Mandy’s practice focuses on the representation of owners, design professionals, developers, and contractors throughout the construction process. Her experience includes contract drafting and negotiation, contract administration, and litigation or alternative dispute resolution of claims for delay, impact and acceleration, design or construction defects, and mechanics lien foreclosures.

She spent almost ten years in the field supporting a large utility client on a series of multi-billion dollar complex construction projects, providing legal services including contract negotiation, contract management and administration, project execution, claim avoidance, and dispute resolution through on­site assistance with the client’s day­to­day review of contracts, change orders, and other commercial issues. Additionally, her experience includes assisting regulated utilities develop a prudence strategy for rate-making regulatory proceedings.

Procurement/Contract Negotiation

Mandy has negotiated multi-million dollar construction contracts utilizing various contracting methodologies and project delivery systems to fit the client and project. Her transactional experience includes all aspects of the competitive bid procurement process including assisting clients to develop Request for Proposal documents, planning and executing pre-bid meetings, assisting the project team in responding to bidder questions, analyzing legal and commercial aspects of bid responses, and contract negotiation. Additionally, she has assisted clients in revising form contract documents and procurement­related processes and procedures that address the project’s needs, the client’s needs, and industry best practices. She also has experience providing training to project engineers, contract managers, and procurement personnel regarding procurement-related policies and best practices for project documentation and contract administration.

Contractor Claims/Dispute Resolution

Mandy advises owners of long-term projects regarding industry best practices and strategies for claim avoidance and resolution of contractor claims and disputes in a timely manner during the project to eliminate or mitigate any disruption to work in the field. She has worked on-site with clients regarding commercial correspondence management, change order analysis and contractor claim resolution,  project reporting, contract enforcement, warranty enforcement, and providing legal advice to the project team on a daily basis.

Regulatory Consulting

Mandy has experience supporting and advising a regulated utility regarding the recovery of construction costs in a ratemaking proceeding. This includes assistance to the project team and corporate executives regarding appropriate documentation for project costs including budget variances, executed change orders, and contractor claim settlements. She also advises utility owners regarding witness preparation, attorney-client privilege issues, confidentiality of commercially sensitive project documentation and related regulatory testimony/filings, drafting written testimony for state regulatory proceedings, and drafting and responding to data requests. She has also evaluated the rate making trends in the United States and Canada for pre-approval of project costs.

  • Experience

    • Iatan Project: Provided on-site day-to-day legal support to the owner's project management team regarding contract negotiation, contract administration, and dispute resolution throughout the life cycle of the project for the purpose of maximizing financial and operational performance (i.e. cost and schedule control) and minimizing legal risk. The Iatan Project included the construction of a new 850 MW (net) supercritical, pulverized coal unit that burns Powder River Basin (PRB) coal. The new unit included emissions control equipment that met the Best Available Control Technology (BACT) standards, including a selective catalytic reduction system (SCR) for NOx control, a wet flue gas desulfurization system (“Scrubber”) designed to use a limestone slurry solution for SO2 control, and a pulse jet fabric filter (“Baghouse”) for particulate control. Additionally, a powdered-activated carbon system was installed to remove mercury. The project received recognition by Power Magazine as 2011 Plant of the Year.
    • Developed the regulatory strategy for construction of Iatan Unit 2, drafting the pre-filed testimony and associated data request responses, providing significant witness preparation support, and drafting the post-hearing brief for construction prudence issues in rate making hearings before the Missouri Public Service Commission and the Kansas Corporation Commission. Based on the strength of the construction project documentation and evidentiary presentation in the rate case, both states only disallowed approximately $20 million (or approximately 1 percent) of the Iatan Unit 2 project costs from rate base.
    • Obtained an arbitration partial award of over 91 percent of the owner's costs in a multi-million dollar construction dispute.
    • LaCygne Environmental Retrofit Project: Provided on-site day-to-day legal support to the owner's project management team regarding contract negotiation, contract administration, and dispute resolution for an environmental retrofit of two existing units composed of a coal-fired unit nominally rated 810 MW gross that uses a supercritical, cyclone-fired boiler (Unit 1) and a pulverized coal-fired unit nominally rated at 715 MW gross that uses a subcritical, wall-fired boiler (Unit 2).
