LSL comparison

Orbit vs. CDM Smith

CDM Smith is a global engineering consultancy with deep water expertise. Orbit + DB Utility is operator-led: software AND replacement crews under one fixed-scope contract. Here's the honest comparison.

For: Orbit LSL

Category	Orbit	CDM Smith
Delivery model	Operator-led: software + crew structure under one contract. Fixed scope.	Consultant-led: study → design → bid → construction. Multi-phase, hourly engineering services.
Replacement crew	DB Utility crew structure stood up per project, licensed to your state.	Subcontractor selection typically separate phase; CDM Smith provides PM oversight.
Cost structure	Fixed-scope contract.	Engineering services billed hourly ($150–300/hr range typical).
Time from engagement to first dig	Single mobilization. Weeks to months.	Multi-phase. Months to over a year depending on project complexity.
Inventory software	Orbit LSL — purpose-built, integrates with WOMS for dispatch.	Trinnex / lead.it (CDM Smith subsidiary) — strong LSL inventory product.
Engineering depth	Built-in operations expertise. For regulatory-strategy or rate-case design, partner with engineering firm separately.	Best-in-class engineering. Regulatory strategy, rate cases, hydraulic modeling, treatment plant design.
Customer notification + state reporting	Built into Orbit LSL software, multi-state reporting.	Trinnex software handles this; CDM Smith provides regulatory advisory.
SRF readiness	Inventory + contractor under one contract — fast SRF deployment.	Strong SRF application support; longer mobilization to first dig.
When CDM Smith wins	Pick CDM Smith for complex regulatory engagements, hydraulic studies, treatment design.	When you need deep engineering services beyond LSL — master planning, rate cases, regulatory strategy.
When Orbit wins	When you have a defined LSL project and want fast, fixed-scope execution.	—
Built by	A national water-utility field-ops contractor.	Global engineering consultancy — ~5,500 employees, top-tier ENR ranking.

Notes: CDM Smith is one of the most respected engineering consultancies in the water industry. This comparison highlights the operator-vs-consultant delivery model difference. For utilities that need engineering services beyond LSL execution (master planning, rate cases, treatment design), CDM Smith is excellent. For utilities that have a defined LSL project and want fixed-scope inventory + execution, Orbit + DB Utility is the integrated offer. Many utilities use both — engineering for design, operator for execution. CDM Smith is a registered trademark of CDM Smith Inc.
