Repair and renovation

Reduction of the downtime of the structure (hence minimizing productivity losses) and shutdown for repair and renovation and advancement of the time when the structure can be put to use. 

Phase II was the Worker Characterization and Blood Lead Study, which from the title had to do with the PbB levels of renovation and repair workers, while Phase III of the field data gathering evaluated children s PbB levels associated with repairs and renovations in units, the Wisconsin Childhood Blood Lead Study. The final Phase IV segment concerned blood lead data gathering in workers doing repairs and renovations in old, historic homes. In the Dust Study, 12 interior and 12 exterior renovation activities were carried out in vacant units in Ohio. 

The factors responsible for creating the need for repair and renovation can be sub-divided into ... 

As structures made of concrete and allied materials are involved in approximately half of the repair and renovation work, it is important to understand and evaluate the performance of the materials to be used to make good damaged/eroded concrete,and their composite behaviour with the parent structures. While there are many cases where replacement of material in depth is required these are likely to be individual rather than general cases. However, a high proportion of repairs involve the application of surface layers or patches varying in thickness from a few mm to 50 or 100 mm. 

Two materials being widely used for the repair and renovation of damaged concrete are Polymer Concretes (PCs) and Polymer Modified Cement Concretes (PMCCs). These materials are very different in both composition and behaviour. PCs are highly filled polymers (e.g.epoxide resins) and contain no hydraulic cement-water phase. PMCCs on the other hand contain up to about 20% of latex (e.g. Styrene/Butadiene resin ... 

There are two primary TSCA lead programs, the Renovation, Repair, and Painting Rule and the Disclosure Rule. Both were authorized by The Residential Lead-Based Paint Hazard Reduction Act of 1992, codified as... 

The Renovation, Repair, and Painting Rule is in the regulations under the title Residential Property Renovation, and all of the TSCA lead regulations are in Part 745 of 40 C.F.R, which is entitled Lead-Based Paint Poisoning Prevention In Certain Residential Structures. These titles are misleading because the rule covers many nonresidential structures. 

There are several exceptions to the Renovation, Repair, and Painting Rule. 

The Renovation, Repair, and Painting Rule requires renovators to create certifications and keep records that demonstrate compliance with the each detail of the renovation rules for three years, or longer if required by another law7 In practice it is important to retain compliance documents for longer, and the exact length of time depends on the state in which the renovator operates. In most jurisdictions the statute of limitations for a tort action brought by a person who was a child at the time of an injury can be extended beyond the time that would have been allowed for an adult to bring a tort action.In any event records should be maintained for the five years of the TSCA statute of limitations. ... 

Most states have their own lead programs which have been authorized by the EPA and supplant the lead-based paint activities rule in subpart L. ° States and tribes may seek authorization under the Renovation, Repair, and Painting Rule in addition to the lead-based paint activities rule of Subpart L. Section 404 of TSCA ° requires state programs to be at least as protective as the TSCA program before the EPA can authorize them. In those jurisdictions where the state or tribal program has not been authorized by EPA, both the federal and state or tribal programs will be in effect. States and Tribes may become authorized by the EPA to administer and enforce the renovation... 

States and Tribes with authorized programs enforce their own programs. EPA has stated that it reserves the right to enforce the Renovation, Repair, and Painting Rule in states that have their own authorized programs. 

The EPA has not developed an enforcement response policy specifically for the Renovation, Repair, and Painting Rule or the Pre-Renovation Education Rule. In In the Matter of Millennium Quests, Inc., the Regional Judicial Hearing Officer relied on the enforcement response policy for PCBs in the absence of an enforcement response policy that was directly applicable to the Pre-Renovation Education Rule.

If the dry paint film is to be a useful one, it must stick to the surface beneath, be hard enough and flexible enough for the purpose for which it is used and must retain most of its protective and decorative properties for a long period. The paint should be capable of repair or renovation. Let us now take these requirements separately and see how they are achieved.
