Keith,
In the first change request I sent to you, I based my quantities on using 2000cy of onsite dirt and importing the
remainder. So the 3770cy number was based on both bank yards for the onsite material and truck yards for the
imported material. When I priced this last change request I confirmed with my foreman that he believed he
had all of this material onsite now so my comparison was based on the difference of volume between the first
revised plan (3311cy of fill) and the last revised plan (550cy of fill). I can provide the takeoffs if you like, I was
just mentioning this note as a matter of facts, probably should have defined how I recalculated my quantities
as well.
In regards to your opinion of using pay item 107 I am going to disagree as this bid price was based on making
the fills from the existing topo to the original proposed grades as a mass excavation process over a majority of
the site with fill depths of 1’ to 3’. The plan changes being made here are based on grade changes that require
fills of .05’ to .90’ with an average depth of .532’. I do not believe the pay item 107 reflects the same scope of
work here as this is smaller fills concentrated in a smaller area and on 44 lots. My production rates are much
lower than they were for the mass grading and thus warrants the additional costs.
In regards to the change I also see you have made in your change order on the lot grading. I am not sure if this
a typo or you intentionally made these changes but they have been reduced as my total for the rough grading
and fine grading is $439.00/each not $378.20/each. If this was an intentional change then I again am going to
have to disagree with you on the same basis as the fill item above. These lots are very small (95x32) and
(96x30) and they are “zero” lot lines with 3’ drainage easements. A typical subdivision lot is one and a half to
twice the width with and a tad bit longer with a 10’ drainage easement. The lot grading production is slowed
down by the smaller lot size and the drainage easement at 3’ is going to be very difficult to grade. The swales
are one foot off the edge of the pad and one foot lower than the pad, this will require slower production and
hand grading to establish. I cannot agree to this price change.
Also this added work is going to add time to our schedule in the amount of ten days that will need to be added
should we be able to agree on a dollar amount for this work. I will also note that I did not request additional
cost in the last change order request for the grade staking that should have been as these lots will have to be
restaked for these new grades. The cost for the grade staking will add another 40 hours for rough staking and
20 hours for final staking at $125.00/hr for an additional $7,500.00.
I believe these prices are more than fair for the added scope of work if you take into consideration the facts I
have identified above. If you want to meet about this with the developer we can but I do not see any reasoning
that would be convincing enough to lower my unit pricing as provided. I think everyone should consider the
facts I have provided before making any further judgment on my pricing.

Marty,
Comparing the two change order letters below, I see only a 91CY difference in your estimated quantity of on-
site material to be used in this effort between the 1/13 letter and the 2/15 letter.
It also seems to me that pay item 107 Embankment (on site) should apply to the 3,861CY of material to be
moved from one location on site to another. Using that item, and the contract unit price of $3.46, it seems that
item 1 in your request should be reduced to $13,359.06.
We understand that time is of the essence in reaching an agreement here, so I have taken the liberty of
preparing a change order document reflecting the above change. I have also consolidated the grading to one
line item, and reduced the cost to an amount that is agreeable to the city and the developer.
If you are in agreement with this proposed change order, please sign and return three copies. If you wish to
discuss this change further, I would be happy to facilitate a meeting between JRJ, city staff, and the developer.
Thanks,
Keith
