  • UNIFORM STANDARD SPECIFICATIONS for PUBLIC WORKS CONSTRUCTION
    UNIFORM STANDARD SPECIFICATIONS for PUBLIC WORKS CONSTRUCTION SPONSORED and DISTRIBUTED by the 1998 ARIZONA (Includes revisions through 2010) FOREWORD Publication of these Uniform Standard Specifications and Details for Public Works Construction fulfills the goal of a group of agencies who joined forces in 1966 to produce such a set of documents. Subsequently, in the interest of promoting county-wide acceptance and use of these standards and details, the Maricopa Association of Governments accepted their sponsorship and the responsibility of keeping them current and viable. These specifications and details, representing the best professional thinking of representatives of several Public Works Departments, reviewed and refined by members of the construction industry, were written to fulfill the need for uniform rules governing public works construction performed for Maricopa County and the various cities and public agencies in the county. It further fulfills the need for adequate standards by the smaller communities and agencies who could not afford to promulgate such standards for themselves. A uniform set of specifications and details, updated and embracing the most modern materials and construction techniques will redound to the benefit of the public and the private contracting industry. Uniform specifications and details will eliminate conflicts and confusion, lower construction costs, and encourage more competitive bidding by private contractors. The Uniform Standard Specifications and Details for Public Works Construction will be revised periodically and reprinted to reflect advanced thinking and the changing technology of the construction industry. To this end a Specifications and Details Committee has been established as a permanent organization to continually study and recommend changes to the Specifications and Details.

  • 28 February 2020 Full Year 2019 Results Boart Longyear Limited
    28 February 2020 Full Year 2019 Results Boart Longyear Limited (ASX: BLY) – Boart Longyear, the world’s leading provider of drilling services, an expert in providing valuable orebody knowledge, and a pioneer in innovative drilling equipment and performance tooling, announces results for the full year ended 31 December 2019. All results are referenced in US dollars. KEY METRICS FOR YEAR THROUGH 31 DECEMBER 2019 (Compared to 31 DECEMBER 2018) • REVENUE – $745M – Down $25M - After eliminating impacts of FX, discontinued operations and slow-moving inventory revenue was comparable to 2018 • ADJUSTED EBITDA – $87M - Up $6M (8%) on improved pricing, productivity gains and adoption of AASB 16 Standard • NET PROFIT AFTER TAX – ($45M) – Lower by $1M impacted by Impairments of Intangibles of $9M and additional tax expense of $16M. • NET DEBT - $764M – Increase of $81M from PIK Interest and the adoption of AASB 16 Standard • NET CASH FLOWS FROM OPERATING ACTIVITIES – $35M – Improvement of $31M due to improved EBITDA and initiatives to improve Net Working Capital The Company’s steadfast commitment to safe operations resulted in over 14 million consecutive man-hours with no Lost-Time Injury (LTI), including a company-wide accomplishment of only one LTI through 2019. This safety record demonstrates the commitment to safety by our employees which has resulted in an industry leading performance. Jeff Olsen, Boart Longyear’s CEO commented, “With the support of our global workforce the Company was able to increase its EBITDA and Cash Flow from Operations on lower revenue. Like many in our industry we witnessed organic global demand decline through the second half which we attribute to the several significant mergers and acquisitions within the mining industry, which in turn delayed mineral exploration projects and reduced overall market activity.

  • EXPLORATION Edmund Joseph Longyear
    EXPLORATION Edmund Joseph Longyear Edmund Joseph Longyear founded the company EJ Longyear (which has now become Boart Longyear) in 1890 when he “inherited” an old abandoned diamond drill on the Iron Range in Minnesota. EJ Longyear His company basically invented contract diamond drilling and most of the drills and in-hole tools necessary to accomplish that expensive and necessary task. Many don’t realise that the company was also very involved in contract geological services, contract mining and shaft sinking in the early part of the 20th Century. Longyear’s company’s wireline-retrieved ‘Q’ core- barrel revolutionised the exploration business in the 1960s and is still the standard used in the business today (in only slightly modified form). This innovation so reduced the cost of drilling that it could be suggested that many deposits were able to be found and delineated with the funds saved versus the conventional methods of core sample retrieval. EJ Longyear’s historic first diamond drill site on the famed Mesabi Iron Range of Minnesota was the beginning of a new era in iron and mineral exploration, and, under his technical direction, the Mesabi Iron Range became one of the largest regional areas of diamond drilling the world has ever seen. In 1888 Longyear was a member of the first graduating class of Michigan College of Mines in Houghton. Later that year, he directed exploration and diamond drilling for his cousin, JM Longyear, on the eastern end of the Menomonee Range in Michigan. This was his first connection with diamond drilling. In the meantime, reports were coming in from northern Minnesota of the possible existence of a new iron range, and, on May 22, 1890, EJ Longyear arrived at the Mesabi Range.
