2002 Feasibility Study:
Report Operations Improve Crawl Space Working Conditions At the feasibility study meetings, maintenance staff reported that the crawl spaces are difficult to work in. The suggested improvements were:
At the present time the crawl space contains the following piping:
The following photo is a view into the crawl space from the top of the access ladder.
The most dangerous pipe components in the crawl space are the 180° very hot water supply and returns. These are also the easiest to eliminate. This water only supplies the bedpan flusher in the soiled utility room and a mixing valve to make 125° hot water for nurse utility areas. In more modern construction, the need for 180° water has been eliminated. The bedpan flusher has been replaced with a flushable clinical sink with only domestic hot and cold water supplies. All of the other nursing service plumbing fixtures are supplied only with domestic hot and cold water supplies. Should there be a need for water temperatures above 110° , a local electric booster could be installed. With the replacement of the skilled nursing wings, this problem will be automatically eliminated. Should the new construction not take place, these changes could be made in their present locations. Presently, there are two accesses to the crawl spaces: a 2’ X 2’ floor hatch in the middle of a resident corridor and an access door at the top of a vertical ladder. A few feet beyond the floor hatch, the crawl space ends at an exterior wall. This exterior wall could be removed and the crawl space extended to have an exterior access. The cost of constructing the three exterior accesses would probably not exceed $20,000.00. Increasing the height of the crawl space is a more costly proposition, because it would be very time consuming. Furthermore, the plans did not indicate the depth of the crawl space footers. Thus, we would assume that they are not deeper than 4 or 5 feet, except where the original grade elevation was more than 4 feet below finished floor. A vacuum truck of the type used to clean out storm sewer manholes could be utilized, with some modification, to vacuum out the finer excavated materials. Stones and rocks would have to be hauled out by hand. There is also room for one person only, probably with an electric hammer with a spade tip, to work at the end of the crawl space where the excavation is taking place. Assuming that the excavation would start at the newly constructed exterior access, only one person could work in the crawl space for the first 35-40 feet, until the excavation was past the "T" in the crawl space. Thereafter, two people could do excavation work in different sections of the crawl space. However, they would most likely have to take turns in having their excavated materials vacuumed out. In order to preserve the structural integrity of the building, no excavation should be performed below the mid-point of the footer. We have no way to accurately estimate the cost of such hand work, but it could very likely take several months to do all three wings. Thus, we would suggest that this work be performed by "forced account" rather than by an outside contractor. If the entire wings are being renovated, as in the case of the proposed Adult Home, then the three domestic water lines could be relocated in the corridor ceilings, which would leave only the sanitary sewer lines remaining in the crawl spaces.
