For Architects + A&D
Firm-level stone specification, across every project.
For A&D firms managing stone specification across multi-project portfolios. Role-based workflows — senior architect approves, specification associate maintains, field staff verify on install. Project versioning per revision. Cross-portfolio queryability by stone, lot, supplier, fabricator, finish. Newforma, Procore, and Deltek sync on Enterprise tier.

The proposition
Firm-level institutional memory.
The senior partner who specified the marble for the lobby in 2018 retires. The associate who knew which lot it came from changes firms. The institutional memory of which stone-where-and-why disappears with them. Honed Earth holds the trail at the firm level, not the person level.
- Firm projects audit-trailed
- All
- Per-project specifications
- Versioned
- Cross-project lookup
- By stone, finish, supplier

The A&D workflow
Specify. Document. Reference forever.
01
Specify by lot, not by category
Construction documents call out the actual slab, lot, and finish. Substitution requires explicit re-spec — the trail prevents accidental drift.
02
Document in the project record
The firm's project record carries every slab specified, every fabricator engaged, every supplier ordered from. Six years from now, the new associate sees the full lineage.
03
Reference across the portfolio
Library of past specifications becomes a queryable knowledge base. 'Show me every lobby project where we used dolomitic marble' returns answers, not searches.
What you get
The firm's record, not the principal's memory.
Multi-team workflow
Project teams collaborate on stone specification with role-based access. Senior architect approves; specification associate maintains; field staff verify on install. Audit trail per role, per change.
Cross-project portfolio queryability
Firm-level dashboard surfaces which lots, suppliers, fabricators, and finishes have been used across the portfolio. Pattern recognition becomes a tool, not a tribal-knowledge problem.
Enterprise tier metrics
Multi-team, audit-aligned.

Common questions
What about…
Does this integrate with our existing project management?
Yes. API access on Enterprise tier allows linking Honed Earth specifications to your firm's PM system (e.g. Newforma, Procore, Deltek). Two-way sync available.
Can we share project-level access with clients?
Yes — read-only client access is configurable per project. Clients see the spec and the audit trail without seeing pricing or supplier-side data.
What about LEED or sustainable sourcing documentation?
Every Honed Earth listing carries supplier certifications and sourcing data. Export to LEED submission templates is a single-click action; documentation auto-attaches.
How does this affect construction administration?
Substitution requests run through the same audit trail. When a fabricator proposes a substitute lot, the firm's spec lead approves or rejects in-platform; the trail documents the decision.
The supply chain, in plain sight
Five categories. One ledger.
Suppliers, distributors, and fabricators manage their inventory of bundles, slabs, and remnants. The union of those inventories is the marketplace — searchable by the trade and by homeowners. From the quarry to the kitchen.

Suppliers
Manage inventory of bundles, slabs, and remnants. Lot tagging, photo signing, warehouse rack assignment.

Distributors
Inventory across multiple warehouses and supplier sources. Connection-only or public.

Fabricators
Source slabs, manage your shop's remnant inventory, surface bookmarks to designers.
