Hi there, and welcome!
I'm SO not an expert on construction workers and weight loss, but I do have some thoughts, so take it for what it is worth:
First of all, I think that your idea to count calories is great. I found a guide here that can help you calculate what you need, and it specifically mentions working in construction:

We all need a minimum number of calories simply to survive, but we can also set a calorie limit to maintain a healthy weight. You can calculate the total number of calories you need for your type of lifestyle, then use this figure to decide on a range of calories to consume each day - it's not an absolute figure.
Steps:
1. Calculate the minimum number of calories you need by multiplying your current or desired weight in pounds by 10 if you're a woman, 11 if you're a man. This number represents your basic calorie needs.
2. Calculate the number of calories required for your activity level (see tips, below) by multiplying your basic calorie needs (the calculation from step 1) by your activity level - 20 percent or 0.2, 30 percent or 0.3, 40 percent or 0.4, or 50 percent or 0.5. The resulting number represents your activity-based calorie needs.
3. Calculate the number of calories your body needs for food digestion and absorption by adding your basic calorie needs and your activity-based calorie needs (the answers from steps 1 and 2) and multiplying this sum by 0.10. These are the calories you need for digestion.
4. Add the three calculations from steps 1, 2 and 3: This is your total daily calorie need to maintain your desired weight.
Tips:
Use the following as a guideline for determining your activity level: 20 percent if you sit or lie still for most of the day, with little or no exercise; 30 percent if you walk less than two miles per day; 40 percent if you are somewhat active, doing activities such as dancing, doing a lot of work in the house or garden, or taking exercise classes; and 50 percent if you're actively involved in a sport or you have job that requires a great deal of physical labor, such as construction work.
There are 3,500 calories in a pound, so to lose one pound per week, you need to decrease your calorie intake by 3,500 calories a week, or 500 calories a day.
My second gut feeling is that you are plenty active right now. It might be a great idea to focus on your eating plan first, to get comfy with it and to see what happens when you stay within your calorie levels at your current activity level. Construction work is HARD, and you might be getting enough of a workout as it is.
And if you plan for a 1-2 lb per week weight loss, I don't think you'll have to worry much about protein supplementation and so on, because at this rate of loss, the vast majority of the lost mass is fat, not muscle.
There are other calorie counters there, so you might want to post on the Calorie Counters Forum, located on the main page, for more expert advice from those who have alot more experience at it that I have.
Let us know how it goes!
