Custom Construction Software and AI

Less time chasing information. More time moving jobs forward.

We build custom software and AI around how general contractors and subcontractors work. Connect your existing tools, reduce repetitive tasks, and build the capabilities your team needs to keep work moving between the field and office.

Clear scope. Fixed price. You own what we build.

Your workflows

Custom construction software built around your workflows.

From project and financial reporting to change approvals, field-to-office handoffs, and preconstruction document review, we develop software around the work your team needs to get done.

We review your existing tools, where information gets stuck, and who needs to review or approve it. Then we agree on a focused improvement and how you’ll measure whether it helps.

Explore general contractor workflowsExplore subcontractor workflows
  • Project and financial reporting

    Pull job costs, hours and change orders from Procore, Sage or spreadsheets into the WIP and owner reports you already use.

  • Changes and approvals

    See every change order and RFI in one place: what’s pending, what’s overdue and who owes the next step.

  • Field-to-office handoffs

    Daily logs, time and photos from the field reach the office once, without retyping them into three systems.

  • Preconstruction document review

    Turn subcontractor proposals into a side-by-side bid comparison, with scope gaps flagged for your estimator.

These are examples of workflows we can explore together. The right solution depends on your systems, data, and requirements.

The problem
Business information lived in separate systems, so keeping it up to date took manual work.
The solution
An AI-powered platform connecting their systems into one source they own.

The result

How we work

Start with a conversation. Build around what matters.

You don’t need a technical plan before talking with us. Start with the part of the week that takes more coordination than it should.

  1. Step 1

    Understand your workflow

    We talk with the people involved and review the tools, handoffs, and requirements behind the problem.

  2. Step 2

    Agree on scope and success

    We identify a manageable improvement and explain the proposed work, costs, responsibilities, and how you’ll assess whether it helps.

  3. Step 3

    Build and review together

    We build or configure the agreed solution, test it with the people who will use it, and gather feedback before a wider rollout.

  4. Step 4

    Train, hand off, and support

    We agree on training, handoff, and support. Then we pick the next improvement together, based on what you’ve learned.

We agree on how you’ll receive updates, review progress, and raise questions.

The starting point should fit the need.

We’ll recommend a starting point based on your priorities, existing tools, and team.

Practical AI

AI that supports your team’s judgment.

AI can help organize information, prepare drafts, and flag items for attention. Its role should be clear, and its output needs to be checked where accuracy and judgment matter.

Before introducing AI into a workflow, we work through the information it needs, who can access it, and which actions require approval.

In practiceIllustrative example

AI extracts information from subcontractor proposals into a comparison for review. Your estimator checks the source documents, resolves scope questions, and makes the final assessment.

  • Keep your people involved

    Your team reviews outputs that affect estimates, commitments, payments, or project decisions.

  • Define access

    We agree on the relevant data sources and permissions, along with how the proposed tools handle your information.

  • Test against real work

    We check the proposed workflow using representative examples and discuss its limitations before expanding its use.

Costs & ownership

Understand the investment and stay in control.

For custom software projects, we agree on the scope, deliverables, and fixed price before development begins. Additional work is quoted for approval.

We also explain expected hosting, AI usage, and other provider costs. You own the custom code we develop for you and can choose who supports it.

Scope and pricing are confirmed after we discuss your requirements.

  • Start with what you already have

    We assess whether existing features or integrations can address the need before recommending custom work.

  • Check the connections

    We review your software versions, available access, and data requirements before confirming what can connect.

  • Plan for ongoing use

    We explain maintenance needs, third-party dependencies, and the support included in your engagement.

FAQs

Questions before we get started

  • We start by checking whether your existing software can handle the need through its current features, configuration, or available integrations. If a gap remains, we can develop a focused application or connection around that workflow. We explain the proposed scope, costs, and maintenance needs before you decide whether custom development makes sense.

  • No. Bring a process that is taking too much time, information that is difficult to find, or a problem your team keeps working around. We’ll help you explore possible next steps.

  • Yes. A focused project can address one defined need and give your team experience with the approach before considering more work.

  • We agree on who needs to participate and when, including workflow discussions, access to relevant systems, testing, and training. The commitment depends on the project.

  • Our goal is to help your team work more efficiently. We focus on reducing repetitive tasks, making information easier to find, and cutting down on manual entry so your people have more time for coordinating jobs, solving problems, and building relationships. Your team’s experience and judgment remain central to how the work gets done.

  • Before connecting systems or introducing AI, we review the information involved, access requirements, and your company’s policies. We explain the proposed providers and data handling so you can assess the approach.

  • We agree on handoff, training, and support before work begins. You can arrange ongoing help with Build Lean or choose another team to maintain the custom software you own.
