Featured Projects
Mission Imaging Inc, 1200 Nevada Street
Client: SP Drafting
Location: 1200 Nevada Street
Redlands, CA. 92374
Surface area: 3400 SF
The 1200 Nevada Street project involved a significant tenant improvement focused on the installation of MRI imaging equipment and an X-ray machine in existing Suite #101. Our team provided a comprehensive MEP design tailored to meet the specific needs of this medical facility. The mechanical scope included thorough load calculations using Trace software, ensuring optimal space heating and ventilation in compliance with code requirements and client specifications. We also developed detailed drawings, mechanical equipment schedules, and incorporated plan check comments to ensure that all aspects of the mechanical design aligned with regulatory standards.
In the electrical scope, we created a precise single-line diagram along with power plans that addressed circuitry distribution and mechanical equipment power needs. Our lighting plans featured a comprehensive distribution of fixtures, lighting schedules, and circuitry assignments, all designed to enhance the operational efficiency of the medical suite. Additionally, we conducted load analysis and prepared panel board schedules and riser diagrams to ensure a robust electrical infrastructure.
The plumbing scope encompassed detailed fixture unit calculations, utility coordination, and the design of domestic and sewage pipe layouts. We meticulously reviewed existing drawings and created schedules for equipment and rough-ins, supplemented by riser diagrams. By addressing plan check comments throughout the process, we ensured that all plumbing systems were optimized for performance and compliance. This project exemplifies our commitment to delivering high-quality, tailored MEP solutions in the healthcare sector.
The deliverables included a Revit model, foundation plan, floor framing plans, roof framing plan, and a complete set of structural details, notes, and specifications. Using RFEM 6 finite element analysis software, we performed an in-depth analysis to design all load-bearing and framing elements, adhering to both ultimate and serviceability limit states. This thorough approach ensured that every component, from foundations to columns, beams, and rafters, met the highest standards of safety and durability, providing a solid structural solution tailored to the project’s needs.
