Assignar vs HCSS HeavyJob

Two field-operations platforms for self-perform civil contractors, aimed at the same crews and foremen from different angles (our reading). Assignar leads with scheduling people and equipment together, timesheets and dockets, plant prestarts, compliance and pay rules, and now pitches itself as a margin control platform, with Milo, an AI assistant that answers from your contracts and bargaining agreements. HCSS HeavyJob leads with time cards, quantities, job costing and daily field reports tied back to HeavyBid estimates, with an AI assistant included in current subscriptions and agents coming. Desk research from vendor pages read Oct 24, 2026; not tested, no winner.

What it doesField-operations platform for civil and specialty contractors covering people and equipment scheduling, timesheets, forms and compliance. It offers drag-and-drop scheduling of people and equipment on the same job, timesheets and dockets from the field, digital forms, plant prestarts and defects, compliance tracking (tickets, licenses, orientations, expiry alerts), geo-location on timesheet/form submission, reporting, and ERP/accounting integrations. Homepage targets asphalt, concrete, drilling, piling, excavation, earthworks, rail, scaffolding, crane, demolition, traffic management and more, and cites 800+ customers. Workforce-management pages describe matching skills to tasks, predicting limited resources, and managing subcontractor licenses. Pricing page says pricing is tailored / custom quote with a test drive via demo; the pages we read on Oct 16, 2026 did not describe generative AI. Re-checked Oct 19, 2026: the navigation now includes an AI Construction Expert page introducing Milo, an assistant in Assignar Pay that answers plain-English questions from your uploaded contracts, enterprise bargaining agreements (EBAs), tickets and dockets and shows the source clause (the page's examples: when a shift triggers overtime, or which clause supports a variation). Because Milo sits inside the established Assignar platform, we now tag it AI features added. The 800+ customers figure is unchanged (vendor claim). Re-checked Oct 20, 2026: the homepage calls Assignar a construction operations margin control platform and describes live job margin against the bid budget, award, bargaining agreement and plant hire rates (wet, dry, standby and travel) applied automatically with payroll and invoicing from the same record, and unbilled work and open variations surfaced while the job runs; the menu lists Assignar Pay, Assignar Operations, Milo, CraneOps, InfraOps and TrafficOps. The Milo page is unchanged in substance. Re-checked Oct 22, 2026: homepage and Milo page unchanged in substance (margin control platform for civil contractors; live job margin against the bid budget; award, bargaining agreement and plant hire rates applied automatically, with payroll and invoicing from the same record; Milo answering from uploaded contracts, EBAs, tickets and dockets with the source shown). The homepage lists trades including asphalt, concrete, drilling, piling, excavation, earthworks, non-destructive digging, rail, scaffolding, crane, demolition and traffic management. The 800+ contractors line and customer quotes are vendor material and not used. Re-checked Oct 24, 2026: unchanged in substance (margin-control positioning, Milo answering from uploaded contracts and agreements in Assignar Pay, CraneOps, InfraOps and TrafficOps). The crew scheduling page says over 600 contractors schedule with Assignar while the homepage says 800+; neither figure is used here.Field data and job-cost software for self-perform civil, infrastructure and utility contractors: time cards, production and dailies. Features listed: digital time cards, quantity/production tracking, job costing and budget forecasting, material tracking, map view, T&M billing, bulk work-order import, pay items, daily field reports (DFR) with customizable templates and inspector/owner sign-off, a daily log for management review of activities, photos and progress, custom construction forms, and payroll/accounting export (Sage, Viewpoint, QuickBooks named). Works offline and syncs later. The page says production data feeds back to HeavyBid for future bids, and that most customers are operational within 90 days. Figures on the page (4,000+ contractors, 128,000 active users, "95% of HeavyJob projects close within budget") are vendor claims. The product page we read Oct 16, 2026 does not describe AI features. Re-checked Oct 19, 2026: HCSS's AI page says the HCSS AI assistant, which HCSS calls the first natural-language AI assistant built for civil construction, is active and included in current subscriptions. In HeavyJob it answers questions about job costs, crew, equipment, budget performance and job variance, can generate charts, searches and navigates the platform, answers questions about uploaded SOPs, contracts and safety documents, and condenses days of HeavyJob daily digest data into a short narrative. HCSS says answers are grounded in your own data with sources, existing permissions apply, your data is not used to train AI models, and a privacy mode deletes questions and responses after each session. HCSS AI Studio and pre-built agents (a production analyst for over-budget cost codes, an estimate builder and a voice-driven field agent that drafts daily reports) are marked Coming Fall 2026, in beta first and then a paid upgrade. Because this AI is added to the established product, we now tag HeavyJob AI features added. Re-checked Oct 20, 2026: the product page feature list, offline capture with later sync, payroll and accounting export and the within-90-days rollout statement are unchanged, and it adds a dedicated implementation specialist per customer; the over-40,000-crews figure recorded Oct 19 no longer appears on the product page, so it is dropped here. HCSS's AI page still says the assistant is included in current subscriptions and that AI Studio and the pre-built agents arrive in beta later this year and then become a paid upgrade; it now also lists HCSS AI Core, a data foundation across the platform, as Coming Fall 2026, and says confidence scores show where the AI is and is not certain, with every output open to review and override. Re-checked Oct 22, 2026: the product page is unchanged in substance (time cards, production, job costing, DFR, daily log, forms, pay items, offline capture with later sync, Sage, Viewpoint and QuickBooks export, a dedicated implementation specialist, most customers operational within 90 days). HCSS's AI page is unchanged in substance: the assistant is included in current subscriptions; AI Core, AI Studio and the production analyst, estimate builder and field agents are Coming Fall 2026, in beta first and then a paid upgrade; it adds that nothing the agents prepare finalizes without the user's approval, and repeats that data is never used to train AI models and that HeavyJob permissions apply. The contractor count and support quotes are vendor material and not used. Re-checked Oct 24, 2026: the product page is unchanged in substance (Sage, Viewpoint and QuickBooks export, a dedicated implementation specialist, most customers fully operational within 90 days). HCSS's AI page is unchanged in substance: the assistant is active and included in current subscriptions; AI Core and AI Studio are Coming Fall 2026, with the production analyst, estimate builder and field agents in beta later this year and then a paid upgrade; nothing finalizes without the user's approval and confidence scores flag uncertainty; data is isolated to each company and not used to train AI models, and a privacy mode deletes questions and responses after each session (vendor statements).

Where the vendor descriptions differ

  • Scheduling vs job costing (vendor pages): Assignar's crew scheduling page describes drag-and-drop allocation of workers, crews and equipment in a timeline by availability and qualifications, bulk scheduling with recommendations and role-based assignments, job confirmations from the field and schedule changes from the mobile app. HeavyJob's product page lists time cards for crew hours, equipment hours and quantities, job costing and budget forecasting, material tracking, T&M billing, bulk work-order import, pay items, daily field reports with inspector or owner sign-off, a daily log, construction forms and payroll export. Each covers some of the other's ground; the pages we read put the weight in different places.
  • Equipment and pay rules: Assignar says it schedules machines and operators together, logs plant prestarts and defects against the asset, shows idle plant and standby hours, and applies award, bargaining agreement and plant hire rates (wet, dry, standby and travel) automatically so payroll and invoicing come off the same record. HeavyJob tracks equipment hours on time cards and exports approved time cards to payroll and accounting (Sage, Viewpoint and QuickBooks named); HCSS lists Equipment360 and HCSS Telematics as separate products.
  • Where the AI sits: Assignar's Milo, in Assignar Pay, answers plain-English questions from your uploaded contracts, EBAs, tickets and dockets and shows the source clause (examples on the page: when a shift triggers overtime, which clause supports a variation). HCSS says its AI assistant is active in current subscriptions and in HeavyJob answers questions about job costs, crew, equipment, budget performance and variance, generates charts, answers questions about uploaded SOPs, contracts and safety documents and condenses daily digest data into a short narrative; HCSS AI Studio and pre-built agents (production analyst, estimate builder and a voice-driven field agent that drafts daily reports) are marked Coming Fall 2026, in beta first and then a paid upgrade. HCSS says your data is not used to train AI models and existing permissions apply.
  • Estimating loop and fit: HCSS says HeavyJob production data feeds back into HeavyBid for future bids, and HeavyJob is aimed at self-performing civil, infrastructure and utility contractors. Assignar says actual unit costs from finished jobs become the numbers you bid the next one with, and lists industries including heavy civil, excavation, asphalt and paving, concrete, rail, infrastructure, scaffolding, crane and rigging, demolition and traffic, with sales in Australia, New Zealand, North America and EMEA.
  • Pricing (checked Oct 24, 2026): neither publishes prices. Assignar's pricing page says pricing is tailored to your team with a custom quote through a demo and a test drive. HeavyJob routes to Get pricing and demo requests; HCSS says the AI assistant is included in current subscriptions and the coming agents will be a paid upgrade after beta. HeavyJob says most customers are operational within 90 days with a dedicated implementation specialist. Customer counts (Assignar's pages give both 800+ and over 600), HeavyJob's user count, within-budget percentage and rating, efficiency and time-saved figures, and customer quotes on both sites are vendor content and are not used here.
