\"Deteriorating<\/a>

Deteriorating pipes found right below the surface of the terraces at Village House.<\/p><\/div>\n

One of RAND's recent projects was supposed to be a routine roofing replacement job, until contractors discovered sand where there should have been concrete.<\/p>\n

Village House, a 75-unit, 14-story Greenwich Village condominium located at 60 West 13th street and built in 1967, had a history of leaks around its two wraparound terrace spaces on the 12th<\/sup> floor and penthouse levels. According to longtime board president\u00a0Carol Butler, the terrace areas had deteriorated and water was leaking into the units.<\/p>\n

The board contacted RAND to perform an evaluation. After an initial probe, it appeared to be nothing out of the ordinary. A plan was made to put a new waterproofing system under the terrace setbacks where the old system was. The condominium hired Avarga Contractors to perform the construction work.<\/p>\n

\"Roof<\/a>

Village House: Condominium roof replacement project with a big surprise.<\/p><\/div>\n

However, once Avarga workers began demolition, we encountered a surprise. The concrete under the terrace flooring on top of the setback looked very sandy. We realized that the sandy concrete was only a very thin layer.\u00a0What was initially thought to be the concrete slab was a very thin layer of crumbling, sandy concrete, and directly beneath that was a one-foot deep layer of sand and gravel.<\/p>\n

Upon further inspection, we discovered deteriorating pipes embedded in the sand and gravel that turned out to be plumbing lines that fed the heating and air-conditioning system. \"They were almost 50-year-old pipes,\" Butler said, \"and they seemed to be quite deteriorated.\u201d<\/p>\n

After taking into account the presence of the plumbing, we developed a new sensible and cost-effective roofing replacement concept. Another contractor,\u00a0RVM Plumbing<\/a>, was brought in to remove and replace the piping and add more insulation materials around the new pipes. Once the plumbing was replaced, pavers and drains were installed.<\/p>\n

Also closely involved in this project was RAND project associate\u00a0Yessica Marinez\u00a0and manager\u00a0Jeffrey Lamb\u00a0of\u00a0J&C Lamb Management<\/a>. Far from routine, the challenging project turned out to be successful in a very interesting way.<\/p>\n
