Lead Research: 25 UK Construction Companies for 3D Tender Visualisation

I am looking for someone to research 25 high quality UK construction leads. Please do NOT provide a generic list of Preconstruction Directors. I already have hundreds of contacts. I need decision makers at contractors that are likely to require outsourced 3D construction sequencing, logistics planning, methodology visuals or tender visualisation. Company Requirements - UK main contractors only. - Annual turnover under approximately £500m. - Deliver technically challenging projects (city centre, refurbishment, infrastructure, healthcare, education, residential, etc.). - Companies that either: have hired for BIM, VDC, Digital Construction or 3D Visualisation roles, mention digital construction or BIM on their website, use construction animations or 3D visuals in bids or marketing, or show another clear indication that they value visual communication during preconstruction. Do NOT include: - Tier 1 contractors (Skanska, Balfour Beatty, Kier, Multiplex, etc.) - Architecture practices - ArchViz studios - Recruitment agencies Contact Requirements Find one relevant decision maker at each company, for example: - Preconstruction Director - Head of Preconstruction - Estimating Director - Bid Director - Digital Construction Manager - Head of Bid Management For each lead provide: - Company name - Company website - Approximate turnover - Decision maker name - Job title - LinkedIn profile - Business email (if publicly available) - Link to the evidence (job advert, company page, BIM/VDC page, project page, etc.) Important I am not looking for the biggest contractors. I am looking for companies that are genuinely likely to buy outsourced construction sequencing and tender visualisation services, where I have a realistic chance of reaching the decision maker. Please include only researched, qualified leads rather than a large generic list.
