REVISED - Price and Proposal for Fxtra \8"ork Associated with Additional
Clearing
Dear Mr Rosser
Sharpe Brothers offers the following revised unit prices and proposal for the extra work
associated with the additional clearing in the Runway 23R RPZ based on our meeting of May 21,
2008 to discuss the original prices and proposal.
This work is anticipated to take 3-4 weeks depending on weather conditions and/or
Engineer/Agency directives that may impact production.
The following conditions apply to this proposal:
I If the conditions of access to and within the areas to be cleared is altered from the agreed to
terms (change order) on which this price is based before or during work, these prices will no
longer be valid. Prices are based on maximum of 120' drag lengths from allowable mechanized
access points/areas. A sufficient number of access points/areas must be allowed by the Owner
and Agencies so that this maximum drag length will be capable ranging all areas to be cleared.

clearly marked with orange fence or other easily recognizable markings; (b) all trees to be
removed within the CE will be marked, (c) all areas where mechanized access through the CE is
permissible will be marked/identified, (d) the MALSR boundary will be marked so that it can be
utilized as a means of mechanized access.
4. All erosion control devices will be installed and functioning properly prior to work beginning.
S Non-mechanized/hand silt removal not included.

ramps.
10. Owner and Agencies accept that damage to trees that are to remain and other vegetated areas
within the CE is unavoidable. The Owner and Agencies further accept that rutting and other
damage to all areas within the CE is unavoidable regardless of whether clearing is by
mechanized means or via cutting and dragging.
11. Additional mobilization costs will occur if the Engineer or other Agency issue directives that
halt work in excess of 4 hours.
12. Owner understands that work will not begin until such time as RPCA is paved.

identified in figure 3 of May 8, 2008 information provided to Sharpe Brothers.

time guidance and directives regarding access, boundaries and tree removal.
21 The Engineer will conduct a pre-construction meeting on-site pnor to the start of work with
all involved parties in order to review conditions of access, boundaries, and address any
