As with Task 004A, the unit subtotal cost for the dozer is listed as$237.79 but in some previous tasks, it
<br /> has been listed as$237.17, or 62 cents less. Because we are unsure which is the correct one,we are not
<br /> calculating this in the change in task costs, but ask that you do so.
<br /> Task 007a Revegetation South Area, Grazing Mix
<br /> This initial seeding has been done,the week of 14-18 October, 2019, and therefore only a small amount
<br /> 20% need be retained in case reseeding is necessary. See photos. Mulching is underway.
<br /> Original amount reduced by 80%to a new amount of$3,451. i
<br /> Task 007b Revegetation South Area, Semi irrigated Mix
<br /> This initial seeding has been done,the week of 14-18 October, 2019, and therefore only a small amount
<br /> (20%) need be retained in case reseeding is necessary. See photos. Mulching is underway.

<br /> p Original amount reduced by 80%to a new amount of$354.
<br /> Summary of tasks with suggested changed costs:

<br /> t;
<br /> 001 1,789 1,235 554 ,
<br /> 002 1,432 1,050 382
<br /> 003 5,355 3,258 2,097
<br /> 004A 22,624 13,575 9,049.,
<br /> 005 7,963 4,777 3,186
<br /> 007a 17,254 13,803 3,451
<br /> 007b 1,768 1,414 354 '.
<br /> Total changed (above tasks only) 1 58,185 39,112 19,073
<br /> The requested reduction for the above tasks would result in a total reduction of Direct Costs from
<br /> $103,535 to $64,423 and Indirect Costs of$12,431 for a total Contract Cost of$76,854. With the
<br /> addition of project management costs of$3,843,the Total Bond Amount would be $80,697.
<br /> If the dozer unit cost is actually$237.17, the lesser amount of the two used in the original estimalle, the
<br /> Total Bond Amount might be a bit less, although the total dozer hours are relatively small.

<br /> We request you review these suggestions and provide feedback and a new estimate. We realize t at
<br /> since we do not have the estimating software the Division uses available to us,we may be using
<br /> calculation methods that provide a different result, and so impact our figures above. i
<br /> Attached are several photos that show the seeding of the South Parcel. As discussed, we are 7wor ing
<br /> with CDPW to address the issue of turkeys swarming the freshly seeded area. Mulching will redu a that
<br /> impact some, of course. Please let us know any questions or additional info you need. t
<br /> Respectfully,
