Campaign Exceeded Goal by More Than $5 Million
WASHINGTON, D.C.(Feb. 4, 2016) – The Land Trust Alliance, a national land conservation organization working to save the places people love by strengthening land conservation across America, today announced the completion of its first campaign, which raised $40.1 million in new funds. The total is more than $5 million above the campaign goal.
“It’s of course a wonderful thing to celebrate the fact that we overshot our goal by over $5 million,” said Frederic Rich, campaign co-chair and vice chair of the Alliance’s board of directors. “Forty million dollars is an impressive achievement for an organization of this size. But frankly, it’s not the money that matters. It’s what we were able to do with this money.”
Used to increase the pace, improve the quality and ensure the permanence of land conservation, campaign funds were reinvested as they were received across five years. The resulting initiatives – such as making permanent a federal tax incentive for land conservation and establishing the Terrafirma Risk Retention Group – have transformed the entire land trust community.
“The title of this campaign was Together: A Campaign for the Land,” Rich said. “The Alliance itself is all about having the nation’s 1,700 land trusts think of themselves as together in a single, national movement. Every land trust itself is all about a community coming together to save the places that define them. And those places that we save, those are places where people come together and where their differences seem trivial. So if you ask me how we succeeded in this campaign, the answer is absolutely the same: We succeeded because we did it together.”
Leaders of land trusts across the United States already appreciate the differences the campaign has made. Nicole Byrd, executive director of Solano Land Trust in California, said the Alliance “invests in all of us and they are genuinely invested in our success.” And Christine Johnson, president of the Conservation Foundation of the Gulf Coast in Florida, described the Alliance as her “go-to place for making sure that I am doing all that I can to save the land we cherish so much.”

Campaign leaders included: David H. Anderson, honorary chair; Michael P. Dowling, campaign co-chair; and Frederic C. Rich, campaign co-chair. The campaign cabinet included: Robert A. Ayres; Alan M. Bell; Lauren B. Dachs, campaign vice-chair; Peter O. Hausmann, chair of the National Council; Sherry F. Huber, campaign vice-chair of regional committees; Ted Ladd, campaign vice-chair; and William Mulligan.
Regional campaign committees included chair Ted Ladd, Lisa Cashdan, Scott Dickerson, Jameson S. French, Sherry F. Huber, Laura A. Johnson, Mary McFadden, J.D., Nicholas J. Moore, Julie Sharpe, Steve Small and Peter Stein for the New England region; co-chairs Peter O. Hausmann and Frederic C. Rich, Christopher E. Buck, Marjorie L. Hart, Alice E. Hausmann, Tony Kiser, Fernando Lloveras San Miguel, Caroline P. Niemczyk and Michael A. Polemis for the New York/Mid-Atlantic/Puerto Rico region; co-chairs Alan M. Bell and William Mulligan, David Hartwell, Kathy K. Leavenworth and Judith Stockdale for the Midwest region; chair Lauren B.

In-line ramming tool cradle maximizes energy transfer in pipe ramming extraction technique
January 28, 2016 – LAKE MILLS, Wisc.– Pipe ramming tools from HammerHead Trenchless Equipment can now be locked inside a wide range of ready-made extraction cradles manufactured by the company. The extraction cradles, sometimes referred to as “canoes,” enable horizontal direction drilling (HDD) contractors to orient a ramming tool 180 degrees to extract stuck pipe or tooling, assist in product pullback and remove washover casing at the end of the HDD job. Extraction cradles also give pipeline installers the most effective means to slick bore and install cathodic protection (CP) pipe.
Unlike fabricated offset mounts that lose a significant portion of ramming energy laterally, an extraction cradle is mounted directly in line with the pipe or tooling. This alignment transfers impact force from the ramming tool to the pipe or HDD tooling with maximum efficiency.
Compared to other mounting methods, using an extraction cradle means more work gets done, while eliminating time and labor – hours, sometimes days – of fabricating a mounting system.
Alan Goodman, a Global Sales Manager for HammerHead Trenchless Equipment, said the ready-made extraction cradles are reusable and highly versatile. A single cradle can also accommodate a range of both pipe and hammer sizes.
“For instance our 36-inch extraction cradle can mount to 36-inch casing on one end and a 30-inch casing on the other end,” Goodman said. “Then it can be modified further to address other casing sizes by using standard pipe reducers. This means the same cradles can be used with our 26-inch, 24- or 20-inch hammers.”
Slick boring pipeline
One of the most exciting uses of the extraction cradle is in a trenchless pipeline installation method called “slick boring,” an effective, safe method of installing pipeline products, which are routinely protected by a coating supplemented with cathodic protection (CP). A CP system protects a wide variety of metallic structures from corrosion in various environments unless it is compromised.
To install a coated-lined pipe with a pipe ramming tool, a slick bore contractor simply drives a sacrificial, standard casing as a “dummy” into the ground with conventional pipe ramming technique. The contractor removes the ramming tool to place it in the extraction cradle, which has been mounted at the other end of the pipe.
The contractor welds the new coated-lined pipe to the dummy casing that was initially rammed into place. As the hammer locked inside of the cradle extracts the dummy casing from the ground, the dummy casing pulls the coated-lined pipe into place. Slick-boring method limits stress or damage to the pipe or its coating, since they are never subjected to direct impacts from the hammer. The dummy casing, which takes the brunt of the impact force as the casing cuts and drives the casing forward, can often be reused for additional slick boring jobs.
HDD completion insurance
Having an extraction cradle and hammer on hand during challenging HDD operations helps to assure the contractor of completion. “Stuck pipe or tooling is an urgent situation,” Goodman said. “Since there is little fabrication or welding needed, the contractor begins efforts to save the bore, pipe, or tool string as quickly as possible.”
Minutes make the difference in such cases, Goodman said. “There’s no 100 percent guarantee that ramming a stuck pipe or drill stem will save a job. While it’s definitely the best technique available for getting them moving again, the chances of saving the bore hole and freeing pipe or tooling go down with the length of time they remain in the ground. If the contractor doesn’t have a standby extraction cradle and hammer, HammerHead Trenchless Equipment will rush one of each to the site immediately upon getting the call for help. We can also have a technician there on site with them.”
Removing washover casing
HDD contractors drive washover casing to reach more favorable drilling conditions, isolate drilling operations from the formation, protect circulation, and ensure maximum recovery of fluids. Pipe ramming tools mounted in extraction cradles are an effective means of extracting the washover casings at the end of the job.
The HammerHead Trenchless Equipment extraction cradle comes in a variety of sizes and is available from HammerHead Trenchless Equipment or from authorized dealers, worldwide. Authorized dealers can be found on the web at www.hammerheadtrenchless.com or by calling 800.331.6653. (International: + [1] 920.648.4848).
