Inspection of Fireproofing works

Inspection of Fireproofing works:-
Growing concern over fire safety in public buildings has greatly increased the demand for fire-resistive materials in buildings. Stricter building codes have boosted industry standards, creating a specialized and high profile market for these materials and the contractors who apply them. However, fire-resistive materials must be applied properly to protect the building structure. Inspection is one means of evaluating that fireproofing is applied in accordance with approved project plans and specifications, and with the intended materials.
One of the key elements of any project is to provide knowledgeable technicians capable of performing the required testing services. Inspection technicians be trained to perform testing and inspection on various types of fire-resistive materials, including in tumescent paint. Also, we should consider the importance of maintaining the construction schedule and providing personnel with the necessary experience, capabilities, and equipment.
Special inspection of fireproofing is often required by the local building code or by the owner through the architect or the engineer. Basic responsibilities of any inspectors are, to understand the project specifications and local standard codes make sure the project is constructed in accordance with the contract documents. Inspectors at reputed international organizations shall have extensive experience in testing and inspecting various fireproofing materials, including sprayed fire-resistive materials (SFRM) and thin-film in tumescent fire-resistive materials (TFIFRM). Through years of education and experience, inspectors will gain a vast knowledge of the codes and specifications governed by the Uniform Building Code (UBC), International Building Code (IBC), the American Society for Testing and Materials (ASTM), the Underwriters Laboratories Inc. (UL), and the Association of the Wall and Ceiling Industries (AWCI).

Inspection of Fireproof Lathing and Plastering Work
Lathing. Before the lathing is begun, the inspector should see that the furring and grounds are properly placed and are plumb and square; also, that the angles of chimneys and other projections are right angles. If the lathing is wood, he should see that the laths are free from bark and loose knots, and that they are put on with proper spacing, well nailed, with no springy ends, and end joints broken at least every 18 inches. Over door and window openings, the laths should extend to the next stud on either side of the frame. As far as possible, the lathing should run the same way, as cracks are likely to appear in the plastering at the places where the direction of the laths is changed. The junction of brick and wooden walls, as well as lintels and unfired timbers, should be covered with metal lath, as before mentioned.
Plastering. If lime plaster is to be used, the inspector should see that the lime is fresh and without unburned lumps, and should allow none to be used that has begun to slake. The sand used should be sharp and free from earthy matter. The hair should not be added until the lime has become thoroughly slaked and cooled, and the mortar should be made at least a week before use. It is well to become acquainted with the appearance of good mortar, so as to be able to judge its quality.
Before beginning to plaster, the openings in the building should be closed up with boards or canvas. In winter, a building in which plastering is to be done must be heated; lime mortar, especially, is rendered worthless if frozen and thawed; hard plasters, also, should not be permitted to freeze. The inspector should see that the first coat is well clinched between the laths, and is thoroughly dry before the second coat is put on. If the scratch coat is to be laid on brick, the walls should be well wetted before applying the mortar. Special care should be taken with the brown coat, as the appearance of the finished work depends to a great extent upon good workmanship in applying this coat. Its surfaces should be plane, with straight and square angles and a level ceiling. If hard plasters are used, the directions furnished by the makers should be carefully followed, in regard to mixing sand, etc. (if not obtained already mixed). Plaster that has partially set before use should be rejected. 2-21
Annual Fire Inspection.
Annual inspections by the fire department are performed to assess and mitigate potential fire- and life-safety hazards in buildings. Most fire departments provide you with a written report of any corrections that are necessary. These inspections vary in type and frequency, depending on the jurisdiction, city, and state. How the fire inspectors perform these inspections also varies dramatically from area to area.
About Fire Inspector
Training and experience of the inspector also impacts the inspection process, and can negatively or positively influence your inspection. Most inspectors have a boss, so feel free to ask for a second opinion if you're not comfortable with your fire inspector. Different types of occupancies may have different requirements. The processes or products used in a building may also require different systems or protection. If the building is a special use, such as a high-rise, there are additional code requirements.
Finishing the Inspection Process
Stress your concerns about making the building as safe as possible by working positively with the fire department to achieve compliance. Ask questions and make sure you fully understand all issues. If there are corrections required, identify who is responsible for making these. If the building owner is different than the business owner, then responsibility must be determined for each item. In many cases, the building owner and business owner are responsible, by lease agreement, for different items. It needs to be identified for the fire inspector who is responsible, and who will communicate these items to the responsible party, if not present.
If there are costly items requiring attention, discuss alternatives and compliance timeframes with the inspector. Most fire inspectors are willing to negotiate a longer time period since the inspector is most interested in gaining compliance and making your building safer without causing you financial difficulties. Not all compliance items cost a great deal of money or require great effort. Many can be operational issues and are easily corrected.
