FACTORES DE SEGURIDAD Agregar factores de seguridad es una buena práctica ingenieril. El factor de seguridad mínimo sugerido es de 1,75. El lineamiento es que cualquier plano de un cimiento incluya una declaración del factor de seguridad usado. Comúnmente se incluye dentro de la sección de NOTAS. 7. DESVIACIÓN O FLECHA EN LAS SUPERFICIES QUE SOPORTAN LA CARGA Es deseable definir una flecha máxima en la superficie que soporta la carga. Por ejemplo, un desvío máximo de 1/16” tanto en las superficies horizontales como en las verticales es obtenible por la mayoría de los contratistas calificados. 8. NIVELADO Y RELLENADO Es preferible rellenar con lechada de alta resistencia y almohadillas fabreeka a utilizar cuñas de relleno, ya que tienen una mayor capacidad de tolerar cargas que las cuñas. 9. GESTIÓN DEL CONTRATISTA Se recomienda que ya sea el fabricante de la máquina o bien el dueño de la misma mantengan un diálogo fluido con el contratista encargado de los cimientos. Hay muchos niveles de información requeridos entre el contratista y quien conoce el equipamiento, una comunicación clara y abierta ayudará a eliminar errores en diseño y ejecución. 4. Dynamic load designations The dynamic load for each pad should be shown in any of the methods below: 6. Safety factors Adding a safety factors is good engineering practice. The suggested minimum safety factor is 1.75x. The guideline suggestion is that any foundation plan included a statement of the safety factor used throughout the drawing. This is commonly listed in a NOTES section. 7. Deflection on load bearing surfaces It is desirable to define a maximum deflection of the load bearing surface. For example, a maximum deflection of 1/16” on both vertical and horizontal surfaces should be obtainable by most qualified foundation contractors. 8. Shimming and Leveling High strength grout and fabreeka pads are preferred to shims because they provide much better load bearing capabilities than shims. 9. Contractor management It is highly suggested that either the machine OEM or the responsible owner maintain open lines of communication with the foundation contractor. There is a varying degree of information required between foundation contractors and being clear between owner and contractor will help to eliminate errors in design and execution.

Drawing methods When drawing a diagram such as the one below, it is important to pick a point somewhere on the diagram, label it, and list the moments about that point. 5. MÉTODOS DE DIBUJO Al dibujar un diagrama como el de abajo, es importante tomar un punto en algún lugar del diagrama, etiquetarlo y enumerar los momentos sobre ese punto. 4.
