Frequently Asked Questions
Our clients commonly ask these questions about our contract engineering services.
For additional information, please contact our engineering team directly.
We can begin with various levels of input—from rough concept sketches to detailed specifications. For optimal results, providing information about intended function, operating environment, target cost, production volume, and any design constraints helps us create appropriate solutions. Our team asks targeted questions during initial consultations to gather necessary information, making the process straightforward when you have limited technical documentation to start.
We treat all client designs with strict confidentiality, protected by formal non-disclosure agreements. Your intellectual property remains yours, we make no claims to designs created under contract. We maintain secure design servers, limited access protocols, and can compartmentalize projects when needed. For clients with specific security requirements, we can implement additional protective measures to safeguard sensitive information.
Yes, we regularly work with existing designs in various formats. Our team is proficient with major CAD systems and can convert files between formats when needed. We can modify, improve, or expand upon existing designs, create manufacturing documentation for conceptual designs, or update legacy drawings to modern standards. If you have partial designs or older documentation, we can integrate these into new, comprehensive design packages.
Project timelines vary based on complexity, ranging from 2 to 3 weeks for simple components to several months for complex systems. After initial consultation, we provide a detailed project schedule with key milestones. We prioritize communication throughout, providing regular updates and immediately addressing any timeline changes. For urgent projects, we can often allocate additional resources to meet compressed schedules. As a contract engineering firm with in-house manufacturing in Hanover, PA, design-to-first-article timelines are typically 30 to 50 percent shorter than working with separate engineering and manufacturing firms.
We manage design changes with a structured revision control process. Minor refinements during development are part of our normal workflow. For significant changes after design approval, we implement formal change orders to document modifications, assess impacts on schedule and cost, and maintain clear records of design evolution. Our documentation system tracks all changes, providing complete visibility into the design history and rationale for modifications.
