Ms. Lee has over 30 years of experience as a Project Manager and Contract Manager including Owner Representation in the construction and engineering fields.  Her experience includes owner representation, construction management, project controls, audit assistance, site development, due diligence, claims management, and schedule preparation.   In addition, for 15 of these years, Ms. Lee spent her time in the field managing quality control, safety, subcontractor and client changes and claims, along with day to day operations of a construction project.

Her specific project experience includes power plants, water treatment systems, oil and gas mid-stream projects, remediation projects, computer chip plants (cleanrooms), pharmaceutical plants, data centers, and wireless site development. The projects ranged from construction only projects with difficult structural elements (spider trusses, building over a rock outcropping at a remote location, architectural concrete, strict baseplate tolerances) to major EPC (Engineer, Procure, Construct) projects ranging from $500 million to over $15 billion with complex mechanical and electrical systems and the associated performance guarantees.  Many of the commercial construction projects were fast track in nature including a new construction of a 50,000 SF Class 1 cleanroom. 

Ms. Lee not only is well versed in contract management, but also develops project specific procedures for procurement/subcontracting processes including material handling and execution plans.  The procedures strategize the proper commercial terms and cost structure for each scope of work and required flow downs from the prime agreement.  She has performed these services as both the owner representative and contractor. She successfully manages Change Management of subcontractors, suppliers, and clients by estimating proposed changes, auditing invoices and proposals, and verification of contract compliance making Ms. Lee a strong standard of care consultant. These talents have allowed her to successfully settle back charges and claims with subcontractors mitigating legal action; and to support project claims with client.

In one organization, Lori was key implementing good business practices into the Region’s Procurement System to control costs, forecast estimate to complete/at completion, and control cash flow. 

As a Project Manager, Ms. Lee planned and scheduled projects in conjunction with the construction team; performed site development activities including site acquisition with the associated feasibility studies of proposed sites incorporating budget and site marketability; oversight of engineering and design services; and oversight of permitting activities including NEPA, Phase I and II reports, and air space studies; and managed the close-out process consisting of punch list, operational turnover, and commercial close-out of procurements and documentation.
