The carousel gazebo, a building project at Nemacolin by McMillen Engineering, preserves history through sustainable site development & landscape integration. BUILDING PROJECTS CAROUSEL GAZEBO AT NEMACOLIN PRESERVING HISTORY WITH MODERN DESIGN Nemacolin sought to create a custom-designed gazebo to house and protect a historical carousel, blending nostalgia with modern engineering. Our team was engaged to provide full land development services and prepare building permit plans, ensuring the structure was not only functional and safe but also a centerpiece attraction that enhanced the resort’s cultural and recreational offerings. Project Scope for Carousel Gazebo at Nemacolin: Structural design of gazebo to house historical carousel Electrical design for carousel operation and supporting systems Site lighting design for safety and ambiance Development plan and finished grading plan Stormwater management plan with narrative Erosion control plan with narrative Landscape plan to integrate the gazebo into the resort grounds HONORING THE PAST, ENGINEERING THE FUTURE The historical carousel required a protective structure that would preserve its integrity while inviting guests to enjoy its charm. Our structural design ensured the gazebo could withstand environmental loads while providing an open, welcoming aesthetic. Infrastructure That Enhances Experience We designed electrical systems to power the carousel and its supporting amenities, along with site lighting that balanced safety with atmosphere. The result was a space that feels magical at night while remaining fully functional and secure. Sustainable Site Development A finished grading plan and stormwater management plan with narrative ensured the site blended seamlessly into the resort’s landscape while responsibly handling runoff. The erosion control plan protected surrounding areas during construction, reflecting the resort’s commitment to environmental stewardship. Landscape Integration The landscape plan framed the gazebo as a focal point within the resort, using plantings and pathways to create a natural flow for guests. This integration elevated the project from a simple protective structure to a destination feature within the resort grounds. The Result The completed gazebo serves as a showcase for the historical carousel, preserving its legacy while providing guests with a memorable experience. By combining structural precision, thoughtful site planning, and aesthetic landscaping, the project demonstrates how engineering can protect history while creating new opportunities for enjoyment.

McMillen Engineering prepared a few design concepts for this road reconfiguration project at Nemacolin. Working on a strict timeline, this civil engineering project was completed on time with stunning results. CIVIL ENGINEERING GRAND ENTRANCE AT NEMACOLIN RESORT ENTRANCE REDESIGN During a routine meeting with this forty-year client, the owner stated how unfortunate it was that the Chataeu Lafayette was not visible upon its approach due to the configuration of the access road. At that time Nemacolin had two entrances from Route 40 that joined together before it reached the Chateau from the side. McMillen Engineering prepared a few design concepts that joined the two entrances into one and completely changed the entrance road alignment so that it approached with the Chateau in full view. Project scope for the Grand Entrance at Nemacolin: Base Mapping Preliminary Site Planning Final Site Land Development Planning Stormwater Management Planning NPDES Permit Preparation Utility Coordination Construction Engineering and Inspection CREATING A GRAND ENTRANCE AT NEMACOLIN Originally the parking garage was on a side road with entry at a lower level without any view of the hotel. Our new design provided a bridge directly from the entrance to the top of the garage, which added a full view of the Chateau upon arrival and a stunning view of the mountain upon departure. McMillen Engineering designed new access roads to the north of the main campus to be used by delivery vehicles and service staff. This design provided a concealed entrance, whereas previous deliveries and service access were mainly front of the house. Soon after the design was approved, it was announced that Nemacolin would host a portion of the Bachelorette television show. The client decided that the new entrance should be complete before taping of the show, which meant construction through the worst of winter. The harsh winter weather resulted in sub-zero temperatures on many days during the construction process. Because keeping the soil and concrete from freezing was difficult, heavy blankets were needed to keep the subbase soil from freezing before the concrete was poured. This method was necessary to keep the concrete from freezing before it properly set-up to the desired strength. This civil engineering project was completed on time with stunning results.

Secured funding from various state and federal funding programs for improvements along the historic National Road in Hopwood, PA between South Union and North Union Townships. CIVIL ENGINEERING CORRIDOR IMPROVEMENTS IN HOPWOOD, PA IMPROVEMENTS TO HISTORICAL CORRIDOR McMillen Engineering collaborated with various regulatory agencies, the Department of Transportation and individual property owners on the Village of Hopwood Corridor Improvements along the historic National Road between South Union and North Union Townships. The project resulted in a beautifully-detailed design complete with historic stamped sidewalks, historic lighting, gateway entry signs, planters and benches along the 2.1 mile length of roadway. McMillen Engineering also secured funding for the improvements from various state and federal funding programs. CORRIDOR PROJECT OVERVIEW The Hopwood Corridor sits along the historic National Road (U.S. Route 40) and is shared between two municipalities. The residents of Hopwood initiated a project to beautify this main corridor of their communities but wanted to maintain sensitivity to the history of the National Road. Each municipality supported the improvements provided that the properties along the corridor were not adversely affected. McMillen Engineering served as the civil engineer and conducted monthly public meetings to allow residents and elected officials the opportunity to provide input on each aspect of the project — from conceptual design through construction. Since the completion of the project, the enhancements along the corridor have been maintained by the Townships, volunteers who reside in Hopwood, and business owners. Various organizations have held events along the corridor which have provided opportunities for the improvements to be showcased. South Union Township even decided to develop a park at the end of the improvements in remembrance of Supervisor Frankhouser who was committed and dedicated to the corridor project.
