United States General Accounting Office GAO Washington, D.C. 20548 National Security and International Affairs Division B-229358 September 20,1988 The Honorable John Dingell Chairman, Subcommittee on Oversight and Investigations Committee on Energy and Commerce House of Representatives Dear Mr. Chairman: The Army, having decided that its fleet of construction vehicles was becoming too costly to keep in repair, directed European units in 1985 to dispose of commercially available combat engineer construction vehi- cles. The Army purchased 850 replacement vehicles for Europe costing about $79 million. The purchase was part of a worldwide replacement program totaling about $470 million through fiscal year 1987. As you requested, we reviewed the Army’s replacement of construction vehicles in Europe. Our objective was to determine the basis for replac- ing these vehicles. We agree with the Army’s goal to replace worn-out vehicles with stan- dardized ones, but question its decision to dispose of usable vehicles without showing that it was cost-effective to do so. Army officials stated that old construction vehicles were difficult to support and that high repair costs made replacing the entire fleet -regardless of condi- tion-cost-effective. We found no analyses to support the Army’s position.

The operator was employed by a contractor that does site development, single family home construction, and commercial construction work. He had previously owned a construction contracting business and had 48 years of experience operating bulldozers and other heavy construction equipment. On the day of the fatal incident, the operator was supervising a crew. The crew was working at a job site zoned for commercial development, where structural fill was being brought in and dumped and then leveled and compacted. As dump trucks hauled fill onto the site, the operator was using a Caterpillar D4H Series II bulldozer to level the fill and was also directing the drivers as to where they should deposit their loads. At 7:40 AM, the operator exited the bulldozer on its right side to speak with a truck driver about where the driver should deposit his load of fill. When he did this, he left the bulldozer running and did not set the parking brake.

  • United Nations Peacekeeping Missions Military Engineers Manual
    United Nations Peacekeeping Missions Military Engineer Unit Manual September 2015 0 Preface We are delighted to introduce the United Nations Peacekeeping Missions Military Unit Manual on Engineers—an essential guide for commanders and staff deployed in peacekeeping operations, and an important reference for Member States and the staff at United Nations Headquarters. For several decades, United Nations peacekeeping has evolved significantly in its complexity. The spectrum of multi-dimensional UN peacekeeping includes challenging tasks such as helping to restore state authority, protecting civilians and disarming, demobilizing and reintegrating ex-combatants. In today’s context, peacekeeping Missions are deploying into environments where they can expect to confront asymmetric threats from armed groups over large swaths of territory. Consequently, the capabilities required for successful peacekeeping Missions demand ever-greater improvement. UN peacekeeping operations are rarely limited to one type of activity. While deployed in the context of a political framework supporting a peace agreement, or in the context of creating the conditions for a return to stability, peacekeeping Missions may require military units to perform challenging tasks involving the judicious use of force, particularly in situations where the host state is unable to provide security and maintain public order. To meet these complex peacekeeping challenges, military components often play a pivotal role in providing and maintaining a secure environment. Under these circumstances, the deployment of UN Military Engineers can contribute decisively towards successful achievement of the Mission’s goals by providing the physical wherewithal to exist, sustain and fulfill its mandate. As the UN continues its efforts to broaden the base of Troop Contributing Countries, and in order to ensure the effective interoperability of all UN Military Engineer Units, there is a need to formalize capability standards.

  • Noise Level Analysis of a Bulldozer Used in Constructing a Forest Road in Mediterranean Region of Turkey
    African Journal of Agricultural Research Vol. 5(19), pp. 2624-2628, 4 October, 2010 Available online at http://www.academicjournals.org/AJAR ISSN 1991-637X ©2010 Academic Journals Full Length Research Paper Noise level analysis of a bulldozer used in constructing a forest road in Mediterranean region of Turkey Hasan Serin* and Abdullah E. Akay Faculty of Forestry, Kahramanmara Sütçü mam University, 46060 Kahramanmaras, Turkey. Accepted 20 April, 2010 Heavy machinery utilized in forest operations, as one of the working environments with intensive noise disturbance, result detrimental effects on the workers’ health. Particularly, high level noise generated from the road construction machines causes physiologic and psychological health problems on the operators. Among these problems, one of the most important occupational problems is hearing impairment or permanent hearing loss. In this study, the average and peak noise levels generated by a CAT D7G model bulldozer during two working stages (that is, unloaded running stage and road construction stage) of a road construction activity were measured from the operator cabin. The results indicated that the average noise levels for unloaded running stage and road construction stage were 73.87 and 84.11 dBA, respectively. The peak noise levels were measured as 95.90 and 113.40 dBA for unloaded running stage and road construction stage, respectively. Thus, it was found that the mean values of the average noise levels in both working stages were less than the warning limit of 85 dBA. The results also indicated that all of the peak noise levels were over the hazard limit of 90 dBA for both stages.

  • Development of Pc210lci-10/Pc200i-10 Machine Control Hydraulic Excavator
    Technical Paper Development of PC210LCi-10/PC200i-10 Machine Control Hydraulic Excavator Yuki Shimano Yoshiki Kami Kenichirou Shimokaze In recent years, the efficient construction work thanks to the computerized construction utilizing the ICT technology has been expanded in the market, which contains shortening of a construction period by abolishing the finishing stake which was necessary in the conventional construction work, improvement of execution accuracy, and execution progress management. From this trend, there are growing needs for construction machinery responding to it. When it comes to hydraulic excavators, machines installed with Machine Guidance (MG) have been commercialized including after-market products. However, finishing grading was somewhat dependent on skills of operators monitoring the display. Accordingly, we have developed the machine-controlled hydraulic excavator highly improved in construction efficiency, which enables machine control in a series of operations from rough digging to grading, thanks to the combination of the hydraulic control technology from Komatsu unique components and the GNSS surveying technology. This excavator has released on the computerized-construction-advanced markets of Japan, U.S. and Europe ahead of other competitors.
