What it doesConstruction safety platform for subcontractor management, worker orientations, safety plans, permits, inspections, incidents and site access. Modules listed cover subcontractor management, worker orientations, JHAs, SDS, safety plans, pre-task plans, permits, safety meetings, logistics, equipment compliance, inspections, observations, incidents, daily reports, and site access. Lists HammerTech Intelligence and promotes AI for safety. Vendor says it was built by former safety professionals; PCL is featured as a customer. Re-read Oct 18, 2026: the HammerTech Intelligence page says AI is embedded in SDS autofill, pre-task plan meeting capture, observation photo recognition and site diary summaries, drafts summaries and reports inside the workflow, and keeps every output transparent and editable, with people making the safety decisions. Its integrations page lists HammerTech Sync for Procore (projects, subcontractors and locations in; labor hours and worker counts out to the Procore Daily Log), Autodesk project and subcontractor sync, CMiC and Sage Intacct, facial recognition turnstiles, Eyrus, Kwant, Acumatica, LUMA1 and an open API. Re-read Oct 19, 2026: the Intelligence page lists the same four workflows and says the AI is trained on safety process context such as permits, hazards and inductions (vendor claim); the pricing page says HammerTech is built for commercial and infrastructure contractors managing multiple job sites. Re-checked Oct 21, 2026: homepage unchanged in substance (one safety platform for inductions, pre-starts, incidents and reporting; no per-seat fees; HammerTech Intelligence surfaces risks and automates safety reporting).

Pricing (as publicly stated)No paid prices listed (checked Oct 16, 2026; re-checked Oct 18 and Oct 19, 2026). The pricing page says HammerTech does not use per-user pricing (unlimited users); pricing is based on the scale and complexity of your operations, including annual construction volume and the number of active job sites, company size and the level of onboarding and support required, and all core workflows are included rather than sold as modules (implementation, onboarding, training, support, integrations and security included). Its FAQ says HammerTech is free for subcontractors, with access provided by the general contractor managing the project. The page says it is not the right fit for very small teams, single projects or basic checklists. GC pricing is tailored ("Get Pricing Details"). Confirm current pricing with the vendor. Re-checked Oct 21, 2026: still no prices. The pricing page now lists three factors: annual construction volume, company size and operational complexity, and level of onboarding and support required; the number of active job sites is no longer named. Unlimited users, all-in-one pricing (not modules) and the not-the-right-fit list are unchanged; the FAQ answers did not expand in our read. Re-checked Oct 22, 2026: unchanged (no dollar prices; priced on three factors with unlimited users; the FAQ names annual construction volume and the number of active job sites; free for subcontractors). Re-checked Oct 23, 2026: still no prices (no per-user pricing; priced on annual construction volume, active job sites, company size and operational complexity and the level of onboarding and support; all core workflows included; free for subcontractors with access provided by the GC). Re-checked Oct 24, 2026: unchanged (no per-user pricing; priced on annual construction volume, company size and operational complexity, and onboarding and support level; free for subcontractors; no modules sold separately). Re-checked Oct 25, 2026: unchanged (no per-user pricing; priced on annual construction volume, company size and operational complexity, and onboarding and support level; FAQ also names active job sites; free for subcontractors; not the right fit for very small teams or single projects).No public prices found (checked Oct 16, 2026; unchanged Oct 19, 2026, /pricing still not-found): the vendor site has no pricing or plans link in its navigation or footer, and /pricing and /plans return a not-found page. The site's calls to action include "Request a demo", "Talk to sales". Confirm current pricing with the vendor. Re-checked Oct 21, 2026: still no prices; calls to action are Schedule Demo, Request A Demo and Talk To Sales.

Where the vendor descriptions differ

  • What each watches: HammerTech's modules cover subcontractor management, orientations and worker info, JHAs, SDS, safety plans, pre-task plans, permits, safety meetings, logistics, equipment compliance, inspections, observations, incidents and injuries, daily reports and site access. viAct's scenarios cover PPE detection, danger-zone alerts, work at height, confined space, fleet management and environmental monitoring, with a dashboard for progress monitoring.
  • Where the AI sits: HammerTech Intelligence is embedded in SDS, pre-task plans, observations and site diaries, drafts summaries and reports for review inside the workflow, and says people make the safety decisions. viAct's AI is proprietary scenario-based computer vision on CCTV feeds that raises real-time alerts; its menu also lists viGENT (agentic AI) and generative AI solutions (not reviewed).
  • Hardware: HammerTech is software, with facial recognition turnstiles for site access through its integrations page. viAct lists its own hardware lines (smart watch and smart helmet wearables, lidar, drone, hoisting, machinery and robotic units, weather station, gas leak detector) and site systems such as permit to work, a 4S Smart Site Safety System, a Digital Works Supervision System (DWSS) and a Project Control Center.
  • Integrations: HammerTech lists HammerTech Sync for Procore (projects, subcontractors and locations in; labor hours and worker counts out to the Procore Daily Log), Autodesk project and subcontractor sync, CMiC, Sage Intacct, Acumatica, Eyrus, Kwant, LUMA1 and an open API. viAct describes plug-and-play integration with existing cameras but names no software integrations on its homepage.
  • Pricing (checked Oct 25, 2026): neither publishes figures. HammerTech says it does not price per user, prices on annual construction volume, company size and operational complexity and onboarding level, includes all core workflows, and is free for subcontractors (access through the GC); its pricing page says it is not the right fit for very small teams or single projects. viAct's /pricing returns not found; it routes to Request A Demo and Talk To Sales.
  • Not like-for-like: some contractors run both kinds of tool, a safety system of record plus camera alerts. Neither vendor's pages describe an integration between the two.
  • Not used here: HammerTech's customer counts and quotes, and viAct's accident, fatality, manpower-cost and productivity percentages, award claims and client quotes (vendor content).

What users say

The facts above come from vendor websites. Whether either tool is any good for your work is something only people who use them can say. These are member reviews, all ratings shown, never edited or removed for being negative.

Good or bad, an honest review from an estimator, PM or super helps the next team more than another vendor demo. You post under a handle; your email is never shown.

Questions to ask in your review

  • How viAct alerts would reach a safety system of record such as HammerTech; no integration is named
  • How well viAct's detections work on US jobsites; the vendor is based in Hong Kong and its homepage quotes MTR Corporation
  • What you actually pay, and on what basis (neither publishes full prices)
  • What did you use it for, on what kind of work and project size?
  • How long did setup and training take, and who on your team did it?
  • What does it cost you in practice, compared with what the sales call said?
