Most construction software is expensive because of marketing, not features. If a subscription costs $5,000 a year and customers stay four or five years, the vendor can spend thousands winning each one. Free tools don't have that budget, so you rarely hear about them. When my Bluebeam renewal came up, I spent five minutes looking for an alternative and found a free, open-source PDF editor that does markups, measuring and PDF comparisons. For the simple markups and counts I do, it's been just as good. Free software comes in two kinds: - Open-source projects. The code is public, so anyone can see how the software works, use it for free and help improve it. They're usually built by a community of developers or a company that makes money elsewhere, rather than through subscriptions. Before you rely on one, check its GitHub page (where the code lives). Recent updates and plenty of stars mean someone is still looking after it. - Free tiers from paid vendors, like Trello, Google Drive or Jibble. They're useful, but they exist to get you locked in before you upgrade. Others worth a look: Blender with the Bonsai add-on for 3D models and IFC files, GanttProject instead of Microsoft Project, LibreOffice instead of Office, Manager for desktop accounting, and Operum, the estimating and contract management app I built and made free. For cheap tools I wouldn't bother. I pay about $20 a month for QuickBooks and would rather have the best system there. If you can't find what you need, describe the features and budget to ChatGPT or Claude and ask for a free option. What are you paying for that you'd happily swap out?

Grok Bot now handles most of my day-to-day admin. I still use Claude for structured work like a detailed estimate, where I want tested skills and control over the output. For the small random jobs, Grok Bot is simpler because it writes its own skills, keeps its own memory and sets up its own scheduled tasks. All you manage is the bots. Two rules get the most out of it. First, if you're not sure it can do something, ask it. When it told me it couldn't connect to SharePoint, I asked for a workaround and it found one. Second, give every bot one clear goal. A bot doing ten different jobs gets its memory muddled. Start by telling it about your business and connecting your software. Use an MCP or API connection where one exists, and a browser login as the slower fallback. Give anything sensitive read-only or draft-only access. - Business development: finds tenders and gives a go/no-go recommendation - Pre-construction: tracks bids and follows up submissions - Commercial manager: protects margin and contract position - Finance: cash flow and getting paid - Systems and compliance: insurances, SWMS and paperwork - Project assistant: one per project, coordinating delivery A general manager bot can sit on top and hand work to the others. Which job would you hand to a bot first? Full walkthrough: https://youtu.be/0hzqCMowrys

Most construction businesses run on Microsoft, so Copilot is often the AI you already have. It's more confusing than ChatGPT or Claude, but it makes sense once you treat it as three separate tools. Chat is for questions and answers. Turn on Work IQ so it can read your SharePoint files, email and Teams, and set up one notebook per project so each chat has the right context. Agents are reusable instruction packs: you open the agent, then tag the project notebook into the chat. That's the reverse of how projects work in Claude or ChatGPT. Co-work is where Copilot edits files and runs tasks inside a SharePoint project. You can schedule jobs like a daily project update in Teams, load skills and connect other apps. Custom connections usually need your IT admin's approval. Copilot Studio is for building company tools, like more advanced agents, fixed workflows similar to Zapier, and simple apps. Agents you build there show up in Chat, but I still can't get them to appear in Co-work. If your company is on Microsoft 365, which of these three do you actually use?

I've moved from Claude Cowork back to Claude Code for nearly all my work. You open it on a folder on your desktop, type your prompts and it does the work. Cowork now runs in the cloud on copies of your files, so you can't move or delete the originals which is super frustrating. These are the things I've been using: - Side chats (/btw) for quick questions without cluttering the main chat. - /goal for long jobs, like checking every contract clause against your standard terms or categorizing 100 invoices. - Sidebar sections, so each project keeps its chats together. - The session rail, which shows how much context you've used. I set auto-compact at 400,000 tokens because results get worse as the window fills. I also built a take-off checker with Mods that flags anything Claude was unsure about, but I'm still working out where Mods are most useful. The idea seems cool, just unsure how useful it actually is Full walkthrough: https://youtu.be/fs4PGGZmp_0

The recent models, Opus 5.5 and GPT-6 Astra, have been genuinely quite amazing. I’ve built complete 3D models from a prompt + drawing and turned them into 5D project plan. They've changed how we should build skills. A skill should no longer explain how to do the task. If you over-specify the process, you're more likely to get a worse result. Instead, specify the outcome, the source information and the guardrails around the task. This week I'm giving you eight practical strategies to build better Claude skills. As always, it's structured around News, Inform and Work. News GPT-6.1 Terra. OpenAI's new mid-tier model (26 October) is built for visual reasoning, computer use and clearer writing, at half the cost of GPT-5.6 Terra. It's in ChatGPT Work, Codex and the API. Read OpenAI's announcement. Claude 2.0. This is the name people are giving the rebuilt Claude desktop app. It's not a collection of new features. The features I'd try first, mostly in the Code tab: - Nested sessions: one chat splits a big job into helpers. For a bid review, that's scope, contract, programme and risk, combined into a go/no-go summary. - /goal: gives Claude a finish line, such as every requirement priced, excluded or raised as a clarification. - Docs, Slides and Design: editable documents, decks and one-pagers inside Claude, now on every plan. - Dashboards: live dashboards you share as a link (paid-plan beta). Features are rolling out in stages, so check your plan if you can't see one. Inform: about 1 in 6 US construction businesses now use AI 16.1% of US construction employers told the Census Bureau they had used AI in the two weeks to 4 October 2026, up from 7.4% in November 2025. See the Census data. My takeaway: I am consistently reminded that if you’re building skills, creating 3D models, etc. you are still part of a complete bubble. Of that 16.1% most people would be prompting it to ask questions, not really building anything meaningful.
