As-Built Drawing / Surveying Services

As-Built Drawings / Surveying

It is common to run into roadblocks during construction. The process is very complex, which is why problem solving is an important skill to obtain in this industry. Modifications are bound to be made as the project moves along and the final result may not resonate with the initial plans. This is why as-built drawings are encouraged, for they depict a rendering of the building in its final form. As-built drawings are essential to the proper maintenances and servicing of the MEP equipment and systems. They provide a clear record of what equipment has been installed and where valves, smoke / fire dampers and access panels have been installed etc.

Coordination Drawings Services

Coordination Drawings

The ultimate purpose of a coordination drawing is to avoid and eliminate any physical coordination conflicts that may arise in the layout. For instance, it assures that there is a sufficient amount of space available for the equipment intended to be used. This is often done prior to the start of a buildings construction process in order to create a more efficient way of working for everybody involved. Buildings with complex mechanical, electrical and plumbing requirements run a greater risk of physical interferences which is why coordination drawings are not only a great help but necessary for the successful completion of any project of any size.

Shop Drawings Services

The production of installation and coordination shop drawings is a crucial and rather essential component in the process of construction. It is a highly detailed and informative drawing that depicts all the technicalities listed in particular construction documents but in drawn form. The overall intention of a shop drawing is to logistically plan out and exemplify both the fabrication and installation of the required and needed items to the manufacturer’s production crew or contractor’s installation crews. Sleeve / penetration drawings will also be provided for approval by the A/E of Record.
