1. SCOPE OF SPECIFICATION
This specification includes the general information to be
considered by a Bidder while preparing a proposal.
2. PROJECT LOCATION
The Cerro Verde mine is situated 16 km east-southeast of
Arequipa, capital of the Province of Arequipa and second largest
city in Peru.
Project elevation: 2700 m above sea level (8860 ft) Project
latitude: 16 32 south Project longitude: 71 37 west
3. SITE ACCESS
The mine is connected by paved roads to: Arequipa, a distance of
26 km, Pacific port of Matarani, a distance of 100 km Lima, the
countrys capital, approximately a distance of 1100 km.
The Southern Railway of Peru from Matarani to Arequipa passes
within 12 km of the mine site.

H. Earthquake
1. Earthquake loads are defined as the static horizontal and
vertical forces equivalent in their design effect to the dynamic
loads induced by ground motion during an earthquake.
2. All buildings, structures, and components shall be designed
for earthquake forces according to the International Building Code
(IBC), 2003 Edition and the following factors:
a) Ss = 0.8 g (Spectral acceleration for 0.2 sec. Period) b) S1
= 0.4 g (Spectral acceleration for 1.0 sec. Period) c) Fa = 1 (Site
coefficient defined in Table 1615.1.2.(1) d) Fv = 1 (Site
coefficient defined in Table 1615.1.2.(2) e) Site class = B (IBC
Table 1615.1.1)
3. Seismic design for circular storage tanks at grade shall be
according to Appendix E of API Standard 650. The effect of slosh
height on freeboard and tank roof shall be considered,
4. Seismic load is the total dead or operating load, whichever
is worse, and applicable portion of other loads as defined in IBC
sections 1616 to 1622.
5. Tall structures and structures having stiffness, weight, or
geometric irregularities as defined in IBC Section 1616.5 shall be
analyzed using dynamic lateral force procedures of Section 1618,
including appropriate scaling of the results.
