Good Afternoon,

Having just purchased an e-copy of the BOMA 'Standard Method for Measuring Floor Space in Office Buildings', we would like to request clarification on the definition used for 'Major Vertical Penetration' please, as we understand that to calculate Floor Rentable Area it is usual to deduct Major Vertical Pentrations from the Gross Measured Area on a floor by floor basis.

Please allow me to outline our situation: We will be renting all floors of an 18-storey office block, which is currently under contruction in Lagos, Nigeria, and as such shall be the sole tenant.

We would like clarification on whether or not vertical penetrations such as stairs, elevators, shafts, flues, pipe shafts, vertical ducts etc should be included or excluded in the Major Vertical Penetration calculations in this situation ie as sole tenant.

We do not intend to add any 'private vertical penetrations' to those already in the general building design, however, as we will be the sole tenant, are the general elevators and stairs considered to be of private use and therefore to be excluded in the calculations for Major Vertical Penetrations, or not?

Hoping to hear back from you as soon as possible.

Many Thanks for your time.

Regards
