Infrastructure advisory, project development and finance

Mitchell Langley Advisory / Langley & Villalobos Advisory Ltd.

• Advise 15+ clients across transportation, energy, telecommunications and legal services on project structuring, public funding, regulatory compliance and capital investment decisions.
• Evaluated an electric bus fleet and charging infrastructure financing request for a project financier, identifying land-use, site-control and fleet-performance constraints and inconsistent financial assumptions. The financier declined to proceed.
• Analyzed an operator’s existing financial model for a design-build-finance-operate-maintain (DBFOM) concession, designed four sensitivity cases and led due diligence responses to a development bank and prospective equity investor. Both made financing offers.
• Built two 12-month service-delay scenarios covering fleet lease payments, maintenance and storage costs, and presented the exposure analysis to the regulator. The regulator allowed full government-backed monthly fleet payments to begin with partial service.
• Reviewed fleet replacement subsidy selection criteria against mandatory retirement requirements, calculated additional funding needs and prepared a brief on the regional government’s authority to prioritize the city’s buses.
• Conducted zoning and land-use due diligence for proposed transit infrastructure sites. Findings on prohibited uses, environmental restrictions and the timing of administrative remedies enabled the client to withdraw from acquisition negotiations without penalty.
• Manage public procurement bids and serve as authorized representative for operators in 50+ administrative enforcement and appeal proceedings and 250+ formal regulatory matters.
• Build automated dashboards and AI-supported decision tools for operational, financial and regulatory monitoring.
