Design Software for Interior Designers
Manage Construction Drawings, Approvals, and Revisions Across Every Site with Onsite
Construction rework happens when site teams execute from outdated drawings. Onsite gives every team a centralized drawing repository with version control, digital approval workflows, and pin-based site queries so architects, consultants, project managers, and site engineers always work from the same latest approved drawing without searching email threads or WhatsApp groups.
Every site team always on the latest approved drawing version
Drawing approvals tracked digitally from submission to sign-off
Real-time coordination between design office and site teams on one platform

Built for Construction Companies Where Design Control Directly Determines Execution Cost
Construction rework costs between fifteen and thirty percent of project value in most cases. The primary cause is site teams executing from drawing versions that were superseded days or weeks earlier. Onsite gives every construction team type centralized drawing control, version visibility, and real-time approval tracking so design changes reach site teams before work begins, not after demolition is already required.
01
Interior and Fit-Out Firms
Interior and fit-out projects run on high-frequency design changes where a single revision to a ceiling layout, joinery specification, or finish selection requires every affected trade to update their execution scope immediately. Onsite gives interior teams a centralized drawing repository where revised drawings replace previous versions automatically, site engineers access only the current approved version, and client approval decisions are tracked with timestamps against each revision.
02
Developers and PMC Teams
Developers and PMC teams coordinate drawing submissions and approvals across multiple consultants simultaneously — architects, structural engineers, MEP consultants, and client representatives all reviewing and approving different drawing sets on overlapping timelines. Onsite centralizes every drawing submission, approval status, and revision record in one platform so PMC teams can see which drawings are approved, which are pending, and which have revisions outstanding without managing separate email threads per consultant.
03
Infra and EPC Companies
Large infrastructure and EPC projects generate hundreds of drawings across civil, structural, architectural, mechanical, and services disciplines, with revisions to one discipline frequently triggering dependency updates across others. Onsite lets EPC planning teams organize drawings by discipline and status, track which revisions have been issued to which site teams, and ensure no contractor executes from a drawing that has been superseded by a later approved revision in any discipline.
04
Industrial Projects
Industrial projects depend on precise layout drawings for equipment placement, service routing, and structural interfaces where a single dimension error or version mismatch during execution creates rework that costs significantly more to correct than the drawing error itself. Onsite gives industrial project teams strict drawing version control, role-based access ensuring each contractor sees only the drawings relevant to their scope, and timestamped approval records for every layout change.
Why Construction Companies Lose Lakhs to
Drawing Version Failures
In construction, design control means cost control. When drawing revisions scatter across email threads and WhatsApp groups, site teams inevitably execute from the wrong version. Approvals get lost. Revision histories disappear into conversation threads. The consequence is not a minor correction. It is rework that adds lakhs to project cost and weeks to delivery timelines.
Rework from Outdated Drawings
Site teams executing from superseded drawing versions is the single most expensive and most preventable construction cost. A wall built to an older layout, a finish applied before a client revision was issued, or an MEP route installed from a version since modified all require demolition before correct execution can begin.
Approvals Lost in Email Threads
Drawing approval cycles at most construction companies run through email chains involving architects, consultants, PMC teams, and client representatives simultaneously. When an approval arrives buried in a thread, there is no structured record of when it was given, who gave it, or which drawing version it applied to. Disputed approvals surface at handover when resolution is most expensive.
No Visibility into Version History
When a construction defect or execution error is identified on site, the first question is always which drawing the team was working from. Without a version history showing which drawing was issued to which team and when, reconstructing the sequence of events requires searching email archives and asking team members to recall details from weeks or months earlier.
Design Office and Site Working in Silos
Architects and consultants prepare revised drawings in the design office. Site engineers receive updates through informal channels that have no confirmation mechanism and no acknowledgment that the new version was actually downloaded and understood before execution continued. The two teams never operate from a shared view of which drawings are current, approved, and issued to site.
One Connected Drawing Management System from
Upload to Site Execution
Onsite connects drawing uploads, version control, digital approval workflows, and site team coordination in one platform. Every drawing is tagged by discipline and status, every revision replaces the previous version automatically, and every approval decision creates a timestamped record so architects, consultants, project managers, and site engineers always work from the same verified drawing without searching emails or WhatsApp.
Central Drawing Repository by Discipline
Every construction drawing uploaded to Onsite gets tagged by discipline, area, category, and version status immediately on upload. Architectural, structural, MEP, interior, and services drawings sit in one organized workspace accessible to every authorized team member simultaneously. Site engineers, subcontractors, and supervisors access the drawings relevant to their scope without searching shared drives, email attachments, or WhatsApp file histories that have no version awareness built in.
Version Control and Digital Approval Flow
When a revised drawing is uploaded to Onsite, the system automatically tags it as the latest version and locks all previous versions to prevent accidental use on site. Approval workflows route the new version to the designated approvers, architects, PMC teams, consultants, or client representatives along with status tracking showing pending, approved, rejected, or revision required at every stage without chasing through email threads for decisions.
Real-Time Coordination Across All Stakeholders
Once a drawing is approved in Onsite, every stakeholder with relevant access receives an instant notification confirming the approval, the drawing version, and the effective date. Site engineers know the moment a new drawing is ready for execution. Architects and consultants see when their submissions have been reviewed. Every upload, approval, rejection, and revision creates a timestamped record that builds a complete audit trail across the full project lifecycle.
Pin-Based Queries Directly on Drawings
execution tag the specific location on the drawing within the Onsite mobile app, add notes, attach site photographs as evidence, and raise a formal query that routes directly to the responsible architect or consultant. Clarification requests no longer travel through informal WhatsApp messages that get missed. Every query has a location reference, a timestamp, and a tracked resolution status.
Stop Managing Construction Drawing Revisions
Through Email and WhatsApp
When a revised drawing leaves the design office as an email attachment, there is no guarantee it reached the right people, no confirmation they downloaded it, no record of which version they were working from before the revision arrived, and no mechanism to prevent them from continuing to use the superseded version alongside the new one. WhatsApp is worse. Design management requires a system, not a messaging app.
Email drawing distribution has no lock mechanism preventing site teams from executing from a version that has since been revised.
WhatsApp drawing approvals leave no structured record of who approved which version, creating disputes that surface at project handover.
Multiple drawing versions accumulating in email threads give site teams no reliable way to identify which one is current approved.
Pin-based site queries cannot be raised on WhatsApp drawings because there is no drawing markup or location-tagging capability in a messaging app.
Construction Design Management Features Built for Drawing Control and Execution Accuracy
Onsite construction design management software connects centralized drawing storage, version-controlled approval workflows, and pin-based site coordination in one platform. Every drawing has a verified version history, every approval creates a timestamped record, and every site query routes directly to the responsible design team without traveling through informal WhatsApp messages that leave no audit trail.
Central Drawing Repository with Version Control
Every construction drawing uploaded to Onsite gets tagged by discipline, area, category, and version status at the point of upload. When a revised drawing replaces a previous version, Onsite automatically marks the new file as current and locks all earlier versions to prevent site teams from accessing superseded drawings by mistake. Subcontractors, supervisors, and site engineers see only the drawings relevant to their assigned scope based on role-based access controls. No searching email attachments for the correct file. No uncertainty about which version is currently approved for execution on any active site.

Role-based access ensuring each team sees only relevant drawings
Previous versions locked automatically when revised drawing is uploaded
Digital Approval Workflows with Full Audit Trail
Drawing approval cycles in Onsite route every submitted drawing to designated approvers with status tracking showing pending, approved, rejected, or revision required at every review stage. Every approval creates a timestamped record of who approved which version and when. Design offices see where each submission stands without chasing consultants for updates. Site teams know the moment a drawing is approved and begin execution on the verified current version. Complete approval history sits in one place for dispute resolution and project handover documentation without searching email archives from months earlier.
Pin-Based Site Queries and Real-Time Coordination
Site engineers who identify discrepancies or need clarification during execution open the relevant drawing in the Onsite mobile app, pin the exact location on the drawing where the issue exists, add notes describing the problem, attach photographs as evidence, and raise a formal query that routes instantly to the responsible architect or consultant. The query carries a location reference, a timestamp, and the drawing version it applies to. Architects and consultants respond within the platform, creating a complete record of every design clarification that was raised, answered, and resolved during the project without a single informal WhatsApp message.

What Construction Companies Say About Onsite Construction Design Management Software
Construction companies using Onsite design management report fewer rework incidents, faster drawing approval cycles, and complete version visibility across every active site without searching email threads or WhatsApp histories.
Managing drawing revisions across multiple concurrent projects was creating coordination failures between our design office and site teams. Site engineers were executing from versions that had been superseded. With Onsite, every team accesses the current approved drawing from the same platform. Revision disputes that previously surfaced at handover now surface in the approval workflow before any work begins.

Extended Features for Construction Design Management
Onsite construction design management goes beyond drawing storage and approval tracking. Role-based access control, timestamped audit trails, mobile drawing access from site, multi-discipline organization, and real-time approval notifications connect every design management workflow to the execution teams acting on those drawings without manual coordination effort.
Role-Based Drawing Access Control
Every team member at Onsite sees only the drawings relevant to their assigned scope. Subcontractors access their trade-specific drawings. Site engineers access their discipline. Architects and consultants access the full repository. Sensitive design documents stay protected from unauthorized access without requiring manual distribution of individual files to individual recipients for every revision cycle.
Timestamped Audit Trail
Every upload, approval, rejection, revision, markup, and download in Onsite creates a timestamped record showing which user performed the action, which drawing version was involved, and when it happened. This audit trail supports dispute resolution at handover, accountability reviews during execution, and compliance documentation for projects requiring formal design change records.
Multi-Discipline Drawing Organization
Architectural, structural, MEP, interior, and services drawings for the same project sit in one organized workspace tagged by discipline, area, and category. Project managers and PMC teams see the full drawing set organized by type rather than searching across separate folders, email attachments, or shared drives for drawings from different consultants.
Real-Time Approval Notifications
When a drawing moves from pending to approved, rejected, or revision required in Onsite, every stakeholder with relevant access receives an instant notification confirming the status change, the drawing version affected, and the action required from their side. Approval cycle delays caused by consultants not knowing a submission was waiting for their review are eliminated.
Mobile Drawing Access from Sites
Site engineers access the current approved version of any drawing from the Onsite mobile app at the construction site without returning to the office or calling a colleague to send the file. Drawing access, version confirmation, and query submission all happen from the same mobile app used for daily progress tracking and attendance.
Drawing History and Change Log
Every drawing in Onsite maintains a complete revision history showing every version uploaded, every change made, every approval given, and every rejection issued from the first submission to the current approved version. Teams working on long-duration projects can trace the full design evolution of any drawing without reconstructing the history from email archives.

Stop Construction Rework from Outdated Drawings. Start Managing Designs with Onsite.
Drawing revisions that travel through email and WhatsApp reach some teams immediately and others days later, with no confirmation either way. Onsite replaces scattered drawing distribution with a centralized platform where every team accesses the current approved version in real time, every approval creates a timestamped record, and every site query routes directly to the responsible design team without a single informal message.
FAQs
Construction design management software is a platform that helps construction teams store, organize, version-control, and approve drawings during project execution. Unlike general file storage tools, construction-specific design management connects drawing versions to approval workflows, gives site teams role-based access to only the drawings relevant to their scope, and allows site engineers to raise pin-based queries directly on drawings from mobile devices. Onsite ensures every team from the design office to the active construction site always works from the same current approved drawing without searching email attachments or WhatsApp histories.
Onsite prevents outdated drawing rework through automatic version control at the point of upload. When a revised drawing replaces a previous version, Onsite locks all earlier versions immediately so site teams cannot access superseded drawings by mistake. Role-based access ensures each team member sees only their current approved scope drawings rather than a full archive where older versions remain accessible alongside newer ones. The combination of automatic version locking and controlled access eliminates the distribution gap between design office approval and site team awareness that causes most drawing-related rework.
Every drawing uploaded to Onsite receives a version tag based on its upload sequence and the status assigned by the uploading team member. When a revision is uploaded to replace a previous version, Onsite automatically marks the new file as current and moves all earlier versions to a locked archive that remains accessible for audit and historical reference but is no longer presented to site users as an active drawing. Site engineers and subcontractors always see the current approved version without needing to check which file is most recent across multiple uploads.
When a drawing is uploaded to Onsite, the submitting team assigns the relevant approvers from the platform — architects, PMC representatives, structural consultants, MEP engineers, or client representatives depending on the drawing type. Each approver receives a notification, reviews the drawing within Onsite, and marks it as approved, rejected, or requiring revision. Every decision creates a timestamped record showing who acted on which version and when. Design teams see the exact approval stage of every submission without sending follow-up emails to consultants for status updates.
Pin-based queries allow site engineers to raise clarification requests directly on the drawing rather than describing a location issue through a WhatsApp message or phone call. The site engineer opens the relevant drawing in the Onsite mobile app, taps the exact location where the issue exists, adds a written description of the clarification needed, attaches site photographs as evidence if required, and submits the query. The query routes instantly to the responsible architect or consultant who responds within the platform, creating a complete location-referenced resolution record for every design clarification raised during the project.
Yes. Onsite organizes drawings by discipline, area, and category within a centralized repository so architectural, structural, MEP, interior, and services drawings for the same project sit in one organized workspace. Project managers and PMC teams see the full drawing set organized by type. Subcontractors and site engineers see only the drawings relevant to their assigned scope based on role-based access. For EPC and infrastructure projects managing multi-discipline drawing sets with revision dependencies between disciplines, this centralized organization prevents version conflicts between drawing types that frequently cause coordination failures during execution.
Onsite replaces informal drawing distribution through email and WhatsApp with a centralized platform where design offices upload approved drawings and site teams access them in real time through the mobile app. When a drawing is approved, relevant site teams receive an instant notification confirming which drawing is current and ready for execution. Site engineers raise queries directly on drawings through the mobile app rather than calling the design office or sending WhatsApp messages that may not reach the right person. Both teams work from the same verified drawing data simultaneously without communication gaps between design approval and site execution.
Yes. Interior and fit-out projects involve some of the highest drawing revision frequencies in construction, with client design changes, material substitutions, and scope adjustments creating new drawing versions throughout the project lifecycle. Onsite is specifically effective for interior companies because version control prevents site teams from executing to a design the client changed two days ago, approval workflows keep client sign-offs documented with timestamps rather than buried in WhatsApp conversations, and pin-based queries allow site teams to raise finish and layout clarifications directly on drawings from the active site without delaying execution for informal responses.
