Does FDZ design crane foundations?

No. FDZ installs crane foundations per approved engineered drawings. Foundation design, anchor bolt specification, and bearing capacity determination are the structural engineer's scope. We install what the engineer draws.

Who provides the anchor bolt template?

The crane supplier provides anchor bolt shop drawings with bolt pattern, diameter, projection, and template layout. FDZ installs per those drawings — coordinating with the crane supplier and GC before the pour.

How do you handle OKC's clay soil under crane foundations?

We evaluate sub-base conditions after excavation and report unsuitable material to the GC and structural engineer before proceeding. OKC's expansive clay often requires over-excavation and engineered fill under high-load foundations — skipping this step causes differential settlement under point loads.

Can you coordinate with our structural engineer and GC?

Yes. Coordination with the GC, structural engineer, and crane supplier is part of every crane foundation pour we run. We confirm drawings, anchor bolt templates, and pour sequence before mobilizing.

What concrete PSI is required for crane foundations?

Concrete PSI is specified by the structural engineer in the drawings — typically 4,000–5,000 PSI for crane foundations. FDZ orders per spec and provides batch tickets for documentation.

Do you provide sub-contractor documentation for GC bid packages?

Yes. COI and bonding documentation available as part of the bid process. We work as concrete sub-contractors on GC-managed commercial projects.

Crane Foundation Installation in Oklahoma City, OK

Crane foundations installed per approved plans — anchor bolt and embed coordination, reinforcement placed per plan/spec, and full coordination with the GC, engineer, crane provider, and owner. (405) 458-4805.

Crane foundations carry some of the highest point loads of any concrete work on a commercial site. The concrete scope — excavation, forming, reinforcement placement, anchor bolt layout, and pour — must be executed exactly per engineered drawings. FDZ Construction handles the concrete installation scope for crane foundations across the Oklahoma City metro: reinforcement placed per plan/spec, anchor bolts and embeds coordinated directly with the crane supplier and engineer, and pour sequencing coordinated with the GC. We install per approved plans — we do not engineer or design crane foundations. Call (405) 458-4805 to discuss scope and scheduling.

Oklahoma City Conditions

Oklahoma City's expansive Permian-age clay requires deeper sub-base excavation under crane foundations than most other markets. The clay's swell-shrink cycle under heavy point loads causes differential settlement without proper sub-base correction and drainage. Every crane foundation we install includes sub-base evaluation and drainage detailing — not just the pour itself.

Commercial Services

Crane Foundation Pour — Concrete pour per engineered drawings — forming, reinforcement placement, and pour sequenced with crane supplier and GC. Not a design service — installed per approved plans.
Anchor Bolt & Embed Coordination — Anchor bolt templates and embed plates coordinated directly with crane supplier and structural engineer before any concrete is placed. No field improvisation on bolt pattern.
Reinforcement Placement Per Spec — Rebar schedule placed per structural drawings — bar size, spacing, and cover specified by the engineer of record. FDZ places per the drawings, period.
Sub-Base Evaluation & Preparation — Excavation, sub-base evaluation, and correction before any forming begins. OKC clay requires specific sub-base treatment under high-load foundations.
Pedestal & Elevated Foundation Pours — Above-grade pedestals and elevated foundation pours for overhead crane rails — formed, reinforced, and poured to the structural engineer's drawings.
GC & Trade Coordination — Coordination with GC, owner, structural engineer, and crane supplier from scope review through anchor bolt final. Available for pre-bid scope review.

Crane Foundation Concrete Scope

Foundation Excavation & Sub-Base

Excavation per engineered drawings — depth and bearing elevation per geotechnical report
Sub-base assessment after excavation — soft or unsuitable material removed and replaced
Compacted aggregate or lean concrete mud mat per spec before reinforcement
Drainage detailing around foundation per drawings
OKC clay sub-base often requires over-excavation and engineered fill — we evaluate and report to the GC and engineer

Forming & Reinforcement

Forms set per drawing dimensions — elevation and orientation confirmed with GC and crane supplier
Reinforcement placed per structural drawings — bar size, spacing, concrete cover, and lap splice locations per spec
Anchor bolt templates and embed plates installed per crane supplier shop drawings before pour
Utility conduit and grout sleeves placed per drawings
Rebar inspection coordination with GC and special inspector before pour authorization

Concrete Pour & Finishing

Concrete mix per spec — PSI and admixtures per structural drawings (typically 4,000–5,000 PSI)
Pour sequencing coordinated with GC to avoid interference with other trades
Top of foundation finished to tolerance required for base plate bearing
Cure per spec — minimum cure time before any load or anchor bolt tensioning
Final elevation and anchor bolt location survey available for owner and crane installer

Crane Foundation Sequence

Scope Review — Review engineered drawings with GC and crane supplier before any work begins. Confirm anchor bolt template, embed locations, concrete spec, and pour sequence.
Excavation & Sub-Base — Excavate to bearing elevation per drawings. Evaluate sub-base and report any unsuitable material to GC and engineer. Correct before proceeding.
Forming & Reinforcement — Set forms to drawing dimensions. Place reinforcement per structural drawings. Install anchor bolt templates and embeds from crane supplier shop drawings.
Inspection & Pour — Coordinate with special inspector before pour. Pour per spec PSI and sequence. Finish to bearing tolerance. Cure per spec.
Survey & Handoff — Final elevation and anchor bolt location confirmed. Foundation turned over to GC and crane installer per project closeout sequence.

Specifications

Concrete PSI: Per structural drawings — typically 4,000–5,000 PSI
Reinforcement: Placed per structural engineer's drawings and details
Anchor Bolts: Per crane supplier shop drawings — coordinated before pour
Sub-Base: Evaluated after excavation — corrected before forming
Cure Time: Per structural spec — no loading before specified strength
Tolerances: Bearing surface finished to spec for base plate bearing

What FDZ Does and Does Not Do

FDZ Construction installs crane foundations per approved engineered drawings. We do not design crane foundations, specify anchor bolt patterns, or determine bearing capacity — that is the structural engineer's scope. We install what the engineer draws.

Anchor bolt placement comes from the crane supplier's shop drawings — we do not improvise field bolt locations. If drawings are not available, we will not place anchors until they are. This is the only correct approach for a crane foundation.
