Commercial Building Floor Plans | Project Summary 9

A few weeks ago an architecture firm, who I’ve done business with in the past, contacted me and requested a cost proposal to field verify the accuracy of two of their AutoCAD files that contained commercial building floor plans. The plans were of an existing commercial building located in the heart of the Financial District of New York City.

The architecture firm was hired to design new floor plan layouts of these floors, for the future tenant of these spaces. The files were provided by the building owner, via their real estate broker.

The architecture firm’s scope of work was to remodel the two floors that were contained in the AutoCAD files, for their client who was to be the future tenant of the floors. To accomplish this the architecture firm would need AutoCAD files that accurately depicted the floors. They called me and requested that I create these files for them.

The architecture firm and I hammered out the details of my cost proposal, including the exact scope of work, and then I began my task of creating accurate commercial building floor plans.

Project Summary
Item Description
Type and Location: A 63 story commercial building located on Wall Street in the borough of Manhattan.
Client: Architecture Firm
Summary of Scope of Work: For the 18th and 19th floors: Field verify overall floor plate dimensions, the size and location of all building columns, and the size and location of the core, which includes: elevator banks, bathrooms, stairs, mechanical rooms, and any miscellaneous rooms. Additionally, field verify critical dimensions at stairwells and bathrooms, for egress requirements and ADA compliance.
Area: 18th Floor = 26,620 sq.ft. and 19th Floor = 24,000 sq.ft.
Was the space occupied with tenants?: No, the floors were vacant.
Access Restrictions: I gained access onto the floors through the building owner’s real estate agent. However, some mechanical rooms were locked, so I was unable to access them.
Field Setup and Breakdown Time: This time is lumped into my field time.
Field Measuring Time: Total for 18th and 19th floors = 26.25 hours.
Total Travel Time: 9.00 hours (three trips)
CAD Drafting Time: Total for 18th and 19th floors = 34.25 hours.
Misc. Time: 1.50 hours of project coordination.
Crew Size: 1 man
Equipment Used: Hand held laser, tape measure, camera (optional), pens, pencils, eraser, paper and foam board.
Comments: The way I decided to do the field verification work was to print out the two floor plans on 24×36 paper, and mark whatever verification dimensions that I could on these sheets. Where the floor plans deviated allot from the printouts I made sketches on separate sheets of paper.

It turned out that the field conditions differed a fair amount from the AutoCAD files. Therefore, instead of modifying the existing files, I redrafted everything.

Throughout the project I kept the project manager abreast of my progress and findings, so that we were always on the same page.
