Originally constructed as a nuclear decommissioning site, the Space Power Facility (SPF) is a NASA facility used to test spaceflight hardware under simulated launch and spaceflight conditions. The SPF is part of NASA’s Plum Brook Station, which is part of the Glenn Research Center. The Plum Brook Station and the SPF are located near Sandusky, Ohio.
The SPF can simulate a spacecraft’s launch environment, as well as in-space environments. NASA has developed these capabilities under one roof to optimize testing of spaceflight hardware while minimizing transportation issues. Space Power Facility has become a “One Stop Shop” to qualify flight hardware for human-crewed space flight. This facility houses three record-setting test devices:
Worlds largest vacuum chamber
Worlds largest vibration table
Worlds loudest room
PMC was brought in to laser scan and create high accuracy 3D models of the Mechanical Vibration Test Facility (MVF). The MVF is designed to simulate the vibration forces spacecraft endure when passing through the atmosphere. The 16 vertical actuators of the MVF allow for testing of up to a 75,000 lb (34,000 kg) article. The entire SPF facility supports the testing of substantial pieces of spacecraft. The MVF, in particular, must have custom scaffolding developed to prevent uncontrolled tipping of the test articles.
The goal of scanning and modeling was to virtually plan the assembly of fall arrest scaffolding for future vehicle vibration tests.
Over the years PMC has completed a lot of unique models but this was our first greenhouse and with a construction value of $22M this was not your typical greenhouse. Although mostly constructed out of curtain walls there were several elements within the greenhouse that were unique and required custom family development within Revit.
On a very strict timeline, our team completed the model and coordinated BIM issues for our customer Stuppy Greenhouse. The15,250 square foot greenhouse was an interesting model for our BIM team to develop. The model featured all major framing of the greenhouse, support systems such as fans, foundations, and specialty equipment all in a 13-day turnaround with very tight MEP integration into the space.
Working with Level Architects we were contracted to scan the 12 story 40,130 Sq. Ft. Building. Our work provided 3D Historical Revit Model Interior and Exterior. The project will be converted to Retail and Office space, maintaining Historical attributes. The building was scanned for dimensions and all Historic details Modeled for the lobby, mezzanine, stairways, and hallways, Offices were modeled for interior revision by Architects. Exterior Model will all details including rooftop assets.

A third-party supplier manufactures plastic automotive interior components for various automotive customers. The facility where this project was conducted comprises injection molding components, painting components and assembling part and sub-assemblies.
The objective of this study was to calculate operator efficiency for automotive and to categorize operator utilization as under-utilized, efficiently utilized or over-utilized/worked.
This facility operates three processes – plastics injection molding, painting of molded parts and assembly comprising of several parts and/or assemblies. The processes are split into various work stations.
Molding contains fifty-six different presses with tooling molds numbering three hundred and fifteen. Personnel allocation is one operator per press; in cases of slower production rates, a single operator manages two presses. A press operator’s responsibilities include packaging newly molded plastics into appropriate containers, processing those containers with the corresponding inventory labeling and readying containers of molded parts for placement in inventory by the logistics operators.
There are two separate lines for painting, considered as Paint Line 1 and Paint Line 2. Paint Line 1 is the larger of the two lines, in terms of the number of operators involved at the line. The painting line consists of six distinct processes or stages: loading of unpainted parts onto appropriate racks, wiping of loaded parts, unloading of painted parts, inspection of unloaded parts and packing of inspected parts; labeling of filled containers is a separate process that is independent from the paint lines (each paint line is independent from each other).
Assembly comprises over a hundred stations, each responsible for the assembling of a specific component or a sub-assembly. Each station has a personnel allocation of a single operator. A “spider” operator handles the labeling and container processes for several stations.
Since the focus was on operator efficiency, MODAPTS (Modular Arrangement of Predetermined Time Standards) was considered the most feasible approach. By assigning predetermined time standards to each of the captured operator’s motions for each station, a concrete cycle time without any non-value added activities can be determined.
The first phase consisted of videotaping each operator as they conducted their work, with emphasis on their motions. The second phase was to translate the captured motions into MODS or predetermined time standards – a total time to complete a set of motions without the presence of any non-value added activities. The third and final phase was to input the produced results into a proprietary process book.
After translating the captured motions into MODs, operational cycle time was determined by inputting the MODs into a proprietary Microsoft Excel process book. This process book takes the MOD values and translates them into a calculated time based upon predetermined standards. Then, based on the operational cycle time, along with a variable production cycle rate, daily production volume and production length (i.e. number of shifts per day or number of days per week, etc.), an operator’s efficiency was derived for a particular station. The calculated efficiency was then categorized into three distinct categories – the operator of a particular station was determined to be either under-utilized, optimally utilized or over-utilized.
Having determined an operator’s potential efficiency for any particular [assembly, painting operation, press and tooling] station based on an ideal cycle time and other dependent variables, personnel allocation can be forecasted more precisely. An operator with low utilization at a particular station could be otherwise used as an additional resource for another low utilization station. Likewise, a station that produces a utilization that is determined to be high [over-utilized] can be alleviated by adding an additional operator, thus distributing the high utilization of a single operator into two [or more] operators.
PMC’s customer needed to capture a high level of detail laser scanning in order to document existing historical elements. The scan data was used to record the features of a historic structure prior to its renovation. If at any time in the future there is an interest in returning the structure to its “original” state, the customer has documented the original features’ exact details and dimensions.
Organizations that are charged with preserving national monuments or historical buildings may commission “current state” scans to document conditions, then follow up with periodic scans, typically at 5-year intervals. Comparisons of successive scans often reveal indications of condition changes before damage becomes outwardly apparent. Also, when a structure’s site is prone to natural disasters (flood, earthquake, tornado), recorded scans can provide vital documentation for restoration efforts.
