Slow in the Go

Barrie, Ontario's long-awaited Site 41 Landfill project is finally moving forth with construction. Slowly. In addition to the standard debate that roils the siting of most waste facilities, Site 41 has been delayed by a need for an environmental inspector, poor access road conditions, and difficulty obtaining the specified geotextile.

Halting Erosion from Development

0
While many see the US property market eroding, property in development remains a significant threat for erosion. North Carolina's Henderson County is preparing for the construction of nearly 8,000 new homes. Construction runoff is the top source for water pollution in the state. A number of technologies will be needed in order for the Blue Ridge-located development to go forth cleanly.

Lining Whitewater

0
In Charlotte County, North Carolina, a non-profit organization has spearheaded construction of a $38 million hiking, rafting and climbing park. The manmade whitewater course is perhaps the first of its kind and uses a synthetic liner to prevent leakage through and wear against the concrete liner. Learn more here.;

The Never-Ending Story

More major fines have been assessed to developers who ignore the proper installation stormwater and sediment control technologies on construction sites. Five developers in Tennessee were recently fined a combined $4.5 million. These companies need help--not for payment of the fine but for learning the right technologies to avoid them.

China's largest composites production facility is under construction. Among the many materials to be produced in Tiana Group's new facility will be geogrids. The Chinese infrastructure continues to expand at a rapid clip and geosynthetics are being designed into much of it for long-term support. Learn more here.;

A Stormwater Regulation Backlash?

0
Princeton Borough, New Jersey has placed itself at risk of fines for rejecting state-mandated stormwater control regulations. At issue is how the city regulates the many small residential construction projects that occur each year, such as the building of an addition. The city council feels that the state rules are too severe for the average homeowner. Learn more here.;

Ventura and USACE Must Wait

0
Ventura, California would like to construct an artificial reef to rebuild and protect the beach. The design comes from New Zealand's ASR Limited, known for geotextile bag reef constructions. But funding for the project requires the US Congress re-opening the Water Resources Development Act, which would allow the US Army Corp of Engineers (USACE) to execute the work. Learn more here.;

ASA Report on Subcontracting

China and Unchecked Sediment Runoff

0
Erosion control codes grow more strict in the US as cities and states realize the tremendous pollution problem of unchecked sediment entering waterways. But in China, where development is booming, the rapid construction of a road system is producing dangerous sediment runoff into rivers that feed much of Southeast Asia. Solutions are needed.

Pros and Cons of Separating the Supply and Installation of Liners

0
Engineered Linings, Cape Town, South Africa recently asked geosynthetica.net how prevalent was the practice of owners purchasing their own geosynthetic materials and then contracting an installer to install them, as opposed to the installer being requested to both supply and install the materials. To address this concern, Du Toit Viljoen mentioned that Peter Hardie had prepared a brief note to facility owners to indicate why they (EL) felt the single source option should be preferred. We asked if they would send us a copy of the note to publish with the aim of initiating some discussion.

ASTM International Geosynthetics Committee Developing Prefabricated Vertical Drain Test

0
ASTM International Committee D35 on Geosynthetics is currently developing a proposed new standard that covers the test procedure for evaluating the effectiveness of prefabricated vertical drains to enhance the consolidation of soils under specified conditions. The proposed standard, WK13402, Test Method for Large Scale Consolidation Test for Prefabricated Vertical Drains, is under the jurisdiction of Subcommittee D35.03 on Permeability and Filtration. “For geotechnical engineers that are very familiar with sand drains as a means of accelerating consolidation of soft foundation soils, WK13402 will provide a means of evaluating how prefabricated vertical drains perform in relation to a sand drain,” says L. David Suits, a member of the task group developing the standard and executive director, North American Geosynthetics Society. Suits notes that the proposed standard will be most useful to engineers who are designing structures or embankments over soft foundation walls. For further technical information, contact L. David Suits, North American Geosynthetics Society, Albany, N.Y. (phone: 518/869-2917; Nagsdirector@aol.com). Committee D35 will meet June 27-29, 2007, at the June Committee in Norfolk, Va. For membership or meeting information, contact Christine Sierk, manager, Technical Committee Operations, ASTM International (phone: 610/832-9728; csierk@astm.org). Committee D35 is one of 139 ASTM technical standards-writing committees. Established in 1898, ASTM International is one of the largest standards development and delivery systems in the world. ASTM standards are accepted and used in R&D, product testing, quality systems, and commercial transactions around the globe.

Early Detection and Correction

At school construction sites near Philadelphia, crews have discovered site soils are wetter than expected. This has led to a few obvious problems (sinking retaining wall, cracked floor). To head off future problems, the base at one site is being set lower and nonpermeable geosynthetics are being installed. Learn more here.;

A New Jersey developer has received a $763,500 fine for not controlling sediment runoff from a construction site. The developer had previously received 18 warnings. Properly used, silt fencing, turbidity curtains, and other geotextile products can prevent many of the conditions that lead to these hefty fines. Read about the developer's troubles in the Mt. Olive Chronicle (link below) and the Daily Record (cut and paste the following link into your browser http://www.dailyrecord.com/apps/pbcs.dll/article?AID=/20060721/COMMUNITIES34/609210310/1203/NEWS01 ).
