The Construction History Society of North America, together with UNAM’s School of Architecture and the Master’s and Doctoral Program in Architecture, announces the call for abstracts for the 10th Congress of the Construction History Society of North America and the 1st Mexico–USA Binational Congress. This event will take place at the **Universidad Nacional Autónoma de México (UNAM) in Mexico City, from June 3rd to 6th, 2026.

Researchers and professionals from all fields of construction history are invited to submit paper abstracts for the **2026 Meeting on Construction History**, to be held at **Ciudad Universitaria**. The Program Committee seeks a wide range of papers related to construction history, including physical outcomes such as infrastructure and buildings, as well as materials, processes, and systems used in their development. While diverse periods and geographies are welcome, topics focused on the Americas will be given special priority.

Accepted abstracts will be included in a printed catalog distributed during the meeting, and presenters will deliver their papers in **20-minute sessions**.

Curated proceedings, consisting of full papers between **4,000 and 6,000 words**, will be compiled and edited by the Scientific Committee after the conference for publication in a **special issue of the journal Construction History** (further details to be provided). Alternatively, CHSA encourages authors to submit their full papers directly to *Construction History* according to its editorial calendar. Submission of an abstract for the CHSA Meeting does not exempt papers from the journal’s peer-review process.

Each abstract must include:

- Author names and institutional affiliations

- An abstract of up to 400 words

- Keywords (selected, if possible, from the list of topics and themes)

- A brief biography with contact information, academic or professional affiliation, and relevant work for each author [maximum 250 words]

Presentations may be in **English or Spanish**. Please include **4–5 learning objectives** for AIA CES documentation purposes. Abstract topics may include:
