Our project management staff understands your needs and how to work with your budget and architectural drawings; we will assist you in ensuring a successful project. Another unique feature of Trillium Dell is our willingness to work with your site needs. Over the years we have been asked to execute hand raisings involving large numbers of participants, crane raisings with volunteers. Timber Frame raisings are exciting and complicated, our specially trained staff can work with and your crew of carpenters or crew of volunteers to install your frame.
Most of our commercial and public work is unique and often complex, involving multiple trades, long distances, materials which are difficult to source, logistics, difficult engineering, and a tight timeline. You can expect to receive timely shop drawings, stamped final drawings, a knowledgeable and courteous staff, prompt response and an exceptional product. In some cases we will provide a frame or structure for your site carpenters to install, in these cases you can expect to receive a set of drawings with the installation sequence in addition to the shop drawings.
Multiple species are available for these types of structures, though typically we use white oak, southern yellow pine or Douglas fir. Douglas Fir and Southern yellow pine are relatively equal regarding their engineering value, white oak runs a close third, though generally with longer spans we incorporate a softwood in as a lower chord member in larger trusses. Here at Trillium Dell we operate our own machine shop and offer a multitude of engineered hardware and brackets for your project. We offer hardware and brackets in stainless steel, hot dipped galvanized steel, and painted steel. We do utilize quite a bit of technology from Europe, such as various types of hangers, flitch plates, and threaded tensioning systems, and we will help you and your engineer or architect when it comes to using products such as these.
Any form of timber is available for our projects as well, round logs, hewn logs or timbers, cruck frames, curved timbers, halved and quartered timber for wrapping steel columns and beams, and sawn timber with a variety of timber frame finishes. Grade of log is usually select structural and dry, grade stamping is provided on request and available in the form of a certificate and physical stamps on individual timbers.
