Learning Viewpoint

The first intervention of the Cerro Blanco Protected Forest master plan faces the visitors to the forest magnitude. The design promotes the collective experience of being sitting in the front row. The end of the main axis lets the guide or the teacher the best location to address the audience spread in the two lateral wings. With this action, the viewpoint works as an open classroom for the school groups that visit the forest, which represents the largest park visitors.

這是布蘭科山（Cerro Blanco）森林保護總體規劃的第一個改造項目，將遊客的目光引向壯闊的森林景觀中。該設計強調了坐在前排的集體體驗，主要軸線的末端為導遊或老師提供了最佳位置，方便他們面向分布在兩側的觀眾。有了這一設施，該觀景台成為學校團體參觀森林的開放教室，也是該公園的主要遊客。

成為計劃的第一個項目，觀景台在此計畫作為一個實體模型，使我們能夠了解這個計劃在建築改造中的整體應用技術範疇。常見的木材以簡單的方式組裝，形成了一個不平凡也不簡單的結構；該建築不需要任何修飾，其原始功能及結構的簡單性能夠使人們感到舒適、安全，此觀景台的木材甚至沒有上漆，其深色來自日本的傳統燒杉技術；該技術燃燒木材表面，使其礦化，從而保護它免受可能的害蟲侵襲。

Being the first project of the plan, the viewpoint works as a prototype that allowed us to understand the whole scope of the technology that we are planning to apply in the architectonic interventions. Common pieces of wood were assembled in a simple way, getting something that is neither common nor simple; the architecture dispenses of final finishes and its primitive form is enough to contain us. The viewpoint wood is not even painted, its darkness is due to a vernacular Japanese method of wood preserving; it burns the surface layer, this mineralizes and protects it from pests that could attack it.

Plan

The timber structure that lets landscape contemplation is covered with a canvas impregnated with a cementitious mortar suspended in a tensioned structure. Guayaquil Holcim Innovation Center, researched and developed a hybrid adaptive geometry roof, using a high-strength mortar sprayed on a textile.

這個專門讓人欣賞景觀的木造結構，其表面覆蓋了一層浸透有水泥砂漿的帆布，懸掛在一個扎實拉緊的結構上。瓜亞基爾霍爾希姆（Holcim）創新中心，研究開發了一種幾何形狀可視需求環境彈性調整的屋頂，並使用高強度砂漿噴灑在紡織物上。

Based on bibliographic references, the use of a flexible textile formwork comes from years post World War I, where its first use was organic fabrics for marine engineering and geotechnical applications. With this starting point, multiple tests were carried out in the lab to evaluate fabrics of different compositions, stiffness, and elongation. The main goal was to evaluate the compatibility and adhesion capacity with the cementitious mortar, so, the textile would act as an air-suspended "formwork". The mortar was technically designed to obtain high initial strengths and fluidity for the projection and the necessary consistency to adhere it and additionally provide low permeability in the hardened state protecting the textile from weathering and UV degradation.

根據文獻參考，彈性紡織模板的使用起源於第一次世界大戰後的幾年，當時使用的是有機布料，應用於海洋以及地質工程。基於這個出發點，實驗室進行了多次試驗，評估不同成份、硬度和延展性的布料。主要目的是評估其布料與水泥砂漿的相容性和附著效果，使紡織品作為一種吊掛空中的「模板」。此砂漿在技術上設計成具有高初期強度和流動性，以進行噴灑，且具有必要的粘度使其粘附，並在硬化狀態下具有低滲透性，保護紡織品免於因受風化和紫外線而劣化。

Several prototypes were tested in the lab and on-site to achieve the best mortar projection system and the maximum allowable textile catenary deformation, all of these before the final assembly on the viewpoint.

實驗室及現場測試了數個模型，以達到最佳的砂漿噴灑系統及紡織品最大尺度的懸垂變形。這些測試完成後，即在觀景點進行最終組裝。

Through a life cycle analysis, Guayaquil Holcim Innovation Center determine a 68% reduction of the carbon footprint embedded in its materials with respect to a concrete tile roof per square meter.

瓜亞基爾霍爾希姆創新中心透過其生命週期分析，確定其材料相較於每平方米的混凝土屋頂，碳排放減少了68%。這也說明了他們在環保方面的積極努力和創新的成果。
