (16,000 vs. 32,000 for traditional quay walls), and can be executed fully emission-free with electric equipment.

G-kracht derives revenue exclusively from public infrastructure contracts, awarded through public tender under the IPK framework. Pricing is project-based and negotiated within the framework agreement, with no published rate cards. The portfolio comprises 8 projects totaling ~1,035 meters across Amsterdam and The Hague. The go-to-market is enterprise field sales driven by public procurement visibility, relationship management with municipal decision-makers, and industry event participation (Platform BIKA). Customer segments include municipalities (primary), public and private quay owners (housing associations, water boards, private owners), and engineering offices involved in design and oversight. The organization is small (~16 named team members) and operates with the project resourcing, equipment, and technical backing of its three parent organizations.

Scale indicators6 records

Recent moves8 records

Expansion highlights6 records

Emerging players

• Keller Group: Global geotechnical contractor specialising in ground improvement and foundation solutions, including vibration-sensitive techniques. Comparable as a large specialist piling/foundation peer, though operating at a broader international scale than G-kracht.
• Bachy Soletanche: International geotechnical and foundation engineering specialist (Vinci subsidiary) with growing activity in low-vibration piling techniques. Comparable in piling/foundation technology domain though focused more broadly than heritage quay renewal.

Broad incumbents

• Koninklijke Volker Stevin (VolkerWessels): Large Dutch construction group with deep involvement in Dutch water, civil, and infrastructure projects. Comparable as a broad incumbent competitor for Dutch municipal infrastructure tenders, including quay and waterfront works.
• Ballast Nedam: Established Dutch construction and infrastructure firm active in civil, water, and mobility projects. Comparable Dutch municipal client base and ability to bid for quay/infrastructure renewal contracts alongside G-kracht's shareholder-parents.
• Royal BAM Group: Major Dutch/UK listed construction group with extensive civil engineering and infrastructure divisions. Comparable as a major Dutch public-sector infrastructure contractor with capability across quay, bridge, and water-related works.
• Strukton Civiel: Dutch civil engineering and infrastructure specialist within the Strukton group, active in foundation, water, and heritage infrastructure projects. Overlapping Dutch municipal client base and comparable civil construction capabilities.
• Heijmans: Large Dutch listed contractor (c.5,000 employees) operating across civil infrastructure, housing, and public space. Comparable client base (Dutch municipalities) and overlapping civil-engineering scope, though Heijmans does not specialise in vibration-free quay renewal.

Direct peers

• Gebr. De Koning: One of G-kracht's three shareholder-parents, a 125-year-old Dutch foundation and geotechnical contractor (130 employees). It is both an internal JV partner and an external peer executing quay wall and foundation works for the same Dutch municipal clients using conventional methods.
• Van Gelder Group: A second shareholder-parent of G-kracht; a 100+ year-old Dutch family-owned infrastructure contractor with 2,000+ employees executing civil, underground, and water infrastructure projects for Dutch municipalities — directly comparable client base and project type.
• Giken Europe: The third shareholder-parent and licensor of the Gyropress™ technology. Giken manufactures the static-press piling equipment G-kracht deploys and competes/operates in adjacent European markets, making it the closest technical comparator despite its equipment-supplier role.
