RE: Saint Paul Civic Center Expansion
Level 4 Formwork
Dear Ron:
���
We are in receipt of your fetter, dated S January 1997, requesting additional compensation for
Level 4 formwork. It should be recognized the level of cracking and vibration expected from your
form removal design is unacceptable per the Uniform Building Code requirements and therefore is
unacceptable to the Owner. The design presented by MAM is adequate for ultimate load capacity
but does not consider the condition of the fi�al product. Your form removal sequence exceeds the
cracking limit of the concrete and therefore does not perform as intended.
Recognizing the magnitude of your problem the Owner provided the services of FIGA to research
economicaf so(utions. To date they have analyzed a selective removal plan at Pour #5 and they
have reviewed Pour #8 for stripping prior to placement of Pour #9. In addition, the testing engineer
performed grout tests which HGA has determined to be of adequate strength at two days cure.
MAM, HGA, CPM1 and tfie contractors worked jointly to review and resolve this in an expeditious
manner.
We take exception to the two cost related items:
1. Ceco has established with its expert that reshoring should have been expected. In
addition, with HGA's recent review on Pours #8 and #9, the scope your letter
references has changed.
2. Per Section 03100, Paragraph 3.7.D: "Design forms for safety in removal and in proper
sequence without damage to concrete. Provide removable side forms for beams and
slabs to enable removal without disturbing bottom forms or shoring beneath them." If
the formwork was designed per this requirement, side form removal should not be an
issue.
We take the position that incorrect assumptions relating to form design is a contractor issue. lf
these incorrect assumptions negatively impact the schedule then the Owner will require the
contractor develop a recovery position. However, it is our understanding that Level 4 formwork
and shoring has not negatively affected the schedufe.

The costs presented to us in yourletter dated 6 January �997 are not acceptable. We propose
that you delete any charges for beam sides and provide a credit for the reshoring which should
have been provided for in the base bid. Resubmit your request for additional compensation at the
Level 4 formwork with consideration of these issues.
Thank you.

Ron:
Susan Jones had asked me to geY an opinion from a third party an ths shoring
f2qUf1'�meiltS fOr {eve4 4. i had mentioned to you that I discussad the shoring
reqUirement for level 4 with several peoplc knowiedgeable in eoncreta formwnrk
and post-tensioning and afi agreed that what was being askad couid not be
anticipated, but I was looking for an individua4 with whose opinion, CPMi would
be comfortable. �n a racent meefing, Paui Asp, HGA presented a copy of AC1-
347, 2 Guide t0 Formwark for Goncrete, and indicated that those experienced in
fOfming tYtiS type of structure shoutd have anticipted what was being asked. So, I
thought a fiair person to contaci would bG th� chairman of ACI-347.
Hi5 name ts Sam Greenberg. He's a structural consultant for Dansco
Engineering in Apollo Beach F�ofid2. He has over 20 years of experienc� in
deS�gning concrete structures as well as formwork design. We sent $acn tha
structurai +nformation (transmittai attac ou�s shored atone woutd Ot be
HGA`s request to leav� iwo adjaCent p
anticipated and pointed out that such requirements shouid be addressed in the
bid documents. He went on to say that even after analyz�ng the design, teaving
the shoring in after grouting was not necessary- He suggested putting somc
reshoring in after gro�ting and stripping to take care of any additionaf cnncerns
th� engineer may have with deftection. shrinkage and creep. i've attached a
copy of Sam�s written comments.
Hopefu[ty, Sarrt Greenberg's comments wiii be enough backup to our fnit+al
statement that the additional shoring HGA is requiring could not have been
anticipated. We are proceeding with Aaul Asp's shoringlstripping procedure of
leaving two ad}'acent bays in piace and are making up the additional materials as
we discussect� { wilt forward khe eosts under separate cover.
