If you do not have one in your company at present, now is the perfect time to make one before it is too late. Do not wait for someone to get hurt while working in your construction site. It will put you in too much trouble especially if found out that there is no construction safety plan in place. Keep away from legal suits and paying huge fines.
However, if you do not want to spend money or you cannot find one that would suit your training ideas, then try the integrated approach. You can look up other companies' templates online and then make a few revisions to make it fit your own approach. If you are lucky, you might even stumble upon a training plan template from a company that is within the industry your business belongs to.
