Just like that.

should be “办公场所”instead of “办公场合”“场合”is a situation, referring to the ambiens, atmospheres considering the purposes of a gathering, who is present, what the theme is, etc. for example, where a wedding is going on, or official meeting is being held and so on; while “场所” is just a place for work, "workplace" is what some of our American partners use officially for their offices or office buildings and related working facilities during our business talks. “场合” can not be decorated, but workplaces can be decorated or arranged in different styles for different “场合”。

Dressing up for work can just as hard as dressing down. Dressy office occasions include dinner with a client,dinner at the boss's house,a banquet,a client's party,or an office holiday.
为工作精心着装与轻松着装一样不易，为办公场合精心着装一番包括与客户共同进餐，在老板家吃饭，参加宴会、客户举办的晚会或办公室节日等等

My 2 cents...
One other caution: In some social contexts, particularly in an office or a professional setting, greetings between the sexes should be very conservative.
另一项值得注意的：在某种社交场合，尤其是在办公室或专业场合里，两性之间的问候应该非常保守。

办工场合 can mean office, when this phrase is read in the contex of the sentence ...办工场合的装修.....， it would mean the renovation to the Office Premise.
