ENGINEERING THAT
PROTECTS YOUR MARGIN

Most structural problems on site come from the design stage. We eliminate them before they happen. Our BIM-first approach means clashes, coordination failures and specification gaps are caught in the model — not discovered when the crane is already on site.

Grey Gecko has been delivering precast concrete and steel structures since 2011. Every project follows one principle: a structure that is correctly engineered and genuinely buildable. Not over-engineered. Not under-specified. Right-sized for production and site.

We deliver structural packages for Skanska, Serneke, NCC, Nordecon and 12+ major Nordic and Baltic contractors. Our documentation is production-ready.

          
Fabrication-Ready BIM ModelsEvery element modelled to manufacturing tolerance. Tekla models transfer directly into precast production.

          
Responsive, Predictable DeliveryStructural packages delivered on programme, with clear scope and responsive coordination throughout.

          
Coordinated Before ConstructionStructure, MEP and architecture coordinated in the model so conflicts are resolved before work begins on site.

          
Material-Efficient StructuresStructural optimisation from concept stage reduces over-specification and construction waste.

02 / 07Our Services

WHAT WE
ACTUALLY DO

Frames sized for the loads they carry — not over-built, not under-built.

Reinforced concrete, precast and steel frames designed and detailed in Tekla.
Strip footings, raft slabs, pile caps and combined systems sized directly from the geotechnical report.
A senior engineer stays close to your project throughout.

Shop drawings precast factories use without rework.

Fabrication-grade precast element drawings and steel shop drawings — geometry, reinforcement, embeds, lifting points and connections issued straight to the factory and the erection team.
Tekla models are detailed to fabrication level — coordinated and ready for production.

From the structural design to NC files the fabricator loads straight into the machines.

Steel frames, trusses, platforms and stairs designed and detailed in Tekla Structures.
KM: analysis, general arrangement, connection design and specifications.
KMD: assembly and single-part drawings, DSTV NC and DXF files, material and bolt lists — issued in packages that follow the erection sequence.

Engineer-verified coordination of all discipline models — each issue goes to the designer who owns it.

We detect and resolve clashes between structure, MEP and architecture before they cost money on site.
We produce a fabrication-ready structural BIM model and coordinate it with the architecture and MEP teams through IFC exchange — so every discipline builds from one consistent structural geometry.
Federated IFC model, clash checks by discipline pair, BCF issues to each designer, BEP compliance check by our engineers and a weekly coordination report.

About the service →

Design expertise of the structural part in Estonia and independent review of structural design sets.

Drawings checked against the model, the calculation basis and each other — title blocks, revisions, notes, cross-references and references to standards.
Findings by sheet with marked-up copies, a readiness verdict and the cost drivers.
Software searches and cross-references; an engineer reviews and signs.
