Spearhead Impact of Steel Spearhead Lost Productivity

Impact of Steel

Inconsistent floor slope; Concrete added to elevate FF Each base “scribed” to uneven floor (south --> north; west --> east) Pitch caused multiple comebacks / revisions Changed ceiling elevations (Example: 3x @ North elevator lobby) Created numerous ”hits” with other trades (pipes/ductwork) GFRG Soffit flares would not line up w/o substantial modification Had to fabricate gyp soffit flares - unexpected Required continuous elevation verifications with HOK and SWJV Found conditions led to field modifications and sequential installation Access lines no longer centered on trusses Clips field-modified (extended or cut back) Framing field-modified (“ripping” studs at angle / taper) GFRG/C pieces field modified (shaved back @ bolts) Required vigilance to hold correct line of tapered tips of each chamfered edge Forced sequential installation; could not deploy independent crews, working concurrently

Bridge "dropped"

Roof "dipped"

Out of plumb

Bolts backwards

Plasterform quoted additional $70k to accommodate Spearhead forced to absorb labor costs and lost time to modify in the field
