pragma solidity 0.5.0+;
contract Survey {
    /* Events */
     event SurveyInitialized(address indexed owner, uint indexed surveyReward);

    /* Contract State */
    address public owner;
    address private factory;

    Constructor Survey(address _owner) payable public {
        (_owner != address(0));
        (msg.value > 0);
        owner = _owner;
        factory = msg.sender;
        emit SurveyInitialized(owner, msg.value);
    }
}

the error :

browser/checkbalance.sol:12:20: ParserError: Expected ';' but got '(' Constructor Survey (address _owner) payable public

You don't need to put any name after constructor. Just write it as :

constructor (address _owner) payable public

Also change your pragma to:

pragma solidity ^0.5.0;

for better results.
