Lead story: IFC, IDS, and BCF solve different BIM exchange problems

buildingSMART publishes IFC model schemas, IDS requirement artifacts, and BCF collaboration formats as distinct standards families. A project should select from the governed object and workflow, then name the exact version, status, participants, and acceptance evidence.

Procore visual comparisons need action-authority lineage

Procore's September 9 acquisition announcement says DroneDeploy can capture jobsites with drones, robots, and cameras while Procore AI compares visual data with BIM and schedule records and surfaces action. Project teams still need the exact capture, comparison method, exception, reviewer, contract role, authorized action, and later result.

ALICE scenario selection needs objective-and-constraint lineage

ALICE describes importing a P6 or Microsoft Project schedule or a BIM model, setting optimization goals and constraints, generating alternatives on a time-cost graph, and selecting or exporting a solution. The chosen scenario still needs a record that explains its inputs, trade-off, authority, schedule promotion, and later variance.

OSHA competent-person authority must be task specific

OSHA 1926.32 defines a competent person by both hazard-recognition capability and authorization to take prompt corrective measures. A contractor should connect the named person to the actual task, applicable standard, site and shift, evidence of knowledge, corrective authority, observations, actions and escalation.

Jonas service work needs a service-to-job-cost boundary

Jonas presents construction and service management software connected with accounting and operations. A service call may relate to an original project, asset, warranty, or new commercial request, but dispatch, work completion, customer acceptance, job cost, invoice, and cash remain separate records; the system needs an explicit boundary before either service or project reporting can be trusted.

SmartPM schedule KPIs need calculation lineage

SmartPM presents schedule health, quality, compression, SPI, and predicted-completion indicators. Each KPI still needs the exact imported schedule version, status date, definition, calculation, denominator, exclusions, and method version that produced it.

How the market is organized

Project information

A current document is not automatically an authorized instruction

Useful project systems preserve originator, revision, status, distribution, response, contract role, effective date, supersession, downstream action, and retained evidence—not merely the newest file.

Cost and change

A change log is not the same as an approved commercial position

Commercial control connects notice, scope, cause, responsibility, quantity, price, time, status, authority, contingency, forecast, accounting, and payment while preserving disputed and pending exposure.

Schedule and production

A percent complete is not a schedule diagnosis

A defensible schedule record needs the approved baseline, current data date, logic, calendars, constraints, progress method, resource assumptions, changes, uncertainty, and accountable update process.

Read the market record →
Field evidence

A closed task does not establish accepted installed work

Field evidence connects current plans, location, crew, conditions, work performed, inspection, issue, correction, acceptance, quantity, downstream record, and the people authorized to make each decision.
