CREATE TABLE mill (architect_id DECIMAL, id DECIMAL, location TEXT, name TEXT, type TEXT, built_year DECIMAL, notes TEXT)
CREATE TABLE bridge (architect_id DECIMAL, id DECIMAL, name TEXT, location TEXT, length_meters DECIMAL, length_feet DECIMAL)
CREATE TABLE architect (id TEXT, name TEXT, nationality TEXT, gender TEXT)

What are the ids and names of the architects who built at least 3 bridges ?
SELECT T1.id, T1.name FROM architect AS T1 JOIN bridge AS T2 ON T1.id = T2.architect_id GROUP BY T1.id HAVING COUNT(*) >= 3
SELECT "T1"."id", "T1"."name" FROM "architect" AS "T1" JOIN "bridge" AS "T2" ON "T1"."id" = "T2"."architect_id" GROUP BY "T1"."id" HAVING COUNT(*) >= 3
