I can build your end‑to‑end AI tendering agent that reads drawings, photos and documents, performs accurate material/labour take‑offs, prices items using your supplier data, and outputs a fully costed tender package. I’ve delivered CV + document‑understanding systems combining drawing parsing, IFC/DWG/PDF extraction, OCR/layout analysis, and semantic quantity detection. My approach uses a unified pipeline: ingest CAD/BIM files, vector PDFs, site photos and spreadsheets; extract geometry, annotations and quantities; classify materials; and map outputs into your BOQ and supplier‑price structures. Backend in Python/FastAPI with containerised model serving, secure storage, audit trails and estimator override UI. I’ve worked with ezdxf, IfcOpenShell, Forge‑style workflows, photogrammetry, and ETL pipelines for mixed drawing/photo datasets. I can integrate supplier APIs, your labour rates and Excel templates to generate tender documents ready for submission. I’ll define model metrics, validation sets, retraining cycles and a clear milestone plan to reach production reliability.

Hi, I’m Jitendra. I understand you need an AI/ML system for construction tendering that can read CAD/PDF/BIM drawings, extract quantities (take-offs), process site images, and generate fully costed BOQs using your supplier and labour rates. I can design this as an end-to-end AI pipeline with document understanding + computer vision + structured cost-engine logic. Approach: Document AI layer: OCR + layout parsing for PDFs, scans, spreadsheets CAD/BIM processing: DWG/DXF/IFC parsing using specialized libraries (e.g., IfcOpenShell, ODA tools) Vision models: object detection/segmentation for materials and site images Quantity take-off engine: geometry + rule-based extraction + validation layer Costing engine: integration with supplier price DB + labour rates Output: automated BOQ + tender documents (Excel/PDF export) Optional UI: review dashboard for human validation and overrides Tech stack: Python (FastAPI), PyTorch, OpenCV, HuggingFace models, PostgreSQL, Docker, cloud deployment (AWS/GCP), vector search for document intelligence. Key focus: Accuracy, traceability (linking every quantity back to source drawings), and a human-in-the-loop validation system for reliability. I have 10+ years of experience in AI systems, computer vision, and data extraction pipelines, including document-heavy automation workflows. I can start with a phased MVP (document parsing + BOQ generation) and gradually extend into full CAD/BIM + photogrammetry support. Thansk JItenra

Hi, We will build your AI tendering agent to parse CAD drawings (DWG, DXF, IFC), site photos, and documents, then automate take-offs, quantity extraction, and costed BOQ generation using your actual supplier prices and labour rates. For the CV pipeline, we will use layout analysis and segmentation models to detect rooms, walls, and elements from vector PDFs and raster drawings. Each detected element maps to your price list via a matching layer, so the final tender document traces every cost line back to its source drawing or photo. A couple of quick things to confirm: 1) What formats do you currently receive most often (DWG, vector PDF, Revit)? 2) Do you have existing BOQ templates and supplier price lists in XLSX or CSV we will ingest from day one? The number quoted here is a starting estimate. Ready to start whenever you are. Faizan

Hello! An AI tendering agent for a residential building company in Hackney — reading drawings and site photos, performing material and labour take-offs, costing against actual supplier prices and outputting complete tender documents. Genuinely ambitious AI engineering scope and I've read the full spec carefully. Python/FastAPI backend, Claude or GPT-4o Vision for drawing and photo analysis, ezdxf for DWG/DXF parsing, IfcOpenShell for IFC/BIM files, OCR pipeline for PDF drawings and scanned documents. Supplier price list ingestion via REST API or spreadsheet upload, labour rate configuration, automated BoQ generation with quantities traced back to source drawings. Simple review UI for your estimators to check, override and approve before final tender document generation. AWS for secure hosting with encrypted storage for client drawings and site photos. The hardest part is geometry extraction from CAD drawings — I'd propose a phased approach starting with vector PDF and DXF parsing before tackling RVT/BIM formats. Send me a message and let's scope Phase 1 properly. Mateo

Hi, I reviewed your AI tendering and estimating platform requirements and believe this can be developed as a scalable AI-assisted construction estimating system. I have experience with construction workflows, drawing analysis, BIM/CAD data processing, backend development, document automation, and AI-powered data extraction. The solution can ingest drawings, BIM models, PDFs, photos, supplier price lists, and labor rates, then generate take-offs, BOQs, cost estimates, and tender documents with full traceability back to source files. I can design the platform using Python, AI/CV pipelines, FastAPI services, cloud infrastructure, and an estimator review interface to validate quantities and costs before submission. The architecture can also support future integrations with supplier portals, accounting systems, and ERP platforms.

Building an AI agent for tendering sounds like an exciting challenge. I see you're looking to streamline the cost estimation and take-off process, which is key in construction projects. With around 10 years of experience in AI development and data analysis, I can help create an intelligent solution tailored to your requirements. Your focus on combining graphic design tools like AutoCAD with AI is intriguing and essential for generating accurate estimates. I'm confident we can develop a user-friendly interface that enhances decision-making and efficiency. Some similar things I've built: a regional booking platform for a tutoring company, an internal CRM for a property agency, and a React Native field-reporting app. Let’s connect and discuss how we can make your vision a reality. Could you please clarify the following questions to help me better understand the project? Q1: What specific features do you envision for the AI agent in terms of user interaction? Q2: Are there particular data sources or existing systems the AI agent needs to integrate with? Q3: What are your expectations regarding the design and user experience of the interface?

Hi there, Building an AI Tendering Agent that parses vector PDFs, native RVT/DWG files, and site photos requires a deep understanding of construction estimation, NRM rules, and BIM metadata structures. As an Architect, BIM Manager, and Python developer, I bridge the gap between advanced data engineering and real-world quantity surveying. I specialize in automating architectural workflows and metadata extraction. I am ready to develop an end-to-end AI pipeline using Python (FastAPI), leveraging libraries like ezdxf, IfcOpenShell, and computer vision models to execute automated material and labor take-offs. My Approach for your AI Agent: Ingestion Pipeline: Secure ETL pipelines to parse geometry and text from PDFs, CAD/BIM, and images. Vision & Layout Parsing: OCR and layout analysis to map quantities into structured BoQs connected to your supplier data. Traceability UI: A clean review interface for estimators to verify and audit quantities back to the source document. GDPR-compliant and ready for a Docker deployment. Let's discuss it.
