SES provides services in a variety of areas related to engineering and project management. Services are provided primarily by Demetrius Siachames as owner and operator of Sigma Expert Solutions. An overview of some of the services provided is provided below with links to associated line sheets.
Mr. Siachames, PMP is sought after as a Project Manager for multidisciplinary teams executing projects ranging from conceptual design to nuclear safety analyses. As a management consultant for facilities, he has generated documentation and analyses to validate mission need, scope, and schedule. He assists setting up project management processes and procedures to ensure DOE 413.3B requirements are met. In support of the DOE, Mr. Siachames has served as a part of independent cost estimating teams where he focuses on technical viability and risk analysis. He has regularly presented during program planning meetings and as an interface with regulators and key stakeholders. Mr. Siachames extended his interest in Project Planning and Analysis to develop a program capable of quantifying the impacts of risks and uncertainties on project schedules and budgets to supplement his project planning offerings.
Mr. Siachames has provided mechanical design services for products ranging from small precision components to large integrated systems. Examples include complex surgical aids, vacuum components, and large filtered ventilation systems. He maintains fluency with Soldiworks by regularly developing models to help clients visualize their problems, to design prototypes, and for internal projects. Coupled with access to a commercial grade Fused Deposition Modeling (FDM) printer, prototypes can be rapidly generated to test concept viability. Imagine how SES can help you get your design off the ground!
Mr. Siachames, PE has consulted in a wide range of industries including Commercial Nuclear, Government, and Medical Product Development. In the Commercial Nuclear industry he has performed margin assessment of safety class systems, evaluated anchorages for compliance with updated seismic requirements, and provided project management support for the Fukushima response. For Government entities he has served as Subject Matter Expert and Technical Lead in several DOE 413.3B reviews, led a team assessing disposition of DOE complex Special Nuclear Material, and served as a member of an Integrated Project Team as the technical expert in radiological ventilation and glovebox systems. In the Medical Device industry, he has reviewed designs for manufacturability, performed tolerance stack-up analyses, and created statistical tools to inform optimal manufacturing controls.
