LDG’s Stefanie English, PE, recently co-presented at the inaugural Residential Building Design & Construction Conference, hosted by Penn State’s Pennsylvania Housing Research Center (PHRC). The conference took place February 20-21, 2013 at the Sands Casino Resort in Bethlehem, PA. Read the presentation she developed in conjunction with Bill Brown, “An Introduction to Steel and Concrete Modular Construction”, below.
ABSTRACT
For many years, wood framed modular construction has been a useful and cost-effective solution in the residential market. While this type of construction has been a good solution for one- and two-family residential construction, it has been limited by factors such as available beam spans, lateral force resisting system requirements, and fire resistance, affecting its use in larger multi-story projects, such as hotels and dormitories. This presentation will explore the benefits of using steel-framed modules to achieve greater exterior opening distances, increased floor plan flexibility, LEED® certification, and non-combustible occupancies.

Piollet Mansion, 1950′s
A few months ago Randy Williams, the head of Dandy Mini-marts, came to me and said “I have a really great project for you Dave.” He began to explain how he recently acquired the old Piollet House, a historic Mansion and landmark in Bradford County, PA, and wanted to convert it into a new Dandy store. Dandy is one of our Brand Architecture clients and we’ve worked closely with them on many stores in the past, but none like this. I was pleased that we were given the opportunity, but I also knew the challenges associated with such a big undertaking. However, I shared Randy’s enthusiasm and appreciation towards this historic building and was eager to begin work.
Here’s a little history on the building… > Read the rest of this article

Maybe you’ve seen these before but I was pleasantly surprised by the creativity and simplicity of this project and had to share it. The mice’s ears are almond slices and their bodies are chocolate covered cherries – the rest is pretty simple. Donna explained that these are fun projects to do with kids of all ages (and adults too). We’d love to hear about creative projects that get your family engaged in design over the holidays.

Recently, we’ve been involved in a unique restoration project in Wysox, PA for Dandy Mini Marts. The project involves the restoration of a local landmark; the old Piollet House. I’ll be devoting a series of upcoming posts that will provide further insight into this exciting project. The following video segment features WVIA’s Bill Kelly interviewing Dandy Mini Marts’ Randy Williams and provides some excellent background on the project. Stay tuned…

On July 12, 2011, a historic truss was set in its new location at 4th Street over the Allegheny River in Coudersport. The truss had spent the past 127 years three blocks upstream at 7th Street, carrying traffic to the Borough’s northeast corner and recreation park facilities. The historic bridge will now continue its service life as a pedestrian bridge at its new location.
The 7th Street Bridge was built in 1883 by the King Bridge Company of Cleveland, OH. The bridge is unique because it is one of the first bridges to be built entirely of steel and to still be in service. The bridge was retrofitted in 1983 with the addition of the steel arches. The decision to replace the bridge was made by the borough because it was functionally obsolete. The bridge was a one lane bridge that lacked adequate vertical clearance, proper barriers, or a sidewalk to provide access for pedestrians using the park.
