How an El Dorado Hills Engineering Firm Made Its Workstations Keep Up — and Cut Downtime by 83%
For most office workers, a file that takes a few seconds to open is nothing. For a civil engineer working in Civil 3D, those seconds are a design decision deferred and a billable hour quietly bleeding away. When the workstation can’t keep pace with the drawing, the bottleneck isn’t really the software — it’s the whole project.
A 29-person El Dorado Hills civil engineering firm had hit exactly that wall. The work was growing faster than the technology underneath it, and engineers were spending more of their day waiting than designing. Here’s how RJ PRO Tech Group’s Managed IT Services rebuilt the environment around performance and protection — and cut critical downtime by 83%.
Firm Profile
| Industry | Civil Engineering |
| Location | El Dorado Hills, California |
| Team size | ~29 employees |

| Headline result | 83% fewer critical IT incidents in six months |
When the tools couldn’t keep up with the work
The firm wasn’t fighting one dramatic outage — it was fighting friction that showed up all day, every day. Heavy drawings crawled on underpowered workstations, and a storage array that had been fine two years earlier simply couldn’t keep pace with current project demands. Engineers waited for files to open and waited again to save them. Off-site, remote access dragged just when field and client work needed it most.
Underneath the performance complaints sat a quieter concern. Valuable project data was protected by thin security, and the backups — the firm’s last line of defense — had never actually been tested for recovery. Leadership had reached the point most growing firms reach: they wanted a partner who would get ahead of problems, not just show up after something broke.
Starting with the full picture
RJ PRO Tech Group’s first step wasn’t to swap hardware — it was to understand the whole environment. A comprehensive assessment examined workstation and storage performance, firewall configuration, endpoint security, Microsoft 365 settings, backup systems, patch management, and disaster recovery readiness.
The review surfaced a pattern typical of a fast-growing engineering firm: performance and reliability gaps that hadn’t yet caused a crisis, sitting right next to security weaknesses worth closing before they could. Everything was prioritized by business impact, so the work that would free up engineers’ time came first.
The work that changed things
Improvements were rolled out in phases so nothing interrupted active project work — and they targeted exactly where an engineering firm feels it: performance first, then security and resilience.
Performance, addressed at the source. Every workstation, server, and critical network device was placed under continuous monitoring with performance trending, so developing issues get caught before they become outages. The storage and network bottlenecks that had been slowing large-file work were resolved first, restoring day-to-day speed for the whole team.
Modern, layered cybersecurity. Project data was wrapped in endpoint detection and response (EDR), Multi-Factor Authentication, email threat filtering, DNS security, and automated patch management — protection built around the value of engineering files, not bolted on as an afterthought.
Microsoft 365, tuned for large-file collaboration. The environment was optimized specifically for the way an engineering team actually works: moving big drawings and models across the group without the usual friction.
Backups you can trust. The firm moved to monitored, verified backups with cloud replication and quarterly disaster recovery testing. Leadership no longer assumes the backups work — they can confirm it.
Support that responds in minutes. A fast Help Desk lane was opened for workstation and file-access issues, with most problems resolved remotely within minutes instead of lingering for a day.
Six months of measurable change
| Metric | Before | After |
|---|---|---|
| Critical IT incidents | Frequent | Reduced by 83% |
| Weekly downtime per engineer | 4+ hours | Under 40 minutes |
| Large-file load times | Slow | Markedly improved |
| Windows patch compliance | 62% | Over 98% |
| Backup confidence | Assumed | Fully verifiable |
What leadership actually felt
Beyond the metrics, the firm noticed the difference where it counts. Engineers recovered real design hours simply by no longer waiting on files and workstations. Dependable remote access made flexible, off-site work practical across project teams. And executives gained something they’d been missing: confidence that project data was protected and recoverable — without the surprise repair bills the firm used to absorb every quarter.
Why engineering firms can’t afford reactive IT
Engineering firms run on their technology. CAD workstations, large project files, and remote collaboration aren’t support functions — they are the work. When performance slips or data is exposed, it’s the billable output and the client trust that take the hit.
That’s the case for RJ PRO Tech Group’s managed IT services: fast, reliable workstation performance; dependable remote access to large project files; layered cybersecurity for valuable project data; predictable IT budgeting; a real business continuity plan; and support that responds before small issues interrupt a deadline.
Why the firm chose RJ PRO Tech Group
The decision came down to wanting a proactive local partner rather than a reactive fix-it service. The firm valued RJ PRO’s Northern California expertise, its security-first approach, responsive support, transparent monthly pricing, proactive monitoring, and strategic technology planning aligned with where the business is headed.
