SiteScribe: An Evidence-Centric, Multi-Tenant Change Order Intelligence Platform for Construction Projects

Site logs, request for information (RFI) documents, plan revisions, contracts, and photographs taken in the
field constitute large volumes of heterogeneous evidence associated with the construction of buildings, roads, and
highways, among other projects. In the construction industry, construction evidence artifacts can be located across
multiple, disconnected channels, which makes capturing, retracing, and auditing Change Orders (COs) time consuming
and difficult. In this paper we describe SiteScribe, a collaborative, evidence-focused, multi-tenant platform with the
ability to consolidate evidence collection, signal identification, event triaging, and CO construction automation into a
single process. SiteScribe uniquely features role-based and project-specific access control, evidence identification,
segregation, and optional AI-based semantic enhancement for evidence identified and packaged for export, with secured
evidence export by means of PDF/ZIP combined with a SHA-256 manifest for evidence-based COs. SiteScribe promotes
stakeholder communication and project governance by means of comments, notifications, webhooks, approvals, and
evidence COs sustained within a project’s historical record. SiteScribe’s architecture employs a modular design for each
functional area (interface, domain logic, persistence, and external systems) to facilitate secure, scalable, and maintainable
operation across local and cloud-sourced systems. The proposed solution addresses the primary industry challenge of
converting fragmented field evidence into defensible contractual outputs, thereby enhancing transparency and minimizing
operational friction. This work contextualizes SiteScribe as a construction digital evidence change management solution,
as well as a basis for further studies on decision latency, quality of traceable evidence, and workflow reliability.
