How Long Does It Take to Switch IT Providers Without Disrupting Active Construction Projects?

A construction company can typically switch IT providers in 2 to 4 weeks without disrupting active projects, done in four phases: discovery and documentation, a parallel-run period, a scheduled one-day cutover, and a short stabilization window. The risk isn't the switch itself, it's switching without a documented plan for jobsite connectivity and construction software during the transition.

Switching IT providers takes most construction companies 2 to 4 weeks from decision to full cutover, and it doesn’t have to touch active jobsites or projects if it’s run in the right order. The four phases: discovery and documentation (about a week), a parallel-run period where the new provider is set up alongside the old one, a scheduled one-day cutover, and a short stabilization window afterward. See our managed IT services page for what you’re switching to, or what a managed IT package should include to know what to expect from the new provider.

Phase 1: Discovery and documentation (roughly 1 week)

The incoming provider inventories everything: devices, servers, network equipment, Microsoft 365 setup, and any construction software like Jonas, AutoCAD, or SOLIDWORKS, including how each jobsite connects back to the office. This phase runs entirely in the background. Nobody’s daily work changes, and active projects continue exactly as they were.

Phase 2: Parallel setup, old provider stays live (roughly 1 to 2 weeks)

The new provider builds out monitoring, security tooling, and documentation for your environment while your outgoing provider’s systems remain fully in place and untouched. This is the phase that protects you: if anything about the new setup isn’t ready, nothing has been cut over yet, so there’s no risk to email, files, or jobsite connectivity in the meantime.

Phase 3: The cutover (typically one day)

This is the only phase where anything actually changes for your team, and it’s scheduled for a low-activity day, specifically to avoid disrupting an active bid deadline or jobsite milestone. Staff should be back on fully working systems the next morning. Jobsite connections and construction software licensing get validated as part of this phase, not left as an afterthought.

Phase 4: Stabilization (roughly the first 1 to 2 weeks after cutover)

The new provider watches closely for anything that slipped through discovery, an overlooked printer, a VPN profile, a jobsite firewall rule, and fixes it fast rather than waiting for a support ticket. This is also when documentation gets finalized so ongoing support runs smoothly going forward.

What actually causes disruption during a bad switch

It’s almost never the office network. The risk is jobsite connectivity and construction software getting overlooked because they’re less visible than office email and file access. A trailer that loses its VPN connection, or a Jonas license that wasn’t accounted for, are the kinds of gaps that turn into real project delays. A documented discovery phase that explicitly lists every jobsite and every line-of-business system is what prevents that.

Timing it around your active projects

The cutover day is the only part of this process that needs a quieter window, avoid a week with a bid deadline or a critical inspection. Discovery and parallel setup can run entirely alongside normal project activity without any disruption, so the calendar constraint is smaller than most companies expect.

Considering a switch but worried about timing it around an active project? Tell us your current setup and jobsite count, and we’ll map out a realistic timeline before you commit to anything.

Considering a switch mid-project?

Tell us your current provider situation, active jobsite count, and software (Jonas, AutoCAD, SOLIDWORKS), and we'll map out a realistic switch timeline before you commit to anything.

FAQs

Will we lose access to email or files during the switch?

You shouldn't. A properly run switch keeps your old provider's systems live and untouched until the new provider has fully validated everything works, so there's no gap where email or files are unavailable.

Can we switch providers in the middle of an active bid or project deadline?

It's better to avoid scheduling the cutover itself during a critical deadline week, but the discovery and preparation phases can run in parallel with active projects without any disruption. Only the final cutover day needs a quieter window.

Does our old provider need to cooperate for a smooth switch?

It helps, but it's not required. A competent incoming provider can document your environment independently, credentials permitting, and doesn't need active cooperation from an outgoing provider who may not be motivated to help.

What's the biggest risk during a provider switch for a construction company?

Jobsite connectivity and construction software (Jonas, AutoCAD, SOLIDWORKS) getting overlooked because they're less visible than office email and files. A real transition plan documents every jobsite and every line-of-business system explicitly, not just the office network.

How long does the actual cutover take?

Typically a single day for a 10 to 50 employee company, with staff back on new systems the next morning. Larger environments with more servers or jobsites may need a second day for anything that doesn't fully validate the first time.
