A Pittsburgh machine shop with an engineering background
Three Rivers Precision lists its address as 230 Auburn Street, Pittsburgh, PA 15206. On its official background page, Sean Handerhan and Sinjon Bartel explain that they started the business around their interest in manufacturing. Their published biographies describe mechanical-engineering backgrounds and experience in production, fabrication and electromechanical work. These are statements from the business, rather than interviews conducted by The Pittsburgh Wire or an independently reconstructed founding history.
That engineering background provides context for the type of enquiry a prospective customer might bring. Someone developing a first component may need to discuss whether the available information is sufficient for an estimate. Someone replacing a known part may instead have an approved drawing and an established inspection requirement. Explain the situation accurately, including any unresolved design choices, rather than assuming a machine shop will infer the intended function from a file name or a photograph.

Contract work, prototypes and mechanical assembly
The published services page distinguishes contract manufacturing, prototype machining and mechanical assembly. It names applications such as brackets, camera mounts, heat sinks, electrical enclosures and custom fittings, and describes assembly involving items such as inserts, pins and bearings. That list gives readers examples of the operator’s stated scope; it is not a complete inventory of accepted jobs, available materials or current capacity.
For a bracket or mount, a useful discussion identifies the mating parts, important interfaces and whether the component is a prototype or intended for repeat supply. Ask what drawing information is required before a commitment can be made. If an assembly includes bought-in items, distinguish those items from the parts to be manufactured. This helps prevent an estimate for one component from being mistaken for a quotation covering an assembled and inspected product ready for installation.

Quality information and project acceptance
The company homepage identifies the operation as a CNC machine shop and publishes a link to quality certification information. Readers who need a particular quality requirement should examine the current document and confirm its scope, site details and validity directly with the company. A homepage statement should not be treated as a substitute for the supplier review required by a customer’s own procurement process.
It is also useful to distinguish a supplier’s quality system from the inspection requested for a particular job. Ask what measurements or records will accompany the parts and who approves any departure from the drawing. If a first article is expected before a larger order, include that step in the agreed scope. Keep revisions attached to the correct batch so a successful early sample does not become ambiguous when the design, quantity or material changes later. These are editorial purchasing suggestions, not additional published company policies.

How to contact the shop
The official contact page directs enquiries and quotation requests to hello@threeriversprecision.com and lists telephone 412-806-1776. It repeats the Auburn Street address. Use those published channels to confirm the right contact for a project, arrange any visit and ask how technical files should be delivered. The directory does not establish that the facility accepts unscheduled visitors or provides an immediate over-the-counter machining service.
Before the first exchange, prepare a brief explanation of the part, desired quantity and requested delivery condition. Separate a drawing ready for quotation from a concept still under development. If an existing part is being used as a reference, clarify whether the customer has authority to reproduce it and whether an approved specification exists. End the conversation with a concrete next step: which information is missing, who will provide it and what decision follows. That is more useful than treating an introductory email as an accepted production order.
A repeat order should identify whether the original specification is still current. If the customer has changed a mating component, coating or assembly method, explain that change even when the requested part number looks familiar. A clear revision record supports a more useful supplier conversation.
