Description

At Horrocks, we believe the best work comes from companies with values, that our people are our greatest resource, and that we have a responsibility to the communities where we live and work.

Role Summary

Serve as a project engineer on multi‑discipline water resources projects, owning scope, schedule, budget, quality, and risk from planning through construction support while delivering client value and stakeholder satisfaction.

What are the core responsibilities for the role?

• Project Planning & Work Plans: Develop project execution plans, scopes of work, and phase plans; tailor delivery approach (predictive, agile/hybrid) to context while focusing on value delivery and outcomes.
• Scope, Schedule, and Budget Control: Establish baselines; monitor progress; apply change management; maintain earned value/cost/schedule reporting appropriate to project scale. Follow Company change management procedures and delegation of authority (DOA).
• Risk & Opportunity Management: Identify, analyze (qualitative/quantitative), respond to, and monitor risks; proactively escape issues and capture opportunities.
• Stakeholder & Client Engagement: Map stakeholders; maintain transparent communications; lead meetings and presentations; manage expectations and decisions.
• Quality Management (QA/QC): Plan and execute design reviews, interdisciplinary checks, model reviews, and constructability reviews; maintain document control and versioning.

• Hold paramount the safety, health, and welfare of the public; practice only within areas of competence; act as a faithful agent to the client; maintain honesty and integrity in all communications.
• Comply with applicable laws, codes, standards, and permitting requirements; identify constraints and assumptions transparently.
• Avoid expanding obligations beyond insurable standard‑of‑care language unless expressly negotiated (e.g., “best,” “highest,” or “ensure” may inadvertently elevate liability).
• Document key decisions, design bases, and limitations (including data gaps and uncertainties such as those arising from climate, geotechnical, or hydrologic variability).
• Follow the firm’s Quality Management Plan (QMP)
• Plan checklists and hold‑gates for calculations, models, drawings, and specifications; incorporate independent technical reviews and interdisciplinary coordination.
• Ensure traceability of inputs, assumptions, and revisions; manage document control per project standards.
• Pursue continuous improvement via audits, corrective actions, and client feedback; use metrics to assess process effectiveness.
• Plan, design, and analyze water transmission, storage, and distribution systems; wastewater collection systems; and pump stations.
• Perform hydrologic and hydraulic analyses; prepare drainage studies, master plans, and feasibility reports.
• Develop plans, specifications, and engineer’s estimates; support permitting across jurisdictions.
• Build and calibrate system and network models; evaluate alternatives; support value engineering and constructability reviews.
• Coordinate field data collection, condition assessments, and utility investigations
• Lead and mentor other team members, engineers and designers; foster collaborative, inclusive teams across disciplines and offices.
• Coordinate with clients, agencies, and subconsultants; support pursuit efforts and proposals, including scopes, schedules, budgets, and presentations.
