Wadan Engineering Services proudly shares a glimpse into the ongoing World Bank-funded project in Peshawar, part of the KP-Human Capital Investment Project. The recently unveiled progress video showcases the initial stages of constructing and upgrading schools, laying the foundation for a brighter future. The dedicated efforts of Team Wadan are evident in every detail, from the carefully planned classrooms to the emerging structures that promise to become educational havens. This is more than just construction; it's a collaborative creation of opportunities and dreams. Gratitude extends to the local communities whose support is woven into the very fabric of this transformative initiative. As the project unfolds, stay connected for more updates, and join us in painting a vibrant portrait of educational evolution in Khyber Pakhtunkhwa.

ACI 306 “Cold Weather Concreting” defines cold weather concreting as a period when for
more than three (3) consecutive days, the following conditions exist:
• The average daily air temperature is less than 5°C (40°F) and,
• The air temperature is not greater than 10°C (50°F) for more than one-half of any
24 hour period.
Even though not defined as cold weather, protection during Spring and Fall is required during
the first 24 hours to avoid freezing.

What Happens When Concrete Freezes?
• Pore water in concrete starts to freeze around -1°C (30°F)
• As some water freezes the ion concentration in the unfrozen water goes up, further
depressing the freezing point.
• At around -3 to -4°C (25 to 27°F), enough of the pore water will freeze so that hydration
will completely stop, and depending on the extent of hydration, and thus the strength of the
concrete, the forces generated by the expansion of ice (ice occupies ~9% more volume
than water) may be detrimental to the long term integrity of the concrete.
