Slayden’s positive approach and eagerness to achieve the project goals was a tremendous benefit and a driving force to the project and its success. Slayden achieved all minority, woman, and emerging small business subcontracting goals and also met the 20% Workforce Training and Hiring Program’s apprenticeship requirements. They also held their subcontractors to these same goals and requirements.
