SELECTED EXPERIENCE

Work measured by what had to keep running.

VALD experience spans utility-scale modernization, distributed national operations, municipal brownfield migration, process-plant recovery, and the engineering records that make the next change defensible.

These highlights describe delivered engineering work and active programs. Named details are used only where the work is already public; protected engagements are deliberately generalized without sanding off the technical substance.

01MULTI-UTILITY / ALASKA

Statewide utility modernization across four military installations

Unified power generation and distribution, potable water, wastewater, steam, natural gas, historian, and operations visibility across geographically separated facilities.

  • Three competing control platforms tested before selection
  • 430,000-point historian architecture
  • Multi-year phased modernization with operating utilities kept online
PUBLICLY DOCUMENTED
02ALTERNATIVE FUELS / NATIONAL

Remote operations architecture for hundreds of fueling facilities

Mixed-vendor PLC connectivity, cellular and hardline telemetry, segmented customer access, centralized alarming, historian aggregation, and national operations-center visualization.

  • 300+ CNG and 50+ LNG facilities in the operating network
  • Thirteen operational applications unified at the NOC
  • Ten-display ThinManager architecture documented in a published customer story
PUBLICLY DOCUMENTED
03MUNICIPAL WATER / BROWNFIELDS

Legacy DCS reconstruction for a major wastewater migration

Native ABB engineering evidence reconstructed into browsable HMI, logic, I/O, drawings, migration mappings, verification packages, and fresh-capture rebuilds.

  • 407 legacy mimic screens reconstructed
  • 42,998 function blocks made browsable
  • 43,456-point census supporting scope and migration planning
CLIENT-SAFE SUMMARY
04RENEWABLE GAS / RECOVERY

Controls triage that returned an underperforming gas plant to design intent

Recovered owner access, rebuilt historian visibility, corrected PSA/TSA timing, restored the H2S system, redesigned secure remote support, and closed operating defects in phases.

  • Plant access restored to the owner
  • H2S process returned to service
  • Facility recovered to intended flow rates
CLIENT-SAFE SUMMARY
05BIOMETHANE / THIN CLIENTS

Resilient plant visualization built around a segmented wireless architecture

A redundant virtualized control-room design joined Wonderware InTouch, ThinManager, industrial thin clients, mobile visualization, IP cameras, and secure remote support without exposing the control servers.

  • Five-display redundant control-room architecture
  • Secure visibility extended to 150 satellite sites
  • Documented by ThinManager in its Integrator Spotlight
PUBLICLY DOCUMENTED
WHO IS BEHIND THE WORK

Built from the plant floor up.

His work spans controls architecture, PLC and HMI development, historian integration, industrial networking, virtualization, brownfield migrations, and national operations centers. That field background drives VALD’s operating doctrine: communicate directly, expose ambiguity early, and never hand operations a system the engineer cannot defend.

  • 20+ years in industrial controls
  • 27 software and toolset families used across project delivery
  • Plant-floor through enterprise architecture
  • Nationwide modernization and commissioning
  • Water, power, fuels, mining, and manufacturing
  • Forbes-published utility-modernization experience
INDEPENDENT RECORD

Three published cases. Direct source links.

01UTILITY MODERNIZATION
GE INTELLIGENT PLATFORMS / FORBES-PUBLISHED

End-to-end modernization across military utility systems in Alaska

The published case names Robert Maxfield as Doyon Utilities project manager and documents a phased modernization spanning power generation, water, wastewater, steam, natural gas, historian, and multi-site operations.

CURRENT ENGINEERING EVIDENCE

The history is published. The present work is measurable.

407legacy HMI screens reconstructed
42,998logic blocks made browsable
43,456points in an active migration census
7,046generated loop sheets

Current-project identity and configuration remain protected. The figures describe an active, anonymized municipal migration dataset and its generated engineering package.
