Construction Equipment Cost Analysis
- An economic evaluation technique that involves the systematic collection, categorization, and analysis of program costs.
- breaking down the costs of some operation and reporting on each factor separately
- (Cost Analyses) The review and evaluation of the separate cost elements and proposed profit of a contractor's cost or pricing data. Cost analysis always includes price analysis.
A Statistical Analysis Of Construction Equipment Repair Costs Using Field Data
This is a AIR FORCE INST OF TECH WRIGHT-PATTERSONAFB OH report procured by the Pentagon and made availab
le for public release. It has been reproduced in the best form availab
le to the Pentagon. It is not spiral-bound, but rather assembled with Velobinding in a soft, white linen cover. The Storming Media report number is A578643. The abstract provided by the Pentagon follows: The management of heavy construction
equipment is a difficult task. Equipment managers are often called upon to make complex economic decisions involving the machines in their charge. These decisions include those concerning acquisitions, maintenance, repairs, rebuilds, replacements, and retirements. The equipment manager must also be able to forecast internal rental rates for their machinery. Repair and maintenance expenditures can have significant impacts on these economic decisions and forecasts. The purpose of this research was to identify a regression model that can adequately represent repair costs in terms of machine age in cumulative hours of use. The study was conducted using field data on 270 heavy construction machines from four different companies. Nineteen different linear and transformed non-linear models were evaluated. A second- order polynomial expression was selected as the best. It was demonstrated how this expression could be incorporated in the Cumulative Cost Model developed by Vorster where it can be used to identify optimum economic decisions. It was also demonstrated how equipment managers could form their own regression equations using standard spreadsheet and database software.
eight hours in the office sunday
trial prep. despite what law & order would have you believe, a full trial is pretty rare. we have one starting tomorrow. the lead attorneys have put in far more than 8 hours a day for nearly a week. us junior folks kicked in some time today. lots of printing and organizing and, obviously, lab
don't get me wrong. I loved law school. it's this lawyer thing that's not actually so great as I'd hoped. I find this sentiment to be fairly prevalent. everyone in my office teases the paralegals who plan on going.
at this point--with the cost of a legal education balanced against how much money you can really make as a young lawyer--I don't think it's worth it. the amount of money I pay to debt every month would be enough for a really nice apartment in an up and coming neighborhood, and I wouldn't be 30 and living with my mother. that sucks. but I have a highly-respected degree from a highly-respected school. and I'll be paying for that for decades.

This study describes the impact of the use of mechanised equipment on physical load and workers' health among road workers and floor layers by comparing the traditional manual work method with frequently occurring scenarios of use of this new equipment. Continuous direct measurements of postures were linked to real-time observations of tasks and external forces applied during manual materials handling. A self-administered questionnaire on musculoskeletal complaints was used. The introduction of a hydraulic clamp or vacuum lift to assist roadmakers while laying a brick-paved road reduced the team's work time in a kneeling/squatting position with 43-52% and frequency of lifting loads of 5-15kg and above 15kg with 46-59% and 84-88%, respectively. The introduction of a mixing machine with a pump system during pouring of sand-cement floors reduced the frequency of lifting loads with 66% for 5-15kg and 15% for over 15kg, but had no discernable effect on awkward back postures. The use of a silo/truck with automated pump system also reduced the frequency of lifting with 32% and 38%, respectively, but increased the duration in awkward back postures with 13%, primarily due to the hodman partly working as floor layer. Floor layers and hodmen using the mechanical equipment reported a lower prevalence of low back pain in the past 6 months and also less associated sick leave. The introduction of new mechanised equipment resulted in changes in physical load per task within jobs, changes in task distribution within jobs, and changes in work organisation and jobs within a team. The judgement of experts on the impact of new devices on physical load should be corroborated in field studies on the average exposure to physical load per work day and per team. Relevance to industry: The study demonstrated the preference of a scenario approach in evaluating the impact of interventions on physical load above the classical analysis of the most strenuous task.
