Dear Bill:
The following is an explanation of the costs and credits being
submittcd by the gencral contractor. Thcy are listed in the same order
as they appear on the contractor's Change Order Request.
1. Upon exposure of the cxisting wide flange beam, unforseen
bolts and web stiffeners were discovered. Portions of the
existing web stiffencrs had to be removed and replaced.
Holes had to be dri lled in the new steel bars to clear the
existing bolts and thus facilitate the installation of the new
bar.
2. Upon removal of the half wall at the elevator lobby, a steel
angle imbedded in the floor slab was uncovered. Since this
angle would have been exposed in the new room, it was
necessary to remove it with a cutting torch.
3. When the existing slab was exposed, it was found to be made of
structural concrete. It was therefore, concluded to change
the new slab from insulating concrete to structural
lightweight concrete. The purpose of this change was to be
more compatible with the existing materials. Structural
lightweight concrete material is more expensive, requires a
larger pump and more labor to place and finish.
4. Two telephone outlets were requested by the City.
5. After installation of the gypsum board soffit, it was
discovered that the T-Grid cei 1 ing supports at the perimeter
would not permit thc acccss doors to the light tubes to be
opened. Therefore, six (6) light fixtures were returned for
credit and T-Grid ceiling tiles were added at the perimeter.
This change allows for easier changing of light tubes.
6. At the City's l"equest, incanclescent down lights were added
over the countcr area.
7. To assure propcr matching of old and new work, painting of the
cntire Lobby ceiling was added to the contract.

8.
With the addition of the 1/2" bardwood plywood, the doors
becam~ 2 1/4" tbick. The increased duor tbickness made it
necessary to increase the lc.ngth of the locksets. This was a
custom operation \'Ihich reglJired the lockset to be dismantled
in order to have a longer shaft welded into place.
9.
To prevent futnre door wal'page and strengthen the large doors,
covering the marker board mad~ it necessary to dismcntle the
doors and add steel angle stiffeners. Please note the
architect has observed a 3/4" gap between the doors and cannot
authorize the payment of this item until the doors close
together with no gap.
10. No price change authorized.
11. The above changes required sixteen hours of additional
supervision at a rate of approximately $31.00 per hour.
12. The cabinet maker was allowed to alter the edge band detail
which made it possible to use his edge banding machine. The
credit reflects his savings in labor.
Overall, we find these costs to be fair and a reasonable reflection of
today's construction industry costs.
Sincerely,
ROGER L. GRULKE, ARCHITECTS & ASSOCIATES, INC.
