As we stated last week, we are going to be taking the ideas developed in this column over the last couple of years and developing them into design practices. This is how it will work. We will provide the basic narrative here for one design practice each week. We will keep it open for comments for one month. After that, we will finish it in formal form and offer it for sale at a modest price. Here is where you come in. If you make a substantive contribution to a standard, the organization for which you work will be granted a pro bono license to use that standard with its current issue number for as long as you like.
Here is the first: Foundation Dependent Site Selection Design Practice. (LGM 2013.010.01 when issued)
Reference It is generally agreed that foundations and structure represent about 75% of the weight of an installed pulp and paper industrial facility. Parameters for soils conditions are often overlooked when performing site selection activities. Objective Elevate foundation conditions as a consideration in site selection. Considerations Site selection often involves parameters such as logistics, utility access, skilled workforce availability and so forth. Soils conditions, and the necessary foundation requirements are usually given only a passing consideration. However, cases have been documented where foundation installed costs have reached as high as 14% of total installed costs. This is due to soils and hidden conditions. Methodology Priorities in site selection should, of course, include logistics, proximity to utilities and workforce availability. However, these matters should be considered on a macro basis first, say within a radius of 60 miles (100 km). Once these priority matters are narrowed as described above, several likely sites, taking into account primarily highways, rail and utilities should be identified. Finally, soils conditions should be examined in some detail and an estimate made as to the cost of foundations within the several sites. Negotiations Once the above matters have been thoroughly investigated, final site negotiations can begin. The negotiators now have a new tool, new information to use: soils conditions. Final site price should take into account soils conditions and reflect additional expenses, if any. So, give us your comments by 6 Feb 13, please!
And we will be doing something else with the weekly ideas--we will be discussing many of them in a round table discussion at the LGMI Annual Conference January 27 - 29, 2013 here in Atlanta. You can attend in person for free or online for a nominal costs. You will need to sign up soon as openings are limited. Sign up here.
As always, your comments will be appreciated.
