Custom Excavating Examples
Wooden Dry Dock Dismantling & Demolition
Swan Island, Portland - 2009-2010
One of our more challenging projects was the dismantling and recycling of three timber Dry Dock in Portland. These were used by the U.S. Navy for ship repairs during WW2. They were condemned, then sat idle for over 50 years. The biggest question was how to dispose of them economically and efficiently. Many options were presented, from sinking them to explosion at sea, but dismantling and salvage was the best solution to a thorny problem.
Custom Excavating was awarded the contract to dismantle and salvage. The timbers were then made available for resale. The majority of the wood was taken out in sections as can be seen by the photographs below, enabling us to free up the costly berthing space quickly. The timber sections were then transported to another area on the property and dismantled by hand. The result was a safe and expeditious method of handing this project. Our team received high marks for safety (no injuries) and economy of time by meeting the owner’s schedule.
Wood Timbers salvaged from this project will be sold as resurfaced material. The non-salvageable residual wood was utilized as biomass fuel for a local saw mill. None of the material was taken to the land fill. Likewise, all of the steel fasteners are being recycled at a Metro Metals, a Portland Metal Recycler.
No. 10 Sixth Street Building
July-September 2011 $225,000
After a fire tore through most of The Cannery Café (No.1) and No. 10 Sixth Street Building in December 2010, Custom Excavating and Trails End Recovery worked together to safely demolish and recover over 550 tons of material. Both of these historical buildings were located on a pier on the water front of downtown Astoria, Oregon. This job involved maneuvering an excavator on the remains of a burnt pier; our skilled operators completed the task without delay.
These buildings were deconstructed and demolished in a very short time frame while at the same time maximizing the amount of material recycled. Custom Excavating and Trails End Recovery have many skilled operators that have extensive knowledge and training to accomplish any and all obstacles. We also hired many locals to help dig through debris to find the salvageable materials that were specifically requested from the community.
Custom Excavating and Trails End Recovery worked very hard to find those mementos that were sentimental to the community and the building owners. On this particular job Custom Excavating and Trails End Recovery hired four more people and worked with the local businesses for hauling, disposing, cleaning, hazardous material clean up and historic repairs.
We also have many different machines that are used specifically to work on deconstruction and demolition projects. These machines help with time constraints and amplify the amount of material recycled. Custom Excavating and Trails End Recovery worked very close with the city, contractors, and the building owners to maximize production while trying to recycle and recover as much material as possible. The building had many salvageable materials inside which were removed and sold as reusable material.
Site Clearing: Northwest Properties
Custom Excavating and Trails End Recovery work as perfect compliments for Site Clearing. We can clear and dispose of all on-site materials from whole trees to structures.
The new Warrenton Costco was the stage for a showcase project which was completed in 2009. We cleared over 50 acres of land, stripped the top layer of soil, removed the organic debris, stockpiled all of the topsoil for later use, dug all of the storm water retention ponds and processed all of the wood waste in just over three months, start to finish.
We have a high performance record in projects like:
- Nehalem 1996 Flood Project
- 2007 North Coast Storm Cleanup
- Warrenton Costco Site Clearing
- Camp Rilea in Warrenton
- Vernonia Sanitary Sewer Extension
We are currently on call for local area Emergency Disaster Relief.
Lewis and Clark School - 2002
Out of this project we were able top salvage the following materials:
- Gymnasium Bleachers - Cut into Trim
- Wood Beams - Re-sawn into useable lumber
- Concrete - Crushed into 3/4” minus material
- Bricks - Cleaned and made ready for sale
Salvaged Interior Fixtures:
- Playground Equipment
Virtually everything was processed by TER and made available for resale.
Pier #3 Demolition - Port of Astoria
Pier 3 at the southernmost end of the Port of Astoria enjoyed a rich and robust commercial trade since its construction in 1918. Custom Excavating was selected to do the dismantling and demolition of the old wooden structures in favor of more durable materials and pier design to accommodate a modern maritime business. Trails End Recovery took great care to salvage as much material as possible and is selling the water worn timbers with a certificate of authenticity.
The Port of Astoria remains a traditional working port which caters to maritime industries. As part of the renovation plan, the original Pier building was replaced by the Boat Haul-out Facility.
Current plans for the Pier #3 are to improve the ship side by driving sheet piles and filling in the void. this will enable the pier to service deep water vessels. This will enable the functioning of a log export operation, currently planned by Westerlund Log Handlers.
Astoria and Tillamook Safeway Demolitions
On both of these projects Custom Excavating and Trails End Recovery used local businesses for supplies and repairs and also trucking and hazardous material testing and clean up. Custom Excavating and Trails End Recovery hired local, out of work people, as we do on all out of town projects, to support the area of the job site. Both of these Safeways were buildings that we deconstructed. Custom Excavating and Trails End Recovery dismantled the buildings and were able to salvage many old timbers that went back to our warehouse for resale or custom milling. We used many pieces of equipment on these projects to ensure that we were under our time line constraints.
There were many other parts to the buildings that we were able to recycle such as metal, concrete, roofing, plastic and unusable wood. The salvaged metal was shipped to Portland, OR, the concrete was crushed and used on site as well as sold to the public. The roofing and plastics were separated and recycled either on site or brought to our facility. During both projects Custom Excavating and Trails End Recovery made it a point to work with the public and use local businesses. Both projects were a success, and completed on time and under budget. Ninety-five percent of materials were recycled.
Biomass Recovery: Astoria Steam Plant
Astoria is no stranger to Biomass use. The Astoria Steam Plant was constructed by PacifiCorp as a Biomass Fueled steam production facility. The steam turns a turbine and the turbine turns a generator. The end product was electricity. We find it poetically significant that we removed the old inefficient building and are now in the process of developing a new, modern biomass fueled power plant at North tongue Point.
It took about eighteen pounds of explosives, set at the tower’s base to bring all 210 feet of it to the ground. The charges were triggered at 7:08 a.m., crushing the tower's foundation and sending it into a heap of dust and debris.
The Astoria Steam Electric Plant was built in 1921, but out of use by 1970. PacifiCorp, Pacific Power's corporate entity, decided to destroy the plant in the year 2000. After over eight decades of service, the northwest veteran of electrical power production was brought down. The plant was located just 400 yards away from the existing PacifiCorp Substation. This was Pacific Power’s first Steam Plant and it was powered by Hog Fuel. This facility operated for some 50 years but was decommissioned due to inefficient burning and air pollution concerns. The problems were caused by no controls over the exhaust. Todays modern boiler systems have changed all of that. Biomass fuel is clean and safe and is economical as well.
Tongue Point Investors LLC are currently developing a 19.8 MW electrical power plant fueled exclusively from Woody Biomass. Click here to learn more about this.
