Gnosis

Gnosis is a contract administration assistant designed specifically for the civil engineering and construction sectors. It streamlines the management of contracts by integrating various essential functions into a unified system, ensuring compliance with standard forms such as NZS 3910, AS 4000, and AIA/EJCDC. This integration allows professionals to handle claims, certificates, variations, notices, and statutory deadlines efficiently, reducing the reliance on disparate tools like spreadsheets and email threads. One of the core features of Gnosis is its ability to process payment claims. Contractors can submit claims directly through the platform, which then aligns these claims against the predefined Schedule of Rates. The system automatically calculates cumulative quantities, applies retention bands, and computes GST according to the specific contract's rulebook. Any discrepancies, such as over-claims, are flagged with supporting evidence, facilitating accurate and transparent certification processes. Gnosis also manages variations and extensions of time (EOT). Users can raise Variation Orders, tag relevant clauses, and price them against scheduled rates. The platform routes these variations through predefined approval chains, ensuring that all changes are authorized appropriately. Additionally, granted EOTs adjust downstream project timelines automatically, maintaining an up-to-date project schedule. The communications hub within Gnosis consolidates all project-related communications, including notices, Requests for Information (RFIs), Non-Conformance Reports (NCRs), and transmittals. Each communication is numbered, role-tagged, and tracked with statutory clocks, ensuring timely responses and a comprehensive audit trail. Gnosis Intelligence, the platform's AI-driven component, enhances various aspects of contract administration. It assists in importing and structuring schedules of rates from spreadsheets, drafting documents, and flagging potential issues. Importantly, all AI-generated drafts require human approval before issuance, maintaining professional oversight and accountability. The platform supports subcontract and supplier management by providing free portals for subcontractors. These portals are scoped to individual subcontracts, allowing subcontractors to submit claims and view their records without accessing unrelated project information. This ensures data security and clarity in subcontractor interactions. Gnosis offers flexible pricing plans tailored to different organizational needs. The 'Practice' plan is designed for sole practitioners or small teams, including two active contracts and three team members. The 'Firm' plan caters to consultancies and contractors managing multiple projects, offering ten active contracts and unlimited team members. The 'Agency' plan is customized for larger entities like state agencies or multi-office firms, providing unlimited contracts and additional features such as Single Sign-On (SSO) and data residency options. In summary, Gnosis provides a comprehensive, integrated solution for contract administration in the civil engineering and construction industries. By automating critical processes and ensuring compliance with standard contract forms, it enhances efficiency, accuracy, and accountability in project management.

GremIA

GremIA es un software de gestión para empresas de reformas y pequeñas constructoras de 8 a 30 trabajadores que llevan varias obras abiertas a la vez y tienen a alguien en oficina. Sirve para saber qué obra gana dinero y cuál se come el margen. En muchas de estas empresas el presupuesto vive en un Excel, los partes llegan por WhatsApp y las facturas se guardan en una carpeta. Hasta que la obra se cierra, nadie sabe si ha dejado dinero. GremIA junta todo eso en la ficha de cada obra: presupuesto, partes, compras, horas y cobros. El gerente ve el margen mientras la obra sigue abierta, cuando todavía puede corregir. Los presupuestos se preparan con IA a partir del WhatsApp o las notas del cliente. Las obras se llevan con planificación y partes diarios con fotos, y el personal ficha y apunta sus horas desde la app móvil. Las facturas y albaranes de proveedor se leen con OCR y se imputan a su obra. Un radar diario ordena las prioridades, los avisos y las acciones recomendadas. Los informes muestran rentabilidad, cobros pendientes, costes y margen. También incluye portal del cliente y control de herramientas y almacén. Obrasur, empresa de reformas de Huelva, pasó del 12-18 % a cerca del 30 % de rendimiento neto en menos de 4 meses con GremIA. Hay tres planes mensuales: Equipo (99 €), con 5 usuarios de oficina y 10 de obra; Multiobra (199 €), con usuarios ilimitados; y Pro IA (399 €), con IA sin límites y soporte preferente. La prueba dura 7 días y no pide tarjeta. GremIA no está pensado para el autónomo que lleva una sola obra a la vez.

I-Cost

I-Cost is a construction commercial and carbon management platform for UK contractors, estimators and quantity surveyors. Import a client's BOQ from Excel or CSV and turn it into a structured estimate with areas, levels and sub codes, cost and selling rates and target margins. Lock the final estimate for tender and keep revisions under control. From the estimate, send requests for quotation to suppliers, compare their prices side by side and issue numbered purchase orders with delivery notes, invoices and certificates attached. Staff and site operatives log their hours against the same estimate items, with weekly approval. Every estimate line can carry an embodied-carbon factor from the UK ICE database or your own EPD factors, so cost and carbon are measured on the same quantities. Project reports compare estimate against actual cost by area and export to PDF, Word and Excel. Construction-specific roles, project-level access and granular permissions keep the right information with the right people.

IVO Systems

IVO Systems is easy-to-use, modular, field-first construction operations software for heavy civil contractors running site-based, self-perform work. The platform connects crews, equipment, jobs, and operational information across the field, shop, and office. Designed for earthwork, underground utilities, roadbuilding, site development, and other equipment-intensive work, IVO lets contractors choose the tools that fit their operations while keeping information connected across the business. Company-wide access is included without seat-based licensing, and custom permissions control what each person can see and manage. Connected workflows help teams replace separate spreadsheets, whiteboards, paper forms, phone calls, and disconnected systems. Connections with OEM and third-party telematics providers bring mixed-fleet data into one system. Integrations with ERP and accounting platforms, including Vista, Spectrum, Foundation, Sage 100 Contractor, and Sage 300 CRE, help reduce duplicate entry across operations, accounting, and payroll. IVO Systems was founded in Wisconsin in 2019 by Eric Christensen after more than a decade working in heavy civil construction. He left his role at a large contractor to build the operations platform he wished he had. That experience continues to shape software that improves visibility and connects field, shop, and office teams without disrupting established workflows. Available modules include: TimeVO - Auto-populated field employee and crew timecards IntegrationsVO - ERP and accounting platform connections TrackVO - Online magnet board for equipment locations and job information DispatchVO - Equipment-move scheduling and digital dispatch tickets, with text and email notifications TelematicsVO - Unified OEM and third-party GPS and telematics data MaintainVO+ - Preventive maintenance, work orders, alerts, equipment history, and mechanic timecards EqInspectVO - Custom equipment inspection forms with alerts and work-order creation ScheduleVO - Employee and crew scheduling with interactive text messages and verified receipt EqPlannerVO - Gantt-chart equipment and resource planning RentalVO - Rental equipment tracking and cost management UtilityLocateVO - Utility locate and 811 ticket management and documentation Benefits of IVO Systems include: Clearer equipment visibility - View owned equipment, rentals, attachments, inventory, and mixed-fleet telematics information in one system.

More organized scheduling and dispatch - Centralized crew schedules, equipment availability, interactive text updates, and digital dispatch tickets help reduce mistakes, confusion, and unnecessary equipment moves. Cleaner timecard and payroll information - Field-entered digital timecards, validation, assigned cost codes, approval permissions, and ERP exports help reduce missing information, payroll corrections, reformatting, and duplicate entry while improving real-time job-cost visibility. More proactive maintenance - Usage-based preventive maintenance, automatic meter updates, digital inspections, work orders, and equipment history help shop teams identify issues earlier and schedule service. Faster field communication - Mobile access and interactive text messages give employees clearer assignments and current information while reducing individual phone calls.

Klorra AI

Klorra AI is an AI estimating service for custom home builders. Upload an architectural plan PDF; typically in about 4 hours you get back a complete bid you can put in front of a client. Five documents, each viewable in the app and downloadable as Excel or Word: - Quantity takeoff: 400+ measured quantities organized by trade, each cited to its plan sheet. - Cost estimate: line items across 160+ cost codes, calibrated by region. - Scope of work: organized by trade in build order, tied to the estimate line items so the two don't drift. - Conflict report: cross-discipline clashes, code issues, and items that need an architect or engineer to clarify. - Verification notes: what a second-agent QC pass flagged for you to confirm before the bid goes out. How it works: a 7-phase pipeline (Plan Intelligence, Conflict & Issue Review, Building Data Takeoff, Cost Detail Generation, QC Review, Scope of Work Generation, Delivery), every phase on the current Claude Opus model. Fully AI from intake through delivery. The QC phase is an audit whose findings ship to you as the verification notes; it is not a guarantee. Who built it: an active Naples, FL custom home builder that needed it for its own bids. The same pipeline runs our own bids today. We opened it to other builders in 2026. What we're honest about: AI still gets things wrong on custom roof geometry, missing structural pages, hand-marked plan edits, and MEP conflicts that don't show on any single sheet. Klorra flags those so estimators know where to focus their effors. The accuracy disclaimer is in plain English in our terms, and you verify every quantity against your own takeoff before commercial use. Pricing: $299 per bid pay-as-you-go, first bid free with no card. Builder $2,990/yr (14 bids), Pro $8,990/yr (66), Studio $24,990/yr (200); monthly plans available. Annual saves 25%. Serving custom home builders in Florida, North Carolina, South Carolina, and Texas at launch. A complete sample bid is public at klorra.ai/samples, no signup.

KNTRCTR

KNTRCTR is subcontractor bid management software for prime contractors (general contractors) in heavy civil and general construction, with Rex AI, a bid intelligence assistant, built into the job itself. The job runs from scoping through invites, bids, comparison, award, kickoff, and a locked performance review. Rex AI sits on that job the whole way instead of in a separate window somebody has to remember to open. You decide what gets compared: Before the job goes out, the prime optionally sets bid expectations: the exact scope items and budget lines every bidder has to answer to. Mobilization, traffic control, restoration, whatever the job actually turns on. That structure is what turns twelve quotes in twelve formats into one field you can read across. Rex AI helps the sub fill it in: Filling out somebody else's form is the part subs hate, so Rex AI does the first pass for them. A bidder who subscribes can upload their own quote and have Rex AI populate the prime's bid expectation rows from it, then check the finished bid against the original request before it goes. If traffic control was on the request and never made the draft, the sub finds out while there is still time to fix it, instead of getting a phone call about it two days later. Invited bidding is free either way. Rex AI for bidders is a leg up, not a requirement to bid. Rex AI fills it in for the prime when the sub skips it: Some bidders will skip the section. Some will email a PDF and call it a day. Rex AI reads that attachment and fills the same bid expectation rows on the prime's side, so the column gets completed rather than left blank. You end up comparing complete columns either way. Then Rex AI reads the field against what you asked for: Stage 1 is a field scan. Every bid measured against the bid expectations you set, not against a generic checklist: pricing outliers, scope coverage gaps, unanswered lines, budget alignment, and what the attached files actually say, in one structured read. Stage 2 is a deep read of one company. Rex AI goes into that bidder's attachments and pulls the detail behind the number. Run all of your bids through this deep dive to get the full review. This is where the money usually hides. A bid that looks low is often a bid that left mobilization out of the total. Rex AI puts the exclusion on the screen before that number does any heavy lifting. Ask Rex AI about this job: Rex AI chat stays on the job in front of you. Ask why one number sits well under the rest, what a file says, whether a scope item ever got answered, or how a company performed the last time you used them. Answers come from this job's request, bids, files, and performance record. Not from a blank page. Rex AI analyzes. You decide. No auto award, no ranked winner handed down. The rest of the platform: Private lists and invites for your go to crews. Open job posts when you need coverage on a trade. Bid intent tracking so you know who is submitting and who is passing before bid day. Bid leveling and bid adjustments that normalize pricing while every original number stays visible. Supplier quotes in the same comparison. Job kickoff with notes, checklist, and document handoff. Job discussion. Company profiles covering equipment, certifications, personnel, and past projects. Multi user access for estimating, procurement, project management, and field teams. Every job closes with a performance review that locks to the record. The next time that subcontractor comes up on a bid, their score sits beside their price. Scores are shared as scores, without written commentary. Who it is for: Prime contractors and general contractors running sewer and watermain, excavation, site servicing, hydrovac, asphalt, haulage, underground utilities, and general construction. Built for outfits carrying several estimators, a project management group, and multiple crews going at once.
