I'm sorry to be the bearer of bad news, but if you don't have a work visa, you'd be working illegally and there are very few, if any, job openings for non-Spanish speakers on tourist visas in the construction industry. As the bigger constructors are mainly unionised, in most areas it's also a closed shop to outsiders, Peruvians and foreigners.
On this website, I've occasionally seen threads from English-speaking entrepreneurs in the business section, some of which involve construction-related work, although mostly the threads are to do services like tourism, call centres and restaurants. So I'd suggest just going through all the old posts. There's also the jobs section, but it seems to be mainly ads for English teachers and tourism-related jobs. And even if you find something, pay is usually very poor. There's a reason North America and Northern Europe gets lots of economic migrants, more jobs, higher pay. Good luck.
