The Church of St. Michael the Archangel reached its next milestone this July with the installation of its new steeple. The steeple is a reconstruction of the original steeple based on archival photos of the civil-war era Church. The original steeple blew off the Church shortly after it was built, making its reconstruction an integral component of this Project.

The steeple is anchored to the structure with a series of bolts fastened through the octagonal base of the steeple and an octagonal angle frame designed by GNCB. The steeple is braced with chevron braces within its square base which is constructed with structural steel designed to accommodate the replicated tapering of the original steeple.

Phase 1 of the reconstruction of St. Michael Church will soon be completed. In addition to the installation of the steeple, the cold-formed steel shear walls are close to completion as the exterior cladding and stained glass windows are being installed. The east and west entrances and rear additions are in progress. Phase 2 of the project will include the interior fit-out and finishing of the Church.

This marks the second major milestone in the reconstruction of St. Michael. The first milestone, the raising of the first timber truss , was celebrated by the Parish with a truss-raising ceremony during which Bishop Michael Cote of the Diocese of Norwich blessed the first truss before its installation.

The original Church steeple blew off the structure shortly after its construction. The new Church will have a steeple replicated from archival photos.
Installation of the timber trusses – designed, fabricated, and installed by Vermont Timber Works – was completed this spring. The timber trusses are founded on new reinforced concrete piers to ensure their heavy concentrated loads do not transfer to the historic stone foundations.
The timber trusses are topped with structural insulated panels (SIPS). The SIPs transfer gravity loads to the trusses in addition to acting as the structure’s roof diaphragm. Lateral loads are transferred through the SIPs to the plywood-sheathed cold-formed steel shear walls.
The stained glass windows are a mixture of new and refurbished windows from the original Church.

Members of the Parish, Design team, and Construction team were given the opportunity to sign the center support of the steeple’s cross prior to its installation. Students from St. Michael’s school and Parish members were also allowed to sign the first timber truss during the truss raising ceremony.
The cross was installed by hand after the steeple was set using a crane and rigging.

GNCB attended the ribbon cutting ceremony for the Sayebrooke Village Elderly Housing Expansion project this month. The project broke ground earlier this year and now contributes an additional 15 units to the highly popular complex on Sheffield Street.

The buildings are a mixture of single- and two-story wood-framed structures on concrete slabs-on-grade. GNCB provide structural engineering and geotechnical engineering services for the project. The expansion was a Connecticut Housing Finance Authority (CHFA)-funded project.

Ms. Zoe Laird of Ohio has been hired as a Design Engineer at GNCB. Ms. Laird graduated from the University of New Haven (UNH) this May with a Bachelor’s of Science in Civil Engineering.

As a student, Ms. Laird was an active member of UNH’s student chapter of the American Society of Civil Engineers’ (ASCE) Concrete Canoe team, and was a member of the student chapter of the Society of Women Engineers (SWE).  

Ms. Laird’s senior design project was to design a four-story steel-framed boutique hotel with an underground reinforced concrete parking garage for UNH’s Hospitality and Tourism department. She performed much of the structural analysis and structural design for the building, and performed hand calculations to verify the computer model.

Past work experience includes an internship with the Ashtabula County Engineer’s Office in Jefferson, OH; tutoring entry-level engineering courses at UNH; acting as counselor for Camp GEMS (Girls in Engineering, Math, and Science) at Ohio Northern University; and several summers at YMCA Camp Fitch holding various positions including Tech Focus Counselor.

Amy Jagaczewski , GNCB Engineer, attended this year’s Association for Preservation Technology International (APTi) Conference in Ottawa, Canada . This year’s conference, themed CAPITALizing on Heritage, was a joint conference between APTi and The National Trust of Canada in honor of Canada’s 150th Anniversary. Approximately 1100 delegates from over 20 countries attended, including engineers, architects, preservationists, owners, historians, students, craftspeople, and technicians.

The APTi Conference offered professional development opportunities sorted into seven tracks depending on attendees’ backgrounds and interests. Ms. Jagaczewski attended presentations on the investigation, analysis, planning, and design of heritage structures as well as case studies on successful implementation of structural and preservation engineering principles. Topics directly corresponding with current GNCB work included reversibility of retrofits for exposed structural framing, management and assessment of historic coastal structures, and practices for analyzing unreinforced masonry buildings in moderate seismic zones.

The Northampton Community Arts Trust began occupying their newly renovated building at 33 Hawley Street in Northampton, MA this fall. The prefabricated metal building was originally built in the late 1980s and required structural upgrades to support the new use and energy-efficient design. The 25,000 square foot building will be used by the Trust to support education, rehearsals, and performances for varying forms of art.

GNCB provided structural engineering and geotechnical engineering services for this project during the initial investigation, design phases, and construction phases. Structural work included supporting new design features as well as addressing deficiencies in the existing gravity and lateral framing systems for modern loads. Geotechnical investigations included interior soil excavations to confirm the layout of existing foundations and subsurface characteristics for the installation of a new elevator pit.

Improvements to the roof framing involved the addition of 50-foot long steel trusses supported on new steel columns at the centerline of the building. The new steel off-loads the original steel bent frames to meet modern building loads and allow the installation of solar panels and a future suspended catwalk system for the black box theater. Steel x-braces were installed between the new and existing perimeter building columns to improve the building’s lateral system. GNCB also provided structural designs for the monumental stair and mezzanine and the new front entrance vestibule.
