What is Pelles?

Pelles is a cloud-based AI preconstruction platform built exclusively for mechanical, electrical, and plumbing (MEP) subcontractors that automates the document-intensive tasks consuming most of a preconstruction team's time — specification review, addenda comparison, RFI drafting, and submittal log generation. Its generative AI engine reads full bid packages including drawing sets and specification documents, extracts trade-specific requirements, and surfaces them with direct paragraph citations rather than requiring estimators to manually skim hundreds of pages under deadline pressure. For a typical MEP bid package — 300+ drawing sheets, a 600-page specification set, and addenda arriving days before the submission deadline — the manual review process is where scope gets missed and margin gets lost. Pelles' DoubleCheck feature scans the full specification set and surfaces trade-relevant clauses including warranty requirements, testing protocols, and equipment standards with exact page and paragraph citations. Its Compare feature processes new addenda the day they are released and produces a clean delta report flagging changed breaker sizes, revised VFD notes, updated panel schedules, and modified conduit specifications — giving estimators an immediate view of scope impact without cross-referencing documents manually. Pelles is not designed for general contractors or owner's representatives managing the full construction project lifecycle. Its feature set, user interface, and document intelligence model are calibrated specifically for trade subcontractor preconstruction workflows. Organizations outside the MEP sector — general civil contractors, structural subcontractors, or construction developers — will find the platform's scope too narrow for their project document management needs.

Pelles is an AI preconstruction tool built for MEP subcontractors that automates specification review, RFI generation, submittal logs, and addenda comparison using generative AI and PDF document intelligence.

Pelles is widely used by professionals, developers, marketers, and creators to enhance their daily work and improve efficiency.

Key Features

1

AI-Powered Preconstruction Tools

Pelles applies generative AI to full bid package document sets — drawings, specifications, and addenda — to automate quantity takeoff extraction, scope identification, and requirement analysis tasks that typically consume 60-80% of a preconstruction team's active time. Estimators receive structured outputs with page-level citations, enabling faster bid preparation without the risk of skimming requirements buried in Division 01 or cross-referenced specifications.

2

Customizable Workflows

The platform's document intelligence and output formatting are configurable to match each contractor's internal proposal structure, submittal log template, and RFI format — ensuring AI-generated documents meet general contractor submission requirements without post-processing reformatting. Customization is applied at the organization level and persists across all projects, reducing setup time for repeat bid configurations.

3

Cloud-Based Platform

Pelles operates as a cloud-based platform accessible from any browser without local software installation, enabling preconstruction teams to review bid packages, collaborate on scope identification, and generate documents from remote locations or job sites. Multiple team members can access the same project simultaneously, with updates reflected in real time across all active sessions.

4

Advanced Document Handling

The platform's AI reads, annotates, and extracts structured data from PDF construction documents including multi-hundred-page specification sets, drawing sheets, and addendum packages. Pelles' Compare feature performs automatic delta analysis when new addenda are issued, flagging scope changes at the specification clause and drawing detail level with citations back to the exact document location for each flagged change.

Pros & Cons

✓ Pros (4)

Time Efficiency Pelles reduces the time required to review a full MEP specification set from several hours of manual page-by-page reading to minutes of AI-extracted output review with direct citations — enabling preconstruction teams to process more bids per week with the same staff without extending working hours or reducing review thoroughness.

Error Reduction The DoubleCheck feature catches scope requirements buried in non-obvious specification locations — Division 01 general conditions, addendum amendments, and cross-referenced test standards — that human reviewers consistently miss when under deadline pressure, reducing the frequency of missed-scope change orders that erode project margin during construction.

Flexibility Cloud-based access from any browser without local installation allows estimators and project managers to review bid packages and access AI-extracted requirement summaries from any location, including remote project sites where local software installation is impractical or IT-managed device restrictions prevent non-standard application deployment.

Industry-Specific Customization Pelles' output templates and document intelligence models are calibrated specifically for MEP trade subcontractor workflows — RFI formats, submittal log structures, and specification clause extraction rules reflect how MEP contractors actually organize their preconstruction deliverables, unlike general-purpose document AI tools that require extensive configuration to produce trade-specific outputs.

✕ Cons (3)

Learning Curve New users require time to configure their organization's preferred output templates and to understand how Pelles' DoubleCheck and Compare features interact with different specification formats and drawing set organizations — particularly for teams accustomed to manual review workflows who need to change their preconstruction process to leverage the platform's AI outputs effectively.

Internet Dependency Pelles' cloud-based architecture requires a stable internet connection for all platform functions including document upload, AI processing, and output retrieval. Preconstruction work performed in areas with unreliable connectivity — remote construction sites, basement offices in older buildings — may experience upload delays or session interruptions that slow the review workflow.

Niche Focus Pelles' document intelligence models, extraction rules, and output templates are calibrated exclusively for MEP subcontractor preconstruction work. General contractors, civil subcontractors, or structural trades will not find applicable extraction logic or output formats, as the platform does not attempt to serve construction roles outside the mechanical, electrical, and plumbing specialty scope.

Who Uses Pelles?

MEP Subcontractors

Electrical, mechanical, and plumbing subcontractors use Pelles to process full bid packages faster, surface trade-specific requirements from complex multi-division specifications, and generate client-ready RFIs and submittal logs in their standard format — enabling them to pursue more right-fit opportunities without expanding preconstruction headcount.

Project Managers

MEP project managers use the Compare feature to monitor scope changes as addenda are released throughout the bid period, maintaining an accurate record of how each new document revision affects the project's labor and materials estimate before the final submission deadline.

Construction Analysts

Preconstruction analysts and estimating coordinators use Pelles' structured requirement extraction outputs to build more complete and accurate cost models, using the platform's DoubleCheck clause citations to verify that all specification-mandated testing, commissioning, and warranty requirements are included in the bid scope.

Tech-Savvy Construction Professionals

Forward-thinking MEP subcontractors adopting digital preconstruction workflows integrate Pelles into their existing project management and document control environments, treating the platform's AI outputs as a structured data source that feeds proposal templates, subcontractor bid forms, and project setup documentation.

Uncommon Use Cases

Academic construction management programs have used Pelles to give students hands-on experience with AI-assisted preconstruction document analysis as part of estimating and project management curriculum. Early-stage construction startups entering the MEP subcontracting market have used the platform to build estimating capacity without hiring experienced senior estimators during their initial bid development phase.
