Build an on-prem Python platform for 3D property evidence tours + measurement + UK business rates Check & Challenge packs (PDF + portal)

@AwaisChaudhry

Hello, I understand you need an on‑prem Python platform that turns large survey packages (including 3D Gaussian splats/scan outputs) into a VOA‑facing evidence portal and compliant Check/Challenge PDF packs for the UK business rates process. I will deliver a Docker Compose deployment with FastAPI, Celery, Postgres + PostGIS, and MinIO for storage; a krpano‑embedded tour with deep links; a Measurement Studio for room polygons, zones and exclusions with live totals; an evidence system for pins, screenshots and labels; a deterministic scheme engine with traceable calculators; PDF templates for Check and Challenge packs with plan sheets and evidence appendices; and immutable, versioned published packs. Deliverables include a working repo, runbook, API docs, QA path, and a DEMO-SHOP-001 dataset. I propose a phased plan: MVP Golden Path, Measurement Studio v1, Scheme Engine v1, Challenge Pack, Hardening, with regular commits and tests. What is the exact interface and format for the scheme calculators and trace data, and will you provide the schema and test cases? Do you have an existing PostGIS schema for rooms, zones, exclusions, and plan sheets, or should we design from scratch with your team? What performance targets do you expect for the resumable upload, pipeline processing, and PDF generation (throughput, concurrency, max package size)? Which 3D outputs and formats should we ingest and process beyond krpano compatibility, and are there any constraints on 3D Gaussian splats

Greetings, I understand you need an on-prem, audit-ready web platform that converts complex survey capture data into a secure evidence portal and immutable Check and Challenge PDF packs for the CCA process. The focus is a correct, deterministic backend with strong geometry handling, traceable calculations, deep-linked krpano tours, and versioned outputs that never mutate after publish. Our team has experience delivering on-prem, Docker-based systems using FastAPI, Postgres plus PostGIS, Celery workers, and S3-compatible storage. We can implement the full golden path, resumable uploads, processing pipeline, Measurement Studio with polygon zoning and exclusions, evidence pinning, deterministic scheme engine with computation trace, and PDF generation with deep links back to exact tour viewpoints. All packs will be versioned with immutable manifests, full audit logs, and scoped read-only sharing. A few questions to align early: 1. Do you already have a preferred resumable upload protocol, for example tus or multipart S3. 2. Should RBAC be role based only, or also per project. 3. Is krpano licensing already in place for deployment. The current bid amount is a placeholder to submit the proposal. Regards Yasir LEADconcept PS: Let me know, if you want to see our team past work to determine our skills/expertise or past customer's references.

I am comfortable embedding krpano with precise deep linking, building geometry editing tools with live area calculations, and producing professional PDF packs with verified links back to exact viewpoints. I work milestone driven, commit code regularly, document deployment thoroughly, and deliver systems that can be cleanly deployed and audited on a fresh environment. Best, Justin

@mayankinnovative

Hello, LACK OF INTEGRATED PROPERTY EVIDENCE, MEASUREMENT AND DOCUMENTATION Your project needs a secure on-premise Python platform that ties together 3D property tours, accurate measurements, and automated production of business rates Check & Challenge packs for UK properties. Without a unified system, workflows remain manual, time-consuming, and prone to errors when generating measurement data and supporting PDF documentation for challenges. DEVELOP ON-PREMISE PYTHON SYSTEM FOR TOURING, MEASURING AND PACK GENERATION I will build your **on-prem Python platform** with modules for interactive 3D property evidence tours, precise measurement extraction, and structured data storage. The solution will include backend services for managing 3D model uploads, spatial measurement computations, and logic to compile comprehensive Check & Challenge packs that combine property evidence, measurements, and required narrative. I will also integrate PDF rendering, secure user access, and a portal interface for reviewing and exporting reports. AUTOMATED PROPERTY DOCUMENTATION AND IMPROVED WORKFLOW You will receive a complete, secure on-premise platform that streamlines the creation of 3D evidence tours, accurate measurements, and ready-to-issue Check & Challenge packs. The result will reduce manual effort, improve data accuracy, and provide a reliable portal for producing high-quality PDF documentation used in UK business rates challenges. Thanks
