UCSC Hay Barn Raising - Part Two

The Hay Barn was raised in three stages over the course of the weekend: first the lower-tier timber frames were positioned and secured. Followed by the upper-tier timber frames and finally the addition of the rafters.

A crew member on the ground, delivered hand signals to the crane operator, as he raised and lowered each of the 11 lower-tier timber frames. The timber frames were lowered onto sill plates, some portions of which had been salvaged from the original 1860’s Hay Barn. The timber members were joined together by interlocking mortises and tenons, then secured by hand crafted wooden pegs.  By mid afternoon on Saturday the first stage was complete.

Following lunch the timber framers began adding the upper-tier timber frames, which consist of the straining beam, purlin posts and counter braces. Working on top of the lower-tier the crew carefully balanced on temporary catwalks and beams. Coordinating between the ground crew and the crane, the craftsmen secured the upper-tier timber frames, demonstrating incredible dexterity. 

The third and final stage was the addition of the rafters and ridge beam members. This was carried out on the Sunday afternoon, by both qualified timber framers and volunteers. The ridge beam members were added after every sixth rafter had been secured. By the end of Sunday all the timber framing was complete, bringing us one big step closer to a restored Hay Barn.

UCSC Hay Barn Raising - Part One

This past weekend, timber framers from around the state descended on Santa Cruz to assist in the raising of the Hay Barn. Once the scaffolding was assembled, work began in earnest. Beginning at the south end of the barn, the timber frames were meticulously lowered into place one by one via crane. A combination of qualified timber framers and community volunteers secured the wall posts into the sill plates and guided wall girts into their pre-prepared mortises. Hand-crafted wooden pegs secured all the members in place. Seeing salvaged Hay Barn members be reused, although sparsely, was very rewarding.

1908 Shattuck - Construction Update 2

The shoring for the PT Deck at the 1908 Shattuck construction site has now finished. All of the formwork from the pour last week is still standing. It will remain until the second floor slab's shoring comes down after the pouring of the PT deck in a months time. From the second floor just the Nelson studs can be seen standing proud of the PT deck.

1908 Shattuck - Installation of the Base-Isolator Columns

This morning once again the 1908 Shattuck construction site was the place to be in Downtown Berkeley. People put their morning commutes on hold to watch as the Base-Isolator's and Column Tops were hoisted from the truck by crane and carefully lowered onto the site. From there one by one they were positioned on top of the existing columns.

UCSC Hay Barn - Preparing the Frames

With under three weeks of production to go, the crew at Santa Cruz Timber Frames is working briskly. This model sits outside, amidst the workers, serving as a reference tool for planning the assembly of the Hay Barn. The photographs below also show a series of tenon templates, which are used to make sure each mortise is perfectly consistent.

This model, made by Dos Osos Timberworks, serves as a reference for the timber framers.

A girt tenon template.  Girts run the length of the Barn, connecting each of the bents.

This shortened, portable wall post template includes the top tenon, tie beam mortise, and bottom tenon.

Once a tenon is completed, it's coated in wax to ease the assembly process.
