Construction Software Companies & Consultants in Franklin, WI

Seiler Instrument Geospatial is a fourth-generation, family-run business that sells, supports and services the hardware and software used by construction contractors, land surveyors, engineers and mapping/GIS teams. Its Franklin office serves buyers in the greater Milwaukee area. The company's main role is distributing Trimble technology, and it describes itself as one of the larger authorized Trimble distributors in the Midwest.

It also resells products from other vendors, so a contractor can source field equipment and the matching office software from one supplier.

Products and Software

Seiler's catalog covers the whole chain from measuring on site to working with the data in the office. Buyers comparing construction software vendors will find that it pairs software with the instruments that collect the data. Its main product groups include:

• Field and office software for survey, layout and data processing
• Optical survey instruments, including robotic total stations such as the Trimble S7
• GNSS positioning receivers and handheld data controllers
• 3D scanning systems and drone platforms
• Mapping/GIS tools and utility survey systems

Besides Trimble, the company lists Spectra, DJI, Esri, Autodesk and GeoBridge among the brands it is authorized to resell. This lets it put together packages that connect field data collection with design and GIS work.

How It Works with Clients

Seiler says it matches tools to the workflow each customer already uses, aiming to make crews more efficient and projects more profitable. One customer testimonial on its site describes a robotic total station used for topographic work, boundary surveys and construction staking.

According to the customer, a task that once needed a two-person crew could be done by one person in less time. The company backs purchases with a satisfaction policy and publishes technical tip videos every month to help users get more out of their equipment.

It also hosts regional events such as customer appreciation days and an annual technology day in Wisconsin, where clients can try new equipment.

The Franklin Office

The Franklin location has a showroom with equipment on display, sells supplies, and offers training and support. It also has an in-house service department that repairs most instruments and is certified as a Trimble Authorized Service Provider. The wider service network handles both warranty and non-warranty repairs, offers free estimates, and aims for quick turnaround on survey, GNSS and GIS equipment.

Background

Eric H. Seiler founded the company in St. Louis in 1945. He had trained in fine optics at the Zeiss school in Jena, Germany, and the business marked its 80th year in 2025. Headquarters are still in St. Louis, and the geospatial division runs regional offices in several Midwestern states, including Wisconsin, Illinois, Indiana, Michigan, Kansas, Nebraska and Kentucky.

In late 2022 it grew in Kentucky by acquiring the assets of Precision Products. Buyers who want a long-established local dealer with Trimble-certified repair, hands-on training and both field hardware and construction software may find it a good fit.
